Subject: drm/amdgpu: Support 57bit fault address for GFX 12.1.0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8efa1a11e160dbe500b52ce21bf0c3f585e64206;p=thirdparty%2Fkernel%2Flinux.git

drm/amdgpu: Support 57bit fault address for GFX 12.1.0

The gmc fault virtual address is up to 57bit for 5 level page table,
this also works with 48bit virtual address for 4 level page table.
