X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=97de7e658664865f042b1729f3f959ee0fb7b6a4;p=mesa.git st/mesa: ask pipe driver to recreate derived internal resources when (re-)binding external textures 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.
