Since the relocations are no longer performed under a global struct_mutex, or any other lock, that is also held by pagefault handlers, we can relax and allow our fast path to take a fault. As we no longer need to abort the fast path for lock avoidance, we no longer need the slow path handling at all. Signed-off-by:

When applying the context-barrier, we only care about the current engines, as the next set of engines will be naturally after the barrier. So we can skip holding the ctx->engines_mutex while constructing the request by taking a sneaky reference to the i915_gem_engines instead. Signed-off-by:

Most of the kms_frontbuffer_tracking tests disables the feature being tested, draw, get the CRC then enable the feature, draw again, get the CRC and check if it matches. Some times it is able to do that with a fastset, so intel_pre_plane_update() is executed but intel_fbc_can_flip_nuke() was not checking if FBC is now enabled in this CRTC leaving FBC active and

Always wait on the start of the signaler request to reduce the problem of dequeueing the bonded pair too early -- we want both payloads to start at the same time, with no latency, and yet still allow others to make full use of the slack in the system. This reduce the amount of time we spend waiting on the semaphore used to synchronise the start of the bonded payload. Signed-off-by:

gmbus/aux may be clocked by cdclk, thus we should make sure no transfers are ongoing while the cdclk frequency is being changed. We do that by simply grabbing all the gmbus/aux mutexes. No one else should be holding any more than one of those at a time so the lock ordering here shouldn't matter. v2: Use mutex_lock_nest_lock() (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

The low level read_lut() functions don't need the entire crtc state as they know exactly what they're reading. Just need to pass in the crtc to get at the pipe. This now neatly mirrors the load_lut() direction. Signed-off-by:

PIPEGCMAX is a 11.6 (or 1.16 if you will) value. Ie. it can represent a value of 1.0 when the maximum we can store in the software LUT is 0.ffff. Clamp the value so that it gets saturated to the max the uapi supports. Signed-off-by:

A variable called 'i' having an unsigned type is just looking for trouble, and using a sized type generally makes no sense either. Change all of them to just plain old int. And do the same for some 'lut_size' variables which generally provide the loop end codition for 'i'. Signed-off-by:
