I would like to answer round about 15000
questions here. All of them looking like this:
( I use the word LinuX for the non RT part)
I use ((any LinuX function)) from within my
RT process and get ((any smptom)). Help me!!.
Please fill in the symptom and the LinuX function you like :-).
Many Linux function call sti/cli or so to do atomic things.
Any call to LinuX from within a RtLinuX call break this!!!
Example:
LinuxCall{
cli();
do( not )disturb;
sti();
}
If this gets called from LinuX it can be interrupted between
cli/sti by any RTprocess. So if the RTprocess calls this
again the atomic call is broken. So I put this on my
"Things not to do" list and I'm fine with RTlinuX.
