[rtl] Shared memory

[Peter Williamson <peterw@waybeat.com.au>]

Anyone got any hints on how I can get shared memory to wrk on a 486sx
with 8megs of mem. I have tried:-

2k shared mem - rt_process loads but user space mmap fails.
4k shared mem - rt_process seg faults but user space mmap appers to work
(i.e no errorss reported)

I think it has got something to do with the size of the nmem I am trying
to share.

Yes I have read the "Using Shared Memory in RT-Linux" doco lots and
lots.

rt fifos work fine.

Thanks
Peter
