drm/amd/display: Increase size of audios array

2019-08-16T08:11:02+00:00

[ Upstream commit 7352193a33dfc9b69ba3bf6a8caea925b96243b1 ] [Why] The audios array defined in "struct resource_pool" is only 6 (MAX_PIPES) but the max number of audio devices (num_audio) is 7. In some projects, it will run out of audios array. [How] Incraese the audios array size to 7.

drm/amd/display: Only enable audio if speaker allocation exists

2019-08-16T08:11:02+00:00

[ Upstream commit 6ac25e6d5b2fbf251e9fa2f4131d42c815b43867 ] [Why] In dm_helpers_parse_edid_caps, there is a corner case where no speakers can be allocated even though the audio mode count is greater than 0. Enabling audio when no speaker allocations exists can cause issues in the video stream. [How] Add a check to not enable audio unless one or more speaker allocations exist (since doing this can cause issues in the video stream).

drm/amd/display: Fix dc_create failure handling and 666 color depths

2019-08-16T08:11:01+00:00

[ Upstream commit 0905f32977268149f06e3ce6ea4bd6d374dd891f ] [Why] It is possible (but very unlikely) that constructing dc fails before current_state is created. We support 666 color depth in some scenarios, but this isn't handled in get_norm_pix_clk. It uses exactly the same pixel clock as the 888 case. [How] Check for non null current_state before destructing. Add case for 666 color depth to get_norm_pix_clk to avoid assertion.

drm/amd/display: allocate 4 ddc engines for RV2

[ Upstream commit 67fd6c0d2de8e51e84ff3fa6e68bbd524f823e49 ] [Why] Driver will create 0, 1, and 2 ddc engines for RV2, but some platforms used 0, 1, and 3. [How] Still allocate 4 ddc engines for RV2.

drm/amd/display: put back front end initialization sequence

[ Upstream commit feb7eb522e0a7a22c1e60d386bd3c3bfa1d5e4f7 ] [Why] Seamless boot optimization removed proper front end power off sequence. In driver disable enable case, this causes driver to power gate hubp and dpp while there is still memory fetching going on, this can cause invalid memory requests to be generated which will hang data fabric.

drm/amd/display: use encoder's engine id to find matched free audio device

2019-08-16T08:11:01+00:00

[ Upstream commit 74eda776d7a4e69ec7aa1ce30a87636f14220fbb ] [Why] On some platforms, the encoder id 3 is not populated. So the encoders are not stored in right order as index (id: 0, 1, 2, 4, 5) at pool. This would cause encoders id 4 & id 5 to fail when finding corresponding audio device, defaulting to the first available audio device. As result, we cannot stream audio into two DP ports with encoders id 4 & id 5. [How] It need to create enough audio device objects (0 - 5) to perform matching. Then use encoder engine id to find matched audio device. Signed-off-by: Tai Man Reviewed-by: Charlene Liu Acked-by: Leo Li Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amd/display: fix DMCU hang when going into Modern Standby

2019-08-16T08:11:01+00:00

[ Upstream commit 1ca068ed34d6b39d336c1b0d618ed73ba8f04548 ] [why] When the system is going into suspend, set_backlight gets called after the eDP got blanked. Since smooth brightness is enabled, the driver will make a call into the DMCU to ramp the brightness. The DMCU would try to enable ABM to do so. But since the display is blanked, this ends up causing ABM1_ACE_DBUF_REG_UPDATE_PENDING to get stuck at 1, which results in a dead lock in the DMCU firmware. [how] Disable brightness ramping when the eDP display is blanked.

[ Upstream commit c7990daebe71d11a9e360b5c3b0ecd1846a3a4bb ] [WHY] Currently we don't wait for blacklight programming completion in DMCU when setting backlight level. Some sequences such as PSR static screen event trigger reprogramming requires it to be complete. [How] Add generic wait for dmcu command completion in set backlight level.

drm/amd/display: No audio endpoint for Dell MST display

[ Upstream commit 5b25e5f1a97284020abee7348427f89abdb674e8 ] [Why] There are certain MST displays (i.e. Dell P2715Q) that although have the MST feature set to off may still report it is a branch device and a non-zero value for downstream port present. This can lead to us incorrectly classifying a dp dongle connection as being active and disabling the audio endpoint for the display.
