From: Roland Scheidegger Date: Mon, 12 Nov 2012 19:35:04 +0000 (+0100) Subject: gallivm,draw,llvmpipe: use base ptr + mip offsets instead of mip pointers X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=26097c4855b97ee6e362c19df11d51fb7fd42192;p=mesa.git gallivm,draw,llvmpipe: use base ptr + mip offsets instead of mip pointers This might have a slight overhead but handling mip offsets more like the width (and image) strides should make some things easier (mip level being just part of the offset calculation) later.
