[PATCH 0/2] drm: update the ioctl handler

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Finally got around to it. This patchset implements some updates to the
drm ioctl handler that were first raised by Daniel Vetter in [1].
Namely:

- Flush concurrent processes that can change the modeset when
DRM masters are set/dropped or a lease is revoked
- Unexport drm_ioctl_permit()

Thoughts and comments would be very appreciated.

Best wishes,
