WebThen the buffer chunks might be merged, but this is done by the DMA-mapping code. For your case, without any call to DMA-mapping, you can only assume that the buffer is contiguous in physical memory if orig_nents is 1. I've changed the use of nents to orig_nents to make things consistent - this code operates only on the unmapped buffers. WebYou can create framebuffers with drmModeAddFB (3) and use it for mode-setting and scanout. To access the buffer, you first need to retrieve the offset of the buffer.
