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 [1] https://lwn.net/Articles/379903/ Signed-off-by: Gustavo Sousa <gustavo.sousa@xxxxxxxxx> --- .../drm/i915/display/intel_display_trace.h | 126 +++++++++--------- 1 file changed, 63 insertions(+), 63 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display_trace.h b/drivers/gpu/drm/i915/display/intel_display_trace.h index 8a3185862089..ec2ab6fb743d 100644 --- a/drivers/gpu/drm/i915/display/intel_display_trace.h +++ b/drivers/gpu/drm/i915/display/intel_display_trace.h @@ -30,7 +30,7 @@ TRACE_EVENT(intel_pipe_enable, __string(dev, __dev_name_kms(crtc)) __array(u32, frame, I915_MAX_PIPES) __array(u32, scanline, I915_MAX_PIPES) - __field(enum pipe, pipe) + __field(char, pipe_name) ), TP_fast_assign( struct drm_i915_private *dev_priv = to_i915(crtc->base.dev);
