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,

    I've been working on this at our end.  With DMA_BUF, I can confirm that without the EGL_LINUX_DMA_BUF_EXT you need DRI3 to be able to create an xPixmap from which an eglImage can be generated, but this isn't currently available on the platform.  EGL_LINUX_DMA_BUF_EXT is, however, going to be present in the next driver release.

    I'm still actively looking into the possibility of using UMP for a similar purpose and will get back to you when I know anything more.  In the meantime, please let me know if there's anything else.

    Thanks,

    Rich
