[PATCH 0/2] iommu/vt-d: Fix posted vCPU vs. posted MSI bugs
From: Sean Christopherson
Date: Fri Mar 14 2025 - 22:51:45 EST
Fix bugs where using posted MSIs will clobber IRTEs that are configured to
post IRQs to a vCPU, and where undoing vCPU posting fails to put the IRTE
backing into posted MSI mode.
Sean Christopherson (2):
iommu/vt-d: Put IRTE back into posted MSI mode if vCPU posting is
disabled
iommu/vt-d: Don't clobber posted vCPU IRTE when host IRQ affinity
changes
