Subject: [PATCH QEMU HCI-8.1 v2 00/24] vfio: support qemu-update with passed through GPU's and vGPU's #VSTOR-103860
Date: Tue, 13 Oct 2026 18:28:04 +0300 [thread overview]
Message-ID: <20261013-vfio_v1-v2-0-433455c0a294@virtuozzo.com> (raw)
v1 -> v2:
Fixes of the issues found by Sashiko AI review.
- Patch (NEW) 10: ("migration: vmstate_save_state_v: fix double error_setg"):
upstream fix for patch 9
- Patch 10 -> 11 ("migration: yank: Move register instance earlier"): don't
leak the yank instance when the start fails synchronously (next migrate
would abort), don't unregister it on a resume
- Patch (NEW) 17: migration/cpr: add cpr_is_in_progress()
- Patch 16 -> 18 ("vfio/migration: don't migrate device state during CPR"):
VM state change handlers are gated on cpr_is_in_progress() instead of
the mode alone
- Patch 17 -> 19 ("vfio/listener: skip dirty page tracking during CPR"):
only the start is skipped, the stop stays unconditional
- Patch 18 ("VZ: physmem: align fd-backed RAM like anonymous RAM"): dropped,
not needed with the kernel-side memory preservation
- Patch (NEW) 20: ("VZ: vfio/cpr: don't close KVM on cpr-exec"): a cpr-exec
that gives up left the VM without KVM
- Patch (NEW) 22: ("VZ: migration/cpr-exec: take the vhost-net devices back if
exec fails")
- Patch 20 -> 23 ("VZ: vfio/region: preserve BAR mappings across cpr-exec"):
drop the saved mappings at region exit (hot-unplug blocked all later
cpr-execs), check them like ram_block_add() does, block cpr-transfer for
devices with mmapped regions
