[Qemu-devel] [PATCH v9 2/7] virtio-pmem: Add virtio pmem driver
...ed-by tag, but you can
take my acked-by + tested-by.
Acked-by: Jakub Staron <jstaron at google.com>
Tested-by: Jakub Staron <jstaron at google.com>
No kernel panics/stalls encountered during testing this patches (v9) with QEMU + xfstests.
Some CPU stalls encountered while testing with crosvm instead of QEMU with xfstests
(test generic/464) but no repro for QEMU, so the fault may be on the side of crosvm.
The dump for the crosvm/xfstests stall:
[ 2504.175276] rcu: INFO: rcu_sched detected stalls on CPUs/tasks:
[ 2504.176681] rcu: 0-...!: (1 GPs behind) idle=9b2/1/0x400000000000000...

Regression with "arm64: KVM: Skip MMIO insn after emulation" on 4.4 stable
Hello,
In my testing of crosvm[1] with Linux 4.4.175, I am observing failures
on a 'kevin' Chromebook (RK3399) device - the guest kernel does not
even get to the point of printing its first messages, and the host
seems to be spinning at 100% CPU in KVM_RUN.
I narrowed this down to the 4.4 stable backport of "arm64:...

Thank you for testing and confirming the results. I will add your tested &
acked-by in v10.

yes, looks like crosvm related as we did not see any of this in my and your
testing with Qemu.
