PMC Controller

MVeer2 — Sun, 21 Jan 2018 14:56:17 GMT

Dear all,

I have programmed APM controller in 8-series PCH to move to soft-off sleep state. But now it has been moved to Bus 0, Device 31 and Function 2.Below is the code for moving to soft-off sleep state upto X99 PCH.

_BtLdrTurnOffPC:

push ax

push bx

push cx

push dx

push si

push di

push ds

push es

cli

mov eax,0x8000F840; Bus 0, Device 31, Function 0, Offset 0x40

mov dx,0x0CF8

out dx,eax

mov dx,0x0CFC

in ax,dx

and ax,0xFFFE

mov dx,ax

add dx,0x0004

mov eax,0x00003C00

out dx,eax

pop es

pop ds

pop di

pop si

pop dx

pop cx

pop bx

pop ax

ret

Will the following code work with no change for 100-series PCH onwards?

_BtLdrTurnOffPC:

push ax

push bx

push cx

push dx

push si

push di

push ds

push es

cli

mov eax,0x8000FA40 ; Bus 0, Device 31, Function 2, Offset 0x40

mov dx,0x0CF8

out dx,eax

mov dx,0x0CFC

in ax,dx

and ax,0xFFFE

mov dx,ax

add dx,0x0004

mov eax,0x00003C00

out dx,eax

pop es

pop ds

pop di

pop si

pop dx

pop cx

pop bx

pop ax

ret

Thanks in advance. Kindly intimate me as early as possible since this is urgent.

Dear all,

This is Muhilan Veerarasu from India. This code is my own design. I referred following for 8-series PCH ACPI.

Manual:- Intel 8-series-chipset-pch-datasheet.pdf

Chapter:- 5 - Functional description

Sections:- 1. 5.14 - Power management

2. 5.14.7.2 - Initiating sleep state.

3. 12.1.13 - ACPI BASE ADDRESS REGISTER

4. 18.8.3 - Power Management I/O Registers

And i designed following code for 8-series PCH Motherboards.

_BtLdrTurnOffPC:

push ax

push bx

push cx

push dx

push si

push di

push ds

push es

cli

mov eax,0x8000F840; Bus 0, Device 31, Function 0, Offset 0x40

mov dx,0x0CF8

out dx,eax

mov dx,0x0CFC

in ax,dx

and ax,0xFFFE

mov dx,ax

add dx,0x0004

mov eax,0x00003C00

out dx,eax

pop es

pop ds

pop di

pop si

pop dx

pop cx

pop bx

pop ax

ret

In the above code, I directly fetch APM Base address register and turn off PC. However, From Intel 100-series PCH onwards, PMC has be moved to new PCI Bus location.

I modified this code to following with some changes for intel 100-series PCH motherboard onwards.. This code has be designed with Bus# 0, Device# 31, Function# 2 and offset 0x40(ACPI Base address register).

_BtLdrTurnOffPC:

push ax

push bx

push cx

push dx

push si

push di

push ds

push es

cli

mov eax,0x8000FA40 ; Bus 0, Device 31, Function 2, Offset 0x40

mov dx,0x0CF8

out dx,eax

mov dx,0x0CFC

in ax,dx

and ax,0xFFFE

mov dx,ax

add dx,0x0004

mov eax,0x00003C00

out dx,eax

pop es

pop ds

pop di

pop si

pop dx

pop cx

pop bx

pop ax

ret

Will this code work? Will bios write ACPI Base address register and will enable it?

Thanks in advance. Kindly intimate me as early as possible since this is urgent.
