[Guide] Patching LAPTOP DSDT/SSDTs

[Edoardo001]

I did not spoof it, it is recognized natively. see my config.plist

Scuse me, my bad. I have a Wishkey lake. I have graphics acceleration work perfect. all work fine. But I get a kernel panic at boot and then boot fine. The only way to resolve is to remove, I2C controllers, or to remove OSI to XOSI.
I don't know what to try. I've tried to delete flags and polish config.plist here and there, change some ACPI files,pnlf, DSDT, spoofing a lot of ig-id but nothing to do.

A famous guy of this forum @ben9923 have tried to help me, but maybe. it's too messed. And the thing that make me really frustrated is that I work on it since three days with no sleep with any luck.

and disassmble DSDT.aml into dsl file
then try to fix skl ,skl+ ,they are patched
last to compile DSDT.dsl I got this error.
somebody please help me

This may be a dumb question (I couldn't find the answer elsewhere). But if I'm not injecting kexts (because I'm going to install them in /L/E) then do I need to install this ACPI patch somewhere on the system, or is Clover still going to take care of this part for me from the UEFI partition?

Hi @RehabMan , long time no see
Just dump ioreg from a new MacBook. Found something interesting in PNP0C01 for Haswell/Broadwell graphics:
OS X requires MEM2 instead of TPMX in DSDT. Without patching TPMX in DSDT, PNP0C01 will not be loaded correctly. And so does the IOAccelMemoryInfoUserClient. So, here's the patch I made:

#Credit syscl @ github.com/syscl: iGPU use MEM2 instead of TPMX, and r/w memory instead of r/o memory.
#syscl_iGPU_MEM2.txt

into device label TPMX remove_entry;
into device label PCI0 insert
begin
Device (MEM2) // iGPU use MEM2 instead of TPMX, and RW memory. syscl\n
{\n
    Name (_HID, EisaId ("PNP0C01"))\n
    Name (_UID, 0x02)\n
    Name (_STA, 0x0F)\n
    Name (_CRS, ResourceTemplate ()\n
    {\n
        Memory32Fixed (ReadWrite, 0x20000000, 0x00200000, )\n
        Memory32Fixed (ReadWrite, 0x40000000, 0x00200000, )\n
    })\n
}\n
end;

After applying the MEM2 patch, the PNP0C01 on various laptops will be loaded correctly by OS X, here's the screenshot of the change:

View attachment 200947
Can you upload this patch in your git(so popular) so that more people will benefit from it.
Best wishes,
syscl.

I can't find the difference between renaming and not renaming (No extra driver loading) .

Hi,

Can someone help me patch my DSDT. Here are the laptop specs:

Dell Latitude E6420
Chipset: Sandy Bridge
CPU: Mobile DualCore Intel Core i5-2540M, 3100 MHz
RAM: 16GB DDR3
Video: Optimus - Intel HD3000, NVIDIA NVS 4200M (512 MB)

I have extracted the DSDT with Optimus enabled, which shows both Intel and NVIDIA Cards in Clover. I'd like to disable the NVIDIA card in the DSDT, so that the installation uses the Intel adapter only. Thank you in advance.

If you don't want to use Nvidia, then make sure you have nv_disable=1 in your config.plist. Also in your clover boot up, you need to check the boot arguments. Lastly, make sure you have Intel video enabled in your bios.

I have the NVIDIA Optimus disabled in the BIOS. When I use nv_disable=1 then the system reboots. I guess it causes kernel panic, but it reboots very quickly before I can see what causes it.
