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?

    Hi dsd,

    We have an engineer working on verifying the proposed solution as we speak

    For dma-buf blobs, based on conversations I've had internally, it would seem the exact same mechanism we are currently verifying can be used (in absence of the proper extension), just replacing a ump handle with a dma-buf one.
