0xa260006 requires 32mb.
Set to 32mb.
Remove or disable the 128mb patch in your config.plist.
Enable the 9mb cursor bytes patch.

Don't forget to re-extract/re-patch ACPI after changing it.

I only have the option for 128mb or 64mb in my bios.

Set to 64mb and try 0xa260006 (with 9mb cursor bytes patch) or 0xd260007.
Don't forget to re-extract/re-patch ACPI.

_REG->XREG patch is a huge mistake.

Just wondering how I should change this?

I notice in your Lenovo-Z50 repo the patch is slightly longer, but I still have multiple _REG methods, and don't want to overwrite them.
This is the method that needs to change:
Code: 
Method (_REG, 2, NotSerialized)  // _REG: Region Availability
{
    If (LEqual (Arg0, 0x03))
    {
        Store (Arg1, ECFL)
    }
}
Should I write the patch like 5F52454702 -> 5852454702 as it is in the Lenovo repo, or extend it to 5F52454702A00B93680A03 -> 5852454702A00B93680A03?

Also, should I change the corresponding _OFF -> XOFF patch?

You need to grab some bytes from the method definition so that your find pattern is unique and specific to that _REG method. Use a mixed listing of the .aml (iasl -dl -l DSDT.aml) so you can see the bytes that surround that method.

Read the guide:

Okay so I should use 5F52454702A00B93680A03 -> 5852454702A00B93680A03. Am I correct in assuming that the same goes for the _OFF method?

You have to look at the bytecode in your native DSDT to decide.
 
plasmaboltrs said:
Yes that is the bytecode from it.

Assuming it matches, then looks ok.
It is a judgement call as to how many bytes you need to include in the find pattern.
One one hand, more bytes from the method code results in less chance of a false positive with some other _REG.
But on the other, more bytes results in less chance of it matching against the target _REG in the case of a BIOS update that changes the code slightly.
 
Okay I've made all the changes you suggested.

Using 0x0d260007 caused the graphical glitches to be much stronger, and basically make the laptop unusable, so I had to switch back.

Just wondering if you've got any other suggestions for me to fix, and also any ideas on how to stop the flickering/boot glitch.



Here's a fresh set of the commands, ioreg, and clover folder. I've also done the patchmatic thing.

Here is what I've tried so far:

CSM on / off - glitches
Using platformID 0x0a260006 or 0x0d260007 - glitches
Using platformID 0x0d220003 + Inject EDID - no glitches, but no brightness control
Using platformID 0x0a260006 with reduced resolution 1600x900 - no glitches
IntelGraphicsFixup.kext fixes scrambled screen at boot, but there are still glitches at runtime
