From 6c43e0016e344de3d7e82b098992cdfecbff2ab2 Mon Sep 17 00:00:00 2001 From: Julien Isorce Date: Thu, 2 Jun 2016 15:03:01 +0100 Subject: st/va: it is valid to release the VABuffer of an exported resource MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit pipe_resource_reference(&res, NULL) will decrement reference counting, i.e. p_atomic_dec(res->count). But the va surface still has the initial reference since it has created the resource. So calling vaDestroyImage on a derived image calls VaDestroyBuffer but the decrementation won't reach 0. It is just wrong for vlVaDestroyBuffer to rely on the export_refcount flag. Finally the vaapi intel driver has the same logic.
