Hello!
These patches a refresh of the series adding support for final stages of the
GSP boot process where a sequencer which inteprets firmware instructions needs
to run to boot the GSP processor, followed by waiting for an INIT_DONE message
from the GSP and finally retrieving GPU information from the GSP.
The patches are based on Alex's github branch which have several prerequisites:
Repo: https://github.com/Gnurou/linux.git Branch: b4/gsp_boot
The entire tree (these patches + patches from Alex, Alistair, John) can be
found at the git repository:
git: git://git.kernel.org/pub/scm/linux/kernel/git/jfern/linux.git
tag: nova-sequencer-init-done-v3
I also dropped several patches (mainly from John that have already been
applied). Tested on my Ampere GA102 and I see in dmesg:
NovaCore 0000:00:07.0: GPU name: NVIDIA GeForce RTX 3090 Ti
Changes from v2 to v3:
- Added several tags.
- Fixed commit messages, style errors.
- Added GspStaticInfo patch.
- Fixed bug found by Timur in the sequencer code (related to ignoring messages).
- Removed excessive dev_dbg prints in sequencer code (John Hubbard).
