From 58221097a8d8aa2151a70cbf749977998bb3d815 Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Mon, 26 Jun 2006 00:26:31 -0700 Subject: [PATCH] [PATCH] atyfb: Remove unneeded calls to wait_for_idle The drawing functions of atyfb is unecessary syncing the GPU which is affecting performance. Remove the calls, any direct access by fbcon to the framebuffer will always be preceeded by a call to atyfb_sync().
