drm/amd/display: simplify dml log2 function

2020-05-28T18:00:50Z

Current implementation is slightly inaccurate and will often result in truncation/floor operation decrementing an exact integer output by 1. Only rounded down output is ever expected, just extract the fp exponent for this to increase performance and avoid any truncation issues.

drm/amd/display: fix dml log2 function

2020-05-28T18:00:48Z

This change removes internal rounding in dml_log2 function. Dml_log2 is expected to return a float output. In case an int is needed dml will floor the output on it's own. Signed-off-by: Dmytro Laktyushkin Reviewed-by: Eric Bernstein Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Remove dml_common_def file

2020-05-21T16:48:43Z

During the rework for removing the FPU issues, I found the following warning: [..] dml_common_defs.o: warning: objtool: dml_round()+0x9: FPU instruction outside of kernel_fpu_{begin,end}() This file has a single function that does not need to be in a specific file. This commit drop dml_common_defs file, and move dml_round function to dml_inline_defs.

This reverts commit 3e8c3108dab197858e74dbb740c5312ae636ea9b. Unfortunately these clash with our DML update from the HW guys. Will attempt to reroll them after. Signed-off-by: Alex Deucher
