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

langht said:
Help me, what do I open and edit these patchs. I began to meet lags when login. My Cpu is Haswell.

Sorry, I already fix this problem.
 
I have managed to install Sierra on my HP AC-184-TU Laptop with HD5500. I am using rehabman's config.plist for HD5500 and successfully managed to install the OS. After installation I CAN boot into it only under safe mode. Otherwise I get kernel panic when trying to boot with the clover installer USB, as shown on the screen. Attaching my USB EFI folder. Can someone help me?

that has to do with incorrectly set DVMT-prealloc can you change that in your BIOS to 96mb or higher? 64mb may work

My DVMT is 192 MB (checked from windows).

windows is not the best way to check that (it is written in the clover guide)

I am using a patched AppleIntelBDWGraphicsFramebuffer kext and using "inject ig-platform-id" method to get over the stolen memory problem. Is this not supposed to work?

This is it!
My u430 with 10.12.4 suffered from this problem (short duration lag after wake and after login).

My u430 has LVDS and a single HDMI.
I use ig-platform-id 0xa260006 with it. 0xa260006 has LVDS, 0105 DP, 0204 DP.
The HDMI is wired to 0204, so I patch that port for HDMI (to enable HDMI audio).
I also use the 'vbo' 9mb cursor bytes patch (even though it is not needed on my particular laptop... it is helpful on others).

So... before 10.12.4, I had these patches for com.apple.driver.AppleIntelFramebufferAzul:

Comment: 0x0a260006 9MB cursor bytes, vbo
Find: <0600260a 01030303 00000002 00003001 00006000>
Replace: <0600260a 01030303 00000002 00003001 00009000>

Comment: HDMI-audio, port 0204, 0x0a260005 0x0a260006
Find: <02040900 00040000 87000000>
Replace: <02040900 00080000 87000000>

Now the 0105 port comes before the 0204 port in the framebuffer, but we don't need the 0105 port as it is not connected to anything (and causing the lags).

So... strategy is to replace 0105 with 0204 and reduce the number of ports from 3 to 2.

We already know that in AppleIntelFramebufferCapri that 0x01660004 has only a single LVDS connector, so we can look to the header of that ig-platform-id data to discover what we need to reduce our ig-platform data in Azul from 3 ports to 2.

From AppleIntelFramebufferCapri 0x01660004:
04006601 01030101

And from AppleIntelFramebufferAzul 0x0a260006:
0600260A 01030303

So, there appears to be two counts at the end related to the number of connectors... plan to change them both...

New set of patches:

Comment: 0x0a260006 9MB cursor bytes (vbo), 2 ports only (RehabMan)
Find: <0600260a 01030303 00000002 00003001 00006000>
Replace: <0600260a 01030202 00000002 00003001 00009000>

Comment: 0x0a260006 disable 0204 port, change 0105 DP port to 0204 HDMI (RehabMan)
Find: <01050900 00040000 87000000 02040900 00040000 87000000>
Replace: <02040900 00080000 87000000 FF000000 01000000 40000000>

Result: No more lag after login and wake from sleep.
