what is _UID in SSDT-PNLF.dsl and how is it used?
I'm using ig-platform-id: 0x0d260007 for my HD4600, as the ports definition best suits my laptop (4 ports in total including internal display)
as per guide, I'll need to set LMAX accordingly, thus 0x7a1
Code:0700260d 01030403 00000004 00002002 00005001 00000060 a1070000 a1070000 00000000 00000000 00000800 02000000
however, I noticed, in SSDT-PNLF I had to change _UID to 15 (the same as default for Haswell) instead of 17 originally, otherwise no brightness slider for me.
(see the end of file https://github.com/1and1get2/CP65S/blob/master/DSDT_NEW/hotpatch/SSDT-PNLF.dsl)
I did google around however nothing was found relating to the usage/purpose of _UID, and nothing in AppleBacklightInjector.kext either
SSDT-PNLF calculates _UID automatically.
Don't forget to set RMCF.LMAX to 0x7a1 as per guide.
