* drm/amd/display: Drop struct crc_region and reuse struct rectAlan Liu2022-10-271-1/+1
| | | | | | | | | | | | | | | | [Why] reuse struct rect rather than adding a new struct. [How] - Userspace keeps inputting x_start, y_start, x_end, y_end - We translate data to x, y, width, height in code flow to store - translate back to x_start, y_start, x_end, y_end before programming HW Tested-by: Mark Broadworth <[email protected]> Reviewed-by: Wayne Lin <[email protected]> Acked-by: Rodrigo Siqueira <[email protected]> Signed-off-by: Alan Liu <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
* drm/amd/display: Implement secure display on DCN21Alan Liu2022-10-271-14/+0
| | | | | | | | | | | | | | | | | | | | [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: Engage PSR synchronouslyKrunoslav Kovac2020-11-101-1/+1
| | | | | | | | | | | | [Why & How] The intended use is to force PSR into active state and ignore all events until explicit EXIT. A new event force_static is added to power module.

* drm/amd/display: Redefine DMCU_SCRATCH to identify DMCU stateMartin Tsai2019-01-141-2/+8
| | | | | | | | | | | | | | | | | | | [why] To resume system before entering S0i3 completely will cause PSP not reload DMCU FW since there is not HW power state change. In this case, driver cannot get correct DMCU version from IRAM since driver override it and DMCU didn't reload to update it. It makes driver return false in dcn10_dmcu_init().

* drm/amd/display: Prevent PSR from being enabled if initialization failsAnthony Koo2018-07-271-1/+1
| | | | | | | | | | | | | | | | | | [Why] PSR_SET command is sent to the microcontroller in order to initialize parameters needed for PSR feature, such as telling the microcontroller which pipe is driving the PSR supported panel. When this command is skipped or fails, the microcontroller may program the wrong thing if driver tries to enable PSR. [How] If PSR_SET fails, do not set psr_enable flag to indicate the feature is not yet initialized.

* drm/amd/display: DMCU FW loading from PSPAnthony Koo2017-12-041-0/+16
| | | | | | | | | | | | | | | | | | | | | | Update the programming sequence to allow DMCU firmware to be loaded by PSP. This code detects whether the firmware is loaded and does a check to verify the expected interface version and checks for correct response from micro controller. Added registry key method to allow force loading of firmware from kernel mode driver for test purposes. This is old method of firmware loading without PSP. Moved some init sequences into dc/dmcu. Changed loading sequence to initialize IRAM after firmware completely loaded. Firmware will now disable features that use IRAM until initialized.
