From c24a8a7a99885d5b986f38f6631f69e7794a3e5e Mon Sep 17 00:00:00 2001 From: Jayachandran C Date: Sat, 21 Dec 2013 16:52:13 +0530 Subject: MIPS: Netlogic: Add MSI support for XLP Add MSI chip and MSIX chip definitions. For MSI, we map the link interrupt to a MSI link IRQ which will do a second level of dispatch based on the MSI status register. The MSI chip definitions use the MSI enable register to enable and disable the MSI irqs. For MSI-X, we split the 32 available MSI-X vectors across the four PCIe links (8 each). These PIC interrupts generate an IRQ per link which uses a second level dispatch as well. The MSI-X chip definition uses the standard functions to enable and disable interrupts.
