Andreas Kling	79ffdb7205	A lot of hacking: ... - More work on funneling console output through Console. - init() now breaks off into a separate task ASAP. - ..this leaves the "colonel" task as a simple hlt idle loop. - Mask all IRQs on startup (except IRQ2 for slave passthru) - Fix underallocation bug in Task::allocateRegion(). - Remember how many times each Task has been scheduled. The panel and scheduling banner are disabled until I get things working nicely in the (brave) new Console world.	2018-10-22 11:15:16 +02:00
Andreas Kling	46ff281695	Turn the syscall interrupt into a trap (by switching the gate type.) ... This leaves interrupts enabled while we're in the kernel, which is precisely what we want. This uncovered a horrendous problem with kernel tasks silently overflowing their stacks. For now I've simply increased the stack size but I need a more MMU-y solution for this eventually.	2018-10-19 11:31:18 +02:00
Andreas Kling	56c1f9db8e	A userspace process can now GPF and the OS goes on! ... This is really rickety, but it kinda sorta works for my test GPF!	2018-10-17 23:49:32 +02:00
Andreas Kling	72bb80a9ae	These changes were lying around uncommitted in the old repo. ... I'm just gonna commit them without too much thinking and then take it from there.	2018-10-16 11:06:35 +02:00
Andreas Kling	9396108034	Import the "gerbert" kernel I worked on earlier this year. ... It's a lot crappier than I remembered it. It's gonna need a lot of work.	2018-10-16 11:02:00 +02:00
