John Baldwin	8088699f79	- Overhaul the software interrupt code to use interrupt threads for each ... type of software interrupt. Roughly, what used to be a bit in spending now maps to a swi thread. Each thread can have multiple handlers, just like a hardware interrupt thread. - Instead of using a bitmask of pending interrupts, we schedule the specific software interrupt thread to run, so spending, NSWI, and the shandlers array are no longer needed. We can now have an arbitrary number of software interrupt threads. When you register a software interrupt thread via sinthand_add(), you get back a struct intrhand that you pass to sched_swi() when you wish to schedule your swi thread to run. - Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit more intuitive. Also, prefix all the members of struct intrhand with 'ih_'. - Make swi_net() a MI function since there is now no point in it being MD. Submitted by: cp	2000-10-25 05:19:40 +00:00
Doug Rabson	ec502c357d	* Add rudimentary DDB support (no kgdb, no backtrace, no single step). ... * Track recent changes to SWI code. * Allocate RIDs for pmaps (untested). * Implement assembler version of cpu_switch - its cleaner that way.	2000-10-10 14:57:10 +00:00
Doug Rabson	1ebcad5720	This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will ... not work on any real hardware (or fully work on any simulator). Much more needs to happen before this is actually functional but its nice to see the FreeBSD copyright message appear in the ia64 simulator.	2000-09-29 13:46:07 +00:00
