With the development of arm gic architecture, we think it will be useful
to add some performance test in kut to measure the cost of interrupts.
In this series, we add GICv4.1 support for ipi latency test and
implement LPI/vtimer latency test.
Jingyi Wang (6):
arm64: microbench: get correct ipi recieved num
arm64: microbench: Use the funcions for ipi test as the general
functions for gic(ipi/lpi/timer) test.
arm64: microbench: gic: Add gicv4.1 support for ipi latency test.
arm64: its: Handle its command queue wrapping
arm64: microbench: its: Add LPI latency test.
arm64: microbench: Add vtimer latency test
