[gentoo-user] I915 mobile firmware

[gentoo-user] I915 mobile firmware

[Peter Humphrey]

Hello list,

My new laptop shows this from /proc/cpuinfo:

--->8
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 154
model name      : 12th Gen Intel(R) Core(TM) i7-12700H
stepping        : 3
microcode       : 0x421
--->8

I've been hunting around to find which modules I need to load from sys-kernel/
linux-firmware, and it isn't at all clear.

Some sources say that the processor is a mobile complement to Alder Lake 11th 
gen, but I also see it as just Tiger Lake. The web seems full of helpful 
information, but not quite helpful enough for me.    :-(

-- 
Regards,
Peter.

Install lshw - might give more info.

Boot off of an install, ubuntu, sysrescue or other live USB and 
investigate dmesg.

And lsusb, lspci,..(I think they're both readily available)

lsusb won't offer much info on a CPU ...

lscpu should be more appropriate.

Intel's website mentions this 12th Gen CPU was *formerly* known as Alder Lake, 
was released in Q1 2022, but does not make it clear what it is now named as:

https://www.intel.co.uk/content/www/uk/en/products/sku/132228/intel-core-i712700h-processor-24m-cache-up-to-4-70-ghz/specifications.html

So, I'd be inclined to take their word for it.  This Wikipedia lists the 
processor as a mobile Alder Lake:

https://en.wikipedia.org/wiki/Alder_Lake#Alder_Lake-H

The Tiger Lake processors are 11th Gen and their model numbering start with 
11***.

This page also confirms your family and model number as per cpuinfo use the 
Golden Cove (P-cores) microarchitecture:

https://en.wikichip.org/wiki/intel/microarchitectures/alder_lake#CPUID

sys-apps/dmidecode will provide additional information to determine the 
specifics of what the MoBo firmware reports.
