From e6d1cc31fa7a7252c07933a7e311fb0d8b331e12 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 30 Jun 2017 14:08:49 -0700 Subject: [PATCH] svga: fix texture buffer object regression With change 8aba778fa2cd98a0b5a7429d3c5057778a0c808c we stopped binding sampler objects for texture buffers. That broke our texture sample / sampler view setup code. Now, we loop over the max(num samplers, num sampler views) and handle the sampler and view information separately. For texture buffers, the sampler will be NULL but the sampler view non-null.
