In case of VFIO the interrupts are not configured at probe time, but later by userspace request 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. 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 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 bus/fsl-mc: Add a new version for dprc_get_obj_region command drivers/bus/fsl-mc/dprc-driver.c | 181 ++++++++++++++++---------- 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 | 37 +++++- 7 files changed, 348 insertions(+), 125 deletions(-) -- 2.17.1
