From 8a0934f2969df4cdea81cf48fde4c8626b32325d Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Mon, 7 Nov 2005 01:00:49 -0800 Subject: [PATCH] vesafb: Disable mtrr as the default vesafb occassionally gets the size wrong when setting the mtrr. When X or DRI attempts to set the mtrr, it will fail due to range overlap significantly affecting their performance. Disable mtrr and let the user explicitly enable it with the mtrr:n option.
