Tips for building hex device path.

for example your devpath in ioreg:
IOACPIPlane:/_SB/PCI0@0/P0P5@1c0001/ethernet@0
How to convert it to hexadecimal efi devicepath?
It easy
Follow my guide:

1. ROOT PCI BRIDGE node. ACPI Device Path _HID PNP0A03, _UID 0. ACPI name space \_SB\PCI0. Shorthand notation is ACPI(PNP0A03,0)

• from ioreg: find _SB/PCI0@0 or similar (if there is PCI1@0 or similar then you probably have to change UID part)
• into efi: 02010c00d041030a00000000 (last 4 bytes are UID, if in system are two dev with same HID then system inc UID, if you want set UID = 1, then change last 4 bytes 01000000)

2. first PCI DEVICE node. Shorthand notation is PCI(1c|1)

• from ioreg: find _SB/PCI0@0/P0P5@1c0001 or similar
  P0P5@1c0001 -> add leading zeros POP5@001c0001
  POP5@xxxxyyyy
  xxxx - pci device
  yyyy - pci func
• into efi: 01010600011c (pci node is like that 01-hardware path type, 01-pci device type, 0600 - length, 01 - pci function (1 byte), 1c - pci device (1byte) )

3. second PCI DEVICE node. Shorthand notation is PCI(0|0)

• from ioreg: find _SB/PCI0@0/P0P5@1c0001/ethernet@0 or similar
  ethernet@0 -> add leading zeros ethernet@00000000
  ethernet@xxxxyyyy
  xxxx - pci device
  yyyy - pci func
• into efi: 010106000000 (pci node is like that 01-hardware path type, 01-pci device type, 0600 - length, 01 - pci function (1 byte), 1c - pci device (1byte) )

4. Device path end node.
into efi: 7fff0400

5. put these parts together and
from: IOACPIPlane:/_SB/PCI0@0/P0P5@1c0001/ethernet@0
into: 02010c00d041030a0000000001010600011c0101060000007fff0400

I wanted to give this a try so I could eliminate the patched IONetworkingFamily.kext but I can't locate any of the search strings you referenced in your guide.  I have an after market PCI 10/100/1000 ethernet card in one of my two PCI slots. The other slot has my Nvidia GFX 5500 video card. Both cards are plugged into a riser card which is inserted into the mother board.  IBM did this to make a low profile system unit.

When I scan the ioreg DeviceTree dump I only see one reference to ethernet which does not appear to be related to the search strings in the guide.

I made a device tree dump using the stock 10.5.1 IONetworkingFamily.kext.  I would appreciate any suggestions on how to proceed. I don't understand how to map what I see to the parts of your guide.

The full devicetree dump is attached below along with an extracted dump which just contains the part of the tree related to the ethernet card.

Thanks. BladeRunner

Try these paths: Acpi(PNP0A03,0)/Pci(0x1e,0)/Pci(0,0)/Pci(0,0) or Acpi(PNP0A03,0)/Pci(0x1e,0)/Pci(0,0)

Try these paths: Acpi(PNP0A03,0)/Pci(0x1e,0)/Pci(0,0)/Pci(0,0) or Acpi(PNP0A03,0)/Pci(0x1e,0)/Pci(0,0)

I tried using the latest version of gfxutil (0.6b) but it kept crashing using the device paths you suggested. So, I tired the two you gave as examples in the first post. The one which begins "PciRoot(0x0)/P" works and produces a hex output file. The other example, which looks like the two you suggested I try, failed with the following error:

bash-3.2# ./gfxutil -v -s -n -i xml -o hex ./timeMachine.plist ./timeMachine.hex
GFX Data: filesize=56
GFX Data: numofblocks=1

 Header: blocksize=44
 Header: records=1
UnpackDevicePath: Probably a bogus device path
Assertion failed: (UnpackDevPath != NULL), function ConvertDevicePathToText, file /Users/fox/Desktop/Projects/gfxutil/efidevp.c, line 1039.
Abort trap
bash-3.2#

Both of the strings you suggested for me failed with the same error.

I have attached the input ./timeMachine.plist file. Please tell me if I am using gfxutil incorrectly or the input plist file is bad.

New fixed version 0.65b is available!

Your devicepath syntax is a bit wrong:
<key>ACPI(PNP0A03,0)/PCI(1e|0)/PCI(0|0)</key>
gfxutil will accept following syntx
<key>ACPI(PNP0A03,0)/PCI(0x1e,0)/PCI(0,0)</key>

Please try and give feedback!

[BladeRunner]

I tried the new version - with corrected syntax - and it worked. I used the device path in your previous post and also switched to the new true/false tag. The output below is from that test.  Now I just need to see if it works to fix the TimeMachine problem for me.

Code:

bash-3.2# ./gfxutil -a
./gfxutil Version: 0.65b by McMatrix
bash-3.2# ./gfxutil -v -s -n -i xml -o hex ./timeMachine.plist ./timeMachine.hex
GFX Data: filesize=75
GFX Data: numofblocks=1

 Header: blocksize=63
 Header: records=1
 Header: hex devicepath =<02010c00d041030a0000000001010600001e0101060000007fff0400>
 Header: txt devicepath=PciRoot(0x0)/Pci(0x1e,0x0)/Pci(0x0,0x0)
  Setting: built-in=0x01

By the way, many thanks for the GREAT utility.

No luck here... See the acpi-path on the atached img.. for that i,ve used:
   
     ACPI(PNP0A03,0)/PCI(0x1b,0)/PCI(0,0)

But then the tool says:

    Header: txt devicepath=PciRoot(0x0)/Pci(0x1b,0x0)/Pci(0x0,0x0)

Acpi its the same as PciRoot? because dont matter i use ACPI, the tool converts it to PciRoot...

Also i've tested without the Last PCI(0,0) and still the tool convert to PciRoot...


Also, why not use IORegistryExplorer/IODeviceTree format as input?

[krijonk]

Ok, I have tried reading through this long enough, I just can't seem to get it....

If somebody wants to take a shot at converting this EFI device path to HEX, feel free, it will be much appreciated.

Need your full IODeviceTree dump.

ioreg -l -w0 -p IODeviceTree >dump.txt

ACPI(PNP0A03,0) is yor pciroot!. Pciroot(0x0) is just alias for ACPI(PNP0A03,0).
So this is not a case.

Need your full IODeviceTree dump:

ioreg -l -w0 -p IODeviceTree >dump.txt

Here is my IODeviceTree Dump:

I also can't seem to get gfx-string working for 7300GS, even using a reported "working" string from this forum for the EXACT same card i have (Gigabyte 7300GS 128MB).

I appreciate all the help you can offer....

Here is my IODeviceTree Dump:

Your device path is _SB/PCI0@0/P0P2@10000/Display@0. Shorthand is:
PciRoot(0x1)/Pci(0x1,0x0)/Pci(0x0,0x0)
...so <key> string should be?
02010c00d041030a000000000101060000010101060000007fff04001

Your best bet is to download mcmatrixs' util, convert a working string to xml, edit device path key, then convert back to hex. While you're editing, you should also change device property keys to match those in your IOReg (like NVCAP, address cells, etc..)

No his pciroot is pciroot(0x0) because PCI0@0 _UID = 0

Oh! My bad. But I believe in spite of my fat finger, the <key> string is still correct?
