Maybe just cuse_lowlevel.c, maybe kernel too.
A patch had been submitted some years ago, more than once, asking for

A simple (but ugly!) approach would be redirecting mmap() requests on CUSE
devices to /dev/mem.
hmm?
what requests are you talking about given that at the moment the CUSE
client interface (cuse_lowlevel_ops) does not expose mmap?

for example, many existing video applications use mmap() to map the

Hi guys,
a bit OT probably: is there any chance for you to also implement mmap()
for CUSE? That would be much appreciated.
Thanks

Hi Andrew,
I was wondering if there's a chance to have this patch merged anytime
soon. Note that FUSE maintainer left off sometime ago and there's no one
taking care of kernel patches at the moment.
Please let Jader and me know if there are any problems.
Thanks

Hi people,
we properly submitted some kernel patches (adding mmap support to CUSE)
to the FUSE mailing list some months ago and have been asking for their
inclusion in the FUSE tree since then, but got no feedbacks, no replies
at all from the maintainers. We would like to have these patches

through ioctl()? It's not as immediate and safe as controlling the device
registers through /sysfs (not /proc). However, the sysfs interface in those
drivers appeared before V4L2 h
() supersedeing sysfs in this case?
