Thanks for respinning the series, I left some comments. I'd really like to get this feature picked up, hope you have cycles to work on it soon. FWIW, we're considering adding a new vCPU feature flag to deprecate all the ugliness of the old PMUv3 UAPI. I'm tempted to say that the FIXED_COUNTERS_ONLY feature is conditioned on the new feature flag... https://lore.kernel.org/kvmarm/[email protected]/ Thanks, Oliver
