drm/amd/display: remove DC_FP_* wrapper from dml folder

2022-04-01T03:05:54Z

FPU documentation states that developers must not use DC_FP_START/END inside dml files, but use this macro to wrap calls to FPU functions in dc folder (outside dml folder). Therefore, this patch removes DC_FP_* wrappers from dml folder and wraps calls for these FPU operations outside dml, as required.

drm/amd/display: detach fpu operations from dcn10_validate_bandwidth in calcs

2022-04-01T03:05:54Z

dcn10_validate_bandwidth is only used on dcn10 files, but is declared in dcn_calcs files. Rename dcn10_* to dcn_* in calcs, remove DC_FP_* wrapper inside DML folder and create an specific dcn10_validate_bandwidth in dcn10_resources that calls dcn_validate_bandwidth and properly wraps that FPU function with DC_FP_* macro.

drm/amdgpu/display: Remove t_srx_delay_us.

2022-01-27T20:47:34Z

Unused. Convert the divisions into asserts on the divisor, to debug why it is zero. The divide by zero is suspected of causing kernel panics. While I have no idea where the zero is coming from I think this patch is a positive either way. Reviewed-by: Harry Wentland Signed-off-by: Bas Nieuwenhuizen Signed-off-by: Alex Deucher

drm/amd/display/dc/calcs/dce_calcs: Fix a memleak in calculate_bandwidth()

2022-01-25T23:00:36Z

In calculate_bandwidth(), the tag free_sclk and free_yclk are reversed, which could lead to a memory leak of yclk. Fix this bug by changing the location of free_sclk and free_yclk. This bug was found by a static analyzer. Builds with 'make allyesconfig' show no new warnings, and our static analyzer no longer warns about this code.

drm/amd/display: move calcs folder into DML

2022-01-18T22:43:36Z

The calcs folder has FPU code on it, which should be isolated inside the DML folder as per https://patchwork.freedesktop.org/series/93042/. This commit aims single-handedly to correct the location of such FPU code and does not refactor any functions. Changes since v2: - Corrected problems to compile when DCN was disabled.
