From 4f70d83089bb1fea3cda9aa050e5bbd7f3768734 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Bruno=20Jim=C3=A9nez?= Date: Wed, 11 Jun 2014 17:28:01 +0200 Subject: [PATCH] r600g/compute: solve a bug introduced by 2e01b8b440c1402c88a2755d89f40292e1f36ce5 That commit made possible that the items could be one just after the other when their size was a multiple of ITEM_ALIGNMENT. But compute_memory_prealloc_chunk still looked to leave a gap between items. Resulting in that we got an infinite loop when trying to add an item which would left no space between itself and the next item. Fixes piglit test: cl-custom-r600-create-release-buffer-bug And the test for alignment I have just sent: http://lists.freedesktop.org/archives/piglit/2014-June/011135.html Sorry about this.
