How to get BIOS Device Name from Linux, same as Windows Device Manager format

My laptop has a display adapter and from Windows 10 I can see its BIOS Device Name from..

Device Manager > Display Adapters > Properties > Details > "BIOS device name"

And from there I get a pop up window saying something like: \_SB.PCI0.GFX0

How can I get that information if the same laptop is running Linux?

Cheers

Update

I need this information because I am building a hackintosh and need to build a SSDT to create a display backlight fix. I would like to help out at the Opencore project and provide a method to do this in Linux as currently the only method is to switch in to Windows and use Device Manager

I tried dmidecode and lspci and they don't give me a BIOS device name in the format that Windows does and is needed to create the SSDT.

I tried acpidump and it's getting me closer but the decompiled output has disassembly errors. It contains the string I am looking for \_SB.PCI0.GFX0 but I don't know how I would create a script to read that file and correlate it to my particular display adapter. e.g: Intel(R) HD Graphics 4000.

These are the commands I have tried so far with acpidump
I dump the ACPI tables from my system to a text file:

sudo acpidump -o acpidump.out

Extract the binary ACPI tables from acpidump output

acpixtract -a acpidump.out

I now have seven ssdt*.data files. I disassemble the binary table of ssdt1.dat into human source

iasl -d ssdt1.dat

This gives a large .dsl file, this is just the first 60 lines of over a thousand..

I think maybe I need to dissasemble ssdt1.dat such that I don't get disassembly errors and then is there a way to search that disassembled file for a device by a name like 'Intel(R) HD Graphics 4000' or that would at least be obvious this is the BIOS Device Name for my display adapter?

Maybe dmidecode, lspci and acpidump can all be combined into a script?

Any other help much appreciated.
