I have a TrendNet 652-BRP running OpenWRT + ath9k very well. The only
problem is that the beacon gets stuck maybe once a day. After
Vasanthakumar Thiagarajan's "ath9k: cleanup beacon parameters
configuration" patch, ath9k would nearly re-configure the beacons after it
detected the stuck beacon, and did a reset. But it would fail the
SC_OP_TSF_RESET check in ath_beacon_config_ap. This patch gets the beacon
fully reconfigured after the reset.

The current method of printing out a stack trace is to add a new line
and print out the trace:
yum-updatesd-3120 [002] 573.691303:
=> do_softirq
=> irq_exit
=> smp_apic_timer_interrupt

This looks a bit awkward, and if we have both stack and user stack traces
running, it would be nice to have a title to tell them apart, although
it is easy to tell by the output.
This patch adds an annotation to the start of the stack traces:

The second problem is that we shouldn't skip the first entry in the stack,
although it seems to be duplicated when used in the "function" tracer,
but events also use it. If we skip the first one, we will drop the topmost
entry of the stack.
The last problem is that if the last entry is ULONG_MAX(0xffffffff), we should

So when printing the header, we should decrease it by one.

Depth Size Location (53 entries) <--- should be 52

Every buffer page in the ring buffer includes its own time stamp.
When an event is recorded to the ring buffer with a delta time greater
than what can be held in the event header, a time stamp event is created.
If the the create timestamp falls over to the next buffer page, it is
redundant because the buffer page holds a full time stamp. This patch
will try to discard the time stamp when it falls to the start of the
next page.
This change also fixes a issues with disarding events. If most events are
discarded, timestamps will start to creep into the ring buffer. If we
do not discard the timestamps then they can fill up the ring buffer over
time and waste space.
This change will keep time stamps from filling up over another page. If
something is recorded in the buffer page, and the rest is filtered, then
the time stamps can only fill up to the end of the page.

There are times that a race may happen that we add a timestamp in a
nested write. This timestamp would just contain a zero delta and serves
no purpose.

the timestamp instead of just wasting the space in the ring buffer.

There's a bug in ring_buffer_discard_commit. The wrong
pointer is being compared in order to check if the event
can be freed from the buffer rather than discarded
(i.e. marked as PAD).
I noticed this when I was working on duration filtering.
The bug is not deadly - it just results in lots of wasted
space in the buffer. All filtered events are left in
the buffer and marked as discarded, rather than being
removed from the buffer to make space for other events.
Unfortunately, when I fixed this bug, I got errors doing a
filtered function trace. Multiple TIME_EXTEND
events pile up in the buffer, and trigger the
following loop overage warning in rb_iter_peek():
again:
...
if (RB_WARN_ON(cpu_buffer, ++nr_loops > 10))
return NULL;
I'm not sure what the best way is to fix this. I don't
know if I should extend the loop threshhold, or if I should
make the test more complex (ignore TIME_EXTEND
events), or just get rid of this loop check completely.
Note that if I implement a workaround for this, then I
see another problem from rb_advance_iter(). I haven't
tracked that one down yet.
In general, it seems like the case of removing filtered
events has not been working properly, and so some assumptions
about buffer invariant conditions need to be revisited.
Here's the patch for the simple fix:
Compare correct pointer for checking if an event can be
freed rather than left as discarded in the buffer.

The UV tlb shootdown code has a serious initialization error.
An array of structures [32*8] is initialized as if it were [32].
The array is indexed by (cpu number on the blade)*8, so the short
initialization works for up to 4 cpus on a blade.
But above that, we provide an invalid opcode to the hub's
broadcast assist unit.
This patch changes the allocation of the array to use its symbolic
dimensions for better clarity. And initializes all 32*8 entries.
