From: Nanley Chery Date: Fri, 21 Aug 2015 01:00:20 +0000 (-0700) Subject: Revert "mesa/formats: refactor by collapsing cases in switch statement by type" X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=29e953b07b8c1e4d27f53c4a1430154a3d67f896;p=mesa.git Revert "mesa/formats: refactor by collapsing cases in switch statement by type" This reverts commit ffe6c6ad5f719dedd1b6b95e8590e3f20b23d340. _mesa_format_num_components() does not include the padding bits in mesa formats containing 'X' channels. This could cause mipmap generation for certain uncompressed formats to underestimate the number of channels in the source image by 1.
