Re: [coreboot] Change in coreboot[master]: Asus F2A85-M: Activate IOMMU support

[David Hubbard]

Hi all,

To answer http://review.coreboot.org/3517 about what the vendor BIOS does
for the IOMMU, here are my kernel logs (with the IOMMU enabled)

Please note:
Command line: ... iommu=pt

I had to do that to work around (more like, bury my head in the sand) the
problem with the on-board RTL8111/8168F, which trips over the IOMMU when
utilization gets near 100% gigabit speed. I put the details on kernel
bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=55841
