Not sure if the page colors are interesting, but it'd be good to have
the power management features back.
The power management features are broken due to a problem with the
bitmask_snprintf() buffer. Apply the attached patch (I've submitted
as part of a much larger patch to cpuctl in PR bin/38722)
Are you going to commit this or is there a problem with this patch?
Actually, I think this PR was addressed a while ago when Christos
checked in some related changes for a number of cpuctl-related PRs. The
fix for this particular problem was originally provided by me in
PR/38723 (NOT 38722) and committed by christos@ in rev 1.6 of
Is there still something not working (or not working correctly) in this
area? If still broken I'll be more than happy to follow up.
Yes. The ci_feature_flags merges the feature bits of several cpuid
