I was working on the ufsj stuff as a Google SoC project with Scott. It is very close to beta, however this past week involved school starting back up, so I have been unable to do any work at all. However, now that I am settled in at school (for some definition of settled in), I have time to devote to ufsj again. I hope to release a beta real soon now, so stay tuned. Hey Brian! Thanks for the info - I've been very interested in the development of the project, but Scott is too busy doing other real stuff, and I oddly didn't even think to ask you anything. :( I'm willing to play with pre-beta patches or tarballs/etc. Feel free to contact me off list if you'd like a guinea pig.

On Sat, Sep 10, 2005 at 09:34:48PM +0200, Zlatan Ibrahimovic wrote: Hi folks, I've seen clock software interrupt thread (referring to clk_ithd in kern/kern_intr.c); watching to manpages I read that priority is used as vector for that thread. My question is how can I call this software handler? There's no track in the IDT for the associated handler... (ia32, for better check see i386/i386/exception.s). The softclock() function is registered as an another one handler for SWI_CLOCK by calling the swi_add() function. Since clk_ithd is NULL at the moment when swi_add() for softclock() handler is called, interrupt thread is created for SWI_CLOCK in swi_addr() by the ithread_create() function. An interrupt thread is a special kthread and interrupt threads run ithread_loop() function as the main function for kthread. Interrupt handler for the softclock() function is returned in softclock_ih. The simplified idea of ithread_loop() is the following: if there is the request for some handler, then process this request by requested handler else voluntary switch context. Another one handler for SWI_CLOCK is siopoll(). If you run ps auxw | grep clock you will see two handlers for swi5 (SWI_CLOCK). When hardclock() decides that softclock() should be called is schedules clk_ithd ithread via handler softclock_ih by calling swi_sched(). ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
