I'm currently trying to run the MTE selftests on the FVP simulator (Base Model)[1], mainly to verify things are sane on the host before wiring up the KVM support in QEMU. However, I'm seeing some failures (the non-mte tests seemed all fine):
Are the MTE tests supposed to work on the FVP model? Something broken in my config? Anything I can debug?
I would expect them to work, they seemed happy when I was doing the async mode support IIRC and a quick spin with -next in qemu everything seems fine, I'm travelling so don't have the environment for models to hand right now.
Thanks; I think that points to some setup/config problem on my side, then :/ (I ran the selftests under QEMU's tcg emulation, and while it looks better, I still get timeouts for check_gcr_el1_cswitch and check_user_mem.)
...so these two tests are simply very slow; if I run them directly, they take longer than 45s, but eventually finish. So all seems good (in a slow way) on QEMU + tcg.
On the simulator, running check_gcr_el1_cswitch directly finishes successfully after several minutes as well; however, I get all the other failures in tests that I reported in my first mail even when I run them directly.
