[PATCH 1/2] cpufreq, powernow: enable/disable core performance boost for all cpus in policy
Currently, enable/disable turbo mode on AMD is broken: $ xenpm enable-turbo-mode 0 <-- works and proper CPU MSR bit is set $ xenpm enable-turbo-mode 1 <-- silently broken, MSR bit not set Since ->turbo is per policy, when user requests to enable/disable turbo mode, we need to set the bit in all of the ->cpus that this policy affects. --- xen/arch/x86/acpi/cpufreq/powernow.c | 2
