From 4743484718e1d710321f24f8ef7d0124a48291b3 Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Mon, 12 Dec 2005 22:17:16 -0800 Subject: [PATCH] fbcon: Add ability to save/restore graphics state Add hooks to save and restore the graphics state. These hooks are called in fbcon_blank() when entering/leaving KD_GRAPHICS mode. This is needed by savagefb at least so it can cooperate with savage_dri and by cyblafb. State save/restoration can be full or partial.
