drm/amd/display: Add support to configure CRC window on specific CRC instance

2025-01-10T17:03:45Z

[Why] Have the need to specify the CRC window on specific CRC engine. dc_stream_configure_crc() today calculates CRC on crc engine 0 only and always resets CRC engine at first. [How] Add index parameter to dc_stream_configure_crc() for selecting the desired crc engine. Additionally, add another parameter to specify whether to skip the default reset of crc engine.

[Why & How] Since now we can set multiple crc windows for secure display, add a new input parameter for dc_stream_get_crc to indicate to fetch crc from which crc engine. Reviewed-by: HaoPing Liu Signed-off-by: Wayne Lin Signed-off-by: Roman Li Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Add P-State Keepout to dcn401 Global Sync

kbuild: make -Woverride-init warnings more consistent

2024-03-31T02:32:26Z

The -Woverride-init warn about code that may be intentional or not, but the inintentional ones tend to be real bugs, so there is a bit of disagreement on whether this warning option should be enabled by default and we have multiple settings in scripts/Makefile.extrawarn as well as individual subsystems. Older versions of clang only supported -Wno-initializer-overrides with the same meaning as gcc's -Woverride-init, though all supported versions now work with both. Because of this difference, an earlier cleanup of mine accidentally turned the clang warning off for W=1 builds and only left it on for W=2, while it's still enabled for gcc with W=1. There is also one driver that only turns the warning off for newer versions of gcc but not other compilers, and some but not all the Makefiles still use a cc-disable-warning conditional that is no longer needed with supported compilers here. Address all of the above by removing the special cases for clang and always turning the warning off unconditionally where it got in the way, using the syntax that is supported by both compilers.

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

2022-11-23T14:01:53Z

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.
