      t113-i mipi屏幕，longan系统屏幕的mapping->base为0是什么原因？具体是在哪里分配的呢，是不是需要在menuconfig里面打开某些配置？请大佬指教

      static int __iommu_map_sg(struct device *dev, struct scatterlist *sg, int nents,
		     enum dma_data_direction dir, unsigned long attrs,
		     bool is_coherent)
{
printk("[damon_mapping]{__iommu_map_sg} mapping->base 0x%px\n", dev->archdata.mapping->base);
	struct scatterlist *s = sg, *dma = sg, *start = sg;
	int i, count = 0;
	unsigned int offset = s->offset;
	unsigned int size = s->offset + s->length;
	unsigned int max = dma_get_max_seg_size(dev);

	for (i = 1; i < nents; i++) {
		s = sg_next(s);

		s->dma_address = DMA_MAPPING_ERROR;
		s->dma_length = 0;

		if (s->offset || (size & ~PAGE_MASK) || size + s->length > max) {
			if (__map_sg_chunk(dev, start, size, &dma->dma_address,
			    dir, attrs, is_coherent) < 0){
				goto bad_mapping;}

			dma->dma_address += offset;
			dma->dma_length = size - offset;

			size = offset = s->offset;
			start = s;
			dma = sg_next(dma);
			count += 1;
		}
		size += s->length;
	}
	if (__map_sg_chunk(dev, start, size, &dma->dma_address, dir, attrs,
		is_coherent) < 0){
		goto bad_mapping;}

	dma->dma_address += offset;
	dma->dma_length = size - offset;

	return count+1;

bad_mapping:
	for_each_sg(sg, s, count, i)
		__iommu_remove_mapping(dev, sg_dma_address(s), sg_dma_len(s));
	return 0;

        @vc915813805 这是哪一个驱动呢，是否有移植好初始化驱动

          @tronlong_support 初始化驱动是用tft08006改的，之前在d1_h上验证过这个初始化驱动应该是可行的，我打印也发现确实有进入到初始化驱动里面。
          现在大致猜测的问题是会不会是fb其实没有问题，因为lcd驱动其他地方出错导致lcd驱动提供给fb的起始地址就是0，然后fb这边也没有判断机制直接就用了，但具体问题可能出现在哪里还请大佬指教。🙏
