Mali-400 drivers don't support import texture from DMA-BUF

MICHAL LAZO

I get this strength issues from ODROID

drivers for Mali-400 don't support

eglCreateImageKHR with EGL_LINUX_DMA_BUF_EXT

?

but drivers internaly use DMA_BUF

any reason or workaround for this for this?

And why UMP is supported and DMA_BUF isn't?

    Thanks a lot for checking, your answer is totally understandable. Glad to hear that EGL_LINUX_DMA_BUF_EXT is coming!

    In this new version, will EGL_LINUX_DMA_BUF_EXT be available when Mali is compiled to use UMP internally, e.g. as  VARIANT=mali400-r1p1-gles11-gles20-linux-monolithic-no_profiling-x11-ump-umplock ?

    Or will the dmabuf import functionality only be available for Mali setups where dmabuf is used internally? I would love to switch to that.
