Hi,
The short answer is .. not yet.
Victor has started this process with his posix_io module.
I may be wrong but this does not yet allow you to read from disk during
init_module.
During the realtime task you are also , on the surface , out of luck.
One way to do this would be to have a user agent task on the end of a
fifo.
The real time task could then ask the user agent task to read the disk
for you.
The user agent task would then give the data back to the realtime task
through another fifo.
Tricky to code and make fool proof.
This would also not be in "real time" since the user task in 2.2 kernels
can hold you up for several hundreds of millisecs.
The low latency patches may help 2.3 kernels are reportedly better.
regards
Phil Wilshire
