2018-02-20drm/doc: Polish for drm_mode_parse_command_line_for_connectorDaniel Vetter
Quoting the module option format looks soo much nicer, and avoids sphinx spewing errors about markup issues. v2: Fix typo in commit message (Thierry).

2018-02-20drm/docs: Document "scaling mode" property betterDaniel Vetter
Move it out of the csv dungeon. While at it add the missing link to the helper functions for setting up the "panel rotation" property. Also OCD how we list enum property values and their corresponding docs. Going for a nest definition list seams cleanest, no need for also making it an uordered list.

2018-02-20drm/docs: Discourage adding more to kms-properties.csvDaniel Vetter
Motivated by patch review. The table is really hard to read in source form, hard to edit, and we've moved away to more focused sections about specific features and how they're exposed in properties. Those sections can then more easily enumerate options, link to helper functions and other parts of the docs. All things that get ugly real fast in the docs.

2018-02-20drm/i915: Track number of pending freed objectsChris Wilson
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 <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180219220631.25001-1-chris@chris-wilson.co.uk

2018-02-19drm/amd/display: When enabling CRC, disable dither & enable truncationLeo (Sunpeng) Li
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.
