Title:
disable Intel DMA remapping by default
A user has reported extensive performance issues with a Lenovo Thinkpad
X1 Extreme Gen 2 laptop computer, in bug 1973434. The user reports video
playback hangs, browser hangs and virtual machines hanging.
Their dmesg indicates the system has 2x IOMMUs and there are 25 groups
being configured.
A user has ran into a storage performance issue, and it has been traced
back to CONFIG_INTEL_IOMMU_DEFAULT_ON being enabled.
They have a Dell XtremIO FC storage server, running VMWare ESXi 7.0U3,
with 4x pvscsi controllers (2 LUNs per controller), running a single
large LV with 8-way 1MB stripe.
