Summary

synchronize_rcu() to immediately return breaks RCU, even on a UP system.

Answer to Quick Quiz #3:

Why can't synchronize_rcu() return immediately on UP systems

Because some other task might have been preempted in the middle

S3C24XX CPUfreq support
|
||||
=======================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
The S3C24XX series support a number of power saving systems, such as
|
||||
the ability to change the core, memory and peripheral operating
|
||||
frequencies. The core control is exported via the CPUFreq driver
|
||||
which has a number of different manual or automatic controls over the
|
||||
rate the core is running at.
|
||||
|
||||
There are two forms of the driver depending on the specific CPU and
|
||||
how the clocks are arranged. The first implementation used as single
|
||||
PLL to feed the ARM, memory and peripherals via a series of dividers
|
||||
and muxes and this is the implementation that is documented here. A
|
||||
newer version where there is a seperate PLL and clock divider for the
|
||||
ARM core is available as a seperate driver.
|
||||
|
||||
|
||||
Layout
|
||||
------
|
||||
|
||||
The code core manages the CPU specific drivers, any data that they
|
||||
need to register and the interface to the generic drivers/cpufreq
|
||||
system. Each CPU registers a driver to control the PLL, clock dividers
|
||||
and anything else associated with it. Any board that wants to use this
|
||||
framework needs to supply at least basic details of what is required.
|
||||
|
||||
The core registers with drivers/cpufreq at init time if all the data
|
||||
necessary has been supplied.
|
||||
|
||||
|
||||
CPU support
|
||||
-----------
|
||||
|
||||
The support for each CPU depends on the facilities provided by the
|
||||
SoC and the driver as each device has different PLL and clock chains
|
||||
associated with it.
|
||||
|
||||
|
||||
Slow Mode
|
||||
---------
|
||||
|
||||
The SLOW mode where the PLL is turned off altogether and the
|
||||
system is fed by the external crystal input is currently not
|
||||
supported.
|
||||
|
||||
|
||||
sysfs
|
||||
-----
|
||||
|
||||
The core code exports extra information via sysfs in the directory
|
||||
devices/system/cpu/cpu0/arch-freq.
|
||||
|
||||
|
||||
Board Support
|
||||
-------------
|
||||
|
||||
Each board that wants to use the cpufreq code must register some basic
|
||||
information with the core driver to provide information about what the
|
||||
board requires and any restrictions being placed on it.
|
||||
|
||||
The board needs to supply information about whether it needs the IO bank
|
||||
timings changing, any maximum frequency limits and information about the
|
||||
SDRAM refresh rate.

README for btmrvl driver
|
||||
=======================================================================
|
||||
|
||||
|
||||
All commands are used via debugfs interface.
|
||||
|
||||
=====================
|
||||
Set/get driver configurations:
|
||||
|
||||
Path: /debug/btmrvl/config/
|
||||
|
||||
gpiogap=[n]
|
||||
hscfgcmd
|
||||
These commands are used to configure the host sleep parameters.
|
||||
bit 8:0 -- Gap
|
||||
bit 16:8 -- GPIO
|
||||
|
||||
where GPIO is the pin number of GPIO used to wake up the host.
|
||||
It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface
|
||||
wakeup will be used instead).
|
||||
|
||||
where Gap is the gap in milli seconds between wakeup signal and
|
||||
wakeup event, or 0xff for special host sleep setting.
|
||||
|
||||
Usage:
|
||||
# Use SDIO interface to wake up the host and set GAP to 0x80:
|
||||
echo 0xff80 > /debug/btmrvl/config/gpiogap
|
||||
echo 1 > /debug/btmrvl/config/hscfgcmd
|
||||
|
||||
# Use GPIO pin #3 to wake up the host and set GAP to 0xff:
|
||||
echo 0x03ff > /debug/btmrvl/config/gpiogap
|
||||
echo 1 > /debug/btmrvl/config/hscfgcmd
|
||||

What: PRISM54
|

When: 2.6.34
|
||||
|
||||
Why: prism54 FullMAC PCI / Cardbus devices used to be supported only by the
|
||||
prism54 wireless driver. After Intersil stopped selling these
|
||||
devices in preference for the newer more flexible SoftMAC devices
|
||||
a SoftMAC device driver was required and prism54 did not support
|
||||
them. The p54pci driver now exists and has been present in the kernel for
|
||||
a while. This driver supports both SoftMAC devices and FullMAC devices.
|
||||
The main difference between these devices was the amount of memory which
|
||||
could be used for the firmware. The SoftMAC devices support a smaller
|
||||
amount of memory. Because of this the SoftMAC firmware fits into FullMAC
|
||||
devices's memory. p54pci supports not only PCI / Cardbus but also USB
|
||||
and SPI. Since p54pci supports all devices prism54 supports
|
||||
you will have a conflict. I'm not quite sure how distributions are
|
||||
handling this conflict right now. prism54 was kept around due to
|
||||
claims users may experience issues when using the SoftMAC driver.
|
||||
Time has passed users have not reported issues. If you use prism54
|
||||
and for whatever reason you cannot use p54pci please let us know!

What: libata spindown skipping and warning
|

Why: Some halt(8) implementations synchronize caches for and spin

down libata disks because libata didn't use to spin down disk on

Spin down on system halt is now implemented. sysfs node

/sys/class/scsi_disk/h:c:i:l/manage_start_stop is present if

spin down support is available.
|

Because issuing spin down command to an already spun down disk
|

makes some disks spin up just to spin down again, libata tracks
|

device spindown status to skip the extra spindown command and

warn about it.

This is to give userspace tools the time to get updated and will

uevents and GFS2
|
||||
==================
|
||||
|
||||
During the lifetime of a GFS2 mount, a number of uevents are generated.
|
||||
This document explains what the events are and what they are used
|
||||
for (by gfs_controld in gfs2-utils).
|
||||
|
||||
A list of GFS2 uevents
|
||||
-----------------------
|
||||
|
||||
1. ADD
|
||||
|
||||
The ADD event occurs at mount time. It will always be the first
|
||||
uevent generated by the newly created filesystem. If the mount
|
||||
is successful, an ONLINE uevent will follow. If it is not successful
|
||||
then a REMOVE uevent will follow.
|
||||
|
||||
The ADD uevent has two environment variables: SPECTATOR=[0|1]
|
||||
and RDONLY=[0|1] that specify the spectator status (a read-only mount
|
||||
with no journal assigned), and read-only (with journal assigned) status
|
||||
of the filesystem respectively.
|
||||
|
||||
2. ONLINE
|
||||
|
||||
The ONLINE uevent is generated after a successful mount or remount. It
|
||||
has the same environment variables as the ADD uevent. The ONLINE
|
||||
uevent, along with the two environment variables for spectator and
|
||||
RDONLY are a relatively recent addition (2.6.32-rc+) and will not
|
||||
be generated by older kernels.
|
||||
|
||||
3. CHANGE
|
||||
|
||||
The CHANGE uevent is used in two places. One is when reporting the
|
||||
successful mount of the filesystem by the first node (FIRSTMOUNT=Done).
|
||||
This is used as a signal by gfs_controld that it is then ok for other
|
||||
nodes in the cluster to mount the filesystem.
|
||||
|
||||
The other CHANGE uevent is used to inform of the completion
|
||||
of journal recovery for one of the filesystems journals. It has
|
||||
two environment variables, JID= which specifies the journal id which
|
||||
has just been recovered, and RECOVERY=[Done|Failed] to indicate the
|
||||
success (or otherwise) of the operation. These uevents are generated
|
||||
for every journal recovered, whether it is during the initial mount
|
||||
process or as the result of gfs_controld requesting a specific journal
|
||||
recovery via the /sys/fs/gfs2/<fsname>/lock_module/recovery file.
|
||||
|
||||
Because the CHANGE uevent was used (in early versions of gfs_controld)
|
||||
without checking the environment variables to discover the state, we
|
||||
cannot add any more functions to it without running the risk of
|
||||
someone using an older version of the user tools and breaking their
|
||||
cluster. For this reason the ONLINE uevent was used when adding a new
|
||||
uevent for a successful mount or remount.
|
||||
|
||||
4. OFFLINE
|
||||
|
||||
The OFFLINE uevent is only generated due to filesystem errors and is used
|
||||
as part of the "withdraw" mechanism. Currently this doesn't give any
|
||||
information about what the error is, which is something that needs to
|
||||
be fixed.
|
||||
|
||||
5. REMOVE
|
||||
|
||||
The REMOVE uevent is generated at the end of an unsuccessful mount
|
||||
or at the end of a umount of the filesystem. All REMOVE uevents will
|
||||
have been preceeded by at least an ADD uevent for the same fileystem,
|
||||
and unlike the other uevents is generated automatically by the kernel's
|
||||
kobject subsystem.
|
||||
|
||||
|
||||
Information common to all GFS2 uevents (uevent environment variables)
|
||||
----------------------------------------------------------------------
|
||||
|
||||
1. LOCKTABLE=
|
||||
|
||||
The LOCKTABLE is a string, as supplied on the mount command
|
||||
line (locktable=) or via fstab. It is used as a filesystem label
|
||||
as well as providing the information for a lock_dlm mount to be
|
||||
able to join the cluster.
|
||||
|
||||
2. LOCKPROTO=
|
||||
|
||||
The LOCKPROTO is a string, and its value depends on what is set
|
||||
on the mount command line, or via fstab. It will be either
|
||||
lock_nolock or lock_dlm. In the future other lock managers
|
||||
may be supported.
|
||||
|
||||
3. JOURNALID=
|
||||
|
||||
If a journal is in use by the filesystem (journals are not
|
||||
assigned for spectator mounts) then this will give the
|
||||
numeric journal id in all GFS2 uevents.
|
||||
|
||||
4. UUID=
|
||||
|
||||
With recent versions of gfs2-utils, mkfs.gfs2 writes a UUID
|
||||
into the filesystem superblock. If it exists, this will
|
||||
be included in every uevent relating to the filesystem.

The NFS client
|
||||
==============
|
||||
|
||||
The NFS version 2 protocol was first documented in RFC1094 (March 1989).
|
||||
Since then two more major releases of NFS have been published, with NFSv3
|
||||
being documented in RFC1813 (June 1995), and NFSv4 in RFC3530 (April
|
||||
2003).
|
||||
|
||||
The Linux NFS client currently supports all the above published versions,
|
||||
and work is in progress on adding support for minor version 1 of the NFSv4
|
||||
protocol.
|
||||
|
||||
The purpose of this document is to provide information on some of the
|
||||
upcall interfaces that are used in order to provide the NFS client with
|
||||
some of the information that it requires in order to fully comply with
|
||||
the NFS spec.
|
||||
|
||||
The DNS resolver
|
||||
================
|
||||
|
||||
NFSv4 allows for one server to refer the NFS client to data that has been
|
||||
migrated onto another server by means of the special "fs_locations"
|
||||
attribute. See
|
||||
http://tools.ietf.org/html/rfc3530#section-6
|
||||
and
|
||||
http://tools.ietf.org/html/draft-ietf-nfsv4-referrals-00
|
||||
|
||||
The fs_locations information can take the form of either an ip address and
|
||||
a path, or a DNS hostname and a path. The latter requires the NFS client to
|
||||
do a DNS lookup in order to mount the new volume, and hence the need for an
|
||||
upcall to allow userland to provide this service.
|
||||
|
||||
Assuming that the user has the 'rpc_pipefs' filesystem mounted in the usual
|
||||
/var/lib/nfs/rpc_pipefs, the upcall consists of the following steps:
|
||||
|
||||
(1) The process checks the dns_resolve cache to see if it contains a
|
||||
valid entry. If so, it returns that entry and exits.
|
||||
|
||||
(2) If no valid entry exists, the helper script '/sbin/nfs_cache_getent'
|
||||
(may be changed using the 'nfs.cache_getent' kernel boot parameter)
|
||||
is run, with two arguments:
|
||||
- the cache name, "dns_resolve"
|
||||
- the hostname to resolve
|
||||
|
||||
(3) After looking up the corresponding ip address, the helper script
|
||||
writes the result into the rpc_pipefs pseudo-file
|
||||
'/var/lib/nfs/rpc_pipefs/cache/dns_resolve/channel'
|
||||
in the following (text) format:
|
||||
|
||||
"<ip address> <hostname> <ttl>\n"
|
||||
|
||||
Where <ip address> is in the usual IPv4 (123.456.78.90) or IPv6
|
||||
(ffee:ddcc:bbaa:9988:7766:5544:3322:1100, ffee::1100, ...) format.
|
||||
<hostname> is identical to the second argument of the helper
|
||||
script, and <ttl> is the 'time to live' of this cache entry (in
|
||||
units of seconds).
|
||||
|
||||
Note: If <ip address> is invalid, say the string "0", then a negative
|
||||
entry is created, which will cause the kernel to treat the hostname
|
||||
as having no valid DNS translation.

Using flexible arrays in the kernel
|
||||
Last updated for 2.6.31
|
||||
Jonathan Corbet <corbet@lwn.net>
|
||||
|
||||
Large contiguous memory allocations can be unreliable in the Linux kernel.
|
||||
Kernel programmers will sometimes respond to this problem by allocating
|
||||
pages with vmalloc(). This solution not ideal, though. On 32-bit systems,
|
||||
memory from vmalloc() must be mapped into a relatively small address space;
|
||||
it's easy to run out. On SMP systems, the page table changes required by
|
||||
vmalloc() allocations can require expensive cross-processor interrupts on
|
||||
all CPUs. And, on all systems, use of space in the vmalloc() range
|
||||
increases pressure on the translation lookaside buffer (TLB), reducing the
|
||||
performance of the system.
|
||||
|
||||
In many cases, the need for memory from vmalloc() can be eliminated by
|
||||
piecing together an array from smaller parts; the flexible array library
|
||||
exists to make this task easier.
|
||||
|
||||
A flexible array holds an arbitrary (within limits) number of fixed-sized
|
||||
objects, accessed via an integer index. Sparse arrays are handled
|
||||
reasonably well. Only single-page allocations are made, so memory
|
||||
allocation failures should be relatively rare. The down sides are that the
|
||||
arrays cannot be indexed directly, individual object size cannot exceed the
|
||||
system page size, and putting data into a flexible array requires a copy
|
||||
operation. It's also worth noting that flexible arrays do no internal
|
||||
locking at all; if concurrent access to an array is possible, then the
|
||||
caller must arrange for appropriate mutual exclusion.
|
||||
|
||||
The creation of a flexible array is done with:
|
||||
|
||||
#include <linux/flex_array.h>
|
||||
|
||||
struct flex_array *flex_array_alloc(int element_size,
|
||||
unsigned int total,
|
||||
gfp_t flags);
|
||||
|
||||
The individual object size is provided by element_size, while total is the
|
||||
maximum number of objects which can be stored in the array. The flags
|
||||
argument is passed directly to the internal memory allocation calls. With
|
||||
the current code, using flags to ask for high memory is likely to lead to
|
||||
notably unpleasant side effects.
|
||||
|
||||
Storing data into a flexible array is accomplished with a call to:
|
||||
|
||||
int flex_array_put(struct flex_array *array, unsigned int element_nr,
|
||||
void *src, gfp_t flags);
|
||||
|
||||
This call will copy the data from src into the array, in the position
|
||||
indicated by element_nr (which must be less than the maximum specified when
|
||||
the array was created). If any memory allocations must be performed, flags
|
||||
will be used. The return value is zero on success, a negative error code
|
||||
otherwise.
|
||||
|
||||
There might possibly be a need to store data into a flexible array while
|
||||
running in some sort of atomic context; in this situation, sleeping in the
|
||||
memory allocator would be a bad thing. That can be avoided by using
|
||||
GFP_ATOMIC for the flags value, but, often, there is a better way. The
|
||||
trick is to ensure that any needed memory allocations are done before
|
||||
entering atomic context, using:
|
||||
|
||||
int flex_array_prealloc(struct flex_array *array, unsigned int start,
|
||||
unsigned int end, gfp_t flags);
|
||||
|
||||
This function will ensure that memory for the elements indexed in the range
|
||||
defined by start and end has been allocated. Thereafter, a
|
||||
flex_array_put() call on an element in that range is guaranteed not to
|
||||
block.
|
||||
|
||||
Getting data back out of the array is done with:
|
||||
|
||||
void *flex_array_get(struct flex_array *fa, unsigned int element_nr);
|
||||
|
||||
The return value is a pointer to the data element, or NULL if that
|
||||
particular element has never been allocated.
|
||||
|
||||
Note that it is possible to get back a valid pointer for an element which
|
||||
has never been stored in the array. Memory for array elements is allocated
|
||||
one page at a time; a single allocation could provide memory for several
|
||||
adjacent elements. The flexible array code does not know if a specific
|
||||
element has been written; it only knows if the associated memory is
|
||||
present. So a flex_array_get() call on an element which was never stored
|
||||
in the array has the potential to return a pointer to random data. If the
|
||||
caller does not have a separate way to know which elements were actually
|
||||
stored, it might be wise, at least, to add GFP_ZERO to the flags argument
|
||||
to ensure that all elements are zeroed.
|
||||
|
||||
There is no way to remove a single element from the array. It is possible,
|
||||
though, to remove all elements with a call to:
|
||||
|
||||
void flex_array_free_parts(struct flex_array *array);
|
||||
|
||||
This call frees all elements, but leaves the array itself in place.
|
||||
Freeing the entire array is done with:
|
||||
|
||||
void flex_array_free(struct flex_array *array);
|
||||
|
||||
As of this writing, there are no users of flexible arrays in the mainline
|
||||
kernel. The functions described here are also not exported to modules;
|
||||
that will probably be fixed when somebody comes up with a need for it.

Intel(R) TXT Overview:
|
||||
=====================
|
||||
|
||||
Intel's technology for safer computing, Intel(R) Trusted Execution
|
||||
Technology (Intel(R) TXT), defines platform-level enhancements that
|
||||
provide the building blocks for creating trusted platforms.
|
||||
|
||||
Intel TXT was formerly known by the code name LaGrande Technology (LT).
|
||||
|
||||
Intel TXT in Brief:
|
||||
o Provides dynamic root of trust for measurement (DRTM)
|
||||
o Data protection in case of improper shutdown
|
||||
o Measurement and verification of launched environment
|
||||
|
||||
Intel TXT is part of the vPro(TM) brand and is also available some
|
||||
non-vPro systems. It is currently available on desktop systems
|
||||
based on the Q35, X38, Q45, and Q43 Express chipsets (e.g. Dell
|
||||
Optiplex 755, HP dc7800, etc.) and mobile systems based on the GM45,
|
||||
PM45, and GS45 Express chipsets.
|
||||
|
||||
For more information, see http://www.intel.com/technology/security/.
|
||||
This site also has a link to the Intel TXT MLE Developers Manual,
|
||||
which has been updated for the new released platforms.
|
||||
|
||||
Intel TXT has been presented at various events over the past few
|
||||
years, some of which are:

Trusted Boot Project Overview:
|
||||
=============================
|
||||
|
||||
Trusted Boot (tboot) is an open source, pre- kernel/VMM module that
|
||||
uses Intel TXT to perform a measured and verified launch of an OS
|
||||
kernel/VMM.
|
||||
|
||||
It is hosted on SourceForge at http://sourceforge.net/projects/tboot.
|
||||
The mercurial source repo is available at http://www.bughost.org/
|
||||
repos.hg/tboot.hg.
|
||||
|
||||
Tboot currently supports launching Xen (open source VMM/hypervisor
|
||||
w/ TXT support since v3.2), and now Linux kernels.
|
||||
|
||||
|
||||
Value Proposition for Linux or "Why should you care?"
|
||||
=====================================================
|
||||
|
||||
While there are many products and technologies that attempt to
|
||||
measure or protect the integrity of a running kernel, they all
|
||||
assume the kernel is "good" to begin with. The Integrity
|
||||
Measurement Architecture (IMA) and Linux Integrity Module interface
|
||||
are examples of such solutions.
|
||||
|
||||
To get trust in the initial kernel without using Intel TXT, a
|
||||
static root of trust must be used. This bases trust in BIOS
|
||||
starting at system reset and requires measurement of all code
|
||||
executed between system reset through the completion of the kernel
|
||||
boot as well as data objects used by that code. In the case of a
|
||||
Linux kernel, this means all of BIOS, any option ROMs, the
|
||||
bootloader and the boot config. In practice, this is a lot of
|
||||
code/data, much of which is subject to change from boot to boot
|
||||
(e.g. changing NICs may change option ROMs). Without reference
|
||||
hashes, these measurement changes are difficult to assess or
|
||||
confirm as benign. This process also does not provide DMA
|
||||
protection, memory configuration/alias checks and locks, crash
|
||||
protection, or policy support.
|
||||
|
||||
By using the hardware-based root of trust that Intel TXT provides,
|
||||
many of these issues can be mitigated. Specifically: many
|
||||
pre-launch components can be removed from the trust chain, DMA
|
||||
protection is provided to all launched components, a large number
|
||||
of platform configuration checks are performed and values locked,
|
||||
protection is provided for any data in the event of an improper
|
||||
shutdown, and there is support for policy-based execution/verification.
|
||||
This provides a more stable measurement and a higher assurance of
|
||||
system configuration and initial state than would be otherwise
|
||||
possible. Since the tboot project is open source, source code for
|
||||
almost all parts of the trust chain is available (excepting SMM and
|
||||
Intel-provided firmware).
|
||||
|
||||
How Does it Work?
|
||||
=================
|
||||
|
||||
o Tboot is an executable that is launched by the bootloader as
|
||||
the "kernel" (the binary the bootloader executes).
|
||||
o It performs all of the work necessary to determine if the
|
||||
platform supports Intel TXT and, if so, executes the GETSEC[SENTER]
|
||||
processor instruction that initiates the dynamic root of trust.
|
||||
- If tboot determines that the system does not support Intel TXT
|
||||
or is not configured correctly (e.g. the SINIT AC Module was
|
||||
incorrect), it will directly launch the kernel with no changes
|
||||
to any state.
|
||||
- Tboot will output various information about its progress to the
|
||||
terminal, serial port, and/or an in-memory log; the output
|
||||
locations can be configured with a command line switch.
|
||||
o The GETSEC[SENTER] instruction will return control to tboot and
|
||||
tboot then verifies certain aspects of the environment (e.g. TPM NV
|
||||
lock, e820 table does not have invalid entries, etc.).
|
||||
o It will wake the APs from the special sleep state the GETSEC[SENTER]
|
||||
instruction had put them in and place them into a wait-for-SIPI
|
||||
state.
|
||||
- Because the processors will not respond to an INIT or SIPI when
|
||||
in the TXT environment, it is necessary to create a small VT-x
|
||||
guest for the APs. When they run in this guest, they will
|
||||
simply wait for the INIT-SIPI-SIPI sequence, which will cause
|
||||
VMEXITs, and then disable VT and jump to the SIPI vector. This
|
||||
approach seemed like a better choice than having to insert
|
||||
special code into the kernel's MP wakeup sequence.
|
||||
o Tboot then applies an (optional) user-defined launch policy to
|
||||
verify the kernel and initrd.
|
||||
- This policy is rooted in TPM NV and is described in the tboot
|
||||
project. The tboot project also contains code for tools to
|
||||
create and provision the policy.
|
||||
- Policies are completely under user control and if not present
|
||||
then any kernel will be launched.
|
||||
- Policy action is flexible and can include halting on failures
|
||||
or simply logging them and continuing.
|
||||
o Tboot adjusts the e820 table provided by the bootloader to reserve
|
||||
its own location in memory as well as to reserve certain other
|
||||
TXT-related regions.
|
||||
o As part of it's launch, tboot DMA protects all of RAM (using the
|
||||
VT-d PMRs). Thus, the kernel must be booted with 'intel_iommu=on'
|
||||
in order to remove this blanket protection and use VT-d's
|
||||
page-level protection.
|
||||
o Tboot will populate a shared page with some data about itself and
|
||||
pass this to the Linux kernel as it transfers control.
|
||||
- The location of the shared page is passed via the boot_params
|
||||
struct as a physical address.
|
||||
o The kernel will look for the tboot shared page address and, if it
|
||||
exists, map it.
|
||||
o As one of the checks/protections provided by TXT, it makes a copy
|
||||
of the VT-d DMARs in a DMA-protected region of memory and verifies
|
||||
them for correctness. The VT-d code will detect if the kernel was
|
||||
launched with tboot and use this copy instead of the one in the
|
||||
ACPI table.
|
||||
o At this point, tboot and TXT are out of the picture until a
|
||||
shutdown (S<n>)
|
||||
o In order to put a system into any of the sleep states after a TXT
|
||||
launch, TXT must first be exited. This is to prevent attacks that
|
||||
attempt to crash the system to gain control on reboot and steal
|
||||
data left in memory.
|
||||
- The kernel will perform all of its sleep preparation and
|
||||
populate the shared page with the ACPI data needed to put the
|
||||
platform in the desired sleep state.
|
||||
- Then the kernel jumps into tboot via the vector specified in the
|
||||
shared page.
|
||||
- Tboot will clean up the environment and disable TXT, then use the
|
||||
kernel-provided ACPI information to actually place the platform
|
||||
into the desired sleep state.
|
||||
- In the case of S3, tboot will also register itself as the resume
|
||||
vector. This is necessary because it must re-establish the
|
||||
measured environment upon resume. Once the TXT environment
|
||||
has been restored, it will restore the TPM PCRs and then
|
||||
transfer control back to the kernel's S3 resume vector.
|
||||
In order to preserve system integrity across S3, the kernel
|
||||
provides tboot with a set of memory ranges (kernel
|
||||
code/data/bss, S3 resume code, and AP trampoline) that tboot
|
||||
will calculate a MAC (message authentication code) over and then
|
||||
seal with the TPM. On resume and once the measured environment
|
||||
has been re-established, tboot will re-calculate the MAC and
|
||||
verify it against the sealed value. Tboot's policy determines
|
||||
what happens if the verification fails.
|
||||
|
||||
That's pretty much it for TXT support.

Configuring the System:
|
||||
======================
|
||||
|
||||
This code works with 32bit, 32bit PAE, and 64bit (x86_64) kernels.
|
||||
|
||||
In BIOS, the user must enable: TPM, TXT, VT-x, VT-d. Not all BIOSes
|
||||
allow these to be individually enabled/disabled and the screens in
|
||||
which to find them are BIOS-specific.
|
||||
|
||||
grub.conf needs to be modified as follows:
|
||||
title Linux 2.6.29-tip w/ tboot
|
||||
root (hd0,0)
|
||||
kernel /tboot.gz logging=serial,vga,memory
|
||||
module /vmlinuz-2.6.29-tip intel_iommu=on ro
|
||||
root=LABEL=/ rhgb console=ttyS0,115200 3
|
||||
module /initrd-2.6.29-tip.img
|
||||
module /Q35_SINIT_17.BIN
|
||||
|
||||
The kernel option for enabling Intel TXT support is found under the
|
||||
Security top-level menu and is called "Enable Intel(R) Trusted
|
||||
Execution Technology (TXT)". It is marked as EXPERIMENTAL and
|
||||
depends on the generic x86 support (to allow maximum flexibility in
|
||||
kernel build options), since the tboot code will detect whether the
|
||||
platform actually supports Intel TXT and thus whether any of the
|
||||
kernel code is executed.
|
||||
|
||||
The Q35_SINIT_17.BIN file is what Intel TXT refers to as an
|
||||
Authenticated Code Module. It is specific to the chipset in the
|
||||
system and can also be found on the Trusted Boot site. It is an
|
||||
(unencrypted) module signed by Intel that is used as part of the
|
||||
DRTM process to verify and configure the system. It is signed
|
||||
because it operates at a higher privilege level in the system than
|
||||
any other macrocode and its correct operation is critical to the
|
||||
establishment of the DRTM. The process for determining the correct
|
||||
SINIT ACM for a system is documented in the SINIT-guide.txt file
|
||||
that is on the tboot SourceForge site under the SINIT ACM downloads.

The Definitive KVM (Kernel-based Virtual Machine) API Documentation
|
||||
===================================================================
|
||||
|
||||
1. General description
|
||||
|
||||
The kvm API is a set of ioctls that are issued to control various aspects
|
||||
of a virtual machine. The ioctls belong to three classes
|
||||
|
||||
- System ioctls: These query and set global attributes which affect the
|
||||
whole kvm subsystem. In addition a system ioctl is used to create
|
||||
virtual machines
|
||||
|
||||
- VM ioctls: These query and set attributes that affect an entire virtual
|
||||
machine, for example memory layout. In addition a VM ioctl is used to
|
||||
create virtual cpus (vcpus).
|
||||
|
||||
Only run VM ioctls from the same process (address space) that was used
|
||||
to create the VM.
|
||||
|
||||
- vcpu ioctls: These query and set attributes that control the operation
|
||||
of a single virtual cpu.
|
||||
|
||||
Only run vcpu ioctls from the same thread that was used to create the
|
||||
vcpu.
|
||||
|
||||
2. File descritpors
|
||||
|
||||
The kvm API is centered around file descriptors. An initial
|
||||
open("/dev/kvm") obtains a handle to the kvm subsystem; this handle
|
||||
can be used to issue system ioctls. A KVM_CREATE_VM ioctl on this
|
||||
handle will create a VM file descripror which can be used to issue VM
|
||||
ioctls. A KVM_CREATE_VCPU ioctl on a VM fd will create a virtual cpu
|
||||
and return a file descriptor pointing to it. Finally, ioctls on a vcpu
|
||||
fd can be used to control the vcpu, including the important task of
|
||||
actually running guest code.
|
||||
|
||||
In general file descriptors can be migrated among processes by means
|
||||
of fork() and the SCM_RIGHTS facility of unix domain socket. These
|
||||
kinds of tricks are explicitly not supported by kvm. While they will
|
||||
not cause harm to the host, their actual behavior is not guaranteed by
|
||||
the API. The only supported use is one virtual machine per process,
|
||||
and one vcpu per thread.
|
||||
|
||||
3. Extensions
|
||||
|
||||
As of Linux 2.6.22, the KVM ABI has been stabilized: no backward
|
||||
incompatible change are allowed. However, there is an extension
|
||||
facility that allows backward-compatible extensions to the API to be
|
||||
queried and used.
|
||||
|
||||
The extension mechanism is not based on on the Linux version number.
|
||||
Instead, kvm defines extension identifiers and a facility to query
|
||||
whether a particular extension identifier is available. If it is, a
|
||||
set of ioctls is available for application use.
|
||||
|
||||
4. API description
|
||||
|
||||
This section describes ioctls that can be used to control kvm guests.
|
||||
For each ioctl, the following information is provided along with a
|
||||
description:
|
||||
|
||||
Capability: which KVM extension provides this ioctl. Can be 'basic',
|
||||
which means that is will be provided by any kernel that supports
|
||||
API version 12 (see section 4.1), or a KVM_CAP_xyz constant, which
|
||||
means availability needs to be checked with KVM_CHECK_EXTENSION
|
||||
(see section 4.4).
|
||||
|
||||
Architectures: which instruction set architectures provide this ioctl.
|
||||
x86 includes both i386 and x86_64.
|
||||
|
||||
Type: system, vm, or vcpu.
|
||||
|
||||
Parameters: what parameters are accepted by the ioctl.
|
||||
|
||||
Returns: the return value. General error numbers (EBADF, ENOMEM, EINVAL)
|
||||
are not detailed, but errors with specific meanings are.
|
||||
|
||||
4.1 KVM_GET_API_VERSION
|
||||
|
||||
Capability: basic
|
||||
Architectures: all
|
||||
Type: system ioctl
|
||||
Parameters: none
|
||||
Returns: the constant KVM_API_VERSION (=12)
|
||||
|
||||
This identifies the API version as the stable kvm API. It is not
|
||||
expected that this number will change. However, Linux 2.6.20 and
|
||||
2.6.21 report earlier versions; these are not documented and not
|
||||
supported. Applications should refuse to run if KVM_GET_API_VERSION
|
||||
returns a value other than 12. If this check passes, all ioctls
|
||||
described as 'basic' will be available.
|
||||
|
||||
4.2 KVM_CREATE_VM
|
||||
|
||||
Capability: basic
|
||||
Architectures: all
|
||||
Type: system ioctl
|
||||
Parameters: none
|
||||
Returns: a VM fd that can be used to control the new virtual machine.
|
||||
|
||||
The new VM has no virtual cpus and no memory. An mmap() of a VM fd
|
||||
will access the virtual machine's physical address space; offset zero
|
||||
corresponds to guest physical address zero. Use of mmap() on a VM fd
|
||||
is discouraged if userspace memory allocation (KVM_CAP_USER_MEMORY) is
|
||||
available.
|
||||
|
||||
4.3 KVM_GET_MSR_INDEX_LIST
|
||||
|
||||
Capability: basic
|
||||
Architectures: x86
|
||||
Type: system
|
||||
Parameters: struct kvm_msr_list (in/out)
|
||||
Returns: 0 on success; -1 on error
|
||||
Errors:
|
||||
E2BIG: the msr index list is to be to fit in the array specified by
|
||||
the user.
|
||||
|
||||
struct kvm_msr_list {
|
||||
__u32 nmsrs; /* number of msrs in entries */
|
||||
__u32 indices[0];
|
||||
};
|
||||
|
||||
This ioctl returns the guest msrs that are supported. The list varies
|
||||
by kvm version and host processor, but does not change otherwise. The
|
||||
user fills in the size of the indices array in nmsrs, and in return
|
||||
kvm adjusts nmsrs to reflect the actual number of msrs and fills in

4.4 KVM_CHECK_EXTENSION
|
||||
|
||||
Capability: basic
|
||||
Architectures: all
|
||||
Type: system ioctl
|
||||
Parameters: extension identifier (KVM_CAP_*)
|
||||
Returns: 0 if unsupported; 1 (or some other positive integer) if supported
|
||||
|
||||
The API allows the application to query about extensions to the core
|
||||
kvm API. Userspace passes an extension identifier (an integer) and
|
||||
receives an integer that describes the extension availability.
|
||||
Generally 0 means no and 1 means yes, but some extensions may report
|
||||
additional information in the integer return value.
|
||||
|
||||
4.5 KVM_GET_VCPU_MMAP_SIZE
|
||||
|
||||
Capability: basic
|
||||
Architectures: all
|
||||
Type: system ioctl
|
||||
Parameters: none
|
||||
Returns: size of vcpu mmap area, in bytes
|
||||
|
||||
The KVM_RUN ioctl (cf.) communicates with userspace via a shared
|
||||
memory region. This ioctl returns the size of that region. See the
|
||||
KVM_RUN documentation for details.
|
||||
|
||||
4.6 KVM_SET_MEMORY_REGION
|
||||
|
||||
Capability: basic
|
||||
Architectures: all
|
||||
Type: vm ioctl
|
||||
Parameters: struct kvm_memory_region (in)
|
||||
Returns: 0 on success, -1 on error
|
||||
|
||||
struct kvm_memory_region {
|
||||
__u32 slot;
|
||||
__u32 flags;
|
||||
__u64 guest_phys_addr;
|
||||
__u64 memory_size; /* bytes */
|
||||
};
|
||||
|
||||
/* for kvm_memory_region::flags */
|
||||
#define KVM_MEM_LOG_DIRTY_PAGES 1UL
|
||||
|
||||
This ioctl allows the user to create or modify a guest physical memory
|
||||
slot. When changing an existing slot, it may be moved in the guest
|
||||
physical memory space, or its flags may be modified. It may not be
|
||||
resized. Slots may not overlap.
|
||||
|
||||
The flags field supports just one flag, KVM_MEM_LOG_DIRTY_PAGES, which
|
||||
instructs kvm to keep track of writes to memory within the slot. See
|
||||
the KVM_GET_DIRTY_LOG ioctl.
|
||||
|
||||
It is recommended to use the KVM_SET_USER_MEMORY_REGION ioctl instead
|
||||
of this API, if available. This newer API allows placing guest memory
|
||||
at specified locations in the host address space, yielding better
|
||||
control and easy access.
|
||||
|
||||
4.6 KVM_CREATE_VCPU
|
||||
|
||||
Capability: basic
|
||||
Architectures: all
|
||||
Type: vm ioctl
|
||||
Parameters: vcpu id (apic id on x86)
|
||||
Returns: vcpu fd on success, -1 on error
|
||||
|
||||
This API adds a vcpu to a virtual machine. The vcpu id is a small integer
|
||||
in the range [0, max_vcpus).
|
||||
|
||||

|
||||
|
||||
/* for KVM_GET_DIRTY_LOG */
|
||||
struct kvm_dirty_log {
|
||||
__u32 slot;
|
||||
__u32 padding;
|
||||
union {
|
||||
void __user *dirty_bitmap; /* one bit per page */
|
||||
__u64 padding;
|
||||
};
|
||||
};
|
||||
|
||||
Given a memory slot, return a bitmap containing any pages dirtied
|
||||
since the last call to this ioctl. Bit 0 is the first page in the
|
||||
memory slot. Ensure the entire structure is cleared to avoid padding
|
||||
issues.
|
||||
|
||||
4.8 KVM_SET_MEMORY_ALIAS

Parameters: struct kvm_memory_alias (in)
|
||||
Returns: 0 (success), -1 (error)
|
||||
|
||||
struct kvm_memory_alias {
|
||||
__u32 slot; /* this has a different namespace than memory slots */
|
||||
__u32 flags;
|
||||
__u64 guest_phys_addr;
|

This ioctl is used to run a guest virtual cpu. While there are no
|
||||
explicit parameters, there is an implicit parameter block that can be
|
||||
obtained by mmap()ing the vcpu fd at offset 0, with the size given by
|
||||
KVM_GET_VCPU_MMAP_SIZE. The parameter block is formatted as a 'struct

|
||||
Returns: 0 on success, -1 on error
|
||||
|
||||
Sets the level of a GSI input to the interrupt controller model in the kernel.
|
||||
Requires that an interrupt controller model has been previously created with
|
||||
KVM_CREATE_IRQCHIP. Note that edge-triggered interrupts require the level
|

5. The kvm_run structure
|
||||
|
||||
Application code obtains a pointer to the kvm_run structure by
|
||||
mmap()ing a vcpu fd. From that point, application code can control
|
||||
execution by changing fields in kvm_run prior to calling the KVM_RUN
|
||||
ioctl, and obtain information about the reason KVM_RUN returned by
|
||||
looking up structure members.
|
||||
|
||||
struct kvm_run {
|
||||
/* in */
|
||||
__u8 request_interrupt_window;
|
||||
|
||||
Request that KVM_RUN return when it becomes possible to inject external
|
||||
interrupts into the guest. Useful in conjunction with KVM_INTERRUPT.
|
||||
|
||||
__u8 padding1[7];
|
||||
|
||||
/* out */
|
||||
__u32 exit_reason;
|
||||
|
||||
When KVM_RUN has returned successfully (return value 0), this informs
|
||||
application code why KVM_RUN has returned. Allowable values for this
|
||||
field are detailed below.
|
||||
|
||||
__u8 ready_for_interrupt_injection;
|
||||
|
||||
If request_interrupt_window has been specified, this field indicates
|
||||
an interrupt can be injected now with KVM_INTERRUPT.
|
||||
|
||||
__u8 if_flag;
|
||||
|
||||
The value of the current interrupt flag. Only valid if in-kernel
|
||||
local APIC is not used.
|
||||
|
||||
__u8 padding2[2];
|
||||
|
||||
/* in (pre_kvm_run), out (post_kvm_run) */
|
||||
__u64 cr8;
|
||||
|
||||
The value of the cr8 register. Only valid if in-kernel local APIC is
|
||||
not used. Both input and output.
|
||||
|
||||
__u64 apic_base;
|
||||
|
||||
The value of the APIC BASE msr. Only valid if in-kernel local
|
||||
APIC is not used. Both input and output.
|
||||
|
||||
union {
|
||||
/* KVM_EXIT_UNKNOWN */
|
||||
struct {
|
||||
__u64 hardware_exit_reason;
|
||||
} hw;
|
||||
|
||||
If exit_reason is KVM_EXIT_UNKNOWN, the vcpu has exited due to unknown
|
||||

When CONFIG_SND_HDA_PATCH_LOADER=y is set, you can pass a "patch" as a
|
||||
firmware file for modifying the HD-audio setup before initializing the
|
||||
codec. This can work basically like the reconfiguration via sysfs in
|
||||
the above, but it does it before the first codec configuration.
|
||||
|
||||
A patch file is a plain text file which looks like below:
|
||||
|
||||
------------------------------------------------------------------------
|
||||
[codec]
|
||||
0x12345678 0xabcd1234 2
|
||||
|
||||
[model]
|
||||
auto
|
||||
|
||||
[pincfg]
|
||||
0x12 0x411111f0
|
||||
|
||||
[verb]
|
||||
0x20 0x500 0x03
|
||||
0x20 0x400 0xff
|
||||
|
||||
[hint]
|
||||
hp_detect = yes
|
||||
------------------------------------------------------------------------
|
||||
|
||||
The file needs to have a line `[codec]`. The next line should contain
|
||||
three numbers indicating the codec vendor-id (0x12345678 in the
|
||||
example), the codec subsystem-id (0xabcd1234) and the address (2) of
|
||||
the codec. The rest patch entries are applied to this specified codec
|
||||
until another codec entry is given.
|
||||
|
||||
The `[model]` line allows to change the model name of the each codec.
|
||||
In the example above, it will be changed to model=auto.
|
||||
Note that this overrides the module option.
|
||||
|
||||
After the `[pincfg]` line, the contents are parsed as the initial
|
||||
default pin-configurations just like `user_pin_configs` sysfs above.
|
||||
The values can be shown in user_pin_configs sysfs file, too.
|
||||
|
||||
Similarly, the lines after `[verb]` are parsed as `init_verbs`
|
||||
sysfs entries, and the lines after `[hint]` are parsed as `hints`
|
||||
sysfs entries, respectively.
|
||||
|
||||
The hd-audio driver reads the file via request_firmware(). Thus,
|
||||
a patch file has to be located on the appropriate firmware path,
|
||||
typically, /lib/firmware. For example, when you pass the option
|
||||
`patch=hda-init.fw`, the file /lib/firmware/hda-init-fw must be
|
||||
present.
|
||||
|
||||
The patch module option is specific to each card instance, and you
|
||||
need to give one file name for each instance, separated by commas.
|
||||
For example, if you have two cards, one for an on-board analog and one
|
||||
for an HDMI video board, you may pass patch option like below:
|
||||
------------------------------------------------------------------------
|
||||
options snd-hda-intel patch=on-board-patch,hdmi-patch
|
||||
------------------------------------------------------------------------

Terminology used in this Document
|
||||
---------------------------------
|
||||
|
||||
tail - where new writes happen in the ring buffer.
|
||||
|
||||
head - where new reads happen in the ring buffer.
|
||||
|
||||
producer - the task that writes into the ring buffer (same as writer)
|
||||
|
||||
writer - same as producer
|
||||
|
||||
consumer - the task that reads from the buffer (same as reader)
|
||||
|
||||
reader - same as consumer.
|
||||
|
||||
reader_page - A page outside the ring buffer used solely (for the most part)
|
||||
by the reader.
|
||||
|
||||
head_page - a pointer to the page that the reader will use next
|
||||
|
||||
tail_page - a pointer to the page that will be written to next
|
||||
|
||||
commit_page - a pointer to the page with the last finished non nested write.
|
||||
|
||||
cmpxchg - hardware assisted atomic transaction that performs the following:
|
||||
|
||||
A = B iff previous A == C
|
||||
|
||||
R = cmpxchg(A, C, B) is saying that we replace A with B if and only if
|
||||
current A is equal to C, and we put the old (current) A into R
|
||||
|
||||
R gets the previous A regardless if A is updated with B or not.
|
||||
|
||||
To see if the update was successful a compare of R == C may be used.
|
||||
|
||||
The Generic Ring Buffer
|
||||
-----------------------
|
||||
|
||||
The ring buffer can be used in either an overwrite mode or in
|
||||
producer/consumer mode.
|
||||
|
||||
Producer/consumer mode is where the producer were to fill up the
|
||||
buffer before the consumer could free up anything, the producer
|
||||
will stop writing to the buffer. This will lose most recent events.
|
||||
|
||||
Overwrite mode is where the produce were to fill up the buffer
|
||||
before the consumer could free up anything, the producer will
|
||||
overwrite the older data. This will lose the oldest events.
|
||||
|
||||
No two writers can write at the same time (on the same per cpu buffer),
|
||||
but a writer may interrupt another writer, but it must finish writing
|
||||
before the previous writer may continue. This is very important to the
|
||||
algorithm. The writers act like a "stack". The way interrupts works
|
||||
enforces this behavior.
|
||||
|
||||
|
||||
writer1 start
|
||||
<preempted> writer2 start
|
||||
<preempted> writer3 start
|
||||
writer3 finishes
|
||||
writer2 finishes
|
||||
writer1 finishes
|
||||
|
||||
This is very much like a writer being preempted by an interrupt and
|
||||
the interrupt doing a write as well.
|
||||
|
||||
Readers can happen at any time. But no two readers may run at the
|
||||
same time, nor can a reader preempt/interrupt another reader. A reader
|
||||
can not preempt/interrupt a writer, but it may read/consume from the
|
||||
buffer at the same time as a writer is writing, but the reader must be
|
||||
on another processor to do so. A reader may read on its own processor
|
||||
and can be preempted by a writer.
|
||||
|
||||
A writer can preempt a reader, but a reader can not preempt a writer.
|
||||
But a reader can read the buffer at the same time (on another processor)
|
||||
as a writer.
|
||||
|
||||
The ring buffer is made up of a list of pages held together by a link list.
|
||||
|
||||
At initialization a reader page is allocated for the reader that is not
|
||||
part of the ring buffer.
|
||||
|
||||
The head_page, tail_page and commit_page are all initialized to point
|
||||
to the same page.
|
||||
|
||||
The reader page is initialized to have its next pointer pointing to
|
||||
the head page, and its previous pointer pointing to a page before
|
||||
the head page.
|
||||
|
||||
The reader has its own page to use. At start up time, this page is
|
||||
allocated but is not attached to the list. When the reader wants
|
||||
to read from the buffer, if its page is empty (like it is on start up)
|
||||
it will swap its page with the head_page. The old reader page will
|
||||
become part of the ring buffer and the head_page will be removed.
|
||||
The page after the inserted page (old reader_page) will become the
|
||||
new head page.
|
||||
|
||||
Once the new page is given to the reader, the reader could do what
|
||||
it wants with it, as long as a writer has left that page.
|
||||
|
||||
A sample of how the reader page is swapped: Note this does not
|
||||
show the head page in the buffer, it is for demonstrating a swap
|
||||
only.

It is possible that the page swapped is the commit page and the tail page,

if what is in the ring buffer is less than what is held in a buffer page.

|

This case is still valid for this algorithm.
|
||||
When the writer leaves the page, it simply goes into the ring buffer
|
||||
since the reader page still points to the next location in the ring
|
||||
buffer.
|
||||
|
||||
|
||||
The main pointers:
|
||||
|
||||
reader page - The page used solely by the reader and is not part
|
||||
of the ring buffer (may be swapped in)
|
||||
|
||||
head page - the next page in the ring buffer that will be swapped
|
||||
with the reader page.
|
||||
|
||||
tail page - the page where the next write will take place.
|
||||
|
||||
commit page - the page that last finished a write.
|
||||
|
||||
The commit page only is updated by the outer most writer in the
|
||||
writer stack. A writer that preempts another writer will not move the
|
||||
commit page.
|
||||
|
||||
When data is written into the ring buffer, a position is reserved
|
||||
in the ring buffer and passed back to the writer. When the writer
|
||||
is finished writing data into that position, it commits the write.
|
||||
|
||||
Another write (or a read) may take place at anytime during this
|
||||
transaction. If another write happens it must finish before continuing
|
||||
with the previous write.
|
||||
|
||||
|
||||
Write reserve:
|
||||
|
||||
Buffer page
|
||||
+---------+
|
||||
|written |
|
||||
+---------+ <--- given back to writer (current commit)

|
||||

|
||||
+---------+
|
||||
|written |
|
||||
+---------+ <--- next positon for write (current commit)
|
||||
| empty |
|
||||
+---------+
|
||||
|
||||
|
||||
If a write happens after the first reserve:
|
||||
|
||||
Buffer page
|
||||
+---------+
|
||||
|written |
|
||||
+---------+ <-- current commit
|
||||
|reserved |
|
||||
+---------+ <--- given back to second writer
|
||||
|reserved |
|
||||
+---------+ <--- tail pointer
|
||||
|
||||
After second writer commits:
|
||||
|
||||
|
||||
Buffer page
|
||||
+---------+
|
||||
|written |
|
||||
+---------+ <--(last full commit)
|
||||
|reserved |
|
||||
+---------+
|
||||
|pending |
|
||||
|commit |
|
||||
+---------+ <--- tail pointer
|
||||
|
||||
When the first writer commits:
|
||||
|
||||
Buffer page
|
||||
+---------+
|
||||
|written |
|
||||
+---------+
|
||||
|written |
|
||||
+---------+
|
||||
|written |
|
||||
+---------+ <--(last full commit and tail pointer)
|
||||
|
||||
|
||||
The commit pointer points to the last write location that was
|
||||
committed without preempting another write. When a write that
|
||||
preempted another write is committed, it only becomes a pending commit
|
||||
and will not be a full commit till all writes have been committed.
|
||||
|
||||
The commit page points to the page that has the last full commit.
|
||||
The tail page points to the page with the last write (before
|
||||
committing).
|
||||
|
||||
The tail page is always equal to or after the commit page. It may
|
||||
be several pages ahead. If the tail page catches up to the commit
|
||||
page then no more writes may take place (regardless of the mode
|
||||
of the ring buffer: overwrite and produce/consumer).
|
||||
|
||||
The order of pages are:
|
||||
|
||||
head page
|
||||
commit page
|
||||
tail page
|
||||
|
||||
Possible scenario:
|
||||
tail page
|
||||
head page commit page |
|

v v v

|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
There is a special case that the head page is after either the commit page
|
||||
and possibly the tail page. That is when the commit (and tail) page has been
|
||||
swapped with the reader page. This is because the head page is always
|
||||
part of the ring buffer, but the reader page is not. When ever there
|
||||
has been less than a full page that has been committed inside the ring buffer,
|
||||
and a reader swaps out a page, it will be swapping out the commit page.
|
||||

||||

|

^
|
||||
|
|
||||
head page
|
||||
|
||||
|
||||
In this case, the head page will not move when the tail and commit
|
||||
move back into the ring buffer.
|
||||
|
||||
The reader can not swap a page into the ring buffer if the commit page
|
||||
is still on that page. If the read meets the last commit (real commit
|
||||
not pending or reserved), then there is nothing more to read.
|
||||
The buffer is considered empty until another full commit finishes.
|
||||
|
||||
When the tail meets the head page, if the buffer is in overwrite mode,
|
||||
the head page will be pushed ahead one. If the buffer is in producer/consumer
|
||||
mode, the write will fail.
|
||||
|

|

|
|

head page
|
||||
|
||||
Note, the reader page will still point to the previous head page.
|
||||
But when a swap takes place, it will use the most recent head page.
|
||||
|
||||
|
||||
Making the Ring Buffer Lockless:
|
||||
--------------------------------
|
||||
|
||||
The main idea behind the lockless algorithm is to combine the moving
|
||||
of the head_page pointer with the swapping of pages with the reader.
|
||||
State flags are placed inside the pointer to the page. To do this,
|
||||
each page must be aligned in memory by 4 bytes. This will allow the 2
|
||||
least significant bits of the address to be used as flags. Since
|
||||
they will always be zero for the address. To get the address,
|
||||
simply mask out the flags.
|
||||
|
||||
MASK = ~3
|
||||
|
||||
address & MASK
|
||||
|
||||
Two flags will be kept by these two bits:
|
||||
|
||||
HEADER - the page being pointed to is a head page
|
||||
|
||||
UPDATE - the page being pointed to is being updated by a writer
|
||||
and was or is about to be a head page.
|
||||
|
||||
|
||||
reader page
|
||||
|
|
||||
v
|
||||
+---+
|
||||
| |------+
|
||||
+---+ |
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-H->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
|
||||
The above pointer "-H->" would have the HEADER flag set. That is
|
||||
the next page is the next page to be swapped out by the reader.
|
||||
This pointer means the next page is the head page.
|
||||
|
||||
When the tail page meets the head pointer, it will use cmpxchg to
|
||||
change the pointer to the UPDATE state:
|
||||
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-H->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
"-U->" represents a pointer in the UPDATE state.
|
||||
|
||||
Any access to the reader will need to take some sort of lock to serialize
|
||||
the readers. But the writers will never take a lock to write to the
|
||||
ring buffer. This means we only need to worry about a single reader,
|
||||
and writes only preempt in "stack" formation.
|
||||
|
||||
When the reader tries to swap the page with the ring buffer, it
|
||||
will also use cmpxchg. If the flag bit in the pointer to the
|
||||
head page does not have the HEADER flag set, the compare will fail
|
||||
and the reader will need to look for the new head page and try again.
|
||||
Note, the flag UPDATE and HEADER are never set at the same time.
|
||||
|
||||
The reader swaps the reader page as follows:
|
||||
|
||||
+------+
|
||||
|reader| RING BUFFER
|
||||
|page |
|
||||
+------+
|
||||
+---+ +---+ +---+
|
||||
| |--->| |--->| |
|
||||
| |<---| |<---| |
|
||||
+---+ +---+ +---+
|
||||
^ | ^ |
|
||||
| +---------------+ |
|
||||
+-----H-------------+
|
||||
|
||||
The reader sets the reader page next pointer as HEADER to the page after
|
||||
the head page.
|
||||
|
||||
|
||||
+------+
|
||||
|reader| RING BUFFER
|
||||
|page |-------H-----------+
|
||||
+------+ v
|
||||
| +---+ +---+ +---+
|
||||
| | |--->| |--->| |
|

|
||||
| +---+ +---+ +---+ |
|
||||
| ^ | ^ | |
|
||||
| | +---------------+ | |
|
||||
| +-----H-------------+ |
|
||||
+--------------------------------------+
|
||||
|
||||
It does a cmpxchg with the pointer to the previous head page to make it
|
||||
point to the reader page. Note that the new pointer does not have the HEADER
|
||||
flag set. This action atomically moves the head page forward.
|
||||
|
||||
+------+
|
||||
|reader| RING BUFFER
|
||||
|page |-------H-----------+
|

| | +-------------+ | |
|

| +-----------------------------+ |
|
||||
+------------------------------------+
|
||||
|
||||
After the new head page is set, the previous pointer of the head page is
|
||||
updated to the reader page.
|
||||
|
||||
+------+
|
||||
|reader| RING BUFFER

|
||||
|
||||
Another important point. The page that the reader page points back to
|
||||
by its previous pointer (the one that now points to the new head page)
|
||||
never points back to the reader page. That is because the reader page is
|
||||
not part of the ring buffer. Traversing the ring buffer via the next pointers
|
||||
will always stay in the ring buffer. Traversing the ring buffer via the
|
||||
prev pointers may not.
|
||||
|
||||
Note, the way to determine a reader page is simply by examining the previous
|
||||
pointer of the page. If the next pointer of the previous page does not
|
||||
point back to the original page, then the original page is a reader page:
|
||||
|
||||
|
||||
+--------+
|
||||
| reader | next +----+
|
||||
| page |-------->| |<====== (buffer page)
|
||||
+--------+ +----+
|
||||
| | ^
|
||||
| v | next
|
||||
prev | +----+
|
||||
+------------->| |
|
||||
+----+
|
||||
|
||||
The way the head page moves forward:
|
||||
|
||||
When the tail page meets the head page and the buffer is in overwrite mode
|
||||
and more writes take place, the head page must be moved forward before the
|
||||
writer may move the tail page. The way this is done is that the writer
|
||||
performs a cmpxchg to convert the pointer to the head page from the HEADER
|
||||
flag to have the UPDATE flag set. Once this is done, the reader will
|
||||
not be able to swap the head page from the buffer, nor will it be able to
|
||||
move the head page, until the writer is finished with the move.
|
||||
|
||||
This eliminates any races that the reader can have on the writer. The reader
|
||||
must spin, and this is why the reader can not preempt the writer.

|

+---+ +---+ +---+ +---+
|
||||
|

After the new head page has been set, we can set the old head page
|
||||
pointer back to NORMAL.
|
||||
|
||||
tail page
|

|
|

After the head page has been moved, the tail page may now move forward.

|
||||
|
||||
|
||||
The above are the trivial updates. Now for the more complex scenarios.
|
||||
|
||||
|
||||
As stated before, if enough writes preempt the first write, the
|
||||
tail page may make it all the way around the buffer and meet the commit
|
||||
page. At this time, we must start dropping writes (usually with some kind
|
||||
of warning to the user). But what happens if the commit was still on the
|
||||
reader page? The commit page is not part of the ring buffer. The tail page
|
||||
must account for this.
|
||||
|
||||

||||

|
||||
+---+ +---+ +---+ +---+
|
||||
^
|
||||
|
|
||||
tail page
|
||||
|
||||
If the tail page were to simply push the head page forward, the commit when
|
||||
leaving the reader page would not be pointing to the correct page.
|
||||
|
||||
The solution to this is to test if the commit page is on the reader page
|
||||
before pushing the head page. If it is, then it can be assumed that the
|
||||
tail page wrapped the buffer, and we must drop new writes.
|
||||
|
||||
This is not a race condition, because the commit page can only be moved
|
||||
by the outter most writer (the writer that was preempted).
|
||||
This means that the commit will not move while a writer is moving the
|
||||
tail page. The reader can not swap the reader page if it is also being
|
||||
used as the commit page. The reader can simply check that the commit
|
||||
is off the reader page. Once the commit page leaves the reader page
|
||||
it will never go back on it unless a reader does another swap with the
|
||||
buffer page that is also the commit page.
|
||||
|
||||
|
||||
Nested writes
|
||||
-------------
|
||||
|
||||
In the pushing forward of the tail page we must first push forward
|
||||
the head page if the head page is the next page. If the head page
|
||||
is not the next page, the tail page is simply updated with a cmpxchg.
|
||||
|
||||
Only writers move the tail page. This must be done atomically to protect
|
||||
against nested writers.
|
||||
|
||||
temp_page = tail_page
|
||||
next_page = temp_page->next
|
||||
cmpxchg(tail_page, temp_page, next_page)
|
||||
|
||||
The above will update the tail page if it is still pointing to the expected
|
||||
page. If this fails, a nested write pushed it forward, the the current write
|
||||
does not need to push it.
|
||||
|
||||
|
||||
temp page
|
||||
|
|
||||

|
||||
tail page
|
||||

+---+ +---+ +---+ +---+

||||
<---| |--->| |--->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
Nested write comes in and moves the tail page forward:
|
||||
|
||||
tail page (moved by nested writer)
|
||||
temp page |
|
||||
| |
|
||||
v v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |--->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
The above would fail the cmpxchg, but since the tail page has already
|
||||
been moved forward, the writer will just try again to reserve storage
|
||||
on the new tail page.
|
||||
|
||||
But the moving of the head page is a bit more complex.
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-H->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
The write converts the head page pointer to UPDATE.
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
But if a nested writer preempts here. It will see that the next
|
||||
page is a head page, but it is also nested. It will detect that
|
||||
it is nested and will save that information. The detection is the
|
||||
fact that it sees the UPDATE flag instead of a HEADER or NORMAL
|
||||
pointer.
|
||||
|
||||
The nested writer will set the new head page pointer.
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-H->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
But it will not reset the update back to normal. Only the writer
|
||||
that converted a pointer from HEAD to UPDATE will convert it back
|
||||
to NORMAL.
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-H->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
After the nested writer finishes, the outer most writer will convert
|
||||
the UPDATE pointer to NORMAL.
|
||||
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |--->| |-H->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
|
||||
It can be even more complex if several nested writes came in and moved
|
||||
the tail page ahead several pages:
|
||||
|
||||
|
||||
(first writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-H->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
The write converts the head page pointer to UPDATE.
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |--->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
Next writer comes in, and sees the update and sets up the new
|
||||
head page.
|
||||
|
||||
(second writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-H->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
The nested writer moves the tail page forward. But does not set the old
|
||||
update page to NORMAL because it is not the outer most writer.
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-H->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
Another writer preempts and sees the page after the tail page is a head page.
|
||||
It changes it from HEAD to UPDATE.
|
||||
|
||||
(third writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-U->| |--->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
The writer will move the head page forward:
|
||||
|
||||
|
||||
(third writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-U->| |-H->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
But now that the third writer did change the HEAD flag to UPDATE it
|
||||
will convert it to normal:
|
||||
|
||||
|
||||
(third writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |--->| |-H->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
|
||||
Then it will move the tail page, and return back to the second writer.
|
||||
|
||||
|
||||
(second writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |--->| |-H->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
|
||||
The second writer will fail to move the tail page because it was already
|
||||
moved, so it will try again and add its data to the new tail page.
|
||||
It will return to the first writer.
|
||||
|
||||
|
||||
(first writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |--->| |-H->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
The first writer can not know atomically test if the tail page moved
|
||||
while it updates the HEAD page. It will then update the head page to
|
||||
what it thinks is the new head page.
|
||||
|
||||
|
||||
(first writer)
|
||||
|
||||
tail page
|
||||
|
|
||||
v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-H->| |-H->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
Since the cmpxchg returns the old value of the pointer the first writer
|
||||
will see it succeeded in updating the pointer from NORMAL to HEAD.
|
||||
But as we can see, this is not good enough. It must also check to see
|
||||
if the tail page is either where it use to be or on the next page:
|
||||
|
||||
|
||||
(first writer)
|
||||
|
||||
A B tail page
|
||||
| | |
|
||||
v v v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |-H->| |-H->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
If tail page != A and tail page does not equal B, then it must reset the
|
||||
pointer back to NORMAL. The fact that it only needs to worry about
|
||||
nested writers, it only needs to check this after setting the HEAD page.
|
||||
|
||||
|
||||
(first writer)
|
||||
|
||||
A B tail page
|
||||
| | |
|
||||
v v v
|
||||
+---+ +---+ +---+ +---+
|
||||
<---| |--->| |-U->| |--->| |-H->
|
||||
--->| |<---| |<---| |<---| |<---
|
||||
+---+ +---+ +---+ +---+
|
||||
|
||||
Now the writer can update the head page. This is also why the head page must
|
||||
remain in UPDATE and only reset by the outer most writer. This prevents
|
||||
the reader from seeing the incorrect head page.
|
||||
|
||||
|
||||
(first writer)
|
||||
|
||||
A B tail page

Driver for I2C radios for the Silicon Labs Si4713 FM Radio Transmitters
|
||||
|
||||
Copyright (c) 2009 Nokia Corporation

||||
|
||||
|
||||
Information about the Device
|
||||
============================
|
||||
This chip is a Silicon Labs product. It is a I2C device, currently on 0x63 address.
|
||||
Basically, it has transmission and signal noise level measurement features.
|
||||
|
||||
The Si4713 integrates transmit functions for FM broadcast stereo transmission.
|
||||
The chip also allows integrated receive power scanning to identify low signal
|
||||
power FM channels.
|
||||
|
||||
The chip is programmed using commands and responses. There are also several
|
||||
properties which can change the behavior of this chip.
|
||||
|
||||
Users must comply with local regulations on radio frequency (RF) transmission.
|
||||
|
||||
Device driver description
|
||||
=========================
|
||||
There are two modules to handle this device. One is a I2C device driver
|
||||
and the other is a platform driver.
|
||||
|
||||
The I2C device driver exports a v4l2-subdev interface to the kernel.
|
||||
All properties can also be accessed by v4l2 extended controls interface, by
|
||||
using the v4l2-subdev calls (g_ext_ctrls, s_ext_ctrls).
|
||||
|
||||
The platform device driver exports a v4l2 radio device interface to user land.
|
||||
So, it uses the I2C device driver as a sub device in order to send the user
|
||||
commands to the actual device. Basically it is a wrapper to the I2C device driver.
|
||||
|
||||
Applications can use v4l2 radio API to specify frequency of operation, mute state,
|
||||
etc. But mostly of its properties will be present in the extended controls.
|
||||
|
||||
When the v4l2 mute property is set to 1 (true), the driver will turn the chip off.
|
||||
|
||||
Properties description
|
||||
======================
|
||||
|
||||
The properties can be accessed using v4l2 extended controls.
|
||||
Here is an output from v4l2-ctl util:
|

Here is a summary of them:
|
||||
|
||||
* Pilot is an audible tone sent by the device.
|
||||
|
||||
pilot_frequency - Configures the frequency of the stereo pilot tone.
|
||||
pilot_deviation - Configures pilot tone frequency deviation level.
|
||||
pilot_enabled - Enables or disables the pilot tone feature.
|
||||
|
||||
* The si4713 device is capable of applying audio compression to the transmitted signal.
|
||||
|
||||
acomp_enabled - Enables or disables the audio dynamic range control feature.
|
||||
acomp_gain - Sets the gain for audio dynamic range control.
|
||||
acomp_threshold - Sets the threshold level for audio dynamic range control.
|
||||
acomp_attack_time - Sets the attack time for audio dynamic range control.
|
||||
acomp_release_time - Sets the release time for audio dynamic range control.
|
||||
|
||||
* Limiter setups audio deviation limiter feature. Once a over deviation occurs,
|
||||
it is possible to adjust the front-end gain of the audio input and always
|
||||
prevent over deviation.
|
||||
|
||||
limiter_enabled - Enables or disables the limiter feature.
|
||||
limiter_deviation - Configures audio frequency deviation level.
|
||||
limiter_release_time - Sets the limiter release time.
|
||||
|
||||
* Tuning power
|
||||
|
||||
power_level - Sets the output power level for signal transmission.
|
||||
antenna_capacitor - This selects the value of antenna tuning capacitor manually
|
||||
or automatically if set to zero.
|
||||
|
||||
* RDS related
|
||||
|
||||
rds_ps_name - Sets the RDS ps name field for transmission.
|
||||
rds_radio_text - Sets the RDS radio text for transmission.
|
||||
rds_pi - Sets the RDS PI field for transmission.
|
||||
rds_pty - Sets the RDS PTY field for transmission.
|
||||
|
||||
* Region related
|
||||
|
||||
preemphasis - sets the preemphasis to be applied for transmission.
|
||||
|
||||
RNL
|
||||
===
|
||||
|
||||
This device also has an interface to measure received noise level. To do that, you should
|
||||
ioctl the device node. Here is an code of example:
|
||||
|
||||
int main (int argc, char *argv[])
|
||||
{
|
||||
struct si4713_rnl rnl;
|
||||
int fd = open("/dev/radio0", O_RDWR);
|
||||
int rval;
|
||||
|
||||
if (argc < 2)
|
||||
return -EINVAL;
|
||||
|
||||
if (fd < 0)
|
||||
return fd;
|
||||
|
||||
sscanf(argv[1], "%d", &rnl.frequency);
|
||||
|
||||
rval = ioctl(fd, SI4713_IOC_MEASURE_RNL, &rnl);
|
||||
if (rval < 0)
|
||||
return rval;
|
||||
|
||||
printf("received noise level: %d\n", rnl.rnl);
|
||||
|
||||
close(fd);
|
||||
}
|
||||
|
||||
The struct si4713_rnl and SI4713_IOC_MEASURE_RNL are defined under
|
||||
include/media/si4713.h.
|
||||
|
||||
Stereo/Mono and RDS subchannels
|
||||
===============================
|
||||
|
||||
The device can also be configured using the available sub channels for
|
||||
transmission. To do that use S/G_MODULATOR ioctl and configure txsubchans properly.
|
||||
Refer to v4l2-spec for proper use of this ioctl.
|
||||
|
||||
Testing
|
||||
=======
|
||||
Testing is usually done with v4l2-ctl utility for managing FM tuner cards.
|
||||
The tool can be found in v4l-dvb repository under v4l2-apps/util directory.
|
||||
|
||||
Example for setting rds ps name:
|
||||
# v4l2-ctl -d /dev/radio0 --set-ctrl=rds_ps_name="Dummy"

Debugging options may require the minimum possible slab order to increase as

a result of storing the metadata (for example, caches with PAGE_SIZE object

sizes). This has a higher liklihood of resulting in slab allocation errors
