scw 5cabdd3709 Some snippets of documentation for mvme68k... 2000-12-14 20:30:14 +00:00
jdolecek ca57e681bd g/c obsolete vtrace(2) stuff 2000-12-13 18:13:05 +00:00
scw 5d5ebb1b73 Simplify the reboot code: 
Always jump through the PROM's reset vector, regardless of board type.
  Fix a stack offset problem in the mvme147 reset code path.

scw 8ace7abc75 A small splx()/spl0()/soft interrupt related optimisation. If we're 
dropping to spl0, use inline code to check if a soft interrupt is
pending instead of taking the hit of a function call to do the check.
 2000-12-10 18:43:02 +00:00
scw c5b6f43634 Define `splzs()' to be `splserial()' instead of `spl4()', which was 
wrong anyway since it blindly set SPL to 4 regardless of the prevailing
level.
