Hi, Norman
Thanks for the info.
What Alexey said is right. The remained two problems are caused by broken
BIOS.
a. /proc/acpi/processors/CPU0/info
In the DSDT there is no PBLK address in the definition of processor block.
>Processor (\_PR.CPU0, 0x00, 0x00000000, 0x00)
Correct defintion should be : Processor(\_PR.CPU0, 0x00, 0x410, 0x06)
At the same time there is no _PTC defintion for throttling control in DSDT.
The flag of throttling control and limit will be zero.
In the FADT table the following can be found:
[060h 096 2] C2 Latency : 0065 .
[062h 098 2] C3 Latency : 03E9
[068h 104 1] Duty Cycle Offset : 01
[069h 105 1] Duty Cycle Width : 01
In the DSDT table there is no _CST defintion for power management. And C2
latency 0x65 > 100, C3 latency 0x3E9 > 1000 means that system can't support C2
/C3. The power interface can't be supported.
b. Temperature always is 40.
In the DSDT table the result of _TMP is related to the following two
definitions:
SENF, SSHU
If the values of SENF and SSHU are both one, the temperature will always be
40. (Linux can't fix it).
The output in comment #22 can confirm whether the the values are one.
