From 25c063004a6d0048c4dece74db4da117b9ae623e Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Thu, 29 Mar 2012 19:11:27 -0700 Subject: [PATCH] drm/i915: open code gen6+ ring irqs We can now open-code the get/put irq functions as they were just abstracting single register definitions. It would be nice to merge this in with the IRQ handling code... but that is too much work for me at present. In addition I could probably collapse this in to a lot of the Ironlake stuff, but I don't think it's worth the potential regressions. This patch itself should not effect functionality.
