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.
