From 9a5f019b1a9ea6a75ba36d7c312ff069006ed479 Mon Sep 17 00:00:00 2001 From: Eric Hustvedt Date: Tue, 20 Jun 2006 14:36:41 -0400 Subject: [PATCH] intelfb: add vsync interrupt support [02/05] intelfb: Add interrupt related register definitions Add constants for accessing HWSTAM, IER, IIR, and IMR registers. Add constants for interrupt types supported by the 8xx and 9xx chipsets. The registers are also stored in the hwstate struct and dumped in the debug routine.
