, Good , I have tested your commands from EFI 7 times. I always successed.
This is my steps:
Shell>
Shell>
Shell> mm 400 -w 2 -io -n
IO 0x0000000000000400 : 0x0011
Shell> mm 404 1c01 -w 2 -io -n
Shell> mm 404 3c01 -w 2 -io -n

PS
For System Processor Status see the SS command.
System Power state : Off #this will indicate that power has been off.
System Power usage : 22 Watts used in Auxiliary Mode
Ambient temperature : 25 C

But I can’t use debug menu MFW to check bit 0 of the FPGA register . I am not
familiar with hardware testing and debugging, could you give me some more
details information ?thanks very much!
2, I also checked my driver (located in Linux kernel from Linux acpi group).
why your actions can result in power off, but for my code , sometimes
successed, and sometimes failure ?
As you said , in this time, I must read bit 0 of FPGA to verify if FPGA worked
well .
Attachment is kernel’s acpi code related shutdown named
“acpi_enter_sleep_state() which control SLP_TYPx and SLP_EN” , if you are
interested in it ,we can compare the actions my driver did with your actions
from EFI command.
I think our core actions are basic same,
As ACPI spec, core actions should be :
- Write sleep type into SLP_TYPx bit of PM1Acontrol register and
PM1Bcontrol register
- Write 1 to SLP_EN bit of PM1Acontrol register and PM1Bcontrol register
From your EFI command, it seems that, you didn’t differ PM1Acontrol and
PM1Bcontrol , you only write a register address 0x400(it should be PM1Acontrol
register).
Following is my writing register information:
all flow is :
1, disable Clear wake status
2, Clear all fixed and general purpose status bits #same with
yours . after clear,then I read it again , 0x0000
3, will Disable/clear all GPES
4, will Enable all wakeup GPES -
5, assert SLP_TYPx and write into PM1A_CNT and PM1B_CNT #same with yours
,also 0x1c01
5, assert SLP_EN bit, and write into PM1A_CNT and PM1B_CNT #same with
yours,also 0x3c01
6, After that, delay 10s to write 1 to PM1_CNT register ‘s SLP_EN bit (equal of
step 5. Once again)
Welcome your comments for this comments from open source, for sentosa , do we
need it ?? I don’t think ,we need it.
if (sleep_state > ACPI_STATE_S3) { //this code is not written by me , but
from Linux-acpi open source group.
/*
* We wanted to sleep > S3, but it didn't happen (by virtue of the
* fact that we are still executing!)
*
* Wait ten seconds, then try again. This is to get S4/S5 to work on
* all machines.
*
* We wait so long to allow chipsets that poll this reg very slowly to
* still read the right value. Ideally, this block would go
* away entirely.
*/
acpi_os_stall(10000000); //delay 10 seconds.
// only set SLP_EN of PM1Control register.
status = acpi_hw_register_write(ACPI_REGISTER_PM1_CONTROL,
sleep_enable_reg_info->
access_bit_mask);
7, After that ,will be in a dead loop to check if ACPI_BITREG_WAKE_STATUS has
been changed 1 by hardware. If set ok, break from the loop.
My question is that ：
4.7.3.2.1 PM1 Control Registers
Register Location: <PM1a_CNT_BLK / PM1b_CNT_BLK> System I/O or Memory Space
Default Value: 00h
Attribute: Read/Write
Size: PM1_CNT_LEN
The PM1 control registers contain the fixed hardware feature control bits.
These bits can be split between
two registers: PM1a_CNT or PM1b_CNT. Each register grouping can be at a
different 32-bit aligned
address and is pointed to by the PM1a_CNT_BLK or PM1b_CNT_BLK. The values for
these pointers to
the register space are found in the FADT. Accesses to PM1 control registers are
accessed through byte and
word accesses
For acpi , why differ PM1Acontrol and PM1B control ?
PM1AControl is enough ? I need to wirte the same value into PM1Bcontrol ?
Following is my registers controlling follow. Could you give me some comments ?
thanks very much!
I explain the output format ,just like :
hwregs-0785 [E000000183320000] [05] hw_low_level_read : Read: 00000011
width 16 from 0000000000000400 (SystemIO)
it represents that ,from 0x400 address (system IO) ,read a value 0x11 , width
16,
just like your “mm 400 -w 2 -io -n”
Power down.
