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.

drm/amd/display: merge dc_link_dp into dc_link

2023-01-24T18:26:25+00:00

[why] Temporarly merge dc_link_dp functions into dc_link for the purpose of removing dc_link_dp files. This is a transitional change for later commits where we will further refactor dc_link file.

drm/amd/display: Enable building new display engine with KCOV enabled

2022-07-18T20:42:38+00:00

The new display engine uses floating point math, which is not supported by KCOV. Commit 9d1d02ff3678 ("drm/amd/display: Don't build DCN1 when kcov is enabled") tried to work around the problem by disabling CONFIG_DRM_AMD_DC_DCN if KCOV_INSTRUMENT_ALL and KCOV_ENABLE_COMPARISONS are enabled. The result is that KCOV can not be enabled on systems which require this display engine. A much simpler and less invasive solution is to disable KCOV selectively when compiling the display enagine while keeping it enabled for the rest of the kernel.

There are several things wrong here. First, none of these numbers are FP, so there is no need to cast to double. Next make sure to use proper 64 bit division helpers. Fixes: 85f4bc0c333c ("drm/amd/display: Add SubVP required code") Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher

This commit enables the SubVP feature. To achieve that, we need to: - Don't force p-state disallow on SubVP (can't block dummy p-state) - Send calculated watermark to DMCUB for SubVP - Adjust CAB mode message to PMFW - Add a proper locking sequence for SubVP - Various fixes to SubVP static analysis and determining SubVP config - Currently SubVP not supported with pipe split so merge all pipes before setting up SubVp Reviewed-by: Jun Lei Acked-by: Rodrigo Siqueira Acked-by: Alan Liu Signed-off-by: Alvin Lee Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher
