Hi Thomas, thanks for series! I was able to test it on the Steam Deck
(on top of 6.4-rc2), and everything is working fine; also tested S3
suspend/resume, working as expected.
Some logs from boot time:
Parallel boot
[ 0.239764] smp: Bringing up secondary CPUs ...
[...]
[ 0.253130] smp: Brought up 1 node, 8 CPUs
Regular boot (with cpuhp.parallel=0)
[ 0.240093] smp: Bringing up secondary CPUs ...
[...]
[ 0.253475] smp: Brought up 1 node, 8 CPUs
Feel free to add (to the series):
Tested-by: Guilherme G. Piccoli <gpiccoli@igalia.com> # Steam Deck
Cheers,
Guilherme
