Subject: [PATCH v2 0/1] Don't split flush for amd_iommu_domain_flush_all()
Date: Thu, 28 May 2026 22:31:46 +0000	[thread overview]
Message-ID: <20260528223147.750229-1-wnliu@google.com> (raw)

This patch is a respin of Josef Bacik's original work[1] to fix the
performance issues and soft lockups in the AMD IOMMU driver when running
within a VM. I am taking over the respin as Josef currently has limited
time for this
