Impact: This is a patchset the we (TUXEDO Computers) currently apply on top of the Ubuntu 6.8 kernel to make it run smoothly on all our devices. All patches apply smoothly to 6.8.
Fix: These are all patches already upstream, just not on the 6.8 branch, because they where upstreamed after that one was already EOL.
Testcase: We run this patchset for all our customers devices (we basically maintain our own OEM branch) so it is quite field testet. Besides that, whenever a new patch was added we did regression testing on a selection of devices.
On the TUXEDO InfinityBook Pro Gen9 Intel, a Samsung 990 Evo NVMe leads to
a high power consumption in s2idle sleep (4 watts).
This patch applies 'Force No Simple Suspend' quirk to achieve a sleep with
a lower power consumption, typically around 1.2 watts.
