2022-01-18drm/amd/display: move calcs folder into DMLIsabella Basso
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.

2017-12-14drm/amd/display: Add disclaimer to BW and DML code provided by HWHarry Wentland
This code can sometimes look troubling but we trust it as it comes from HW teams with a guarantee of correctness.

2017-12-14drm/amd/display: Use macro for isnan checkHarry Wentland
In code provided by HW teams we do a NaN check on floats by comparing the number against itself. This confuses most people including myself. Macro it out to make it self-explanatory. Don't do a NaN check for int. v2: parantheses around 'number' expression Signed-off-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2017-10-21Revert "amdgpu/dc: inline a bunch of float operations."Harry Wentland
This reverts commit d1209512e028a917e6e70b13297ff185234ba24d. Unfortunately these clash with our DML update from the HW guys. Rerolling this after the fact won't save us anything anymore, unfortunately so we're back to non-inline for this. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
