We need to generate the splash screens separately for each device,
because they are specific to the device's display resolution.
At the moment we do this dynamically during the installation process.
This has the advantage that there is no need to re-build all device
packages when one of the splash screen is changed (or a new one is added).
In reality, however, the splash screens do not change very frequently.
On the other hand, generating the splash screens dynamically has signficant
disk usage overhead for a minimal ("none" UI) rootfs:
The Python interpreter together with the necessary libraries requires
about ~60 MB of disk space on aarch64.
The splash screens itself require about ~100 KB for 720x1280.
This is not necessary if we move the splash screen generation into
devicepkg-dev, which is used to build the device package for all devices.
Another advantage is that we no longer need the (rather complicated)
caching mechanism for splash screens - so we actually end up with less
lines than before.
rootfs size for samsung-a5ulte ("none" UI):
Before: 450M
After: 388M (-62M)
After this change, every(!) device package needs to be rebuilt once.
No changes are necessary in device packages.
Kernel subpackages may contain a "-" (e.g. -kernel-mainline-modem);
replace it with an underscore to make sure that we find the
kernel-specific variables in deviceinfo.
If (a) the kernel command line parameters include PMOS_BOOTCHART2 and
(b) /sbin/bootchartd exists (i.e., the bootchart2 package has been
installed), run /sbin/bootchartd instead of /sbin/init.
Port bootchart2 to PostmarketOS, with three patches:
1. Modification of /etc/bootchartd.conf so that the collector
will stop after sshd has started.
2. Python 3.8 compatibility
3. Disable the interactive mode of pybootchartgui.
Use bootchart2 to profile system boot or a running system.
1. Add the bootchart2 package to your device.
2. Add the following kernel command line parameters: initcall_debug
printk.time=y quiet
3. To profile system boot
a. add the following kernel command line parameter: PMOS_BOOTCHART2.
This parameter causes mkinitfs to start /sbin/bootchartd instead of
/sbin/init. /sbin/bootchartd then starts /sbin/init.
b. (optional) modify EXIT_PROC in /etc/bootchartd.conf to define
when the collector is to stop.
c. Boot the system. Approximately 20 seconds after sshd starts
(if using the default value of EXIT_PROC), the collector
will exit.
4. To profile a running system
a. use the command '/sbin/bootchartd start' (as root) to start
profiling
b. use the command '/sbin/bootchartd stop' (as root) to stop
profiling
5. When the collector exits, /usr/bin/pybootchartgui will create
a visualization in /var/log/bootchart.png.
- Update to Linux 5.5-rc4
- Fix freeze/crash when accessing reserved memory on Samsung devices
- This happened e.g. when doing large eMMC writes
because the disk cache filled all available RAM.
- Fix SD card detection on samsung-serranovelte
- Disable UHS-1 modes since they appear to be broken in hardware

Comment out the initstepslew line in /etc/chrony/chrony.conf.
initstepslew can delay booting while chrony sets the time. The
makestep 1 -1 line in the configuration also causes chrony to step
the time (whenever the offset is greater than 1s), making
initstepslew redundant.
Unfortunately, early firmware versions on MSM8916 (used together with
Android 4.4) are not capable of booting aarch64 kernels. MSM8916 was
Qualcomm's first 64-bit capable CPU, and back when it was introduced
Android did not even support aarch64 yet. So the aarch64 capable
hardware was usually used together with armv7 binaries.
To make things worse, this firmware is also signed (usually per-device),
making it (currently) impossible to update it without help from the manufacturer.
This means that we are currently unable to run mainline on devices
that never received an update to Android 5.0
(e.g. the Samsung Galaxy S4 Mini Value Edition).
One way to circumvent this limitation is to build mainline for armv7.
This works surprisingly well with some additional fixes.
Devices with this firmware limitation are still unable to use aarch64
binaries, but at least we can run mainline on them!
- Rebase on Linux 5.5-rc3
- Add display, touchscreen and GPIO keys for samsung-gt510wifi
- Add vibrator for wileyfox-crackling
- Zinitix touchscreen improvements (used in samsung-a3ulte)
- Upstreamed several patches
Current default is performance, and that is for sure not a great choice
for battery. We can experiment with ondemand as well, but based on docs,
conservative is recommended.

On some devices a getty should run on the serial console.
Configure the getty by setting the deviceinfo_getty variable. The
format is "<port>;<baud rate>". For example, "ttyS0;115200".
A post-installation trigger in postmarketos-base checks
/etc/deviceinfo, and modifies /etc/inittab if the device should run
a getty.

It seems the the CFLAGS are not properly set in the CMakeLists.txt.
Cmake currently appends -std=gnu90 at the end of the CFLAGS, overriding
the earlier set -std=c99. Work around this with sed. Better fix is
welcome, this is a stop-gap solution to unbreak the build (which is
blocking build.postmarketos.org).
It's unmaintained both on our side and upstream. Nobody stepped up to
maintain it (https://gitlab.com/postmarketOS/pmaports/issues/372), so
let's drop it before it introduces security issues and compilation
problems.
ConfigFS USB attrs are customizable based on the `deviceinfo_usb_*` variables,
however some downstream kernels (e.g: msm-3.18) doesn't use configfs, instead
uses the traditional Android USB Gadget.
Based on `deviceinfo_usb_{idVendor/idProduct}` variables, we can change the USB
vendor and product.
So that on these devices, we can make it appear on USB bus as the correct USB
vendor/product ID, not "Google Inc. Nexus 4 (fastboot)"

At the moment, a full file system check is forced even if the
file system is marked clean (i.e. it was properly unmounted the
last time it was used). On large file systems with slow I/O
(e.g. SD cards), this can take a significant amount of time.
Removing the -f option of e2fsck allows skipping the full
file system check if it is marked clean, speeding up the boot time.
Some devices' downstream kernels may have different RNDIS/functionfs
drivers (ex. QCRNDIS) that require different values for some
configfs gadget attributes. Make it possible to customize with
deviceinfo file from device- package.
The idea is that each device- package can optionally specify a
bunch of `deviceinfo_usb_*` variables to customize the way it is
visible on USB bus. The ability to override
`deviceinfo_usb_rndis_function` is essential to make downstream
sdm660 based device to appear on USB bus.
While at it, make `idVendor`, `idProduct` and `serialnumber` also
customizable. So that we can make, for example, PineTab appear on
USB bus as PineTab, not as "Google Inc. Nexus 4 (fastboot)".
Mainline U-Boot looks for the device tree blob in the "second" area
of the Android boot image (see https://patchwork.ozlabs.org/patch/1025211/).
Add an option "deviceinfo_bootimg_dtb_second" to place the device DTB there.
Currently, the USB networking setup using configfs does not configure
a "serialnumber" for the USB gadget. This means that an empty
serial number will be sent during USB enumeration.
This is usually not a problem, but it seems to cause issues under
special circumstances (on asus-me176c on one of my PCs).
The USB Gadget configfs documentation also suggests setting
the "serialnumber":
https://www.kernel.org/doc/Documentation/usb/gadget_configfs.txt
It can be any string, so we can just set it as "postmarketOS" like
the manufacturer.
The openrc service of lightdm has been moved to lightdm-openrc in
Alpine. Fix all UIs depending on lightdm, so their post-install script
does not fail with:

Upgrade and add depends to static libraries to make it build again. When
the package was added initially, the static libraries were part of the
respective -dev packages.
The initramfs needs ext4 (to mount the rootfs) and usb_f_rndis
(to enable USB networking on devices that use USB configfs).
If these are built as modules, they need to be included in initramfs.

This is built when a optional dependency of qt5 widgets and qt5 network

current version merged was missing the zlib-dev and libpng-dev
dependency which would make apitrace build internal copies of them, and

The package was added with the initial Unity 8 packaging but even then
it seems that this package was never actually used.
Remove it because it no longer builds (some patches upstream might get
