drm/amd/display: Fix exception from AUX acquire failure

2019-05-31T13:43:58+00:00

[ Upstream commit dcf1a988678e2e39ce2b4115b8ce14d208c8c481 ] [Why] AUX arbitration occurs between SW and FW components. When AUX acquire fails, it causes engine->ddc to be NULL, which leads to an exception when we try to release the AUX engine. [How] When AUX engine acquire fails, it should return from the function without trying to continue the operation. The upper level will determine if it wants to retry. i.e. dce_aux_transfer_with_retries will be used and retry.

drm/amd/display: extending AUX SW Timeout

2019-04-11T15:03:08+00:00

[Why] AUX takes longer to reply when using active DP-DVI dongle on some asics resulting in up to 2000+ us edid read (timeout). [How] 1. Adjust AUX poll to match spec 2. Extend the SW timeout. This does not affect normal operation since we exit the loop as soon as AUX acks.

drm/amd/display: send pipe set command to dmcu when backlight is set

2019-02-19T20:58:26+00:00

[Why] Previously, a change removed code that would send a pipe set command to dmcu each time the backlight was set, as it was thought to be superfluous. However, it is possible for the backlight to be set before a valid pipe has been set, which causes DMCU to hang after a DPMS restore on some systems. [How] Send a pipe set command to DMCU prior to setting the backlight. Signed-off-by: Josip Pavic Reviewed-by: Anthony Koo Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: send pipe set command to dmcu when stream unblanks

2019-02-19T20:58:26+00:00

[Why] When stream is blanked, pipe set command is sent to dmcu to notify it that the abm pipe is disabled. When stream is unblanked, no notification is made to dmcu that the abm pipe has been enabled, resulting in abm not being enabled in the firmware.

2019-02-18T23:01:07+00:00

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find.

drm/amd/display: interface to check if timing can be seamless

2019-02-06T18:30:44+00:00

[Why] Need to figure out whether a timing we want to commit matches something that GOP already programmed, in which case we can decide to some optimizations [How] 1. Add way to check for DIG FE 2. Add way to check for matching OTG timing 3. Add way to check for matching pixel clock (if possible) - Currently only support DP for pixel clock, since it is easy to calc Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher
