Hi again!

I posted a while back with issues with my display flickering, and with help managed to solve that. Now I'm back again, mainly out of curiosity, as my iGPU (an Intel HD 4600, assumed mobile, with 1.5 or 2.0GB VRAM, not sure) is recognised as an Intel Iris Pro, with only 1024MB VRAM.

I'm just wondering if there's anything I can do to fix this, or not...

Here's the output of the requested commands:
Code:

I've attached my clover folder, patchmatic output, and ioreg.

Thanks in advance,
Zach

It is as expected with ig-platform-id 0x04260000.
The VRAM amount is coded into the ig-platform data.
You could patch it for more or use a different ig-platform-id that has more.

Thanks for the quick reply!

Is there a list that shows how much VRAM each one has? Or any particular one you'd suggest trying?

From my trials so far, 0x04260000 was the only ID that didn't cause screen flickering...

Any suggestions on how I may patch it? Ideally via Clover if that's possible...

Thanks!

You can look at the framebuffer kext binary and discover each ig-platform-id and the respective DVMT-prealloc, VRAM, cursor bytes, framebuffer size, connector types, PWMMax values, etc.

Any suggestions on how I may patch it? Ideally via Clover if that's possible...

You would need to do some reading about patching the framebuffer.
You can get DVMT-prealloc/VRAM/cursorbytes/framebuffer size data from another ig-platform-id (such as 0x0a260006) to use as an example.

Pike R. Alpha has some scripts that can extract the framebuffer data and display it. Great learning tool if you're not comfortable with a hex editor.

For example, compare 0x04260000 header data against 0x0a260006:
0x04260000:
00 00 26 04 00 03 03 03 00 00 00 04 00 00 00 01 00 00 F0 00 00 00 00 40

0x0a260006:
06 00 26 0A 01 03 03 03 00 00 00 02 00 00 30 01 00 00 60 00 00 00 00 60

Hi again!

Thanks very much for the info, I found a post by Herve on another forum that broke down the hex data, explaining what each bit meant, and from that managed to write a patch to set my VRAM up to 2GB.
