-====== amdtemp ====== 
-Completely rewritten amdtemp driver.\\ 
-There is no longer binding to the processor ID, all the new processors will be supported without the need to modify the code.\\ 
- 
-**Download**: [[http://netlab.linkpc.net/download/software/FreeBSD/patches/amdtemp.c|amdtemp.c]] [[https://reviews.freebsd.org/D9759|D9759]]\\ 
-**Licence**: BSD\\ 
- 
- 
-===== Read methods ===== 
-  - D18F3xE4 Thermtrip Status Register (TTS) - all registers are read-only.  
-  - D18F3x64 Hardware Thermal Control (HTC) - everything except HtcTmpLmt available for recording. 
-  - D18F3xA4 Reported Temperature Control Register (RTC) - everything except CurTmp available for recording. 
-  - SB-TSI - Temperature Sensor Interface via CPU registers (TSI) - most writable.  
-  - TSI via SMBus - **not implemented!** 
-**sensor_offset** - can be customized for each sensor separately. 
- 
- 
-===== Tunables ===== 
-Register values ​​can be found in the documentation on the processor.\\ 
- 
-==== D18F3xE4 Thermtrip Status Register ==== 
-  * **TjOffset** (RD) - This field is the offset from CurTmp used to normalize to Tcontrol. 
-  * **DiodeOffset** (RD) - Thermal diode offset is used to correct the measurement made by an external temperature sensor. 
-  * **ThermtpEn** (RD) - The THERMTRIP state is supported by the processor. 
-  * **Thermtrip** (RD) - The processor has entered the THERMTRIP state. 
- 
- 
-==== D18F3x64 Hardware Thermal Control (HTC) ==== 
-  * **HtcTmpLmt** (RD, Kelvin) - HTC temperature limit 
-  * **HtcHystLmt** (RW, Kelvin) - HTC hysteresis. The processor exits the HTC active state when the temperature selected by HtcSlewSel is less than the HTC temperature limit (HtcTmpLmt) minus the HTC hysteresis (HtcHystLmt). 
-  * **HtcEn** (RW) - HTC is enabled; the processor is capable of entering the HTC-active state. 
-  * **HtcLock** (RW) - HtcPstateLimit, HtcHystLmt, HtcTmpLmt, and HtcEn are read-only. 
-  * **HtcSlewSel** (RW) - HTC slew-controlled temperature select. 
-  * **HtcPstateLimit** (RW) - HTC P-state limit select. 
-  * **HtcAct** (RW) - The processor is currently in the HTC-active state. 
-  * **HtcActSts** (RW) - set-by-hardware; write-1-to-clear. Reset: 0. This bit is set by hardware when the processor enters the HTC-active state. It is cleared by writing a 1 to it. 
-  * **PslApicHiEn** (RW) - P-state limit higher value change APIC interrupt enable. 
-  * **PslApicLoEn** (RW) - P-state limit lower value change APIC interrupt enable. 
- 
- 
-==== D18F3xA4 Reported Temperature Control Register ==== 
-  * **CurTmp** (RD, Kelvin) - Provides the current control temperature, Tctl, after the slew-rate controls have been applied. 
-  * **CurTmpTjSel** (RW, Kelvin) - Specifies a value used to create Tctl. 
-  * **TmpSlewDnEn** (RW) - Temperature slew downward enable. 
-  * **TmpMaxDiffUp** (RW) - Specifies the maximum difference, (Tctlm - Tctl), when Tctl immediatly updates to Tctlm. 
-  * **PerStepTimeDn** (RW) - Specifies the time that Tctlm must remain below Tctl before applying a 0.125 downward step. 
-  * **PerStepTimeUp** (RW) - Specifies the time that Tctlm must remain above Tctl before applying a 0.125 upward step. 
- 
- 
-==== SB-TSI registers ==== 
-  * **cpu_temperature** (RD, Kelvin) - CPU Temperature 
-  * **high_temperature_threshold** (RD, Kelvin) - High Temperature Threshold 
-  * **low_temperature_threshold** (RD, Kelvin) - Low Temperature Threshold 
-  * **cpu_temperature_offset_hi** (RW) - CPU Temperature Offset High Byte 
-  * **cpu_temperature_offset_lo** (RW) - CPU Temperature Offset Low Byte 
-  * **status** (RW) - SB-TSI Status 
-  * **cfg3** (RW) - SB-TSI Configuration Register 0x03 
-  * **cfg9** (RW) - SB-TSI Configuration Register 0x09 
-  * **upd_rate** (RW) - Update Rate 
-  * **timeout_cfg** (RW) - Timeout Configuration 
-  * **alert_threshold** (RW) - Alert Threshold 
-  * **alert_cfg** (RW) - Alert Configuration 
-  * **manufacture_id** (RD) - Manufacture ID 
-  * **revision** (RD) - SB-TSI Revision 
-

-===== Installing ===== 
-  - download 
-  - replace amdtemp.c at /usr/src/sys/dev/amdtemp/ 
-  - Rebuild and install module: <code>kldunload amdtemp 
-cd /usr/src/sys/modules/amdtemp/ 
-make 
-make install 
-make cleandir 
-</code> 
- 
- 
-===== Usage ===== 
-Load module: 
-<code>kldload amdtemp</code> 
- 
-Auto load on system start: **/boot/loader.conf** 
-<code>amdtemp_load="YES"</code> 
-Or add **kld_list** to: **/etc/rc.conf**, example: 
-<code>kld_list="amdtemp"</code> 
- 
-Show temperature:
