https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206711 --- Comment #3 from Jan Beich <jbeich@FreeBSD.org> --- (In reply to Dmitry Chagin from comment #2) The patch here is the result of failed attempt to register 64bit |struct linux_ioctl_handler| from within nvidia-driver. All in-tree kernel modules register only 32bit ioctls, the rest is done by linux64 (drm2, v4l2, consol= e, etc). How do you expect ports drivers to support linux64 without examples? $ nm -A /boot/kernel/*.ko | fgrep ioctl_register_handler /boot/kernel/amr_linux.ko: U linux_ioctl_register_handler /boot/kernel/ipmi_linux.ko: U linux_ioctl_register_handler /boot/kernel/linux.ko: 0000000000009480 t linux_ioctl_register_handler /boot/kernel/linux64.ko: 00000000000093e0 t linux_ioctl_register_handler /boot/kernel/mfi_linux.ko: U linux_ioctl_register_handler /boot/kernel/mrsas_linux.ko: U linux_ioctl_register_handler nvidia_linux.c doesn't have much MD code but the following has no effect ev= en on the hashsum of its object file. --- src/nvidia/nvidia_linux.c~ +++ src/nvidia/nvidia_linux.c @@ -18,13 +18,8 @@ #define LINUX_IOCTL_NVIDIA_MIN 0x4600 #define LINUX_IOCTL_NVIDIA_MAX 0x46ff -#if defined(NVCPU_X86) #include "machine/../linux/linux.h" #include "machine/../linux/linux_proto.h" -#elif defined(NVCPU_X86_64) -#include "machine/../linux32/linux.h" -#include "machine/../linux32/linux32_proto.h" -#endif #include <compat/linux/linux_ioctl.h> --=20 You are receiving this mail because: You are on the CC list for the bug.=
