drm/amd/display: Make dcn35_hubp_funcs static

2024-08-23T14:53:39Z

The sparse tool complains as follows: drivers/gpu/drm/amd/amdgpu/../display/dc/hubp/dcn35/dcn35_hubp.c:191:19: warning: symbol 'dcn35_hubp_funcs' was not declared. Should it be static? This symbol is not used outside of dcn35_hubp.c, so marks it static. Signed-off-by: Jinjie Ruan Signed-off-by: Alex Deucher

drm/amd/display: For FAMS2 don't program P-State force from driver

2024-08-06T14:37:18Z

P-State force programming is handled entirely by FW in FAMS2. Remove any programming from driver side to prevent incorrect programming from driver side (which may override FW programming) Signed-off-by: Alvin Lee Reviewed-by: Rodrigo Siqueira Tested-by: Daniel Wheeler Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Check null pointers before used

2024-07-23T21:07:12Z

[WHAT & HOW] Poniters, such as dc->clk_mgr, are null checked previously in the same function, so Coverity warns "implies that "dc->clk_mgr" might be null". As a result, these pointers need to be checked when used again. This fixes 10 FORWARD_NULL issues reported by Coverity.

drm/amd/display: Fix divide by zero in CURSOR_DST_X_OFFSET calculation

2024-07-01T20:06:53Z

[Why] Certain situations cause pipes to have a recout of 0, such as when the dst_rect lies completely outside of a given ODM slice. [How] Skip calculation that transforms cursor coordinates to viewport space.

drm/amd/display: Program CURSOR_DST_X_OFFSET in viewport space

2024-06-27T21:10:37Z

[WHAT & HOW] According to register specifications, the CURSOR_DST_X_OFFSET is relative to the start of the data viewport, not RECOUT space. In this case we must transform the cursor coordinates passed to hubp401_cursor_set_position into viewport space to program this register. This fixes an underflow issue that occurs in scaled mode with low refresh rate.

drm/amd/display: Fix cursor issues with ODMs and HW rotations

2024-06-27T21:10:36Z

[WHY & HOW] Current code for cursor positions does not work properly with different ODM options and HW rotations like ODM 2to1, 3to1 and 4to1, and has different issues depending on angle of HW rotations. [HOW] Fixed these issues so to work properly when ODM is used with HW rotations.
