Patches are now on the list to enable MTTCG for i386 and x86_64 guests. See v2 here:
https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg00237.html I'm hoping these patches will be in the next QEMU release. Regarding your last question: > For instance, has support for strong-on-weak memory consistency been added > into QEMU GIT at this point? Yes, TCG inserts the appropriate barriers around memory accesses since commit b32dc3370a ("tcg: Implement implicit ordering semantics", 2017-09-05) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1735049 Title: Need MTTCG support for x86 guests Status in QEMU: In Progress Bug description: MTTCG support is notably absent for x86_64 guests. The last Wiki update on MTTCG was back in 2015, and I am having some difficulty determining the current status of the underlying requirements to enable this feature on x86 hosts. For instance, has support for strong-on-weak memory consistency been added into QEMU GIT at this point? Thanks!
