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
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.
Bharat Bhushan (3):
bus/fsl-mc: add support for 'driver_override' in the mc-bus
bus/fsl-mc: Add dprc-reset-container support
bus/fsl-mc: Extend ICID size from 16bit to 32bit
Diana Craciun (9):
bus/fsl-mc: Do no longer export the total number of irqs outside
dprc_scan_objects
bus/fsl-mc: Add a new parameter to dprc_scan_objects function
bus/fsl-mc: Set the QMAN/BMAN region flags
bus/fsl-mc: Cache the DPRC API version
bus/fsl-mc: Export a dprc scan function to be used by multiple
entities
bus/fsl-mc: Export a cleanup function for DPRC
bus/fsl-mc: Add a container setup function
bus/fsl_mc: Do not rely on caller to provide non NULL mc_io
bus/fsl-mc: Export IRQ pool handling functions to be used by VFIO
