Subject: [PATCH 02/10] tools/include: Sync uapi/drm/i915_drm.h with the kernel sources
To pick up changes from:
0f1bb41bf396 drm/i915: Support replaying GPU hangs with captured context image
This should be used to beautify DRM syscall arguments and it addresses
these tools/perf build warnings:
Warning: Kernel ABI header differences:
diff -u tools/include/uapi/drm/i915_drm.h include/uapi/drm/i915_drm.h
Please see tools/include/uapi/README for details (it's in the first patch
of this series).
