From: Mathias Fröhlich Date: Mon, 19 Oct 2009 16:50:41 +0000 (-0400) Subject: drm/radeon/kms: fix cs parser tex bit 11 check X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ceb776bc87280eb8d13f38e4d7afae757e95af44;p=linux-beck.git drm/radeon/kms: fix cs parser tex bit 11 check The problem boils down to the order when the bit11 of the texture size is or'ed to the original width. In the end each mipmap level has the same width or height because of that 11 bit is ored to the scaled down lod with and thus blows up the size again to the full size or more due to the power of two rounding afterwards. The attached patch changes this order so that the texture sizes are computed correct. Also the on error the yet missing inputs to the size computation are printed which helped me to find out where it really breaks.
