From 0790d5e148c0747499742a3c09ba5f1c07f9ed0d Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 30 Jul 2008 12:28:47 -0700 Subject: [PATCH] i915: remove settable use_mi_batchbuffer_start The driver can know what hardware requires MI_BATCH_BUFFER vs MI_BATCH_BUFFER_START; there's no reason to let user mode configure this.
