Subject: Re: [PATCH v12 00/11] Parallel CPU bringup for x86_64

Hi Usama and David, thanks for the great series!

I've tested it on Steam Deck (with and without the "no_parallel_bringup"
parameter), it works fine - also tested S3/deep sleep-resume cycle.

Feel free to add (to the series):
Tested-by: Guilherme G. Piccoli <gpiccoli@...lia.com>

Also, just taking the opportunity since I'm already replying here: on
patch 09, found two typos:

s/correect/correct (commit message)
s/brinugp/bring-up (kernel-parameters.txt)

Cheers,


Guilherme
