kernel 6.10.2-1-siduction-amd64: fails to built nvidia modul for nv470

[michaa7]

Hi towo,

the new kernel fails to built the nvidia modul for nv470. I dont't know how to filter /var/lib/dkms/nvidia-tesla-470/470.256.02/build/make.log for usefull  info as

"cat /var/lib/dkms/nvidia-tesla-470/470.256.02/build/make.log | grep -i error" finds dozens of "-Werror" which seem unrelated.

Please let me know which info you need and how to filter  it.

Thanks for your work.

As you have probably done, I had to boot with the older kernel.

Some things that might be relevant are -

with lots of

warning: suggest braces around empty body in an 'if' statement [-Wempty-body]

Generally when these things have turned up before, it's just a question of staying with the old kernel for a while (for someone like myself who wouldn't have a clue how to fix things).

[ro_sid]

This kernel also fails building the (Siduction's) nvidia-current driver (or the driver with the kernel ).
The previous (6.11) kernel did not!

[towo]

I have uploaded a patched nvidia-470 driver to our fixes repo. Please test it, since i can't without owning nvidia hardware.

Thanks for trying.

As well as the -Wempty-body warnings, there's

Hi towo,

danke!

full-upgrade mit gefixtem nvidia-470-driver + modulbau + reboot in Graphikmodus funktionieren!

Super Arbeit, Danke wie immer für deinen Einsatz.

@ pip

did you update the driver? And BTW, I don't have the directory you mention:

I did a full-upgrade after an update. Do I need to get something from elsewhere too?

[michaa7]

do you have the siduction fixes repo enabled?

Show the apt command and the error in the output

[ro_sid]

The (Siduction-)nvidia-current = nvidia-driver (550.100) driver now compiles with the kernel 6.9.11 as well as 6.10! @towo: Thank you very much.

Thank you! Lots of nvidia-tesla-470 packages today an it's gone through without errors.
