hi all, i have couple of kernel modules that need to be ported to 64bit (x86_64) architecture. userland binaries are built in 32bit mode (for historical reasons), and interact with the kernel module using ioctls. i understand that for reading/writing lp64 data types, a translation function need to be registered with the kernel. what about the ioctls that i know don't require any translation ? it seems that i _still_ need to provide sys_ioctl (as the default handler) for all such ioctls explicitly. apparently in x86_64/ia32/ia32entry.S, compat_sys_ioctl is the only function defined (to handle ioctls), which does require some handler to be present. is there a better way to handle this ? thank you kind regards anupam -- Kernelnewbies: Help each other learn about the Linux kernel.
