From fb702b942bf638baa6cbbbda9f76794db62921ef Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Fri, 25 Jun 2010 16:41:11 -0400 Subject: arch/tile: Enable more sophisticated IRQ model for 32-bit chips. This model is based on the on-chip interrupt model used by the TILE-Gx next-generation hardware, and interacts much more cleanly with the Linux generic IRQ layer. The change includes modifications to the Tilera hypervisor, which are reflected in the hypervisor headers in arch/tile/include/arch/.
