Tablet PC + 2.4.18 + acpi 20020726 + swsup11 working !

[Robert Wörle]

Hi Folks

Im a smurf reader of this list and i ve been trying ACPI now for more 
than 5 months .
The device i want to have ACPI running is the worlds first Tablet PC 
called  "Pacebook" .
As i am pretty much the only linux enthusiastic at our company , im 
"porting " linux to that Tablet .

Until now ACPI was quite good working : I can read the battery state , 
see if im plugged or not , get the temperatur of the TRANSMETA (!) and 
all that minor stuff , BUT i had no chance to use S3 S4 ---until 
yesterday when i tried the mentioned patches and now can S4 very good !!
--YES it is working ! __ icantbelievethat _

So guys : I congratulate you ! Very very very good work !

Things TODO now :
try to get S3 also working ( to have this , ive to implement a function 
to turn off the backlight )
i ve the spec`s and I/O Port to do that  ,but im still expierencing 
problems at starting to write this driver , since
a device called pic2 is loaded at the needed I/O Port  ( 0xB1-0xB2) ...

When i ve finished that driver ive to find a way , where the ACPI 
Subsystem can call that backlight_off function.

What is the supposed procedure to implement such "thirdparty" functions 
into ACPI ?
will there be a script to be called ( like at APM , where we had 
apmd_proxy to shutdown critical things before suspend ) ?


Anyhow folks ... im very proud of that community and keep up doing that 
great work !

Regards Rob

If I remember well, those ports are actually used by the AML with some
mutex.  If you use ACPI and the "still need to be written" driver for your
tablet at the same time, you must to take into account this fact.

It should be called by a Method if the AML is well written.  So, in a
perfect world, you should not take care about that if S3 work.  Of course,
the world is not so perfect, but who knows :)

Try to see if something like John Belmonte have already written for a skeleton.

So what is this pci1 and pic2 thing ??? and why is it residing at my 
wanted IO ???
Do i maybe just have to modify the HEX commands at some ACPI.c according 
device ??

Let me guess: PIC = Programmable Interrupt Controller,
so I think you don't wanna mess with it! The interesting question is, why is 
your device in this range? This ports are reserved since the days of IBM's 
good old AT.

Well, not all those ports are used by the original 8259A.  And the PIC 2, is
'only' at range A0-AF, according to Ralf Brown list.  Linux extend it a little,
but I don't know why.

I guess it depends on which chipset is used or checked then.
I just checked the 82801BA-ICH2 (Intel).
It says that PIC2 is in about 1/2 of the IO addresses between
0xa0 and 0xbd inclusive, with 0xb2-0xb3 used for Power Management.

ACPI on Compaq Presario 1720US

[Prabhakar Reddy Gudla Venkata Siva]

Hi list,

Have seen few folks getting fair amt of sucess with the ACPI on Compaq
Presario models. I am keen to try out the ACPI (have tried few months
back), especially modifiying my DSDT.

I have tried several times to get the AD Utility from the Phoenix website
but looks like they have removed that utility. Can anyone point me where I
can get a ACPI Deassembeler or an alternate method to get "asl" output of
my DSDT.

TIA

Tell me guys , what driver is this pic2 .. where can i found the 
according **.c to have some try`S and modify it
so if it doesnt need these ports then i can use them for my purposes ...

The code (initialization at least) is in arch/i386/kernel/i8259.c

The IO space for PIC1 and PIC2 is reserved in
linux/arch/i386/kernel/setup.c, around line 330 in 2.4.18/2.4.19,
in the array standard_io_resources[].
You might be able to make the granularity of that definition
finer so that some of the IO addresses aren't reserved.

Regarding someone else's email about Linux using only addresses
0xa0 and 0xa1 for PIC2:
That's probably correct.  The PIC internal registers are addressed
by ICWn and OCWn, which are dependent on the data values written.
The other IO addresses that are reserved (like 0xa4-5, 0xa8-9,
0xac-d, 0xb0-1, 0xb4-5, 0xb8-9, 0xbc-d) are ghosts (duplicates)
of the base IO addresses (0xa0-0xa1), due to incomplete IO address
line decoding.

Thank you , i found it at setup.c ... and i ll now try to free my needed 
area with something like this:
{"pic2",0xa0,0xb0,IORESOURCE_BUSY},
("pic2",0xb3,0xbf,IORESOURCE_BUSY},----
after that i should (=?!) have 0xb1-0xb2 free to be mapped by my driver ...

I don't know why you want to free those ports.  I use those ports in
my module with no trouble at all, and apm use them too without any need
to free them.  What I wanted to warn you in my first post was that their
are a lot of use of those ports in the dsdt.  Those ports are already acceded
by ACPI Methods and those methods use a mutex in order to access those
ports.  Also if you don't care about this fact and use ACPI at the same
time, you can experiment some race conditions with your driver.
