From 0fa50a1990fcdfca6a9f75a68f8e4ed22ddd6949 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Thu, 21 Jun 2012 22:19:48 +0200 Subject: MPTAPLE: generate from devicetree.cb This patch adds support for autogenerating the MPTABLE from devicetree.cb. This is done by a write_smp_table() declared weak in mpspec.c. If the mainboard doesn't provide it's own function, this generic implementation is called. Syntax in devicetree.cb: ioapic_irq The ioapic_irq directive can be used in pci and pci_domain devices. If there's no directive, the autogen code traverses the tree back to the pci_domain and stops at the first device which such a directive, and use that information to generate the entry according to PCI IRQ routing rules.
