Subject: drm/xe/pf: Extract helper to show which VFs are provisioned
X-Git-Tag: v7.2-rc1~141^2~27^2~62
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=67a5fb1f9ada7c3d8b7f571be86554968084a4b9;p=thirdparty%2Flinux.git

drm/xe/pf: Extract helper to show which VFs are provisioned

In upcoming patches we will want to show which VFs were already
provisioned with resources other than LMEM(VRAM). Convert code
from the LMEM reporting function into a more generic helper that
can handle both u32 and u64 resources and can report also PF.
