Hi, I have several servers with Opteron processors running RHEL v4. I've successfully gotten CPU frequency scaling working (which I tested by looking at the cpu frequency before and during running a CPU intensive task). However, there are currently 2 issues: 1) cat /proc/acpi/thermal_zone/* is empty (there's nothing under the thermal_zone directory) 2) I get the impression that the voltage doesn't change even though the CPU frequency changes. Is there any way to check for this? Thanks. Thanks for your help. -- Mathew Brown mathewbrown@xxxxxxxxxxx -- http://www.fastmail.fm - One of many happy users: http://www.fastmail.fm/docs/quotes.html - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
