From 97de7e658664865f042b1729f3f959ee0fb7b6a4 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 19 Jan 2017 15:05:41 +0100 Subject: [PATCH] st/mesa: ask pipe driver to recreate derived internal resources when (re-)binding external textures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use the resource_changed callback to invalidate internal resources derived from external textures when they are (re-)bound. This is needed to comply with the requirement from the GL_OES_EGL_image_external extension that a call to glBindTexture guarantees that all further sampling will return values that correspond to the values in the external texture at or after the time that glBindTexture was called.
