Re: [libvirt] [PATCH v1 0/3] Adding the 'ccf-assist' pSeries capability

Hi, This short series exposes, implements and documents a pSeries guest capability called Count Cache Flush Assist (ccf-assist), which was added in the Linux kernel since 5.1 and in QEMU since 4.0.0. The reason why this capability needs to exposed via Libvirt is because it is defaulted to 'off' in QEMU to not break migration compatibility in the Power 9 processor class. However, there is a performance gain in activating it, thus the user might want to choose less migration options for more power. More details can be found in the commit message of patch 1.
