Subject: [9fans] sdiahci.c on sources broken?
Date: Thu, 25 Sep 2008 21:58:22 +0200	[thread overview]
Message-ID: <9889b044e939e4884b56a67475e09e81@gmx.de> (raw)

this is from eriks contrib:

static void
westerndigitalhung(Drive *d)
{
	if((d->portm.feat&Datapi) == 0 && d->active &&
	    TK2MS(Ticks-d->intick) > 5000){
		dprint("%s: drive hung; resetting [%lux] ci=%lux\n",
			d->unit->name, d->port->task, d->port->ci);
		d->state = Dreset;
	}
}

and this is the version on sources:

static void
westerndigitalhung(Drive *d)
{
	if((d->portm.feat&Datapi) == 0 && d->active && TK2MS(d->intick) > 5000){
		dprint("%s: drive hung; resetting [%lux] ci %lx\n",
			d->unit->name, d->port->task, d->port->ci);
		d->state = Dreset;
	}
}

if i understand it right, d->intick is just the point in time it started some
io request. it does:

p->intick = MACHP(0)->ticks;
p->active++;

so it seems the version on sources is wrong, and eriks version does the right thing.
(calculating the time the operation takes (current time - time of request start))

can somebody confirm this?
