Sets the `amdgpu.ppfeaturemask` kernel option. It can be used to enable the overdrive bit.
|
|
Default is `0xfffd7fff` as it is less likely to cause flicker issues. Setting it to
|
|
`0xffffffff` enables all features, but also can be unstable. See
|

[the kernel documentation](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/amd/include/amd_shared.h#n169)
