Resource virtualization unit (RVU) on Marvell's OcteonTX2 SOC supports
multiple PCIe SRIOV physical functions (PFs) and virtual functions (VFs).
PF0 is called administrative / admin function (AF) and has privilege access
to registers to provision different RVU functional blocks to each of
PF/VF.
This admin function (AF) driver acts as a configuration / administrative
software which provisions functional blocks to a PF/VF on demand for them
to work as one of the following
- A basic network controller (i.e NIC).
- NIC with packet filtering, shaping and scheduling capabilities.
- A crypto device.
- A combination of above etc.
PF/VFs communicate with admin function via a shared memory region.
This patch series adds logic for the following
- RVU AF driver with functional blocks provisioning support
- Mailbox infrastructure for communication between AF and PFs.
- CGX driver which provides information about physcial network
interfaces which AF processes and forwards required info to
PF/VF drivers.
This is the first set of patches out of 70 odd patches.
Note: This driver neither receives any data nor processes it i.e no I/O,
just does the hardware configuration.
Changes from v1:
1 Merged RVU admin function and CGX drivers into a single module
- Suggested by Arnd Bergmann
2 Pulled mbox communication APIs into a separate module to remove
admin function driver dependency in a VM where AF is not attached.
- Suggested by Arnd Bergmann
