Subject: [PATCH v5 0/7] MSI-X support with qemu in stubdomain, and other related changes
Date: Wed, 13 Mar 2024 16:16:05 +0100 [thread overview]
Message-ID: <cover.afa2d89161590f5193dd6bfd340c5e9347877aae.1710342968.git-series.marmarek@invisiblethingslab.com> (raw)
This series includes changes to make MSI-X working with Linux stubdomain and
especially Intel Wifi 6 AX210 card. This takes care of remaining reasons for
QEMU to access /dev/mem, but also the Intel Wifi card violating spec by putting
some registers on the same page as the MSI-X table.
Besides the stubdomain case (of which I care more), this is also necessary for
PCI-passthrough to work with lockdown enabled in dom0 (when QEMU runs in dom0).
See individual patches for details.
This series include also tests for MSI-X using new approach (by preventing QEMU
access to /dev/mem). But for it to work, it needs QEMU change that
makes use of the changes introduced here. It can be seen at
https://github.com/marmarek/qemu/commits/msix
Here is the pipeline that used the QEMU fork above:

Marek Marczykowski-Górecki (7):
x86/msi: passthrough all MSI-X vector ctrl writes to device model
x86/msi: Extend per-domain/device warning mechanism
x86/hvm: Allow access to registers on the same page as MSI-X table
automation: prevent QEMU access to /dev/mem in PCI passthrough tests
automation: switch to a wifi card on ADL system
[DO NOT APPLY] switch to qemu fork
[DO NOT APPLY] switch to alternative artifact repo
