If they are not the same issue, QE would like to report new one, thanks.

Comment 2 Greg Kurz 2021-05-21 16:16:06 UTC

This isn't a regression of reset-all in SLOF actually. This is a
regression in QEMU. You can check that system_reset in the QEMU
monitor doesn't work any better.

I've posted a fix to qemu-devel:

https://patchew.org/QEMU/20210521160735.1901914-1-groug@kaod.org/

You can try out this brew build:

The auto test of above scratch build has passed
Hi Greg,
Could you please set DTM for this bug later ? Thanks a lot.

Cool.

The fix is now in David's ppc-for-6.1 tree:

https://gitlab.com/dgibson/qemu/-/commit/0bec0e30e074b183332d448c47dc29e00606cdc2

Assuming that this reaches upstream soon enough so that I can POST before 06/07,
setting DTM to 16.

Comment 5 David Gibson 2021-05-27 05:18:44 UTC

Greg, can you remind me to send another PR next week so that you get this merged in time.

Comment 8 Min Deng 2021-06-15 02:12:51 UTC

I will handle it soon with above build. Set needinfo myself.

Comment 9 Zhenyu Zhang 2021-06-15 08:28:43 UTC

Set Verified:Tested,SanityOnly as gating/tier1 test pass.

Comment 12 Min Deng 2021-06-21 01:48:46 UTC

Verified the bug on build
qemu-kvm-6.0.0-19.module+el8.5.0+11385+6e7d542e.ppc64le
SLOF-20210217-1.scrmod+el8.5.0+11436+46173b38.noarch
