hw/intc: clean-up error reporting for failed ITS cmd
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 Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 20211112170454.3158925-1-alex.bennee@linaro.org Cc: Shashi Mallela <shashi.mallela@linaro.org> Cc: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
