drm/amd/dc/dce120: Fix audio register mapping, stop triggering KASAN

2022-11-23T14:01:53+00:00

There's been a very long running bug that seems to have been neglected for a while, where amdgpu consistently triggers a KASAN error at start: BUG: KASAN: global-out-of-bounds in read_indirect_azalia_reg+0x1d4/0x2a0 [amdgpu] Read of size 4 at addr ffffffffc2274b28 by task modprobe/1889 After digging through amd's rather creative method for accessing registers, I eventually discovered the problem likely has to do with the fact that on my dce120 GPU there are supposedly 7 sets of audio registers. But we only define a register mapping for 6 sets. So, fix this and fix the KASAN warning finally.

drm/amd/display/dc/dce120/Makefile: Ignore -Woverride-init warning

2021-01-14T04:53:26+00:00

This file uses a complex abstracted set of hierarchical macros to setup its applicable register lists within constant structures. However in the case of TMDS_CNTL we wish to mark it as not applicable for this use-case. One method would be to de-const all of the definitions and users, then manually zero out TMDS_CNTL from the list. Another would be to create a new set of hierarchical macros to omit TMDS_CNTL entirely. Both would entail a great deal of unnecessary changes and maintenance burden. Instead, let's just silence the warning.
