[B2-devel] ticks problem fixed (thanks!)

[Brian J. <bjj...@us...>]

Thanks for fixing the problem with Ticks getting incremented on every
interrupt, instead of just the 60Hz interrupt.  Games are much more
playable now.  8-)

There's only one more Irix-specific issue I know of in BasiliskII:
BII does not set the pthread scope explicitly, instead it defaults to
system scope on Linux (indeed, that's the only scope available in
LinuxThreads), but to process scope on Irix.  That means the Irix
pthreads library does all the thread scheduling itself, instead of
letting threads always block in the kernel.  This is fine for many
apps, but in BasiliskII, the main instruction emulation thread doesn't
get preempted often enough to keep the video and audio running
smoothly...  The fix is to use system scope or, since that requires
root privileges on Irix (high-priority realtime pthreads can starve
out kernel threads, such as the network packet handlers), the
Irix-specific "bound scope".

Anyway, I hope to get a patch together in the next week or so.  If it
can get into BasiliskII 1.0, BII will simply rock on Irix.

Thanks,

						Brian J. Johnson
