Code injection via DSDT for NVIDIA graphics

Created by Team EvOSX86
In this third guide, board and add to our DSDT code, graphics injection that will enable us to stop using Efi strings or injectors
Nvidia video card.
* Note: We've had success with this technique for some GMA950, ATI X3100 and some of the series X1xxx but not yet in HD.
Tools needed:
Ioregistry explorer
Nvidia graphics card working 100% including video outputs needed (QE and Hardware CI).
Having previously read chapter one and two of the guide
Content:
1. How to recognize where our video card in the registry and its associated devices.
2. Decompilation file and added COFIG DSDT.aml chart.
2a. The loader code.
3. Comparison of our code with Ioreg added Nvcaps, reg and renamed.
4. Basic structure of video devices and the DSDT added to our code.
4a. Example portable.
4b. Example computer tower.
5. Compiling and testing.
APPENDIX: How to clean our DSDT video inputs nonfunctional

1. How to recognize where our video card and registration devices
partners.
After downloading the program Ioregistry explorer, executive, we walk the tree of entries until we find the reference for our
video card, usually tends to be quite clear:
This example is from a laptop with a 256MB Nvidia 8600GT using the latest patches as Nvinject video and injector.
Pic1

As you will see, is not marked in green line corresponds to the card, but the upper, and has an explanation: in the DSDT code does not find his name, but with
the device that houses it.
Let me explain a bit these devices:
Marked in red is the AGP device @ 1, which depends on PCI @ 0, this device houses a device called a sub-VID @ 0, which is our video card.
In turn, the device VID @ 0 contains other devices that do not see, such as LCD, VGA, etc.

2. Decompilation of the code and added dsdt.aml chart.

Assuming that prior to this guide you have got to have a fixed DSDT and operational (HPET and RTC patched etc ...) you make a backup file and DSDT.aml
We have to work on.
In previous guides we have spoken of the binary called "iasl" found inside the folder "tools" created by the patcher Fassler. I repeat the recommendation that
copieis this file in / usr / bin with this I will always be available when you open the terminal and not have to be Recordade where we have given, or drag it to the terminal
every time we change our archive dst.dsl
That said, having copied the binary to start with where we mentioned decompilation of DSDT.aml:
Open terminal as root logueamos us and agree to the folder where we alamacenado the DSDT (cd "path to the folder")
once inside type in "-d iasl dsdt.aml"
This will create DSDT.dsl, we make a copy for backup and have it move away from the tools folder to avoid overcrowding of.
Now prodeas DSDT.dsl edit using a text editor of our choice (suggested textmate)
For this example we will use a DSDT from a laptop.
Note: The code marked in red is not used.
   The blue outlines the part that we must adapt to our video card.

Renowned for our card in the code outsider.
                                                     
If you look at the letters in blue is suggested, you will see that marked the buffer and the name of the card, why?, It is simple, you will have to change the name of the card
for yours, and the buffer indicating the number of characters (including spaces) is in the name quoted 1 if you change the name but not the buffer, the
compilation will fail.
How to find the buffer (which is also in hexadecimal).
It is very simple, we need a converter decimal to hexadecimal and vice versa.
A site that you can come very convenient is this:
http://www.parkenet.com/apl/HexDecConverter.html
or this:
http://www.paulschou.com/tools/xlate/
Well, he began:
Sample buffer for the line "Nvidia GeForce 8600M GS 256MB, the number of letters and spaces contained here is 30 (decimal), add 1 to the result (actually it
The problem is that the account number starts from zero), which gives us 31, using the websites listed above, we put 31 in decimal and as a result gives us 1F
hexadecimal, ie, the buffer used.
If we change the name to our card, we use the same approach to calculate the size of the buffer.

2a. The loader code.

We will give an overview of the concept of loader code already discussed in the previous guide.
Our code is not ACPI is a string of information that add to the ACPI code, and if we as-is, our record's not OSX not being charged this compatible
ACPI, so this is loaded, we must use a "shipper" which is nothing more than a bit of code that define our entry code and allow its load by
system.
Where to insert the "shipper"?
This is simple, you must seek with the text editor area code _WAK called, and when the definition of it, fit the loader code.
Charger Code:

CODE

Method (DTGP, 5, NotSerialized)

{

If (LEqual (Arg0, Buffer (0x10)

{

/* 0000 */ 0xC6, 0xB7, 0xB5, 0xA0, 0x18, 0x13, 0x1C, 0x44,

/* 0008 */ 0xB0, 0xC9, 0xFE, 0x69, 0x5E, 0xAF, 0x94, 0x9B

}))

{

If (LEqual (Arg1, One))

{

If (LEqual (Arg2, Zero))

{

Store (Buffer (One)

{

0x03

}, Arg4)

Return (One)

}

If (LEqual (Arg2, One))

{

Return (One)

}

}

}

Store (Buffer (One)

{

0x00

}, Arg4)

Return (Zero)

}

Cargo Area:
The code in this area will depend on the machine, and basically you have to find the end _WAK code, which ends:

CODE

Return (Package (0x02)

{

Zero,

Zero

})

}

I include below the code loader.
EXAMPLE:
More cargo area shipper:

CODE

Method (_WAK, 1, NotSerialized)

{

P8XH (One, 0xAB)

If (LOr (LEqual (Arg0, 0x03), LEqual (Arg0, 0x04)))

{

If (And (CFGD, 0x01000000))

{

If (LAnd (And (CFGD, 0xF0), LEqual (OSYS, 0x07D1)))

{

TRAP (0x3D)

}

}

}

If (LEqual (RP2D, Zero))

{

Notify (\_SB.PCI0.RP02, Zero)

}

If (LEqual (Arg0, 0x03)) {}

If (LEqual (Arg0, 0x04))

{

\_SB.PCI0.LPCB.EC0.SELE ()

}

P8XH (Zero, 0xCD)

Return (Package (0x02)

{

Zero,

Zero

})

}

Method (DTGP, 5, NotSerialized)

{

If (LEqual (Arg0, Buffer (0x10)

{

/* 0000 */ 0xC6, 0xB7, 0xB5, 0xA0, 0x18, 0x13, 0x1C, 0x44,

/* 0008 */ 0xB0, 0xC9, 0xFE, 0x69, 0x5E, 0xAF, 0x94, 0x9B

}))

{

If (LEqual (Arg1, One))

{

If (LEqual (Arg2, Zero))

{

Store (Buffer (One)

{

0x03

}, Arg4)

Return (One)

}

If (LEqual (Arg2, One))

{

Return (One)

}

}

}

Store (Buffer (One)

{

0x00

}, Arg4)

Return (Zero)

}

Salváis the file and compile to see if there were errors in the code.
Open the terminal, as root logueamos us and tune into the DSDT folder (cd "path to the folder) then type
iasl-f dsdt.dsl

If errors occur is that you put the wrong charger, if warnings occur, is that it may come before, not do them much attention now.
If no error occurs, delete the file that was generated DSDT.aml and continued work within DSDT.dsl
3. Comparison of our code with Ioreg added Nvcaps, reg and
renamed.
We now proceed to seek the necessary data on our IOREG for insertion into each unit in the code.
NVCAPS or seek first the configuration of the outputs of our video card and NVPM or energy management.
We opened the IOREG and seek our video card, pointing device and look for the entry child NVCAP and NVPM:

Pic2

Once we have NVCAP values and NVPM, amend our code.
Now look at the value of the input REG:

Pic 3

Change value of REG in the graphical code, so you get the real value is in our system.

4. Basic structure of video devices and the DSDT added
of our code.
4a. Example using a laptop.
Let's open the DSDT.dsl and look through the keyword "device" until we get to:

CODE

Device (AGP)

We will find the device tree in this way (different colors for each device):
In short without our code:

CODE

Device (AGP) (Dispositivo madre)

{

Nombre y dirección.

DEVICE VID0 (Dispositivo hijo)

{

   Nombre y dirección de VID0

Inicio del método

{

   Método

   }

   Device (TV)

Device (CRT)

   Device (LCD)

Device (DVI)

}

}

Briefly our code:

CODE

{

{

   Nombre y dirección de VID0

Inicio del método

{

motherboard manufacturer, but sometimes we do not see the device with a clear demarcation in ioreg and appears as PCI2BRIDGE or in this case PCIBRIDGE
add the entry directly into the ICP as all these devices have the device "mother" to the main PCI ..... In plates with integrated graphics
we can find something closer to the example of the laptop, but we must not fall into errors, the code must be added in the code
for the device that is located not on our card and the integrated video board.

Set in the PCI code.

5. Compiling and testing.

Now we only save the file and compile it to check for syntax errors or not.
Open the terminal, as root logueamos us and tune into the folder where we have our DSDT (cd "path to folder") Keyboards
iasl dsdt.dsl

If errors occur is that you put the wrong charger, if warnings occur, is that it may come before, not do them much attention now.
If you have them, make certain that brackets have not been orphaned, or deleted.
If not, you can rename the file you have in DSDT.aml the root of the system to "DSDTold.aml" and copy the new (to open created when compiling) to the root of the disk.
We delete the injector that we are using (Nvkush, Nvinject or NVdarwin) or EFI string if we use this method and proceed to reboot. If our site has
been right and proper coding of our graphics should be fully recognized and activated yet.
If you fail the new DSDT.aml (eg freezes the system), you can boot the system using the command DSDTold.aml DSDT = (introducidlo when you see the boot
chameleon by pressing F8 and selecting the installation of Leopard).
We hope that this third guide on the possibilities of DSDT system has been of your liking.
We will be updating the guidelines as new data have ....

ANNEX

In this annex, see how to optimize a laptop, removing the graphic code is not used by OSX, obtaining with this a greater fluidity in the video
because the register is only the code that is functional, our code added.
In the summary view can better see the tree of devices, so we can determine who should stay and who must not be erased to useful code and
prepare for the inclusion of our code of video.
In summary, our code should look like in after deleting unnecessary devices:

Obviously, if we are to compile after erasing all those devices, we report a number of errors will disappear as many references as well
that we look for the lines marked as errors and remove them as follows:

CODE

Errores generados al compilar cuando eliminamos el device "LCD":

/Users/xxx/Desktop/pruebas dsdt/Tools/DSDToriginal.dsl 721: Notify (\_SB.PCI0.AGP.VID.LCD, 0x86)

Error 4063 - Object does not exist ^ (\_SB.PCI0.AGP.VID.LCD)

/Users/xxx/Desktop/pruebas dsdt/Tools/DSDToriginal.dsl 726: Notify (\_SB.PCI0.AGP.VID.LCD, 0x87)

Error 4063 - Object does not exist ^ (\_SB.PCI0.AGP.VID.LCD)

We move to the line 721 and 726 as shown and we find:

CODE

If (LGreaterEqual (OSID (), 0x20))

{

If (And (Local0, 0x04))

{

Notify (\_SB.PCI0.AGP.VID.LCD, 0x86)

Notify (\_SB.PCI0.VID.LCD, 0x86)

}

If (And (Local0, 0x02))

{

Notify (\_SB.PCI0.AGP.VID.LCD, 0x87)

Notify (\_SB.PCI0.VID.LCD, 0x87)

}

}

If we remove those two entries, and compile again, the errors are gone.

CODE

If (LGreaterEqual (OSID (), 0x20))

{

If (And (Local0, 0x04))

{

Notify (\_SB.PCI0.VID.LCD, 0x86)

}

If (And (Local0, 0x02))

{

Notify (\_SB.PCI0.VID.LCD, 0x87)

}

}

It is recommended to compile every time you delete an entry, so you can gradually correct our code.
