Subject: [PATCH v3 0/4] s390x: Fix IRB sense data
Date: Wed, 16 Jun 2021 03:47:45 +0200 [thread overview]
Message-ID: <20210616014749.2460133-1-farman@linux.ibm.com> (raw)
Conny, et al,
Here is a (significantly larger) set of patches to address
the problem with building passsthrough sense data in an IRB,
using a subchannel-specific callback.
The first three patches are primarily code refactoring.
But, since patch 3 doesn't implement the callback for
vfio-ccw subchannels, it fixes the problem encountered
with "dasdfmt -M quick" failing to run correctly in the
guest because we no longer fill out the other stuff in
the IRB associated with the sense data.
Patch 4 implements that for vfio-ccw.
v2->v3:
- [EF] Drop Fixes tag
- [CH] Implement a callback for the IRB sense data
- [CH] Copy IRB.ESW from passthrough hardware
- [CH] Only put sense in IRB.ECW if passthrough device did
v1->v2:
- [MR] Add Fixes: tags
- [CH] Reinstate the memcpy(sch->sense_data, irb.ecw) in vfio_ccw
- [CH] Look at IRB.SCSW.E before copying sense into guest IRB
v2: https://lore.kernel.org/qemu-devel/20210611202151.615410-1-farman@linux.ibm.com/
v1: https://lore.kernel.org/qemu-devel/20210610202011.391029-1-farman@linux.ibm.com/
