Keywords: Realtime kernel interrupts Message-ID: <366@shell.shell.com> Date: 11 Jul 88 17:18:29 GMT References: <10450@udenva.cair.du.edu> <8411@pur-ee.UUCP> <797@taux01.UUCP> Sender: usenet@shell.com Reply-To: stan@shell.UUCP (Stan Hanks) Organization: Shell Development Company, Bellaire Research Center, Houston TX Lines: 23 Just a quick question, while we're talking about realtime OS: what is the nominal interrupt dispatch time for Unix (time from the the hardware interrupt line being yanked until your interrupt handler is executing)? If you post some info on this, please include * the type of hardware you are using * the which version of Unix you are using * how you determined the time involved Thanks. If you mail direct to me, I'll summarize to comp.os.misc. Please post follow-ups to comp.os.misc. Stan Hanks Research Computer Scientist, (and Postmaster!)
