drm: Allow determining if current task is output poll worker

2018-06-16T21:22:18Z

commit 25c058ccaf2ebbc3e250ec1e199e161f91fe27d4 upstream. Introduce a helper to determine if the current task is an output poll worker. This allows us to fix a long-standing deadlock in several DRM drivers wherein the ->runtime_suspend callback waits for the output poll worker to finish and the worker in turn calls a ->detect callback which waits for runtime suspend to finish. The ->detect callback is invoked from multiple call sites and waiting for runtime suspend to finish is the correct thing to do except if it's executing in the context of the worker. v2: Expand kerneldoc to specifically mention deadlock between output poll worker and autosuspend worker as use case.

drm/ttm, drm/vmwgfx: Relax permission checking when opening surfaces

2017-07-18T17:40:26Z

commit fe25deb7737ce6c0879ccf79c99fa1221d428bf2 upstream. Previously, when a surface was opened using a legacy (non prime) handle, it was verified to have been created by a client in the same master realm. Relax this so that opening is also allowed recursively if the client already has the surface open. This works around a regression in svga mesa where opening of a shared surface is used recursively to obtain surface information.

drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil

2016-02-25T10:34:40Z

commit 64566b5e767f9bc3161055ca1b443a51afb52aad upstream. drm_fixp_from_fraction allows us to create a fixed point directly from a fraction, rather than creating fixed point values and dividing later. This avoids overflow of our 64 bit value for large numbers. drm_fixp2int_ceil allows us to return the ceiling of our fixed point value.

drm: Fix an unwanted master inheritance v2

2016-01-05T12:08:21Z

commit a0af2e538c80f3e47f1d6ddf120a153ad909e8ad upstream. A client calling drmSetMaster() using a file descriptor that was opened when another client was master would inherit the latter client's master object and all its authenticated clients. This is unwanted behaviour, and when this happens, instead allocate a brand new master object for the client calling drmSetMaster(). Fixes a BUG() throw in vmw_master_set().
