Subject: ACPI P-States vs Longhaul
Date: Mon, 20 Nov 2006 20:37:25 +0100 [thread overview]
Message-ID: <456203F5.60606@interia.pl> (raw)
Hello,
I know that a lot has changed since 2.6.18 in "ACPI P-States"
driver, but I wasn't paing attention. Just in case if this
issue isn't known. Reported by user.
System: VIA Epia SP13000 (VIA C3-2 "Nehemiah" 6.9.8)
Kernel: 2.6.18.2 custom config, apci-cpufreq=m, longhaul=m
Issue:
"ACPI P-States driver" is loaded (by distro) and stays loaded.
When user try to load "Longhaul" CPU is already owned by other
driver and "Longhaul" fails with -EBUSY. Of course rmmod does
the trick. But why acpi-cpufreq didn't failed? This processor
don't support P-states.
Sadly "Longhaul" don't work too. No ACPI C3 support in BIOS
and CN400 chipset on mainboard.
Regards
Rafa³
