ACPI: cpufreq, processor: Detect old BIOS, not supporting CPU freq on a recent CPU.
On Intel CPUs it is rather common and a good hint that BIOSes which do provide _PPC func, but not the frequencies itself in _PSS function, are old and need to be updated for CPU freq support. Tell the user/vendor he has a BIOS/firmware problem. Make use of FW_BUG interface to give vendors and users the ability to automatically check with (or let linuxfirmwarekit do that): dmesg |grep "Firmware Bug" Signed-off-by: Thomas Renninger <trenn@suse.de> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
