From 137436c9a6ee385c883db09e41af763888ee7642 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Thu, 25 Apr 2013 19:20:59 +0000 Subject: powerpc/powernv: Patch MSI EOI handler on P8 The EOI handler of MSI/MSI-X interrupts for P8 (PHB3) need additional steps to handle the P/Q bits in IVE before EOIing the corresponding interrupt. The patch changes the EOI handler to cover that. we have individual IRQ chip in each PHB instance. During the MSI IRQ setup time, the IRQ chip is copied over from the original one for that IRQ, and the EOI handler is patched with the one that will handle the P/Q bits (As Ben suggested).
