Subject: [pve-devel] [PATCH pve-kernel] d/rules: kconfig: do not enable intel_iommu by default
Date: Fri, 13 May 2022 10:57:39 +0200 [thread overview]
Message-ID: <20220513085739.545309-1-s.ivanov@proxmox.com> (raw)
enabling this causes quite a few issues with older hardware
(hp g8, and the like) - and most of our guides do call for enabling it
where needed (pci passthrough).
the setting was off in the 5.13 series.
following reports of disabling intel_iommu explicitly fixing the
issues in our community forum:

Signed-off-by: Stoiko Ivanov <s.ivanov@proxmox.com>

tested by installing on a HP G8 (and starting a minimal VM and running
stress-ng -d 2 for a minute), and on 2 VMs
alternatively we could document this in the 7.2 release notes and ask
users of problematic hardware to set this explicitly
