X-Git-Tag: v2.6.28-rc1~26^2~29^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=910dfae298f7b3dae0e9a52736182a3b0559ca35;p=pandora-kernel.git 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 Signed-off-by: Andi Kleen Signed-off-by: Len Brown --- Reading git-diff-tree failed
