RSS Bot Posted November 4, 2023 Share Posted November 4, 2023 Description Add patches as Justin Green mentioned to enable DMA buffer caching on hantro and rkvdec driver. Hantro and rkvdec driver have set dst_vq->dma_attrs to DMA_ATTR_ALLOC_SINGLE_PAGES | DMA_ATTR_NO_KERNEL_MAPPING and it will not pass check in dma_alloc_noncontiguous, so I add a patch to deal with it.
