[Xen-devel] [PATCH 0/2] iommu: fixes for interrupt remapping enabling

Posted by Roger Pau Monne 4 years, 6 months ago

Hello,

The following series contain two fixes for issues found when enabling
interrupt remapping and the IO-APIC already has unmasked pins. While I'm
not aware of any system malfunctioning (apart from reporting IOMMU
interrupt remapping faults) I think it would be nice to have those in
4.13.

Thanks, Roger.
