Subject: drm/amdgpu: Flush TLB on all XCCs on GFX 12.1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0c9ad4728687f4e4c8cec290540a9dc0956d3243;p=thirdparty%2Fkernel%2Flinux.git

drm/amdgpu: Flush TLB on all XCCs on GFX 12.1

Currently, the driver code is flushing TLB on XCC 0 only.
Fix it by flushing on all XCCs within the partition.
