    drm/i915/tracepoints: Add request submit and execute tracepoints · 354d036f
    Tvrtko Ursulin authored
    These new tracepoints are emitted once the request is ready to
    be submitted to the GPU and once the request is about to
    be submitted to the GPU, respectively.
    
    Former condition triggers as soon as all the fences and
    dependencies have been resolved, and the latter once the
    backend is about to submit it to the GPU.
    
    New tracepoint are enabled via the new
    DRM_I915_LOW_LEVEL_TRACEPOINTS Kconfig option which is disabled
    by default to alleviate the performance impact concerns.
    
    v2: Move execute tracepoint to __i915_gem_request_submit.
