drm/amd/display: Update SR watermarks for DCN314

2022-11-09T22:59:10Z

[Why & How] New values requested by hardware after fine-tuning. Update for all memory types. Reviewed-by: Jun Lei Acked-by: Alan Liu Signed-off-by: Nicholas Kazlauskas Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org # 6.0.x

drm/amd/display: Reduce number of arguments of dml314's CalculateFlipSchedule()

2022-09-20T16:42:32Z

Most of the arguments are identical between the two call sites and they can be accessed through the 'struct vba_vars_st' pointer. This reduces the total amount of stack space that dml314_ModeSupportAndSystemConfigurationFull() uses by 112 bytes with LLVM 16 (1976 -> 1864), helping clear up the following clang warning: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn314/display_mode_vba_314.c:4020:6: error: stack frame size (2216) exceeds limit (2048) in 'dml314_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than] void dml314_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) ^ 1 error generated.

drm/amd/display: Modify DML to adjust Vstartup Position

2022-09-19T19:16:19Z

[WHY] The Vstartup position should be as late as possible to maximize power saving with the current. Calculation of Vstartup in DML does not take into account as SDP signal. [HOW] Made necessary changes to calculate the correct Vstartup position in DML to account for AS SDP * Overriding the VBlankNom value in certain cases otherwise it will use the default value * Bypassing the condition for adjust_sync_Vstartup * Overriding vblank_nom_input with VBlankNom that is set in the SW Layer Reviewed-by: Anthony Koo Acked-by: Wayne Lin Signed-off-by: muansari Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Correct dram channel width for dcn314

2022-09-13T18:33:00Z

[Why] The interpretation of the number of memory channels differ by memory type, and this affects channel width for the DML input. [How] Set dram channel width according to memory type for dcn314.

drm/amd/display: Relax swizzle checks for video non-RGB formats on DCN314

2022-09-13T18:33:00Z

[Why] HW can support the display swizzle modes for video, and those are preferable over standard or linear for decode use. [How] Remove the check for DCN314. Tested-by: Daniel Wheeler Reviewed-by: Jun Lei Acked-by: Pavle Kotarac Signed-off-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amd/display: Hook up DCN314 specific dml implementation

2022-09-13T18:32:59Z

[Why & How] Add support for the DML314 functions and hook up DCN314 to use them. This has some necessary additions for calculating Max VSTARTUP for future features, but there's also some changes that we have to make for pixel format/swizzle support. That will come in a following patch to make this transition easier to bisect.

drm/amd/display: Fix compilation errors on DCN314

2022-09-13T18:32:59Z

We have some compilation errors in some DML files from DCN314 that we never noticed because we were not compiling some of the DML files. This commit fixes those syntax errors before we enable the compilation. Cc: Roman Li Tested-by: Daniel Wheeler Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher
