You need vfree only if you have allocated donnee using
Generally, your video will screw up. You could solve the problem by running a headless

Hi, thanks for your reply.
I have use ioremap realize the share memory in rt kernel.
Anyway, I think it's better to use ioremap in kernel mode, since we can

Hi Tomek,
mmap and other posix file functions are supported in rtl_posixio.o,
