lima: support exporting dma_buf #5

Closed enunes closed 6 years ago

enunes commented 6 years ago

This enables lima to export a shared buffer from a dma_buf handle using the DRM prime infrastructure. With this, it is possible to export a gbm_bo allocated with lima to the display driver for rendering to a display.

This was tested on the Allwinner A20 with the sun4i-drm driver, along with lima.

Updated it to call drmPrimeHandleToFD first and return in case of error.
