Disabling the MHI M2 state appears to completely resolve issues where
enabling the wifi firmware would cause the the whole system to freeze
quite frequently. The reason for why this fix works so well is still
unknown and under investigation. See some discussion here:
http://lists.infradead.org/pipermail/ath11k/2020-December/000876.html
Also renames the firmware package to clarify that it is for the wifi
driver. This is to avoid confusion with the bluetooth firmware which
will be added in an upcoming patch.
Here's a link to kvalo's branch with the kernel patches:

The patches are based on version 5.10-rc4 of linux, so you'll want to
use `linuxPackages_testing`.
trace: warning: The option `i18n.consoleFont' defined in
`/nix/var/nix/profiles/per-user/root/channels/nixos-hardware/dell/xps/13-9360'
has been renamed to `console.font'.
1 default one, with nvidia working and intel working, needs optirun to
run application with nvidia
2 intel only, I am using this as my daily driver for long time, only
intel is turned on and nvidia is turned off and doesn't drain any
power.
3 nvidia only, intel is dissabled and nvidia is picked as default gpu,
no need to fiddle with optirun etc, good for gpu heavy application.
All these settings needs to reboot to work properly
This is pretty much a copy of XPS 9370, without kaby-laky and the throttle bug. I was getting lockups with the kaby-laky changes and the throttle bug did not seem to have an impact either way.
Enforce proper naming: all paths are lowercase and hyphen-separated,
if there's a line of models (aspire, macbook-pro, thinkpad) it becomes
a subdirectory. Documentation for profiles is moved to README files in
respective directories.
Add an Org mode table that lists all available profiles and their paths.
Instead of fetching repo locally, use a Nix channel. Making hardware
profiles read-only should improve quality and amount of participation
long-term.
hardware-configuration.nix is still relied upon for hard drive
configuration, and it handles variations of hardware (custom
configurations, subrevisions).
