Modified files:
sys/dev/acpica acpi_perf.c
sys/kern kern_cpu.c
Log:
Add support for the CPUFREQ_FLAG_INFO_ONLY flag. Devices that report this
are not added to the list(s) of available settings. However, other drivers
can call the CPUFREQ_DRV_SETTINGS() method on those devices directly to
get info about available settings.
Update the acpi_perf(4) driver to use this flag in the presence of
"functional fixed hardware." Thus, future drivers like Powernow can
query acpi_perf for platform info but perform frequency transitions
themselves.
