Subject: Re: [RFC PATCH v3 13/20] vfio/pci: Track PCI recovery state
Date: Thu, 12 Nov 2026 14:35:46 +0000 [thread overview]
Message-ID: <sashiko-outbox-211349@kernel.org> (raw)
In-Reply-To: <20261112141632.918954-14-skolothumtho@nvidia.com>
> PCI error recovery spans several callbacks. Add state to track its
> progress so later patches can keep access blocked until recovery
> succeeds and leave it blocked if recovery fails.
>
> Add recovery flags, a sequence counter and saved PCI_COMMAND state.
> Initialize per-open state during open and clear it on close. Keep host
> recovery state separate so close does not lose an ongoing recovery that
> must prevent reopening.
>
> Signed-off-by: Shameer Kolothum <skolothumtho@nvidia.com>
