* | drm/amd/display: remove sink reference in dc_stream_stateJun Lei2019-01-1417-94/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [why] dc_stream_state containing a pointer to sink is poor design. Sink describes the display, and the specifications or capabilities it has. That information is irrelevant for dc_stream_state, which describes hardware state, and is generally used for hardware programming. It could further be argued that dc_sink itself is just a convenience dc provides, and DC should be perfectly capable of programming hardware without any dc_sinks (for example, emulated sinks). [how] Phase 1: Deprecate use of dc_sink pointer in dc_stream. Most references are trivial to remove, but some call sites are risky (such as is_timing_changed) with no obvious logical replacement. These will be removed in follow up change. Add dc_link pointer to dc_stream. This is the typical reason DC really needed sink pointer, and most call sites are replaced with this. DMs also need minor updates, as all 3 DMs leverage stream->sink for some functionality. this is replaced instead by a pointer to private data inside dc_stream_state, which is used by DMs as a quality of life improvment for some key functionality. it allows DMs to set pointers have to their own objects which associate OS objects to dc_stream_states (such as DisplayTarget and amdgpu_dm_connector). Without the private pointer, DMs would be forced to perform a lookup for callbacks.

* drm/amd/display: fix sporadic multiple aux transaction failureYogesh Mohan Marimuthu2018-11-302-51/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | [why] When there are multiple aux transaction in parallel, it is sometime sporadically the aux transaction starts to continuously fail. The aux transaction was failing because the busy bit for the given gpio pin was always set. The busy bit was alway set because the programming sequence to read, modify and write busy bit was not atomic. Due to which when multiple threads are trying to modify the busy bits for their gpio pins in the same integer variable sometimes the busy bits integer variable is written with old data causing failure. [how] Instead of using individual bits to track gpio pins and grouping them to integers, one byte will be allcoated for each gpio pin. Now whenever a gpio pin needs to be set to mark being used, only writing a value of one to that byte is sufficient, other bytes are not impacted. Also no need to have atomicity with bytes unlike with bits.

* drm/amd: Add abm level drm propertyDavid Francis2018-11-262-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adaptive Backlight Management (ABM) is a feature that reduces backlight level to save power, while increasing pixel contrast and pixel luminance to maintain readability and image quality. ABM will adjust in response to the pixel luminance of the displayed content. ABM is made available as a drm property on eDP monitors called "abm level", which ranges from 0 to 4. When this property is set to 0, ABM is off. Levels 1 to 4 represent different ranges of backlight reduction. At higher levels both the backlight reduction and pixel adjustment will be greater. ABM requires DMCU firmware, which is currently available for Raven ASICs only. If the feature does not work, please ensure your firmware is up to date. v2: Fix commit message, only attach property if DMCU loaded v3: Store ABM level in crtc state to accommodate dc v4: Fix ABM saving on dpms cycle Signed-off-by: David Francis <David.Francis@amd.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
