Making the drm_crtc.c code recognize the DPMS property and invoke the
connector->dpms function doesn't remove any capability from the driver while
reducing code duplication.
That just highlighted the problem with the existing DPMS functions which
could turn off the connector, but failed to turn off any relevant crtcs. The
new drm_helper_connector_dpms function manages all of that, using the
drm_helper-specific crtc and encoder dpms functions, automatically computing
the appropriate DPMS level for each object in the system.
This fixes the current troubles in the i915 driver which left PLLs, pipes
and planes running while in DPMS_OFF mode or even while they were unused.

Especially with Sandisk SDHC cards, the second SWITCH command was failing
with a timeout and the card was not recognized at all. However if the
system was busy, or debugging was enabled, or a udelay(100) was inserted
before the second SWITCH command in the core code, then the timing was
so that the card started to work.
With some unusual block sizes, the data FIFO status doesn't indicate a
"empty" state right away when the data transfer is done. Queuing
another data transfer in that condition results in a transfer timeout.
The empty FIFO bit eventually get set by itself in less than 50 usecs
when it is not set right away. So let's just poll for that bit before
configuring the controller with a new data transfer.

The current method of printing out a stack trace is to add a new line

yum-updatesd-3120 [002] 573.691303:

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:

According to "events/ftrace/kernel_stack/format", output format of
kernel stack should use "=>" instead of "<=".
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

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

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.

Since we can (and do) change comm strings during the collection

Therefore add an (optional) third sorting phase to collapse the

Comm sorting now builds the histrogram on threads and then in
the collapse phase collects all threads with the same comm.
This collapsed histogram is then reversed and sorted on events.
