Subject: [PATCH v3 00/11] s390/vfio-ccw rework
Date: Thu, 30 Jun 2022 22:36:36 +0200	[thread overview]
Message-ID: <20220630203647.2529815-1-farman@linux.ibm.com> (raw)

Here's an updated pass through the first chunk of vfio-ccw rework.

As with v2, this is all internal to vfio-ccw, with the exception of
the removal of mdev_uuid from include/linux/mdev.h in patch 1.

There is one conflict with the vfio-next branch [2], on patch 6.

The remainder of the work that Jason Gunthorpe originally started [1]
in this space remains for a future day.

v2-v3:
 - [KW, MR, JG] Added r-b's (Thank You!)
 - Patch 7 (new):
   - [MR] Add better debug to fsm_notoper
 - Patch 8:
   - [MR] Call fsm_notoper for the OPEN event from STANDBY state
   - [EF] Drop FSM state=STANDBY in vfio_ccw_sch_probe()
     (it is handled in FSM, and was dropped by patch 10)
 - Patch 9:
   - [MR] Call fsm_close for the CLOSE event from STANDBY state
v2: https://lore.kernel.org/r/20220615203318.3830778-1-farman@linux.ibm.com/
v1: https://lore.kernel.org/r/20220602171948.2790690-1-farman@linux.ibm.com/
