61 | [ifdef] INTX-MESSAGES? | |
62 | ||
63 | \ Officially, this "pcie" southbridge device does not support intx. | |
64 | \ Unofficially, it seems to work for now, so the platform team has | |
65 | \ requested we turn this functionality on until the real solution | |
66 | \ (sideband interrupts through the fpga over the ssi bus) is implemented. | |
67 | ||
68 | \ The pcie to pci bridge at the root of the southbridge nexus has a | |
69 | \ zero valued, read only 'interrupt-pin' register. Because of this, | |
70 | \ the common OBP probing code does not create an 'interrupts' property, | |
71 | \ and Solaris does not enable INTx. Therefore, we have to do it here. | |
