[Asterisk-Dev] Hard real-time?

[Ricardo Poppi]

Hi all! There are some linux kernel projecs that provides hardware 
real-time kernel for real time applications. I´ve been looking around 
about RTLinux and RTAI. Those hard real-time kernel implementations 
provides a hardware abstraction layer where the regular linux kernel is 
executed as a low priority task. But - now comes the candy - all the 
real time applications are executed by this HAL as high priority so it 
should guarantee the real time responses needed.

But - now comes the issue - the "real-time application" needs to be 
written using those "new" cappabilities. Take a short look at this 
sentence about RTLinux programing impact: "...From the application 
programmers point of view, the queues look very much like standard UNIX 
character devices, accessed via POSIX read/write/open/ioctl system 
calls. Shared memory is currently accessed via the POSIX mmap calls..."

Do anybody knows about a hard real-time asterisk dev 
project/prototype/beta going on?

Thanks in advance,
