Subject: drm/amdgpu: Move scheduler init to after XGMI is ready
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 5fd8518d187ed03403a4d4f7f56f52c00b11c148
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
Before we initialize schedulers we must know which reset
domain are we in - for single device there iis a single
domain per device and so single wq per device. For XGMI
the reset domain spans the entire XGMI hive and so the
reset wq is per hive.
