Thanks for the infos, I'll try kernel thread or timer/softirq in the next
days.
I'll let you know which of them fit my problems.
I actually have about +/- 1msec of freedom (but still require more
investigation).

What are your timing requirements? How much over/

Not accurate at all. New code should use kthread_create,

Hi folks,
I'm developing a custom SPI driver (char device) on a MPC5200b, the
microcontroller linked as slave implements a protocol that must follow
strict timing constraints. I need to receive and send messages every 6msec.
Actually there is a user space program that synchronizes the two units, bu
