2018-02-20drm/i915: Don't set cursor pipe select bits on g4x+Ville Syrjälä1-1/+2
G4x cursor control registers still allow us to write to the pipe select bits even though cursors are supposed to be fixed to a specific pipe. Bspec tells us that we should only ever write 0 to these bits. Let's follow that recommendation. On ilk+ the bits become hardwired to 0. Also looks like ICL repurposes these bits for some other use, so we had better stop setting them to bogus values there.

2018-02-20drm/i915: Assert that we don't overflow frontbuffer tracking bitsVille Syrjälä1-4/+8
Add some compile time assrts to the frontbuffer tracking to make sure that we have enough bits per pipe to cover all the planes, and that we have enough total bits to cover all the planes across all pipes. We'll ignore any potential clash between the overlay bit and the plane bits because that will allow us to keep using a total of 32 bits for the foreseeable future. While at it change the macros to use BIT() and GENMASK(). The latter gets rid of the hardcoded 0xff and thus means we can change the number of bits per pipe by just changing INTEL_FRONTBUFFER_BITS_PER_PIPE.

2018-02-20drm/i915: Track number of pending freed objectsChris Wilson3-4/+15
During igt, we frequently call into the driver to reset both HW and driver state (idling the device, waiting for it to become idle and freeing off old objects) to ensure that we start each test/subtest/pass from known state. This process incurs an RCU barrier or two to ensure that any such pending frees are indeed flushed before we return. However, unconditionally waiting on the RCU barrier adds needless delay to many callers, which adds up to several seconds when repeated thousands of times. We can skip the rcu_barrier() if by tracking how many outstanding frees we have, we know there are none. The same path is used along suspend, where we may be able to save the unconditional RCU barrier. To put it into perspective with a completely meaningless microbenchmark, igt/gem_sync/idle is improved from 50ms to 30us on bdw. v2: Remove the extra synchronize_rcu() inside i915_drop_caches_set() Signed-off-by: Chris Wilson <[email protected]> Cc: Mika Kuoppala <[email protected]> Cc: Joonas Lahtinen <[email protected]> Reviewed-by: Tvrtko Ursulin <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2018-02-19drm/amd/display: When enabling CRC, disable dither & enable truncationLeo (Sunpeng) Li2-5/+20
When user-mode is using 8bpc, the hardware represents it internally using a higher bit depth. This causes problems when comparing CRCs for color managment tests. We need to disable dithering as well, since it makes CRC values non-deterministic. It's easy to see why dithering needs to be disabled, The reason why truncation also needs to be enabled is better described with an example. Consider the folowing which tests the color transform matrix (CTM): Expected CRC = FB_A -> Degamma (Bypassed) -> CTM (Bypassed) | v Obtain CRC <- Regamma(Bypassed) Actual CRC = FB_B -> Degamma (Bypassed) -> CTM (0.5*Identity) | v Obtain CRC <- Regamma(Bypassed) FB_A contains a solid red color at half intensity (127 @ 8bpc) FB_B contains a solid red color at full intensity (255 @ 8bpc) We expect that Expected CRC = Actual CRC, but that's not the case. When the CTM is applied, the output is at half intensity, but also at a higher bit depth within hardware. i.e. 255/2 = 127.5: not representable in 8bpc, but can be at 10bpc. This causes the two CRC's to be different. The solution is to truncate the output bit depth to the same as input when enabling CRC capture. Since Linux only supports 8bpc, hard code that for now.
