The first patch of this series picks up an earlier v2 Ztso patch from Palmer,
which can be found here:

This patch did not apply cleanly but the necessary changes were trivial.
There was a request to extend the commit message, which is part of the
posted patch of this series. As this patch was reviewed a year ago,
I believe it could be merged.
The second patch simply exposes Ztso via hwprobe.
It's also worth mentioning that the second patch relies on:
"[PATCH 0/2] linux-user/riscv: Sync hwprobe keys with kernel"
To be applied beforehand.
Indeed! Therefore, the end of the cover letter contains the following paragraph:
"""
This series is based on today's riscv-to-apply.next with my other series
that adds the new hwprobe keys
(https://lists.gnu.org/archive/html/qemu-devel/2024-02/msg01293.html).
"""
I guess it's also worth mentioning that I didn't pay enough attention to the
cover letter :skull:
Thanks,
Daniel
To ease reviewing and testing for others, I've also created a remote
branch on GitHub.
Thanks for reviewing!
Thanks,
Daniel
Relevant in this context might be also, that Richard's patch to improve
TCG's memory barrier selection depending on host and guest memory ordering
landed in June 2023:
https://lore.kernel.org/all/a313b36b-dcc1-f812-ccbd-afed1cbd5...@linaro.org/T/
The first patch was already sent as part of an RFC series for Ssdtso:
https://lists.nongnu.org/archive/html/qemu-devel/2023-11/msg02962.html
Since I don't want to keep this patch until the ratification of Ssdtso,
I would like to get this merged independent of Ssdtso.
This series is based on today's riscv-to-apply.next with my other series
that adds the new hwprobe keys
(https://lists.gnu.org/archive/html/qemu-devel/2024-02/msg01293.html).
