Subject: [PATCH RFC 0/2] Support Hyper-V vPCI controller reset method
Date: Fri, 24 Jul 2026 16:08:41 -0700 [thread overview]
Message-ID: <20260724230844.3259741-1-wei.liu@kernel.org> (raw)
From: Wei Liu <wei.liu@kernel.org>
Hi,
On Azure, there are devices that don't support function level or PM
reset. They can only be reset by sending a VMBus message to the host.
This series is RFC because I modelled the reset method at the controller
level. If there is a better way to do it, I'm happy to change the code.
Thanks,
Wei
