[rtl] "Driver for comunications card"
Hello all
I'm developing a rt-driver for a comunication card (interrupt drivers,
frames
transmition etc) , first i was develop the driver on rtlinux-0.6-2.0.33,
i have some
problems like:
- when the comunication card have a lot of traffic sometimes i got this
message
kmalloc called nonatmoically from int fa03
gfp called nonatmoically from int fa03
What's the meanning of this message.
- what happen if i try to write on a full rt-fifo?
- Sometimes the machine hang with a oops message, where could i find
information
( URL ) for debug this problem.
- I try to pass my driver on rtlinux-0.6-2.0.33 to rtlinux-1.1-2.0.36
but
my rtfifo's appear with strange information... what's the version that i
could
update my driver without many problems.
- My aplication have a lot of tasks ( i need to control comunications
RS-232
300 bps with 240 microcontrolers at time) do you think that rt-linux
isn't a
good option?
Thanks a lot
