Hi,
I was wondering if there is already a method in the fusion native
skin to turn the main thread of a process into real-time. Did not
find anything. I guess it would be easy to add such feature to
librtai based on existing syscalls. Should I write a patch?
Something like "rt_task_attach"?
Actually, you can already do this by calling the internal POSIX API
extension: pthread_init_rt(), which is part of the system skin
implicitely attached to a user-space RT app.
Then what about some redefinition for the native skin? Just to have
the API streamlined.
In fact, it can't be a call to pthread_init_rt() as I first suggested,
because the RTAI skin maintains some information locally for each of its
tasks which would not be properly set up by the latter call. So a
wrapper to this call won't do it either. Anyway, crafting the proper
call for the RTAI API should not be a complex issue.
It's called rt_task_shadow() in the CVS head. Documented, tested and
working here. HTH.
