[kvm-unit-tests PATCH v2 0/8] arm/arm64: Add IPI/LPI/vtimer latency test
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. This series of patches has been tested on GICv4.1 supported hardware. * From v1: - Fix spelling mistake - Use the existing interface to inject hw sgi to simply the logic - Add two separate patches to limit the running times and time cost of each individual micro-bench test Jingyi Wang (8): arm64: microbench: get correct ipi received 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: Allow each test to specify its running times arm64: microbench: Add time limit for each individual test arm64: microbench: Add vtimer latency test arm/micro-bench.c | 218 +++-- lib/arm/asm/gic-v3.h | 3 + lib/arm/asm/gic.h | 1 + lib/arm64/gic-v3-its-cmd.c | 3 +- 4 files changed, 189 insertions(+), 36 deletions(-) -- 2.19.1 ___ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
