This set enables live migration for Intel QAT GEN4 SRIOV Virtual
Functions (VFs).
It is composed of 10 patches. Patch 1~6 refactor the original QAT PF
driver implementation which will be reused by the following patches.
Patch 7 introduces the logic to the QAT PF driver that allows to save
and restore the state of a bank (a QAT VF is a wrapper around banks) and
drain a ring pair. Patch 8 adds the QAT PF driver a set of interfaces to
allow to save and restore the state of a VF that will be called by the
module qat_vfio_pci which will be introduced in the last patch. Patch 9
implements the defined device interfaces. The last one adds a vfio pci
extension specific for QAT which intercepts the vfio device operations
for a QAT VF to allow live migration.
Here are the steps required to test the live migration of a QAT GEN4 VF:
1. Bind one or more QAT GEN4 VF devices to the module qat_vfio_pci.ko
2. Assign the VFs to the virtual machine and enable device live
migration
3. Run a workload using a QAT VF inside the VM, for example using qatlib
(https://github.com/intel/qatlib)
4. Migrate the VM from the source node to a destination node

2.18.2
Add logic to implement the interface for live migration defined in
qat/qat_mig_dev.h. This is specific for QAT GEN4 Virtual Functions
(VFs).
This introduces a migration data manager which is used to handle the
device state during migration. The manager ensures that the device state
is stored in a format that can be restored in the destination node.
The VF state is organized into a hierarchical structure that includes a
preamble, a general state section, a MISC bar section and an ETR bar
section. The latter contains the state of the 4 ring pairs contained on
a VF. Here is a graphical representation of the state:
preamble | general state section | leaf state
| MISC bar state section| leaf state
| ETR bar state section | bank0 state section | leaf state
| bank1 state section | leaf state
| bank2 state section | leaf state
| bank3 state section | leaf state
In addition to the implementation of the qat_migdev_ops interface and
the state manager framework, add a mutex in pfvf to avoid pf2vf messages
during migration.

2.18.2
Add vfio pci driver for Intel QAT VF devices.
This driver uses vfio_pci_core to register to the VFIO subsystem. It
acts as a vfio agent and interacts with the QAT PF driver to implement
VF live migration.

2.18.2
Move and rename ADF_4XXX_PF2VM_OFFSET and ADF_4XXX_VM2PF_OFFSET to
ADF_GEN4_PF2VM_OFFSET and ADF_GEN4_VM2PF_OFFSET respectively.
These definitions are moved from adf_gen4_pfvf.c to adf_gen4_hw_data.h
as they are specific to GEN4 and not just to qat_4xxx.
This change is made in anticipation of their use in live migration.
This does not introduce any functional change.

Move the code that implements VF version compatibility on the PF side to
a separate function so that it can be reused when doing VM live
migration.

From: Giovanni Cabiddu <[email protected]>
As the common hw_data files are growing and the adf_hw_csr_ops is going
to be extended with new operations, move all logic related to ring CSRs
to the newly created adf_gen[2|4]_hw_csr_data.[c|h] files.
This does not introduce any functional change.
