tracing/drm: Remove unused TRACE_SYSTEM_STRING define

2015-04-07T16:29:23+00:00

The tracing infrastructure is adding a macro TRACE_SYSTEM_STRING, and hit the following build failure: In file included from include/trace/define_trace.h:90:0, from drivers/gpu/drm/.//radeon/radeon_trace.h:209, from drivers/gpu/drm/.//radeon/radeon_trace_points.c:9: >> include/trace/ftrace.h:28:0: warning: "TRACE_SYSTEM_STRING" redefined #define TRACE_SYSTEM_STRING __app(TRACE_SYSTEM_VAR,__trace_system_name) Seems that the DRM folks have added their own use to the TRACE_SYSTEM_STRING, with: #define TRACE_SYSTEM_STRING __stringify(TRACE_SYSTEM) Although, I can not find its use anywhere. I could simply use another name, but if this macro is not being used, it should be removed.

seq of a trace point is unsigned int but print format was %d. So it fixes the format as %u. Signed-off-by: Seung-Woo Kim Signed-off-by: Kyungmin Park Reviewed-by: Chris Wilson Signed-off-by: Dave Airlie

drm: add vblank event trace point

Emit a trace point for vblank events. This can be helpful for mapping drawing activity against the vblank frequency and period. Signed-off-by: Jesse Barnes Signed-off-by: Dave Airlie
