Subject: [PATCH v1 3/3] iommu/amd: Optimize the IOMMU queue flush
After reducing the amount of MMIO performed by the IOMMU during
operation,
perf data shows that flushing the TLB for all protection domains during
DMA unmapping is a performance issue. It is not necessary to flush the

perf data shows that flushing the TLB for all protection domains during
DMA unmapping is a performance issue. It is not necessary to flush the
TLBs for all protection domains, only the protection domains associated
