Hi Jan,
as I promised, here is some code for you to look at.

First I will describe the approach in general.

# Get rid of the pipe. Instead, user-space passes a buffer and kernel
fills the specified user-space buffer with commands.
# When the buffer is full, kernel stops generating commands and
returns a checkpoint to the user-space.

Can it just fill a second buffer while userspace command handles the first?

# User-space does whatever it wants with the returned buffer, and then
calls the kernel again, with a buffer and a checkpoint that was
returned by the kernel from previous SEND ioctl().
# Kernel re-arms itself to the specified checkpoint, and fills the
specified buffer with commands, attaches a new checkpoint and so on.
# Eventually kernel signals to the user that there are no more
commands.

Thanks,
