Dsdt override for eGPU

gnostyk · Dec 31, 2012

Hi I dont understand how to correct the two error "must be multiple of alignment/granularity value" i my dsdt file. Without this im limited to 2GB RAM in my Fujitsu ah531 if i want setup eGPU with working optimus tweak. Sory for my bad english.

Likewise I have similar problem, I have 62 errors upon addition of 'QWordMemory' (64-bit) entry PCI-e space creater code I added which is in the form of (exactly) insert this at line 3433 after TypeStatic)

QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
0x0000000000000000, // Granularity
0x0000000C20000000, // Range Minimum, set it to 48.5GB
0x0000000E0FFFFFFF, // Range Maximum, set it to 56.25GB
0x0000000000000000, // Translation Offset
0x00000001F0000000, // Length calculated by Range Max - Range Min.
,, , AddressRangeMemory, TypeStatic)

I seem not to be any good at getting a succesful compile? sure its just brackets and parses and the like? but I have never used dsdtse editor before so I would appreciate any help to compile the attached file and return the output files by attachment?

I will attach my not so ready to compile file and hope one of you experts can help to return a succesful compile file by attaching the good compiled output files please as us poor win7 mortals cant do it lol, This will then allow win 7 dsdt.aml fix to be loaded and thus allow for the PCI-e bus to allocate sufficient 36bit space for the eGPU to be loaded when booting with >4gb upwards of RAM otherwise the e-GPU is not even detected! method suggested from http://forum.notebookreview.com/e-gpu-external-graphics-discussion/418851-diy-egpu-experiences-894.html#post8377566 my 'in need of correcting' then to compile file is attached. Please help me to compile. :banghead:

Please help me to compile.

Apply these two patches:

Code:

# Fix parse errors
into device label GFX0 code_regex If\s\(CondRefOf\s\(FPED\)\)\s*\n\s*\{\s*\n\s*FPED\s\(\)\s*\n\s*\} remove_matched;

# rehabman:
# _PLD is supposed to return a variable length Package of Buffers

into_all all code_regex (Name\s*\(_PLD,\s*)Buffer(\s\(0x10\)[^\)]*) replaceall_matched
begin
%1Package() { Buffer%2}
end;

You should have clean compile at that point...

:DHi RehabMan. Thank you, I have succeeded in applying your patches and have a error free compile, which after loading the output .aml file into registry gives me a 'Large Memory' as well as 'Memory' section in Device Manager>=Resources by connection>=Memory, This means I now have a 36bit PCI Bus (>0x100000000) Yipppee, prob I have now is I believe I need to find and download a program called Setup 1.11a which will give me ability to chainload and compact and Lockin etc external Gpu to 36bit bus memory allocation space, presently my pc still does not detect the eGPU?? Any idea where I can download this eGPU Setup 1.11a program? and Thank you for your help so far :thumbup:

Dsdt override for eGPU - hp probook 6570b (win7x64)

When I dissassemle I get this error message:

ASL Output: dsdt.dsl - 1013371 bytes

iASL Warning: There were 2 external control methods found during
disassembly, but additional ACPI tables to resolve these externals
were not specified. The resulting disassembler output file may not
compile because the disassembler did not know how many arguments
to assign to these methods. To specify the tables needed to resolve
external control method references, the -e option can be used to
specify the filenames. Note: SSDTs can be dynamically loaded at
runtime and may or may not be available via the host OS.
Example iASL invocations:
iasl -e ssdt1.aml ssdt2.aml ssdt3.aml -d dsdt.aml
iasl -e dsdt.aml ssdt2.aml -d ssdt1.aml
iasl -e ssdt*.aml -d dsdt.aml

In addition, the -fe option can be used to specify a file containing
control method external declarations with the associated method
argument counts. Each line of the file must be of the form:
External (<method pathname>, MethodObj, <argument count>)
Invocation:
iasl -fe refs.txt -d dsdt.aml

Then..after adding :
QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
0x0000000000000000, // Granularity
0x0000000C20000000, // Range Minimum, set it to 48.5GB

0x00000001F0000000, // Length calculated by Range Max - Range Min.

Can anyone help me compile my DSDT? With the addition of the following lines:

QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
0x0000000000000000, // Granularity
0x0000000C20000000, // Range Minimum, set it to 48.5GB
0x0000000E0FFFFFFF, // Range Maximum, set it to 56.25GB
0x0000000000000000, // Translation Offset
0x00000001F0000000, // Length calculated by Range Max - Range Min.
,, , AddressRangeMemory, TypeStatic)

And after compiling, I have 149 errors. From here, I have no idea what do. I don't know what patches I need, and cannot move forward with my process of using my egpu with all these errors. Sorry for the noobish ways, ive never used dsdt editor or have even done stuff like this. any help/advice would be appreciated. I will leave my file in its current state here

You may find this repo useful: https://github.com/RehabMan/HP-ProBook-4x30s-DSDT-Patch
(read the wiki)

Note: Your edit for FPED is incorrect. Fix it and you have zero errors with ACPI5.

I really need help with a DSDT override. I will post my Device Manager with all of my devices (memory). I stayed up all night last night trying to do a DSDT override with no success. I have iasl and asl. I also have a DSDT editor, but I don't know: 1.exactly what to put after Dword 2. How to fix all errors 3. How to get Large Memory to show up in Device Manager. Please someone tell me a specific way to DSDT override that applies to my devices? The eGPU I'm going to use is a Nvidia GT 640. View attachment 163084
