Travis Geiselbrecht	d06fbd35c8	[arch][vax] redid the exception code, added timers ... The port more or less fully works now, except for actual interrupt driven io and proper atomics. Also hit a floating point exception in the string benchmark.	2019-10-21 02:52:38 -07:00
Travis Geiselbrecht	23ebd514c1	[platform][vax] first working context switch ... Timers aren't firing yet so the system locks up as soon as any timeout is involved. Enough to run the command line for a bit.	2019-10-20 22:04:20 -07:00
Travis Geiselbrecht	89705cb065	[arch][vax] initial stab at booting on a vax ... Booting on a real MicroVAX 3100/40 via netboot and on simh emulating a micrvax 3900. Doesn't fully work, lots of stuff is stubbed out, but it starts to run and hits unimplemented bits and stops.	2019-10-12 21:54:04 -07:00
