Use dmabuf instead of eglCreateWaylandBufferFromImageWL

[suhrid-s]

Hi,

Based on this MR to mesa,
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/29266
It looks like there were plans to use dmabuf instead of eglCreateWaylandBufferFromImageWL by default from
2.46 or latest by 2.48.

1. Since 2.46 is already out and I still see eglCreateWaylandBufferFromImageWL being used, does that
   mean it will be removed by 2.48?

2. Does this mean cog will handle wayland buffer creation similar to WebKit; i.e. use dmabuf by default
   and fall back to egl implementation or will the egl implementation be completely removed?

Also, is there a branch where the dmabuf implementation is under review/in progress?

Thanks!

@suhrid-s We are not currently working on adding support for DMA-BUF in Cog; instead we have added inside WebKit and can be used with the new WPEPlatform API—which Cog does not use for now.

Do you mean that in the future, cog can just use the WPEPlatform API and this problem will not happen again?

@aperezdc In fact, this problem is very serious, because Mali's official egl does not support the eglCreateWaylandBufferFromImageWL extension, so now cog cannot be run on Mali's GPU, especially on SOCs such as rockchip.
