The vfio-mc bus driver needs some additional services to be exported by the
mc-bus driver like:
- a way to reset the DPRC container
- driver_override support
- functions to setup/tear down a DPRC
- functions for allocating the pool of interrupts. In case of VFIO the
interrupts are not configured at probe time, but later by userspace
request
v4 -> v5
- dprc_celanup should not fail
v3 -> v4
- Rebased on the latest kernel.
- Exported a dprc_remove function
v2 -> v3
- Add a new version for dprc_get_obj_region
- Export the cacheability bus specific bits defines
v1 -> v2
- Remove driver_override propagation through various functions
- Cache the DPRC API version
The patches are related with "vfio/fsl-mc: VFIO support for FSL-MC
devices" patches, but the series were split because they are targeting
different subsystems. However, the mc-bus patches may suffer changes
when addressing the VFIO review comments.
The patches do not address the comment regarding moving driver_override
in the core code. I prefer not to tie these patches on that change and
address that separately.
