It tests both the 32-bit and 64-bit versions. Overflow interrupts also are checked. Those tests only are written for arm64. It allowed to reveal some issues related to SW_INCR implementation (esp. related to 64-bit implementation), some problems related to 32-bit <-> 64-bit transitions and consistency of enabled states of odd and event counters. Overflow interrupt testing relies of one patch from Andre ("arm: gic: Provide per-IRQ helper functions") to enable the PPI 23, coming from "arm: gic: Test SPIs and interrupt groups" (https://patchwork.kernel.org/cover/11234975/). Drew kindly provided "arm64: Provide read/write_sysreg_s". All PMU tests can be launched with: ./run_tests.sh -g pmu Tests also can be launched individually. For example: ./arm-run arm/pmu.flat -append 'chained-sw-incr' With KVM: - chain-promotion and chained-sw-incr are known to be failing. - Problems were reported upstream. With TCG: - pmu-event-introspection is failing due to missing required events (we may remove this from TCG actually) - chained-sw-incr also fails. I haven't investigated yet. The series can be found at: https://github.com/eauger/kut/tree/pmu_event_counters_v1 History: v1 -> v2: - Use new report() proto - Style cleanup - do not warn about ARM spec recommendations - add a comment about PMCEID0/1 splits Andre Przywara (1): arm: gic: Provide per-IRQ helper functions Andrew Jones (1): arm64: Provide read/write_sysreg_s Eric Auger (8): arm: pmu: Let pmu tests take a sub-test parameter arm: pmu: Add a pmu struct arm: pmu: Check Required Event Support arm: pmu: Basic event counter Tests arm: pmu: Test chained counter arm: pmu: test 32-bit <-> 64-bit transitions arm/arm64: gic: Introduce setup_irq() helper arm: pmu: Test overflow interrupts arm/gic.c | 24 +- arm/pmu.c | 783 ++++++++++++++++++++++++++++++++++++++++- arm/unittests.cfg | 55 ++- lib/arm/asm/gic-v3.h | 2 + lib/arm/asm/gic.h | 12 + lib/arm/gic.c | 101 ++++++ lib/arm64/asm/sysreg.h | 11 + 7 files changed, 950 insertions(+), 38 deletions(-) --=20 2.20.1
