Title:
disable Intel DMA remapping by default
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Jammy:
In Progress
Bug description:
[Impact]
It seems that enabling Intel IOMMU can cause some weird gfx problems, see for
example:
https://bugs.launchpad.net/bugs/1971146
https://bugs.launchpad.net/bugs/1965882
[Test case]
We don't have any specific test case, only other bug reports that
tracked down the origin of the issue as being introduced when
CONFIG_INTEL_IOMMU_DEFAULT_ON has been enabled by default.
[Fix]
Revert "UBUNTU: [Config] enable Intel DMA remapping options by
default"
[Regression potential]
DMA remapping device not present at boot by default, users that
require this feature will need to specifically add intel_iommu=on to
the kernel boot parameters to enable it.
