Hi Dmitry,
some news from the testing front: It works fairly well - and it doesn't
crash =:). We set up a quite demanding test scenario which consists of
two Sick Laser scanners feeding two UART ports at 500 Kbit/s. The UARTs
are on a special PC104 card, sharing the same edge-triggered IRQ line.

Hi,
I got the following errors when my .config contained
a CONFIG_PPC601_SYNC_FIX=y

Hi Jan, I started the tests and had problems on unloading the module.
I am probably doing something wrong but I think the driver shouldn't crash.
Probably it is missing some sanity checks on rtdm_munmap like
if (! (user_info && user_info->mm))
return -EXXX;
I'll investigate the problems
Hi Jan, it just happened once and I couldn't reproduce (I didn't want to
reproduce it too since I would need to restart my computer because the driver
wouldn't unload)...
When it happened I forgot to start the timer running the latency program and
my driver failed to load and due to some mistak

Hi all,
this is a first attempt to add the requested mmap functionality to the
RTDM driver API. Anyone interested in this feature is invited to test my
patch (Rodrigo... ;) ). Comments on the implementation are welcome as well.
Philippe, I need xnarch_remap_page_range for this and added a #define

... and this version is even more useful than the previous one (now with
EXPORT_SYMBOL!). Be warned: I just compiled it, I count on third-party
testers.
