[PATCH v3 0/6] etnaviv: update derived texture resources of (re)imported buffers

[Philipp Zabel]

Hi,

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 v2:
 - Added resource_changed paragraph to screen.rst

regards
Philipp
