[Mesa-dev] [PATCH v4 0/7] etnaviv: update derived texture resources of (re)imported buffers

[Christian Gmeiner]

Hi all.

I am looking for some r-b/s-b for the core bits - anyone?

> to get weston / wayland_egl working on etnaviv, we need to update the texture
> resources derived from imported buffers every time they are re-imported.
>
> This patchset is based on the github-etnaviv/for_mainline_v1 branch and adds
> a new pipe_screen::resource_changed callback that is called inside
> dri2_from_planar and instructs the pipe driver to invalidate the internal
> (texture) resources that are derived from the re-imported resource.
>
> I've also added an updated version of the earlier GL_OES_EGL_image_external
> patches that now use resource_changed to invalidate internal derived resources
> when an external texture is (re-)bound, to comply with the specification.
>
> The etnaviv implementation of resource_changed just sets the texture seqno
> to the resource seqno - 1. The initial seqno of imported resources is set to 1
> so that texture resources created from them are actually older and trigger the
> resolve on first use.
>
> Changes since v3:
>  - Added resource_changed to ddebug, rbug, and trace wrapper drivers
