We currently miss a bunch of register resets in the device reset
|
|
function. This sometimes prevents the guest from rebooting after
|
|
a system_reset (with virtio-blk-pci). For instance, we may get
|
|
the following errors:
|
|
|
|
invalid STE
|
|
smmuv3-iommu-memory-region-0-0 translation failed for iova=0x13a9d2000(SMMU_EVT_C_BAD_STE)
|
|
Invalid read at addr 0x13A9D2000, size 2, region '(null)', reason: rejected
|
|
invalid STE
