Is DTGP required on hotpatches?

[sakoula]

Hi,
I have noticed that many hotpatches include External (DTGP, MethodObj) such as SSDT-RMNE.dsl. Do they require the DTGP patch? If yes why is that.

for example SSDT-RMNE.dsl at RehabMan's site does not include the DTGP method/patch

Thanks!

Hi,
DTGP method is not required in SSDTs necessarily. I guess the method is only used to check UUID, and a piece of generic code is injected into our DSDT. In Rehabman's repo, he uses
If (!Arg2) { Return (Buffer() { 0x03 } ) }
to replace DTGP method, which is good and simple.

The reason I use DTGP method is that many real MacBookPros use that. I want our devices behave more natively. Here are two DSDT examples from MacBookPro14,1 and MacBookPro14,2 and you can see that almost every _DSM method followed by a DTGP method.(Please don't share, these files are just for hackintosh study!)

Hi, Thanks a lot for you super detailed reply. Actually I have a Xiaomi Mi Notebook Air 13.3'' (i5 6200U) and I am trying to learn while converting it to a hackintosh! The XiaoMi-Pro repository is an amazing knowledge treasure for me. Well done!!!

May I ask a couple of questions?

1. How did you make the CPUFriendDataProvider for the Pro? Can you point me to some documentation/thread to start experimenting with (my battery life sucks). Does it make sense to install the Pro provider? I assume that it is a totally different architecture and will not be compatible.

2. I have big trouble with VoodooI2C. How can I tell the type of touchpad that I have? What tools are you using in Windows to see details of the devices? I cannot see the I2C devices under ioreg by no means.

Sorry for all these questions!

Thanks! and Happy new year!

Happy new year! I am glad that you like my work.

1. I think you need to generate an unique CPUDataProvider because you have a different generation CPU. Full instruction is at:https://github.com/acidanthera/CPUFriend/blob/master/Instructions.md
   I have explained my process before at 10th floor in #22, which may help you.
   A easier way is to choose a compatible SMBIOS and check plugin-type in config.plist

2. For VoodooI2C, full instruction is at here. You can go to Device Manager and find your trackpad.
