Title:
gicv2-mmio in ubuntu_kvm_unit_tests failed on X ARM64 Moonshot
Status in ubuntu-kernel-tests:
New
Status in linux package in Ubuntu:
Confirmed
Bug description:
This test passed with X-HWE on ARM64 Moonshot:
TESTNAME=gicv2-mmio TIMEOUT=90s ACCEL= ./arm/run arm/gic.flat -smp
$((($MAX_SMP < 8)?$MAX_SMP:8)) -machine gic-version=2 -append 'mmio'
PASS gicv2-mmio (17 tests, 1 skipped)
So this feels like a kernel issue to me.
