------- Comment From mranw...@us.ibm.com 2019-01-11 01:58 EDT------- I talked to Michael Roth on this. It looks like everything is there for spectre mitigation but there's two patches to allow power 8 guests to use cap_cfpc=workaround:
072f416a53: target/ppc: Don't require private l1d cache on POWER8 for cap_ppc_safe_cache b2540203bd: ppc/spapr_caps: Don't disable cap_cfpc on POWER8 by default Looks like the first one also pre-reqs: 8fea704 target/ppc: Factor out the parsing in kvmppc_get_cpu_characteristics() Suraj - anything else needed or you suggest there? Finally, this is, as Michael said, cosmetic, but if you wanted you can pull it in (it's not necessary): 8c5909c419 ppc/spapr-caps: Change migration macro to take full spapr-cap name -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765364 Title: Backport spectre/meltdown fixes on qemu for ppc64 into 16.04 and possibly 14.04 LTS releases To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1765364/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
