The implementation\nuses the vEVENTQ support provided by the IOMMUFD subsystem in the kernel.\n\nI have tested this on a Grace platform using some hacks to generate\nevents. Further testing and feedback are welcome.\n---\n\n\nNicolin Chen (2):\n backends/iommufd: Introduce iommufd_backend_alloc_veventq\n hw/arm/smmuv3-accel: Allocate vEVENTQ for accelerated SMMUv3 devices\n\nShameer Kolothum (3):\n hw/arm/smmuv3-accel: Add viommu free helper\n hw/arm/smmuv3: Introduce a helper function for event propagation\n hw/arm/smmuv3-accel: Read and propagate host vIOMMU events\n\n hw/arm/smmuv3-accel.h | 6 ++\n hw/arm/smmuv3-internal.h | 4 ++\n include/system/iommufd.h | 14 ++++\n backends/iommufd.c | 31 +++++++++\n hw/arm/smmuv3-accel.c | 146 ++++++++++++++++++++++++++++++++++++---\n hw/arm/smmuv3.c | 26 +++++--\n backends/trace-events | 1 +\n hw/arm/trace-events | 2 +-\n 8 files changed, 215 insertions(+), 15 deletions(-)"}
