Subject: [PATCH v5 03/20] vfio/pci: Export vfio_pci_dma_buf_move for vfio-pci module
Date: Tue, 14 Jul 2026 08:14:48 -0700 [thread overview]
Message-ID: <20260714151505.3466855-4-vipinsh@google.com> (raw)
In-Reply-To: <20260714151505.3466855-1-vipinsh@google.com>
VFIO Live update during freeze needs to reset the device before handing
over to next kernel.
Export DMA revoke function which VFIO Live Update will call in its
freeze before reset so that P2P DMA doesn't error out or cause some
other issue.
