Who is maintaining the longrun(1) (should probably be longrun(8))
utility? The author is listed as Daniel Quinlan
<quinlan@transmeta.com>, but mail to that address bounces.
The longrun utility frobs the MSR on TransMeta processors to switch
between performance and economy modes.
On my laptop, currently running 2.4.21-pre5-ac1, I get the following
error:
# longrun -p
longrun: error reading /dev/cpu/0/cpuid: Invalid argument
# ls -l /dev/cpu/0
total 0
cr--r--r-- 1 root root 203, 0 Aug 30 2002 cpuid
crw------- 1 root root 10, 184 Aug 30 2002 microcode
crw------- 1 root root 202, 0 Aug 30 2002 msr
I've seen this the last couple 2.4.2x-pre versions, but I don't know
exactly when it stopped working. I assume somewhere along the line
the CPUID interface got reformatted. I'm pretty sure this kernel is
configured correctly:
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_X86_LONGRUN=y
CONFIG_X86_MSR=y
CONFIG_X86_CPUID=y
Help?
