And it works. Got stuck for a moment before realizing that the writeback target framebuffer from the vc4 drm interface cannot be simply plugged into the rp1's plane FB_ID. I of course needed to create a dedicated framebuffer allocated on the rp1's card, while sharing the underlying dma buf. But now it works quite well.
