CorePure64 17 won't boot on Dell Pro Max with Intel Core Ultra 5

[nick65go]

I will close my comments here, because the subject is about gpu-id=7D67.
But because I have a gpu-id=A7A1, I am interested in TC original version to be successfully for my laptop model, which I intend to keep another 6 years (at least). 

So to summarize:
1. firmware for xe (files from /usr/local/lib/firmware/xe) are not always in need (at lest for my CPU)
2. firmware for i915 are in need (seen from dmesg)
3. GPU driver named i915 must be forbid / blacklist as early as possible at booting -- kernel parameter
4. GPU driver named xe must be force probed as kernel parameters.
5. xe driver depends on kernel module configfs.ko (thanks Juanito to highlight this!) https://docs.kernel.org/gpu/xe/xe_configfs.html

for TC17 is in https://mirrors.dotsrc.org/tinycorelinux/17.x/x86_64/tcz/filesystems-6.18.2-tinycore64.tcz.tree
For my kernel was already built-in

firmware-i915 updated, firmware-xe added, both in the tc-17.x x86_64 repo

[Juanito]

...and, with the updated firmware-i915 (?!) things work.

Bizarrely, when graphics-KERNEL is loaded, both i915 and xe kernel modules load.

Bizarrely, when graphics-KERNEL is loaded, both i915 and xe kernel modules load.

there are my additions against i915 loading, both in grub.cfg: 
for grub2: modprobe.blacklist=i915 (on one individual line)
and for kernel: module_blacklist=i915 xe.force_probe=a7a1 i915.force_probe=!a7a1 (on another/kernel line)
