I did, it seems to look for device at 0,0:
static int i915_get_bridge_dev(struct drm_device *dev)
{
struct drm_i915_private *dev_priv = dev->dev_private;
dev_priv->bridge_dev = pci_get_bus_and_slot(0, PCI_DEVFN(0, 0));
if (!dev_priv->bridge_dev) {
DRM_ERROR("bridge device not found\n");
return -1;
}
return 0;
}
are you sure this is the ISA bridge device? these patches put it at 1f.
