drm/amd/display: Refactor HWSS into component folder

2023-10-09T21:00:09+00:00

[why] Rename hw_sequencer to hwseq. Move all hwseq files to unique folder hwss. [how] creating hwss repo in dc, and moved the dcnxx_hwseq.c and .h files into corresponding new folders inside the hwss and cleared the linkage errors by adding relative paths in the Makefile.template.

drm/amd/display: Introduce DML2

2023-10-09T20:48:51+00:00

DC is transitioning from DML to DML2, and this commit introduces all the required changes for some of the already available ASICs and adds the required code infra to support new ASICs under DML2. DML2 is also a generated code that provides better mode verification and programming models for software/hardware, and it enables a better way to create validation tools. This version is more like a middle step to the complete transition to the DML2 version. Changes since V1: - Alex: Fix typos Changes since V2: - Update DC includes Changes since V3: - Fix 32 bit compilation issues on x86 Changes since V4: - Avoid compilation of DML2 on some not supported 32-bit architecture - Update commit message Co-developed-by: Rodrigo Siqueira Signed-off-by: Rodrigo Siqueira Co-developed-by: Roman Li Signed-off-by: Roman Li Signed-off-by: Qingqing Zhuo Signed-off-by: Alex Deucher

drm/amd/display: Move dml code under CONFIG_DRM_AMD_DC_FP guard

2023-10-09T20:48:45+00:00

For some reason, the dml code is not guarded under CONFIG_DRM_AMD_DC_FP in the Makefile. This commit moves the dml code under the DC_FP guard. Reviewed-by: Qingqing Zhuo Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Remove wait while locked

2023-08-30T19:36:38+00:00

[Why] We wait for mpc idle while in a locked state, leading to potential deadlock. [What] Move the wait_for_idle call to outside of HW lock. This and a call to wait_drr_doublebuffer_pending_clear are moved added to a new static helper function called wait_for_outstanding_hw_updates, to make the interface clearer.

drm/amd/display: Rename DCN config to FP

2023-03-07T19:22:40+00:00

[Why & How] The only reason we have the DCN config is for floating point support. Rename it to make that clear and (hopefully) avoid misuse of the config in the future.

drm/amd/display: Build DSC without DCN config

2023-03-07T19:22:40+00:00

[Why & How] DSC needs DCN but we are trying reduce the usage of the DCN flag. It's easier to build the DSC code sprinkled around DC core and the DMs and just guard the place where DSC uses floating point code. Since DSC is never enabled on non-DCN ASICs this won't have any effect.

drm/amd/display: move public dc link function implementation to dc_link_exports

2023-02-14T21:06:28+00:00

[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.

drm/amd/display: break down dc_link.c

2023-02-08T22:15:51+00:00

[why] dc_link contains over 30k line of code, the decision is to break it down to files residing in link folder based on functionality. This change is the last break down change which will remove dc_link.c file after everything is broken down. [how] Move remaining dc_link.c functions into link_detection, link_dpms, link_validation, link_resource, and link_fpga and remove dc_link.
