Subject: Re: [dpdk-dev] [dpdk-stable] [PATCH v2] igb_uio: prevent reset for a list of devices
Date: Tue, 7 Nov 2017 06:50:55 -0500 [thread overview]
Message-ID: <CAG2-Gkk1Z3ZE3XpyK_FQVLnQb9qeY3tYnny6n9x2m2E0MkFRyA@mail.gmail.com> (raw)
In-Reply-To: <2004961.P5XXAOnQC2@xps>
We still have an issue with this and PCI pass-through. If a guest is
restarted while using PCI pass-through and igb_uio issues a
pci_reset_function(), this causes the host to crash.
