ne2000_asic_ioport_write:
if (s->dcfg & 0x01) {
/* 16 bit access */
+ assert(s->rcnt >= 2);
+ assert(s->rsar + 2 <= s->stop);
ne2000_mem_writew(s, s->rsar, val);
s->rsar += 2;
s->rcnt -= 2;
}
First assert triggered with:
s->dcfg: 0x49
s->rcnt: 1
s->rsar: 0x4156
s->stop: 0xc000
What surprises me the most is that it's coming from an outb, not outw. Is
this really correct, or is the ne2000 emulation perhaps missing a
differentiation between 16- and 8-bit I/O?
I'll add *readb/writeb locally, to see if things go better, and report
findings/patch.
