[PATCH v2 0/2] Fix VFs resume errors

[Satyanarayana K V P]

Establish a connection between the PF and VF to ensure that VFs only
resume after the PF has resumed. Although the PF resumes, the VF reset
and provisioning occur in a separate worker process. VFs begin resuming
once the PF has completed its resumption.

However, some VFs might attempt to resume before the provisioning is
fully completed. In such cases, if a VF resume fails due to an MMIO
request, retry the operation up to GUC_RESET_VF_STATE_RETRY_MAX times.

Satyanarayana K V P (2):
  drm/xe/pf: Create a link between PF and VF devices
  drm/xe/vf: Retry sending MMIO request to GUC on timeout error
