[PATCH v1 0/3] ppc: LPCR synchronisation fixes

Posted by Nicholas Piggin 2 years, 10 months ago

These incoherencies have been around for a while, but they've started
to get noticed now because recent Linux guests crash when LPCR[AIL] is
not set correctly (scv requires it). This series fixes at least AIL and
DPFD incoherency between KVM and QEMU, and between different vCPUs.

Thanks,
Nick
