[PATCH v2 0/5] Miscelaneous fixes for display tracepoints

[Gustavo Sousa]

I recently bumped into some issues while using trace-cmd to inspect i915
display trace events. This series of patches provides fixes for them.

v2:
  - Add another patch to zero-initialize frame/scanline counts.
  - Add static_assert(PIPE_A == _TRACE_PIPE_A) in "Do not use ids from enum pipe
    in TP_printk()".

Gustavo Sousa (5):
  drm/i915/display: Fix out-of-bounds access in pipe-related tracepoints
  drm/i915/display: Zero-initialize frame/scanline counts in tracepoints
  drm/i915/display: Store pipe name in trace events
  drm/i915/display: Do not use ids from enum pipe in TP_printk()
  drm/i915/display: Cover all possible pipes in TP_printk()

[PATCH v2 1/5] drm/i915/display: Fix out-of-bounds access in pipe-related tracepoints

[Gustavo Sousa]

Some display trace events use array members to store frame and scanline
counts for each pipe. However, those arrays are declared with 3 as the
hardcoded size, which cause out-of-bounds access when the trace event is
enabled on a platform that contains pipe D.

For example, when looking at the last 10 intel_pipe_enable events after
running IGT's testdisplay, we see the following on a MTL machine that
has pipe D available:

    $ trace-cmd report -R -F intel_pipe_enable \
    > | tail \
    > | sed 's,\(frame=.*\) \(scanline=.*\),\n\t   \1\n\t\2,'

Which shows zeros for pipe A's scanline counts. That happens because
pipe D's frame counts are overwriting them.

Let's fix that by making the arrays bring able to store info for all
possible pipes.

With the fix, we get the following:

    $ trace-cmd report -R -F intel_pipe_enable \
    > | tail \
    > | sed 's,\(frame=.*\) \(scanline=.*\),\n\t   \1\n\t\2,'

Which makes more sense now.

[PATCH v2 2/5] drm/i915/display: Zero-initialize frame/scanline counts in tracepoints

[Gustavo Sousa]

In an upcoming change, we will also add support for logging
frame/scanline counts for pipe D in relevant tracepoints.

In [1], Matt mentioned the possibility of having garbage in those counts
for pipe D on a platform containing only 3 pipes. Indeed, it has been
verified that the counts for the extra pipe would not be
zero-initialized by the tracing system.

Since it is also possible that the same would happen for a fused-off
pipe, let's go ahead and add the logic to zero-initialize the arrays
now.

[PATCH v2 3/5] drm/i915/display: Store pipe name in trace events

[Gustavo Sousa]

The first part[1] of the LWN series on using TRACE_EVENT() mentions
about TP_printk():

    "Do not create new tracepoint-specific helpers, because that will
    confuse user-space tools that know about the TRACE_EVENT() helper
    macros but will not know how to handle ones created for individual
    tracepoints."

It seems this is what we ended up doing when using pipe_name() in
TP_printk().

For example, the format for the intel_pipe_update_start event is as
follows:

    # cat /sys/kernel/debug/tracing/events/i915/intel_pipe_update_start/format
    name: intel_pipe_update_start
    ID: 1136
    format:
            field:unsigned short common_type;       offset:0;       size:2; signed:0;
            field:unsigned char common_flags;       offset:2;       size:1; signed:0;
            field:unsigned char common_preempt_count;       offset:3;       size:1; signed:0;
            field:int common_pid;   offset:4;       size:4; signed:1;

            field:__data_loc char[] dev;    offset:8;       size:4; signed:0;
            field:enum pipe pipe;   offset:12;      size:4; signed:1;
            field:u32 frame;        offset:16;      size:4; signed:0;
            field:u32 scanline;     offset:20;      size:4; signed:0;
            field:u32 min;  offset:24;      size:4; signed:0;
            field:u32 max;  offset:28;      size:4; signed:0;

    print fmt: "dev %s, pipe %c, frame=%u, scanline=%u, min=%u, max=%u", __get_str(dev), ((REC->pipe) + 'A'), REC->frame, REC->scanline, REC->min, REC->max

The call to pipe_name(__entry->pipe) is expanted to ((REC->pipe) + 'A')
and that's how the format is saved.

Even though the output from /sys/kernel/debug/tracing/trace will look
correct (because it is generated in the kernel), we will see corrupted
lines when using a tool like trace-cmd to view the data.

While the output looks correct when looking at
/sys/kernel/debug/tracing/trace, we see corrupted lines when viewing the
trace data with "trace-cmd report":

    $ trace-cmd report \
    > | sed -n 's/.*dev 0000:00:02\.0, \(pipe .\).*/\1/p' \
    > | cat -v | uniq -c
         34 pipe ^A

, where ^A is a non-printable character.

As a fix, let's store the pipe name directly in the event. The fix was
done by applying the following sed script:

    s/__field\s*(\s*enum\s\+pipe\s*,\s*pipe\s*)/__field(char, pipe_name)/
    s/__entry\s*->\s*pipe\s*=\s*\([^;]\+\);/__entry->pipe_name = pipe_name(\1);/
    s/pipe_name\s*(\s*__entry\s*->\s*pipe\s*)/__entry->pipe_name/

After these changes, using the same example, we have the following:

    $ trace-cmd report \
    > | sed -n 's/.*dev 0000:00:02\.0, \(pipe .\).*/\1/p' \
    > | cat -v | sort | uniq -c
        396 pipe A
         34 pipe B

[PATCH v2 4/5] drm/i915/display: Do not use ids from enum pipe in TP_printk()

[Gustavo Sousa]

Because much of kernel tracepoints is implemented at the C preprocessor
level, C identifiers used in TP_printk() are saved verbatim in the event
format, even when they represent compile-time constant values.

As an example, we can look at the format for the intel_pipe_enable
event:

    # cat /sys/kernel/debug/tracing/events/i915/intel_pipe_enable/format | grep '^print fmt'
    print fmt: "dev %s, pipe %c enable, pipe A: frame=%u, scanline=%u, pipe B: frame=%u, scanline=%u, pipe C: frame=%u, scanline=%u", __get_str(dev), REC->pipe_name, REC->frame[PIPE_A], REC->scanline[PIPE_A], REC->frame[PIPE_B], REC->scanline[PIPE_B], REC->frame[PIPE_C], REC->scanline[PIPE_C]

We see that PIPE_A, PIPE_B and PIPE_C are pasted directly in the format.
Because tools that interact with kernel tracepoints don't know about
those ids, they'll endup failing to parse the format or produce
corrupted output.

For example, we can see below that trace-cmd repeats PIPE_A's
frame/scanline counts for all pipes (probably because it evaluates
unknown ids as zero):

   $ trace-cmd report -F intel_pipe_enable | tail -n5
        testdisplay-8616  [000] 22048.276758: intel_pipe_enable:    dev 0000:00:02.0, pipe A enable, pipe A: frame=861, scanline=480, pipe B: frame=861, scanline=480, pipe C: frame=861, scanline=480
        testdisplay-8616  [001] 22048.490287: intel_pipe_enable:    dev 0000:00:02.0, pipe A enable, pipe A: frame=867, scanline=480, pipe B: frame=867, scanline=480, pipe C: frame=867, scanline=480
        testdisplay-8616  [003] 22048.700181: intel_pipe_enable:    dev 0000:00:02.0, pipe A enable, pipe A: frame=872, scanline=400, pipe B: frame=872, scanline=400, pipe C: frame=872, scanline=400
        testdisplay-8616  [002] 22049.054220: intel_pipe_enable:    dev 0000:00:02.0, pipe A enable, pipe A: frame=881, scanline=2170, pipe B: frame=881, scanline=2170, pipe C: frame=881, scanline=2170

, while in fact we have different values for each pipe, which can be
confirmed with the raw view of the events:

    $ trace-cmd report -R -F intel_pipe_enable | tail -n5
         testdisplay-8616  [000] 22048.276758: intel_pipe_enable:     dev=0000:00:02.0 frame=ARRAY[5d, 03, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00] scanline=ARRAY[e0, 01, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00] pipe_name=A

         testdisplay-8616  [002] 22049.166851: intel_pipe_enable:     dev=0000:00:02.0 frame=ARRAY[77, 03, 00, 00, 01, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00] scanline=ARRAY[60, 06, 00, 00, 39, 04, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00] pipe_name=B

To fix that, we need a fix that looks more like a hack: use macros that
result to integer constants instead of enum pipe values. This fixes the
issue, but could break if, for whatever unlikely reason, the underlying
values in the enum are changed.

In the future, we should find a better way to handle this, but for now,
the hack took care of the job:

    $ trace-cmd report -F intel_pipe_enable | tail -n5

[PATCH v2 5/5] drm/i915/display: Cover all possible pipes in TP_printk()

[Gustavo Sousa]

Tracepoints that display frame and scanline counters for all pipes were
added with commit 1489bba82433 ("drm/i915: Add cxsr toggle tracepoint")
and commit 0b2599a43ca9 ("drm/i915: Add pipe enable/disable
tracepoints"). At that time, we only had pipes A, B and C. Now that we
can also have pipe D, the TP_printk() calls are missing it.

As a quick and dirty fix for that, let's define two common macros to be
used for the format and values respectively, and also ensure we raise a
build bug if more pipes are added to enum pipe.

In the future, we should probably have a way of printing information for
available pipes only.

Hmm. We have a lot of tracpoints that just print these for a single
pipe. Is there any decent way to make this macro just for one pipe,
and then resuse it for all the tracepoints whether they trace one
pipe or all of them?

Maybe what we could do is to have a local struct pipe_counters type
and have _PIPE_COUNTERS_FMT and _PIPE_COUNTERS_VALUES for it. Then they
could be used here as well as for the single-pipe cases.

Can we use structs here or would that confuse trace-cmd as well?
