Re: [SOLVED] Re: ARAnyM VMs with Debian hanging at 100% CPU usage
Since it does not appear to cause any real harm (presumaby nfeth still works
after the message?), I'd leave it.
Yes, it works either way. Interrupts are some black magic, and I
must admit I don't really understand the impact of the issue even
after reading the verbose commit message…
The issue was that nfeth uses an interrupt level that is below the
vertical blank interrupt (VBL) on Falcon.
The VBL interrupt is good for exactly nothing and so it used to be
disabled as soon as it was ever
encountered by its own interrupt handler (by setting the proper IPL).
The necessary logic wasn't properly ported to the new generic interrupt
handling scheme when the
Atari interrupt code was rewritten - the wrong interrupt level was set
by the VBL, effectively reenabling
the running nfeth interrupt (from memory, I had a closer look at that
when the patch was submitted).
Looks like I may have something working that will require a minimum of
changes to the ne.c driver -
I hear you - and I am still working on sanitizing the driver's
Oh, sounds like fun. Good luck! (ragnar76 is the one in need of
such drivers, he'd probably help testing, too.)
need to run a few last tests though.
