hi,
I'm actually engineer for one period of six month. On this period i
have to implement EDF scheduling in eCos.
first of all, i will try to implement cyg_thread_deadline_wait() with
one table who store the different deadline, and after this, this
function will set priority for each thread. i assume i have to call
the scheduler ( bitmap i think ) for launch the thread with the
earliset deadline. i don't know if i am in the good way...
can you give me some help please because i don't know the function
who call the scheduler : i assume if i attribuate the priority with
cyg_thread_set_priority in cyg_thread_deadline_wait function, i have
to call the scheduler for launch the thread with the new highest
priority.
if you could help i will be very pleased..
Best Regards,
Thank you
