Hi Greg, Diana has a vfio bus driver for fsl-mc devices queued up in my tree as well. After a linux-next build failure due to our branches being applied in the wrong order, Stephen advised that the proper way to handle this is to merge a shared branch with this series. Do you have a pull request imminent with this series or if not, would you mind pushing such a branch? Thanks, Alex

Thanks, This should all now be in Linus's tree, so I don't think you need any shared branch anymore :) thanks, greg k-h
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. 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 (10): 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 dprc_scan/dprc_remove functions 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 bus/fsl-mc: Add a new version for dprc_get_obj_region command drivers/bus/fsl-mc/dprc-driver.c | 190 ++++++++++++++++---------- drivers/bus/fsl-mc/dprc.c | 141 +++++++++++++++---- drivers/bus/fsl-mc/fsl-mc-allocator.c | 12 +- drivers/bus/fsl-mc/fsl-mc-bus.c | 64 ++++++++- drivers/bus/fsl-mc/fsl-mc-private.h | 31 ++--- drivers/bus/fsl-mc/mc-io.c | 7 +- include/linux/fsl/mc.h | 41 +++++- 7 files changed, 359 insertions(+), 127 deletions(-)
