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			`/*`

Replace the hardcoding of 255 as the clock interrupt vector with CLOCK_VECTOR and define it as 254, not 255. Vector 255 is already in use as the AP wakeup vector on the HP rx2600. This needs to be made more dynamic. The likelyhood of vector 254 being in use is pretty small, but we already have code to assign vectors to IPIs (see sal.c) and it's preobably better to have a centralized "vector manager" that hands out vectors based on some imput (like priority). 2003-01-06 01:39:25 +00:00			`#define CLOCK_VECTOR 254`

Gah, spell extern correctly. Do not trust cut/paste via old mozilla builds. 2002-10-04 01:57:46 +00:00			`extern u_int64_t itc_frequency;`

Declare itc_frequency and itm_reload. 2002-10-04 01:23:58 +00:00
