[README] Common (some unsolved) Problems in 10.12 Sierra

I have a similar issue (lag on startup/wake) with my setup, but my laptop has Broadwell using ig-platform-id 0x16160002. I'm guessing I would have to patch AppleIntelBDWGraphicsFramebuffer to disable the unused ports (my laptop has mini-DP and the built-in display), but I don't really know where to begin.

Yes... same process as I did for Azul, but get patching a different kext.
The ig-platform data is very similar between all the Intel graphics framebuffer kexts.

Gave it a shot and patched the port numbers and removed/changed the port the same way you did for the Azul framebuffer. The outcome was interesting. Definitely no lag on boot, so that's great. But backlight control (using AppleBacklightInjector) stops working when I use the patches, and the display doesn't wake after sleeping.

No idea what you did without "Problem Reporting" files...

Read FAQ, "Problem Reporting"

I've attached the problem reporting files. Thank you.

You are using ig-platform-id 0x16160002. 0x16160002 uses a PWMMax of 0x65c, not 0xad9. As mentioned in the backlight guide, it means you have to either set LMAX to 0x65c (in SSDT-Config.aml). Or you can patch the framebuffer to change the PWMMax in 0x16160002 from 0x065c to 0xad9.

For example, you could use this patch for AppleIntelBDWGraphicsFramebuffer to change the PWMMax used:
Find: <6C 05 00 00 6C 05 00 00>
Replace <d9 0a 00 00 d9 0a 00 00>
 
Updating to 10.12.5 seems to have given me back control of backlight settings on my HP 4330s Probook (the thing that had broken down on 10.12.4, which I hadn't fixed manually).

Can anybody else confirm that?
