Subject: [kvm-unit-tests RFC 00/10] KVM: arm64: PMUv3 Event Counter Tests
Date: Fri, 6 Dec 2019 18:27:14 +0100 [thread overview]
Message-ID: <20191206172724.947-1-eric.auger@redhat.com> (raw)
This series implements tests exercising the PMUv3 event counters.
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.
