While trying to debug a GIC ITS failure I saw some guest errors that
had poor formatting as well as leaving me confused as to what failed.
As most of the checks aren't possible without a valid dte split that
check apart and then check the other conditions in steps. This avoids
us relying on undefined data.
I still get a failure with the current kvm-unit-tests but at least I
know (partially) why now:
Exception return from AArch64 EL1 to AArch64 EL1 PC 0x40080588
PASS: gicv3: its-trigger: inv/invall: dev2/eventid=20 now triggers an LPI
ITS: MAPD devid=2 size = 0x8 itt=0x40430000 valid=0
INT dev_id=2 event_id=20
process_its_cmd: invalid command attributes: invalid dte: 0 for 2 (MEM_TX: 0)
PASS: gicv3: its-trigger: mapd valid=false: no LPI after device unmap
SUMMARY: 6 tests, 1 unexpected failures
