[B2-devel] Basilisk II updates

[Gwenole B. <gb....@fr...>]

Hi,

I have recently updated the Basilisk II CVS with:

1) Much improved responsiveness on NetBSD systems.

Since the time slice is not small enough there, I opted for an hybrid=20
m68k instruction counter (countdown) vs. periodic time check. The=20
countdown is recalibrated every 10 ticks and kicks in at around 1000=20
Hz. When the counter is below zero, a normal check is performed to see=20=

if a Mac timeslice (16 ms) expired and thus triggering interrupts.=20
Performance is not fully on par with a system supporting small=20
quantums, but mouse and operations are now much smoother under=20
NetBSD/i386.

Next commits will adapt the code for SDL video and fix the extra=20
ethernet interrupt trigger with has to be called only if there is no=20
pthreads at all (ether_dummy.cpp used).

2) You now can use Basilisk II with JIT on Darwin 8.0.1 for x86, thus=20
very likely permitting it to run in next MacOS incarnations. ;-)

Bye,
