The device driver has routines for servicing I/O requests. I understand that these routines run in the top part of the kernel stack. The routines have a nesting of 10-12 functions having 10-100 lines each. Could you tell us what is the minimum available run time memory in the per-process kernel stack for running these routines? We want to avoid problems during the integration testing:-) Regards Satya To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
