Hello. My driver needs to wait for the hardware to complete something. I obviously want it to sleep (it is process context), and when the operation will finish it will wake up the sleeping context (the waking up will be in interrupt context). Should I use completion variables or wait queues sleeping ? Which is preferred / recommended ?
Aren't completion variables "one shot"? I mean once completion is signalled the job is done (You can't re-use)! Please CMIIW Regards, Rajat -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
