(bug) NVRM kgspInitRm_IMPL: missing NVDEC0 engine, cannot initialize GSP-RM

[kfazz]

The open source KM fails to load for me with the following error:
[ 3.596579] NVRM kgspInitRm_IMPL: missing NVDEC0 engine, cannot initialize GSP-RM

This is on a ubuntu 22.04 system with an RTX 2060, packages are from the cuda apt repo.

After switching back to the proprietary KM using:
$ sudo apt remove nvidia-kernel-open-515 && sudo apt install --reinstall nvidia-dkms-515 && sudo reboot

The proprietary driver loads just fine.

Can you please run sudo nvidia-bug-report.sh and attach the resulting nvidia-bug-report.log.gz file?

[PAR2020]

This is a known limitation of this driver version.
Due to GSP software design, it is required that the NVDEC0 engine is present on chip.
If the engine is not present, it is not possible to boot GSP-RM, as the error message states.
This limitation will be addressed in the next driver release, internal bug 3586266.

Note that this is not related to bug #104 -- NVDEC is supported by the open source driver.
The proprietary driver is not impacted because it does not boot GSP firmware and thus does not rely on NVDEC0.

This should be fixed in 515.48.07. Please let me know if you continue to have troubles. Marking fixed.
