From: Mario Limonciello <mario.limonciello@xxxxxxx> Many people have reported a series of issues that lead to divide by zero errors in DML2 code on DCN 3.5. This divide by zero error is caused by accessing outside of the bound of what is initialized on an array for the number of planes. The first patch in the series fixes the immediate issue. This patch should go to fixes and stable. The remaining patches fix what appears to be the same problem in other code in both DML and DML2 that has (presumably) been copy/pasted for loop iterators. Mario Limonciello (4): drm/amd/display: Adjust plane init for off by one error drm/amd/display: Correct off by one errors in DML drm/amd/display: Correct some suspect code indentation drm/amd/display: Correct off by one errors in DML2 .../dc/dml/dcn32/display_mode_vba_32.c | 68 ++++----- .../amd/display/dc/dml2/display_mode_core.c | 131 +++++++++--------- .../src/dml2_core/dml2_core_dcn4_calcs.c | 40 +++--- .../dml21/src/dml2_core/dml2_core_shared.c | 50 +++---- 4 files changed, 144 insertions(+), 145 deletions(-) -- 2.43.0
