drm/amd/display: Reset DMUB mailbox SW state after HW reset

2023-02-02T03:45:50+00:00

[Why] Otherwise we can be out of sync with what's in the hardware, leading to us rerunning every command that's presently in the ringbuffer. [How] Reset software state for the mailboxes in hw_reset callback. This is already done as part of the mailbox init in hw_init, but we do need to remember to reset the last cached wptr value as well here.

drm/amd/display: Waiting for 1 frame to fix the flash issue on PSR1

2022-11-09T22:24:57+00:00

[Why] Needs more frames waiting before the PSR_Exit sending for the specific TCON. [How] Add relock_delay_frame_cnt to control how many frames waiting are needed before the PSR_Exit sending. The default value is 0. The Driver side can set this variable for specific TCONs.

drm/amd/display: Implement secure display on DCN21

2022-10-27T18:42:32+00:00

[Why] Porting secure display feature from DCN10 to DCN21. Support single display for now and will extend to multiple displays. [How] - use workqueue to offload works for dmub or dmcu firmware - after receiving ROI update from userspace, set skip_frame_cnt to 1 - refactor amdgpu_dm_crtc_handle_crc_window_irq() - disable PSR before activating secure_display on a crtc - check if secure_display is activated before enabling psr - only work for single display for now.

drm/amd/display: Use set_vtotal_min_max to configure OTG VTOTAL

In multiple parts of the DCN code, we write directly to the OTG_V_TOTAL_* registers in some OPTC functions. Let's avoid it by using the set_vtotal_min_max. Tested-by: Daniel Wheeler Acked-by: Qingqing Zhuo Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Display does not light up after S4 resume

2022-10-10T21:32:55+00:00

[Why] Dpia hpd interrupt processing is disabled when entering S4/S0i3 and would be reenabled after detection completes during resuming. Because, keeping hpd interrupts enabled during detection leads to multiple detections for the same hpd transition. There is a S4 case where dpia hpd interrupt is missed when driver is in transitioning from hpd interrupt processing disable to enable and the display does not light up. [How] - Added dmub inbox command DMUB_CMD__DPIA_HPD_INT_ENABLE to explicitly control dmub to issue dpia hpd interrupt or not. If dpia hpd interrupt is disabled, dmub will keep the hpd pending and post it once driver reenables dpia hpd interrupt or when querying with DMUB_CMD__QUERY_HPD_STATE. - Added dmub boot option dpia_hpd_int_enable_supported to notify dmub about whether DMUB_CMD__DPIA_HPD_INT_ENABLE command would be used.

drm/amd/display: Use the same cursor info across features

2022-10-10T21:32:55+00:00

Since different features would need to update cursor registers, However, they would use different approaches. To unify varied methods, this refactor is implemented the same update cursor info method for current varied features.
