From a4952f60895d5d8bd1e03c3f9b204a83c363ae81 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 26 Mar 2012 19:13:18 +0100 Subject: [PATCH] video/console: Clip the right margin clear to the visible region For some unknown reason, yres_virtual was 2x larger the the size specified by i915 and so when blit_clear_margins() tried to clear the full virtual right-hand margin it tried to write far beyond the end of the buffer. This limits the clear to only the visible portion of the right-hand margin, similar to how the bottom margin is treated.
