Hi Justin, Sorry for the late reply. The temp value is returned in the EAX register (0xC000002) but in your case it's all zero. I don't know why that is. I also noticed, that your CPU has a 0xC000003 perf register whereas my datasheet only defines perf registers up to 0xC0000002. I'll try to get a newer datasheet from VIA, maybe something changed. There's nothing more I can do at the moment, sorry. ...juerg On Wed, Sep 10, 2008 at 10:29 AM, Justin Chudgar <justin at justinzane.com> wrote: > Summary: sensors with the c7temp module loaded on an HP MiniNote 2133 with a > VIA C7 running Kubuntu Hardy 2.6.24-19-generic show the CPU voltage but > always shows "0" for the temperature. > > Here is the output from uname, sensors, cpuid, cpuid -r, lspci: > > Linux justin-mininote 2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21 UTC 2008 > i686 GNU/Linux > > ------------- > > c7temp-isa-0000 > > Adapter: ISA adapter > > in0: +0.80 V > > temp1: +0.0?C > > ------------- > > CPU: > > vendor_id = "CentaurHauls" > > version information (1/eax): > > processor type = primary processor (0) > > family = Intel Pentium Pro/II/III/Celeron, AMD Athlon/Duron, Cyrix M2, VIA > C3 (6) > > model = 0xd (13) > > stepping id = 0x0 (0) > > extended family = 0x0 (0) > > extended model = 0x0 (0) > > (simple synth) = VIA C3 / C3-M / C7 / C7-M / Eden ESP 7000/8000/10000 > (unknown model) > > miscellaneous (1/ebx): > > process local APIC physical ID = 0x0 (0) > > cpu count = 0x0 (0) > > CLFLUSH line size = 0x8 (8) > > brand index = 0x0 (0) > > brand id = 0x00 (0): unknown > > feature information (1/edx): > > x87 FPU on chip = true > > virtual-8086 mode enhancement = true > > debugging extensions = true > > page size extensions = true > > time stamp counter = true > > RDMSR and WRMSR support = true > > physical address extensions = true > > machine check exception = true > > CMPXCHG8B inst. = true > > APIC on chip = true > > SYSENTER and SYSEXIT = true > > memory type range registers = true > > PTE global bit = true > > machine check architecture = false > > conditional move/compare instruction = true > > page attribute table = true > > page size extension = false > > processor serial number = false > > CLFLUSH instruction = true > > debug store = false > > thermal monitor and clock ctrl = true > > MMX Technology = true > > FXSAVE/FXRSTOR = true > > SSE extensions = true > > SSE2 extensions = true > > self snoop = false > > hyper-threading / multi-core supported = false > > therm. monitor = true > > IA64 = false > > pending break event = true > > feature information (1/ecx): > > PNI/SSE3: Prescott New Instructions = true > > MONITOR/MWAIT = false > > CPL-qualified debug store = false > > VMX: virtual machine extensions = false > > Enhanced Intel SpeedStep Technology = true > > thermal monitor 2 = true > > context ID: adaptive or shared L1 data = false > > cmpxchg16b available = false > > xTPR disable = true > > extended processor signature (0x80000001/eax): > > generation = 0x0 (0) > > model = 0x0 (0) > > stepping = 0x0 (0) > > (simple synth) = unknown > > extended feature flags (0x80000001/edx): > > x87 FPU on chip = false > > virtual-8086 mode enhancement = false > > debugging extensions = false > > page size extensions = false > > time stamp counter = false > > RDMSR and WRMSR support = false > > physical address extensions = false > > machine check exception = false > > CMPXCHG8B inst. = false > > APIC on chip = false > > SYSCALL and SYSRET instructions = false > > memory type range registers = false > > global paging extension = false > > machine check architecture = false > > conditional move/compare instruction = false > > page attribute table = false > > page size extension = false > > multiprocessing capable = false > > AMD multimedia instruction extensions = false > > MMX Technology = false > > extended MMX = false > > SSE extensions = false > > AA-64 = false > > 3DNow!
