Subject: [9fans] Hooking up to a timer in a driver
Date: Mon, 21 Jun 1999 13:51:16 -0400

Hey all,


I have been hunting through the kernel code to try and figure out how to 
setup a timer in a file system driver I am writing.

Here is my problem :

I am currently outputting data to a device via my own file system (MIDI). I 
need a way to have a timer go off in the file system every n Milliseconds, 
and check my output queue to see if it is time to send the data. Currently 
I am doing this by spawning a kproc in the driver, and having it sleep for 
n milliseconds, wake up, check the queue the sleep. Thought this seems to 
work, it does not seem like the cleanest way to do this.

I would like to wire up a handler to a timer mechanism that the OS supports 
so I could just have the OS call my function every n ticks.

I have not been able to find such a thing by searching the source code.

Any Clues ?


Thanks!
