compile issues

[temporary999]

Hello
I have fixed the  drm_prime_sg_to_page_addr_arrays issue by "https://github.com/Xilinx/XRT/issues/5943"'s hint.

Now I have this pointer issue

make CHECK="/usr/bin/sparse" -C /lib/modules/6.0.2-zen1-1-zen/build M=/home/user/dev/git/fl2000_drm modules
make[1] : on entre dans le répertoire « /usr/lib/modules/6.0.2-zen1-1-zen/build »

Thank you again :)

I have fixed the pointer .. kinda,
but it seams now that the DRM interface is not compatible with kernel post 5.11 or 5.18 .

best regards

How did you fix them ? :)
I'm also trying to make it work (under kernel 5.15)

I hunted down the C language errors, that is standard&classic, as said it didn't work anyway ...
we can do nothing without a real Linux driver developer
And
follow the kernel's architecture to update it correctly ...

Hi Remi,

This fork seems to add VGA support and newer kernel support :)
https://github.com/rhgndf/fl2000_drm

I can compile it, but no way to "insmod" it into the kernel.

[remi75]

have you filed a bug report ?
last work 2 weeks ago, that is very promising ! thank you for spotting it

[bigrck64]

Yes I created the first issue there :)
