Jason's "Connect VFIO to IOMMUFD" introduces vfio iommufd compat mode. Under this mode, vfio_iommufd_bind() creates an access which has an unmap callback, which can be called immediately. This means mdev drivers may receive unmap requests before the mdev is opened. For now, most dma_unmap() callbacks are tolerant with such unmap requests, except for gvt-g and vfio-ap. This series tries to enhance the two drivers. This series is based on Jason's below branch. https://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd.git/log/?h=for-next (commit: 57f62422b6f0477afaddd2fc77a4bb9b94275f42) Cc: Tony Krowiak <akrowiak@xxxxxxxxxxxxx> Cc: Halil Pasic <pasic@xxxxxxxxxxxxx> Cc: Jason Herne <jjherne@xxxxxxxxxxxxx> Cc: Zhenyu Wang <zhenyuw@xxxxxxxxxxxxxxx> Cc: Zhi Wang <zhi.a.wang@xxxxxxxxx> Cc: Kevin Tian <kevin.tian@xxxxxxxxx> Regards, Yi Liu Matthew Rosato (1): vfio/ap: validate iova during dma_unmap and trigger irq disable Yi Liu (1): i915/gvt: Move kvmgt_protect_table_init() and gvt_cache_init() into init drivers/gpu/drm/i915/gvt/gvt.h | 2 ++ drivers/gpu/drm/i915/gvt/kvmgt.c | 7 ++----- drivers/gpu/drm/i915/gvt/vgpu.c | 2 ++ drivers/s390/crypto/vfio_ap_ops.c | 24 +++++++++++++++++++++++- 4 files changed, 29 insertions(+), 6 deletions(-) -- 2.34.1
