Wasn't sure if this would be better directed to -hardware.
I'm attempting to read the temperatures of my CPUs on my dual Xeon Tyan 2720 running 5.4-STABLE.
According to the manual, the motherboard has supports diagnostics via smbus, so I dutifully built a new kernel with the smbus and i2c options. The docs says Winbond 83782D is accessible on slave 0x29 for CPU fans, voltage and system temperature. The W83627HF at slave 0x2A has 3 addtional chassis fan sensors.
So far, no problem. I've been able to read these via healthd, xmbmon or lmmon. I've fiddled with them a bit to make sure they're looking at the right slave address, but other than that reading the smbus makes sense.
Here's where I'm stuck. The manual says the Xeons have on-chip thermal sensors at slave 0x18 & 0x19, both at bank 0 and register 0. When I try to read these, I get a "Device not configured" error from the ioctl call.
I've come across a few refs to the hw.acpi.thermal.tz1.temperature sysctl, but that OID's apparently not available to me.
Any suggestions? _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
