[kvm-unit-tests PATCH v3 0/3] GIC ITS tests

[Alex Bennée]

Hi,

Sorry this has been sitting in my tree so long. The changes are fairly
minor from v2. I no longer split the tests up into TCG and KVM
versions and instead just ensure that ERRATA_FORCE is always set when
run under TCG.

Alex Bennée (3):
  arm64: remove invalid check from its-trigger test
  arm64: enable its-migration tests for TCG
  arch-run: do not process ERRATA when running under TCG

[kvm-unit-tests PATCH v3 1/3] arm64: remove invalid check from its-trigger test

[Alex Bennée]

While an IRQ is not "guaranteed to be visible until an appropriate
invalidation" it doesn't stop the actual implementation delivering it
earlier if it wants to. This is the case for QEMU's TCG and as tests
should only be checking architectural compliance this check is
invalid.

With the support for TCG emulated GIC we can also test these now.

[kvm-unit-tests PATCH v3 3/3] arch-run: do not process ERRATA when running under TCG

[Alex Bennée]

All the errata checking looks at the current host kernel version. For
TCG runs this is entirely irrelevant as the host kernel has no impact
on the behaviour of the guest. In fact we should set ERRATA_FORCE to
ensure we run those tests as QEMU doesn't attempt to model
non-confirming architectures.

Hi Alex,

Thanks for this. I've applied to arm/queue, but I see that

FAIL: gicv3: its-trigger: inv/invall: dev2/eventid=20 pending LPI is received

consistently fails for me. Is that expected? Does it work for you?

Thanks,
drew

doh - looks like I cocked up the merge conflict...

Did it fail for TCG or for KVM (or both)?

Just TCG, which was why I was wondering if it was expected. I've never run
these tests with TCG before.

Hmm I think expecting the IRQ at all is broken so I think I should
delete the whole pending test.

Actually I think the problem was with a regression in the TCG ITS
support (now fixed in master). So I believe as of v3 everything is
correct (and v4 should be ignored).

Are you happy to apply this series or do you want me to repost it as v5?

No need to repost. I'll retest v3 with latest QEMU.

Gentle ping, I'm trying to clear this off my internal JIRA so let me

Sorry Alex! I've been juggling too many balls lately and completely
dropped this one. I'll rebase arm/queue now and run it through some
sanity tests. If all it good, I'll do the MR right away.
