418 drivers unable to build on kernel 5.5

Hello !

Since some time, I saw that branch 418 didn’t have any update, but this is the last branch which supports my GPU (Quadro K1100M).
I need a driver >415 to run specific software, so I can’t go back to 390.X…
I tried to switch to kernel 5.5, and it fails to build the driver with the following error :

/var/lib/dkms/nvidia/418.113/build/nvidia-drm/nvidia-drm-fb.h:30:10: fatal error: drm/drmP.h: No such file or directory
   30 | #include <drm/drmP.h>

I can provide full log if you want, but I already saw some posts on this forum saying that this issue was fixed in recent 440.X drivers

Is there any way to get an “updated” version of the drivers ? Or must I switch back to 390.X drivers ?
(I don’t think applying this patch on 418 drivers would be a “real” solution).

GPU : Quadro K1100M (not supported by 435.X and 440.X)
OS : Debian Testing

Please use the current 440 driver.

Alright, I tried installing 440 drivers, and it works (even if my GPU isn’t in the supported list…).
Why ?

So it means that I should keep updating until I hit a driver version which isn’t working anymore ?

Have an eye on this:

Alright, thank you for your answers !
