drm/amd/display: Fix prefetch bandwidth calculation for DCN3.1

2021-11-02T18:50:55Z

commit c938aed88f8259dc913b717a32319101c66e87a9 upstream. [Why] Prefetch BW calculated is lower than the DML reference because of a porting error that's excluding cursor and row bandwidth from the pixel data bandwidth. [How] Change the dml_max4 to dml_max3 and include cursor and row bandwidth in the same calculation as the rest of the pixel data during vactive.

drm/amd/display: Guard DST_Y_PREFETCH register overflow in DCN21

2021-07-27T16:43:09Z

[why] DST_Y_PREFETCH can overflow when DestinationLinesForPrefetch values are too large due to the former being limited to 8 bits. [how] Set the maximum value of DestinationLinesForPrefetch to be 255 * refclk period.

drm/amd/display: Respect CONFIG_FRAME_WARN=0 in dml Makefile

2021-07-01T04:05:18Z

Setting CONFIG_FRAME_WARN=0 should disable 'stack frame larger than' warnings. This is useful for example in KASAN builds. Make the dml Makefile respect this config. Fixes the following build warnings with CONFIG_KASAN=y and CONFIG_FRAME_WARN=0: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3642:6: warning: stack frame size of 2216 bytes in function 'dml30_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than=] drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c:3957:6: warning: stack frame size of 2568 bytes in function 'dml31_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than=] Reviewed-by: Harry Wentland Signed-off-by: Reka Norman Signed-off-by: Alex Deucher
