From: Tapani Pälli Date: Thu, 12 Mar 2015 05:58:48 +0000 (+0200) Subject: mesa: mesa_bufferiv utility function for buffer objects X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=34df5ebd778fd3027db0f380eab71a95cfa298c0;p=mesa.git mesa: mesa_bufferiv utility function for buffer objects Patch adds new function 'mesa_bufferiv' and refactors existing GetActiveUniformBlockiv and GetActiveAtomicCounterBufferiv to use it. corresponding Piglit tests: arb_uniform_buffer_object* arb_shader_atomic_counters* (Many tests hit the corresponding queries.)
