The first patch of this series picks up an earlier v2 Ztso patch from Palmer, which can be found here: https://patchwork.kernel.org/project/qemu-devel/patch/20220917072635.11616-1-pal...@rivosinc.com/ 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. 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).
