[Intel-gfx] [i-g-t PATCH v2 0/2] Avoid calling DRM_IOCTL_I915_GET_PIPE_FROM_CRTC_ID

[Tomeu Vizoso]

Hi,

these two patches remove the two last uses of
DRM_IOCTL_I915_GET_PIPE_FROM_CRTC_ID, with the intention of making the
tests runnable on !i915.

I have looked in the kernel and cannot find any point where the pipe ID
didn't match the index of the CRTC as returned by GETRESOURCES, so I'm
not increasing the required libdrm version for now.

I wasn't able to fully run intel-gpu-overlay with the kms backend, but I
have checked with gdb that the changed code keeps working correctly (on
my system the CRTC with ID 21 is chosen for the pipe 0).

Thanks,

Tomeu

Changes in v2:
- Fix include path as suggested by Thomas
- Remove some dead code

Micah Fedke (2):
  lib: update kmstest_get_pipe_from_crtc_id
  overlay: Remove crtc<->pipe mapping code from kms-overlay
