[Intel-gfx] [RESEND PATCH v14 0/2] New debugfs API for capturing CRC of frames

Hi, here are the last two patches that remain to be merged in this series, rebased on today's drm-tip. Thanks, Tomeu Tomeu Vizoso (2): drm/i915: Use new CRC debugfs API drm/i915: Put "cooked" vlank counters in frame CRC lines drivers/gpu/drm/i915/i915_drv.h | 1 +

[Intel-gfx] [RESEND PATCH v14 1/2] drm/i915: Use new CRC debugfs API

the new ABI we skip the 1st or 2nd frames. v9: - Add stub for intel_crtc_set_crc_source. v12: - Rebased. - Remove stub for intel_crtc_set_crc_source and instead set the callback to NULL (Jani Nikula). v15: - Rebased. Signed-off-by: Tomeu Vizoso Reviewed-by: Emil

[Intel-gfx] [RESEND PATCH v14 2/2] drm/i915: Put "cooked" vlank counters in frame CRC lines

Use drm_accurate_vblank_count so we have the full 32 bit to represent the frame counter and userspace has a simpler way of knowing when the counter wraps around. Signed-off-by: Tomeu Vizoso Reviewed-by: Emil Velikov Reviewed-by: Robert Foss --- drivers/gpu/drm/i915/i915_irq.c | 6 +++--- 1
