Subject: drm/amdkfd: Print bdf in peer map failure message
Git-commit: 0c41b9b561dbd81dd3955c4c8b59d55244a80100
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Print alloc node, peer node and memory domain when peer map fails. This
is more useful
v2: use dev_err instead of pr_err
use bdf for identify peer gpu
