From 844f8268e1cde496a854a72e080558f3c5700583 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Tue, 4 Oct 2016 23:29:27 +0200 Subject: gallium/radeon/winsyses: set reasonable max_alloc_size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit which is returned for GL_MAX_TEXTURE_BUFFER_SIZE. It doesn't have any other use at the moment. Bigger allocations are not rejected. This fixes GL45-CTS.texture_buffer.texture_buffer_max_size on Bonaire.
