The total code coverage they give is: Overall coverage rate: lines......: 11.2% (59584 of 530123 lines) functions..: 15.0% (7436 of 49443 functions) branches...: 6.3% (19273 of 303933 branches) We already get pretty close to that with the machine_aarch64_virt tests which only does one full boot (~120s vs ~600s) of alpine. We expand the kernel+initrd boot (~8s) to test both GICs and also add an RNG device and a block device to generate a few IRQs and exercise the storage layer. With that we get to a coverage of: Overall coverage rate: lines......: 11.0% (58121 of 530123 lines) functions..: 14.9% (7343 of 49443 functions) branches...: 6.0% (18269 of 303933 branches) which I feel is close enough given the massive time saving.

It is described in the SMMU manual in "6.3.14 SMMU_GBPA". ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to be zero(Do not abort incoming transactions). Other fields have default values of Use Incoming. If UPDATE is not set, the write is ignored. This is the only permitted behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure) As this patch adds a new state to the SMMU (GBPA), it is added in a new subsection for forward migration compatibility. GBPA is only migrated if its value is different from the reset value. It does this to be backward migration compatible if SW didn't write the register.
