2023-03-14drm/amd/display: convert link.h functions to function pointer styleWenjing Liu1-130/+184
[Why & How] All dc subcomponents should call another dc component via function pointers stored in a component structure. This is part of dc coding convention since the beginning. The reason behind this is to improve encapsulation and polymorphism. The function contract is extracted into a single link service structure defined in link.h header file and implemented only in link_factory.c instead of spreading across multiple files in link component file structure.

2023-02-15drm/amd/display: move public dc link function implementation to dc_link_exportsWenjing Liu1-0/+18
[why] Link is a subcomponent in dc. DM should be aware of dc link structure as one of the abstracted objects maintained by dc. However it should have no idea of the existence of a link component in dc dedicated to maintain the states of dc link structure. As such we are moving link interfaces out of dc_link.h and directly added to dc.h. We are grandually fading out the explicit inclusion of dc_link header and eventually delete it. On dc side, since link is a subcomponent behind dc interfaces, it is not a good idea to implement dc interfaces in each individual subcomponent of link which is already a subcomponent of dc. So we are decoupling it by implementing a dc_link_exports in dc. This file will be a thin translation layer that breaks the dependency so link is able to make interface changes without breaking DM.

2022-10-27drm/amd/display: Drop struct crc_region and reuse struct rectAlan Liu1-1/+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 <mark.broadworth@amd.com> Reviewed-by: Wayne Lin <Wayne.Lin@amd.com> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alan Liu <HaoPing.Liu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2022-10-27drm/amd/display: Implement secure display on DCN21Alan Liu1-14/+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.

[Why] Read set_power_state dpcd after HPD cause USB4 CTS 4.2.1.1 [How] Read LTTPR caps first. If aux channel not ready, wake up aux channel. If wake up aux channel return pass, retrieve lttpr caps again. If wake up aux channel return false, register a detection retry timer.

2022-10-24drm/amd/display: remove audio mute control in hpo dpWenjing Liu1-3/+0
VPG doesn't have the ability to mute audio output by sending all 0s in audio SDP. The existing implemention is disabling audio SDP instead. This is same as what dp_audio_enable does. Since it is no longer referenced by any callers, we decided to remove this interface for simplicity.
