To run correctly, each Virtual Function must be provisioned with some chunk of shared hardware or firmware resources (like GGTT, device memory, GuC doorbell IDs, GuC context IDs) and scheduling parameters (execution quantum or preemption timeout). All resources assigned to VFs must be excluded from the PF driver use and may require some additional preparation steps (like setup of the LMTT or update of the GGTT PTE). Those provisioning details must be then sent to the GuC firmware as most of those details will be shared later with the VF drivers during their boot. Add basic functions to provision VFs with all hardware resources or scheduling parameters. We will use them shortly in upcoming patches either in manual provisioning over debugfs, exposed to the advanced users, or automatic provisioning done by PF driver during VFs enabling.
