Hi all ,
Now I am using hp's rx2860 which has 8 set of CPU ,which CPU has 2 cores ,totally 16 cores.
. but I found that sometimes the power can't be off after "shutdown -h 0".it seems that os has been shutdown , but power is still on.

every 5 times , I will reproduce 2 times.

maybe the code related with acpi and ia64 has some bugs or non-compatible error.

I am not very sure about this function named "acpi_enter_sleep_state() " :

====code====

       if (sleep_state > ACPI_STATE_S3) {          //why here ???????????????????????????   
               /*                                                    //can you explain more details ??????????????????????              who wrote these comments ?????
                * 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);                       //why here ? how can you get 10s , from SPEC 4.0a ? 
               status = acpi_hw_register_write(ACPI_REGISTER_PM1_CONTROL,                  //why ??? Is it necessary ??????????????
                                               sleep_enable_reg_info->
                                               access_bit_mask);
               if (ACPI_FAILURE(status)) {
                       return_ACPI_STATUS(status);
               }
       }

       /* Wait until we enter sleep state */               // why here ?????????????????????????????
       do {
               status = acpi_get_register_unlocked(ACPI_BITREG_WAKE_STATUS,
                                                   &in_value);
               if (ACPI_FAILURE(status)) {
                       return_ACPI_STATUS(status);  
               }

               /* Spin until we wake */

       } while (!in_value);  ///why here ??????????????   I query "WAK_STS" . 

       return_ACPI_STATUS(AE_OK);

My questions are :
1, from spec 4.0a , for entering S5 from S0 , we only need to set register SLP_TYPx and SLP_EN. but in this function why control so many registers ? How did the author get those informations ?

2, after "acpi_enter_sleep_state" . what will happen ?
Can you give those details . for example the sequence entering S5 state , how to make the power supply off ?
after setting acpi register ,the power will be off ? or dependent on BIOS operation or other BMC firmware ? I am not very sure these details.

thanks much for comments, any idea is welcome!

3, from http://lxr.linux.no/linux+v2.6.27.19/drivers/acpi/hardware/hwsleep.c
/* Write #2: SLP_TYP + SLP_EN */
351
352 ACPI_FLUSH_CPU_CACHE(); //Notice here!
353
354 status = acpi_hw_register_write(ACPI_REGISTER_PM1A_CONTROL,
355 PM1Acontrol);
356 if (ACPI_FAILURE(status)) {
357 return_ACPI_STATUS(status);
358 }

in ia64 architecture, ACPI_FLUSH_CPU_CACHE() is empty operation , do we need to implement it as ia64 spec ?

4, when I am debugging "acpi_enter_sleep_state()" , I found that this is a tough task because after somewhat, I can't use printk() again . so I can't trace them defintely , do you have some better solution ????

/* Insert SLP_ENABLE bit */
346

 347        PM1Acontrol |= sleep_enable_reg_info->access_bit_mask;
 348        PM1Bcontrol |= sleep_enable_reg_info->access_bit_mask;
 349
 350        /* Write #2: SLP_TYP + SLP_EN */
 351        //printk() can work !!!!!!!!!!!!!!!!!!!1
 352        ACPI_FLUSH_CPU_CACHE();

353
354 status = acpi_hw_register_write(ACPI_REGISTER_PM1A_CONTROL,
355 PM1Acontrol);

			//from here , printk() can't work any longer. I think maybe due to set bit SLP_EN.

356 if (ACPI_FAILURE(status)) {
357 return_ACPI_STATUS(status);
358 }
359
360 status = acpi_hw_register_write(ACPI_REGISTER_PM1B_CONTROL,
361 PM1Bcontrol);
362 if (ACPI_FAILURE(status)) {
363 return_ACPI_STATUS(status);
364 }

4, when I am debugging "acpi_enter_sleep_state()" , I found that this is > a tough task because after somewhat, I can't use printk() again . so I can't trace them defintely , do you have some better solution ????

Perhaps you could use the early_console code (you'd have to add some code to switch back to it). Take a look at Documentation/ia64/serial.txt. That code just pushes bytes out the serial port with very few dependencies, so it ought to keep working till very late during shutdown sequence.

thanks much for comments, any idea is welcome!

Does this problem also appear in SLES11-SP1 ... which moved to kernel version 2.6.32, and thus includes some changes to

drivers/acpi/acpica/hwsleep.c

Nothing obviously looks like it would cause this problem, but it would be nice to know if the problem has already been fixed.

Re: Re: [bug report ] hp's rx2860 (kernel is 2.6.27.19-5 in sles11 ia64)power off failrue when "shutdown -h 0" .

yes, I basicly compare hwsleep.c seperately located in sles11 and sles11sp1 . they don't have obvious difference, however , some basic functions type changed indeed.
Key code is the same. Anyway , I am testing sles11sp1's 2.6.32 kernel.

Hi,

I have a queston not confirm, thanks for answering.
from acpi sepc 2.0a

7.3.3 \_GTS (Going To Sleep)
_GTS is an optional control method. If it exists, OSPM must execute the _GTS control method just prior to setting the sleep enable (SLP_EN) bit in the PM1 control register when entering the S1, S2, S3, and S4 sleeping states and when entering S5 for orderly shutdown. _GTS allows ACPI system firmware to perform any required system specific functions prior to entering a system sleep state. OSPM will set the sleep enable (SLP_EN) bit in the PM1 control register immediately following the execution of the _GTS control method without performing any other physical I/O or allowing any interrupt servicing. The sleeping state value (1, 2, 3, 4, or 5) is passed as an argument to the _GTS control method. The _GTS method must not attempt to directly place the system into a sleeping state. OSPM performs this function by setting the sleep enable bit upon return from _GTS. In the case of entry into the S5 soft off state however, _GTS may indeed perform operations that place the system into the S5 state as OSPM will not regain control. The _GTS method must be self-contained (not call other methods). Additionally, _GTS may only access OpRegions that are currently available (see the _REG method for details).
--------
my questions are followings :

1,
especially , this sentense ,

"OSPM will set the sleep enable (SLP_EN) bit in the PM1 control register immediately following the execution of the _GTS control
method without performing any other physical I/O or allowing any interrupt servicing."

in fact ,before power supply is off , linux kernel will shutdown all devices by calling driver->shutdown() function.
if shutdown () failure, device will not be power off state. in this case, after setting the sleep enable (SLP_EN) bit ,what will happen ?
Should the power supply be off ?

Hi all,

I found a amazing problem when debugging this issue.
As ACPI spec4.0a , if we want to make the system into S5 (soft-off ) status, what we should do is like this:

P85:
The logic is controlled via two bit fields: Sleep Enable (SLP_EN) and Sleep Type (SLP_TYPx). The type of sleep state desired is programmed into the SLP_TYPx field and upon assertion of the SLP_EN the hardware will sequence the system into the defined sleeping state. OSPM gets values for the SLP_TYPx field from the \_Sx objects defined in the static definition block. If the object is missing OSPM assumes the hardware does not support that sleeping state. Prior to entering the desired sleeping state, OSPM will read the designated \_Sx object and place this value in the SLP_TYP field.

One word , we should write a value to register SLP_TYP, afterwards , set SLP_EN bit, hardware will sequence the system into the defined sleeping state (for example S5). From this sentence " Each sleeping object contains two constant 3-bit values that OSPM will program into the SLP_TYPa and SLP_TYPb fields (in fixed register space)." We can simply get a conclusion : The value written to SLP_TYP should be different between S0~S5 ,moreover , this value is gotten from firmware , not controlled by us. But in debugging information, I can see that for S0~S5 , they have the same value by converting ,and then written to SLP_TYP. (see "acpi_enter_sleep_state() ").

My debugging code:

acpi_status acpi_enter_sleep_state_prep(u8 sleep_state) {
	acpi_status status;
	struct acpi_object_list arg_list;
	union acpi_object arg;

	ACPI_FUNCTION_TRACE(acpi_enter_sleep_state_prep);

	//added by Bob for checking all type_a and type_b values for different State(S0~S5), should be different.
	{
		int i=0;
		u8 bobtype_a;
		u8 bobtype_b;

		for(i=0;i<6;i++) {
			acpi_get_sleep_type_data(sleep_state, &bobtype_a, &bobtype_b);
			printk("for S[%d] status , type_a=%d, type_b=%d\n",sleep_state,bobtype_a,bobtype_b);
		}
	} //over.
	

	//this code is from kernel. Kernel (OSPM) will get this value from firmware ,and by somewhat converting, and then write it into SLP_TYP .
	/*
	 * _PSW methods could be run here to enable wake-on keyboard, LAN, etc.
	 */
	status = acpi_get_sleep_type_data(sleep_state,
					  &acpi_gbl_sleep_type_a,
					  &acpi_gbl_sleep_type_b);
	if (ACPI_FAILURE(status)) {
		return_ACPI_STATUS(status);
	}

Following is partial output information:
We can see that, for S0~S4 ,they all have {128,7) , it apparently is wrong as ACPI 4.0a SPEC. For S5 , it is {7,7}.

I finally found "S5" definition , details can got from my following reply. Next step, I will send this information to firmware engineer to verify SSDT17.dsl is right for our sentosa. Because same values into registers every
time, but got different hardware behaviors.
So we must doubt hardware and firmware design.
Now, from software point of view : acpi_enter_sleep_state() is the last function to run when shutdown machine , which write value into acpi registers
to tell hardware to enter S5 (SLP_TYPx and SLP_EN) .Once written to these two
registers, software task has been over. The left things are hardware is to work. So I think Linux kernel is good, this issue is from related with kernel,at acpi driver's logic is right. I have printed values which will be written to acpi registers , those values are the same every time, but hardware
has different behaviors , so we need firmware engineer to help me check .

Maybe I need to ask firmware designer what is the meaning of this definition:
Where is {0x7,0x7} from ?? which datasheet ? which document ? In "SSDT17.dsl" .
DefinitionBlock ("SSDT17.aml", "SSDT", 2, "HP ", "RX2800-2", 0x00000007)

{
     Scope (\)
     {
         Name (\_S5, Package (0x03)
         {
             0x07,
             0x07,
             Zero
         })
     }

This is equal of that return from acpi_get_sleep_type_data(5,&type_a, &type_b)
