Message

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()".
v3:
  - Rebase after a long time for fresh CI results.

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()
