[PULL v2 32/61] pcie_sriov: Allow user to create SR-IOV device |
|
Date: |
Tue, 23 Jul 2024 06:58:05 -0400 |
From: Akihiko Odaki <akihiko.odaki@daynix.com>
A user can create a SR-IOV device by specifying the PF with the
sriov-pf property of the VFs. The VFs must be added before the PF.
A user-creatable VF must have PCIDeviceClass::sriov_vf_user_creatable
set. Such a VF cannot refer to the PF because it is created before the
PF.
A PF that user-creatable VFs can be attached calls
pcie_sriov_pf_init_from_user_created_vfs() during realization and
pcie_sriov_pf_exit() when exiting.
