Subject: cpufreq on Toshiba Portege M100 Laptop
Date: Thu, 12 Jul 2007 13:41:46 +0200 [thread overview]
Message-ID: <4696137A.1010701@nachtwindheim.de> (raw)
Hello,
this week I got a Toshiba Portege M100 Laptop. I installed Debian (sid) and everything was great.
I could see the P-States on powertop, which were 600MHz - 1200 MHz in 100MHz steps.
Then I upgraded the firmware of the Laptop and then it happend:
acpi-cpufreq: acpi_cpufreq_init
acpi-cpufreq: acpi_cpufreq_early_init
cpufreq-core: trying to register driver acpi-cpufreq
cpufreq-core: adding CPU 0
acpi-cpufreq: acpi_cpufreq_cpu_init
acpi-cpufreq: No P-States 1
cpufreq-core: initialization failed
cpufreq-core: no CPU initialized for driver acpi-cpufreq
cpufreq-core: unregistering CPU 0
That 1 in the line after "No P-States" is the value of perf->state_count from acpi_cpufreq_cpu_init(),
which I added to acpi-cpufreq to see whats wrong. I used the latest kernel-2.6.22-git2 via git.
Then I tryed cpeedstep-centrino with this result.
cpufreq-core: trying to register driver centrino
cpufreq-core: adding CPU 0
speedstep-centrino: No P-States
speedstep-centrino: speedstep-centrino: invalid ACPI data
speedstep-centrino: found "Intel(R) Pentium(R) M processor 1200MHz": max frequency: 1200000kHz
speedstep-centrino: trying to enable Enhanced SpeedStep (111088)
speedstep-centrino: couldn't enable Enhanced SpeedStep
cpufreq-core: initialization failed
cpufreq-core: no CPU initialized for driver centrino
cpufreq-core: unregistering CPU 0
So can you help/tell me where i have to look for this error.
Before the firmware upgrade I made hexdump -C of the first MB of /dev/mem, maybe that could help.
Btw, PFX should not be used in dprintk(), cause speedstep-centrino: is printed twice.
I'll write a patch for that.
Greets, Henne.
