Hello,
there is a problem in ali_agp.c (both, -CURRENT and -STABLE): If I
boot the generic kernel, it panics in agp_ali.c, when it tries to
allocate memory for the gatt. Some simlpe tests showed, that the
initial aperture size is reported as zero by the device:
static int
agp_ali_attach(device_t dev)
{
struct agp_ali_softc *sc =3D device_get_softc(dev);
struct agp_gatt *gatt;
int error;
=20
error =3D agp_generic_attach(dev);
if (error)
return error;
=20
sc->initial_aperture =3D AGP_GET_APERTURE(dev);
This is zero---------------------^^^^^^
=20
for (;;) {
gatt =3D agp_alloc_gatt(dev);
if (gatt)
break;
=20
/*
* Probably contigmalloc failure. Try reducing the
* aperture so that the gatt size reduces.
*/
if (AGP_SET_APERTURE(dev, AGP_GET_APERTURE(dev) / 2)) {
agp_generic_detach(dev);
return ENOMEM;
}
}
sc->gatt =3D gatt;
=20
/* Install the gatt. */
Since I don't have a machine ready running -CURRENT, I can't really
debug this. How can I disable agp0 on boot time?
