Subject: [Qemu-devel] [PATCH] vfio/pci-quirks: Exclude non-ioport BAR from NVIDIA quirk
Date: Wed, 05 Apr 2017 14:34:02 -0600 [thread overview]
Message-ID: <20170405203345.12539.45427.stgit@gimli.home> (raw)
The NVIDIA BAR5 quirk is targeting an ioport BAR. Some older devices
have a BAR5 which is not ioport and can induce a segfault here. Test
the BAR type to skip these devices.
