how to create a DSDT patch with these requirements?

[mrjayviper]

1. In Device (PWRB), change Name (_HID, EisaId ("PNP0C0C")) to Name (_CID, EisaId ("PNP0C0C")).

 

2. change string "Store (Local0, Local0)" to "Store (0x00, Local0)"

 

I've looked at examples from olarila but still confused on what to do.

 

thank you very much

hello

 

i don't really get what u want but ..

 

why u don't do the chances with a dsdt editor manually ?

 

u should read + about what are u trying to do ..

 

good hack

1. I'm trying to create a patch file I can use every time instead of doing the edit manually.

 

I gave 2 examples of what I want to do. they are very easy to do when editing manually but as I said, I want to create a patch file.

 

2. I do not know what to read on how to create a DSDT patch file. can you please point me to a good guide?

 

thanks again!

hello

 

the first are already done

 

http://olarila.com/Patches/Desktop/HID%20para%20CID.txt

 

the second post the method or device to see

 

good hack

[mrjayviper]

thanks very much for the help!

 

as for the second help

        Method (_MSG, 1, NotSerialized)
        {
            Store (Local0, Local0)
        }
 
        Method (_SST, 1, NotSerialized)
        {
            Store (Local0, Local0)
        }

how do I change those 2?

[artur_pt]

hello

 

and that will not give u any errors ? when compile it

 

post all device and method

 

should post also ur dsdt ..

 

good hack

thank you so much for the link. it's very helpful

 

-------------------------

 

another question though.

 

how do I find the value I need to use when using "parent_adr". I looked at the wiki and there are hardly any examples in there.

 

example: 

How do I find "0x001B0000"?

 

 

into method label _DSM parent_adr 0x001B0000 remove_entry;
into device name_adr 0x001B0000 insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    Store (Package (0x08)\n
        {\n
            "codec-id", \n
            Buffer (0x04)\n
            {\n
                0x88, 0x08, 0xEC, 0x10\n
            }, \n
            "layout-id", \n
            Buffer (0x04)\n
            {\n
                0x78, 0x03, 0x00, 0x00\n
            }, \n
            "device-type", \n
            Buffer (0x0F)\n
            {\n
                "Realtek ALC888"\n
            }, \n
            "PinConfigurations", \n
            Buffer (One)\n
            {\n
                0x00\n
            }\n
        }, Local0)\n
    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))\n
    Return (Local0)\n
}
end;

parrent_adr is PCI port/slot address.

 

example.

in terminal i run lspci (install it first)

$ lspci

...

00:1a.0 USB Controller: Intel Corporation Ibex Peak USB2 Enhanced Host Controller (rev 06) = 0x001a0000

00:1b.0 Audio device: Intel Corporation Ibex Peak High Definition Audio (rev 06) = 0x001b0000

...

 

or get it with ioreg. explorer

 

HDEF@1B = 0x001b0000

 

 

in DSDT:

 

Device (USBE)

            {

                Name (_ADR, 0x001A0000)

...

Device (USB4)

            {

                Name (_ADR, 0x001A0001)

 

ok now

 

into method label _DSM parent_adr 0x001B0000 remove_entry;
into device name_adr 0x001B0000 insert
begin

if you look at patch you pasted. You search for parent_id 0x001B0000 but sometimes you can't find it because it's not there.

so patch would be something like this: 

 

adding new device (HDEF) sound.

 

into device label PCI0 insert begin
Device (HDEF)\n
        {Name (_ADR, 0x001B0000)\n
        	Name (_STA, 0x0F)\n
        	Name (_PRW, Package (0x02)\n
        	{0x09, 0x04})\n
		
            Method (_DSM, 4, NotSerialized)\n
            {If (LEqual (Arg2, Zero))\n
                {Return (Buffer (One)\n
				{0x03})\n
                }\n
				Return (Package (0x12)\n
                {\n		
				"MaximumBootBeepVolume", Buffer (One) {0x4D},\n
				"hda-gfx",		Buffer (0x0A) {"onboard-1"},\n
				"AAPL,slot-name",	Buffer (0x09) {"Built In"},
				"built-in", 		Buffer (One) {0x00},\n
				"device_type",		Buffer (0x06) {"AUDIO"},
				"name", 		Buffer (0x0F) {"Realtek ALC889"},\n
				"model",		Buffer (0x27) {"Realtek ALC889HD High Definition Audio"}, 
				"layout-id",		Buffer (0x04) {0x0C, 0x00, 0x00, 0x00},\n 
				"PinConfigurations", 	Buffer (Zero) {}\n
                })\n
            }\n
        }\n
end;
