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 » CC [M] /home/user/dev/git/fl2000_drm/fl2000_gem.o /home/user/dev/git/fl2000_drm/fl2000_gem.c:273:17: erreur: initialisation de « int ()(struct drm_gem_object , struct iosys_map ) » depuis le type pointeur « void ()(struct drm_gem_object ) » qui est incompatible [-Werror=incompatible-pointer-types] 273 | .vmap = fl2000_gem_prime_vmap, | ^~~~~ /home/user/dev/git/fl2000_drm/fl2000_gem.c:273:17: note: (près de l'initialisation de « fl2000_gem_default_funcs.vmap ») /home/user/dev/git/fl2000_drm/fl2000_gem.c:274:19: erreur: initialisation de « void ()(struct drm_gem_object , struct iosys_map ) » depuis le type pointeur « void ()(struct drm_gem_object , void ) » qui est incompatible [-Werror=incompatible-pointer-types] 274 | .vunmap = fl2000_gem_prime_vunmap, | ^~~~~~~ /home/user/dev/git/fl2000_drm/fl2000_gem.c:274:19: note: (près de l'initialisation de « fl2000_gem_default_funcs.vunmap ») cc1 : certains avertissements sont traités comme des erreurs make[2]: [scripts/Makefile.build:249 : /home/user/dev/git/fl2000_drm/fl2000_gem.o] Erreur 1 make[1]: [Makefile:1849 : /home/user/dev/git/fl2000_drm] Erreur 2 make[1] : on quitte le répertoire « /usr/lib/modules/6.0.2-zen1-1-zen/build » make: *** [Makefile:23 : modules] Erreur 2

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.

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 :) https://github.com/rhgndf/fl2000_drm/issues/1
