Subject: [PATCH v1 0/1] Don't split flush for amd_iommu_domain_flush_all()
Date: Tue, 14 Apr 2026 21:06:25 +0000 [thread overview]
Message-ID: <20260414210626.2097722-1-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
