From 2356614b08bf8769790c4f1f55c83d95f802bc51 Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Mon, 26 Jun 2006 00:26:23 -0700 Subject: [PATCH] [PATCH] savagefb: Allocate space for current and saved register states Allocate space for 2 register states: 'current' for the current state of the hardware, and 'saved', to be used for restoring the hardware to a sane state. This is in preparation for the addition of state save and restore hooks to make savagefb work together with the latest Xorg savage driver.
