* MFC r225662:Attilio Rao2011-10-031-1/+4
| | | | | | | | | Cleanup #PROCHOT sticky assertion. Sponsored by: Sandvine Incorporated Notes: svn path=/stable/8/; revision=225933
* MFC r225339:Xin LI2011-10-021-60/+157
| | | | | | | | | | | | | | Expose more variables from coretemp(4) via sysctl: - tjmax - Tj(max) value from the CPU - delta - current delta reading - resolution - sensor resolution in Celsius - throttle_log - whether a #PROCHOT was asserted since last reset Submitted by: Mark Johnston <markjdb gmail.com> (mostly) Notes: svn path=/stable/8/; revision=225916

* MFC r221335:Xin LI2011-05-051-1/+1
| | | | | | | | | | Correct a typo. According to Intel document 318914, the Tj(max) for Core 2 Duo Mobile CPUs should be 105. Noticed by: Mark Johnston <markjdb gmail.com> Notes: svn path=/stable/8/; revision=221493

| | | | | | | | | | | | | | | | | | | | | | | | Improve cputemp(4) driver wrt newer Intel processors, especially Xeon 5500/5600 series: - Utilize IA32_TEMPERATURE_TARGET, a.k.a. Tj(target) in place of Tj(max) when a sane value is available, as documented in Intel whitepaper "CPU Monitoring With DTS/PECI"; (By sane value we mean 70C - 100C for now); - Print the probe results when booting verbose; - Replace cpu_mask with cpu_stepping; - Use CPUID_* macros instead of rolling our own. Catch known CPUs before using IA32_TEMPERATURE_TARGET. This way we would have an opportunity to hide the Tj(target) value doesn't seem right stuff if we know it's not working there. Add temperature value for Core2 Duo Extreme Mobile that I have access to. Notes: svn path=/stable/8/; revision=211914

and newer CPUs (including Core 2 and Core / Core 2 based Xeons). The driver attaches to each cpu device and creates a sysctl node in that device's sysctl context (dev.cpu.N.temperature). When invoked, the handler binds to the appropriate CPU to ensure a correct reading.
