      @veye_xumm 编译错误 我把信息发给您看一下,是驱动里面的结构体
      CC drivers/media/i2c/veyecam2m.o

          参见代码的注释,你的内核缺少这个接口,需要注掉这个函数。

                      正常来说,你只要在这个文件的基础上做如下修改:

                                  @veye_xumm 现在遇到个新的问题,我不知道是板子硬件支持,我是用DMABUF 作为V4L2的qbuf, 但是返回错误 Failed to queue buffer: Invalid argument,您看一下我这部分代码,是不是该驱动支持,
                                  //将缓冲区注册到摄像头
                                  struct v4l2_buffer buf={0};
                                  struct v4l2_plane planes[1]={0};
                                  buf.index =0;
                                  buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
                                  buf.memory = V4L2_MEMORY_DMABUF;
                                  buf.length = 1;
                                  buf.m.planes = planes;
                                  planes[0].m.fd = frame_buffers[i].dmabuf_fd;
                                  planes[0].length =buffer_size;

                                      if (ioctl(cam_fd, VIDIOC_QBUF, &buf) < 0) {
                                          perror("Failed to queue buffer");
                                          return -1;
                                      }

                                      @veye_xumm 我看了 那个源码 内存采用 普通的内存,我希望的是用 drm 或dmaheap 的,这样可以实现零copy

                                        @flaty 我的理解中,相机驱动并不涉及到BUFF模式的限制。实际上数据的收取和防止到内存是rk的mipi接收单元的驱动所决定的。
                                        下面是网上插到的信息,希望能有帮助。

                                        从你贴的代码来看,报错 Failed to queue buffer: Invalid argument(EINVAL)通常意味着结构体成员设置有问题,或者驱动不支持 DMABUF 模式。结合你写的代码,我帮你逐条排查一下:


                                        1. v4l2_buffer 初始化问题

                                        你这里写的是:

                                        struct v4l2_buffer buf={0};
                                        struct v4l2_plane planes[1]={0};
                                        

                                        这是对的,但要注意 buf.length 必须和 planes 数组元素数量一致,并且 buf.m.planes 不能为空。


                                        2. buf 关键字段设置

                                        你代码里:

                                        buf.index = 0;
                                        buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
                                        buf.memory = V4L2_MEMORY_DMABUF;
                                        buf.length = 1;
                                        buf.m.planes = planes;
                                        
                                        • ✅ buf.type 用 V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE 是对的(说明驱动是 multiplanar 类型)。
                                        • ✅ buf.memory 设置成 DMABUF 正确。
                                        • ❌ buf.index 不是 0 就行,它必须是你在 VIDIOC_REQBUFS 时分配的 buffer 数量里的一个合法索引。比如如果你 req.count = 4,那么只能用 0..3。

                                        3. plane 字段设置

                                        planes[0].m.fd = frame_buffers[i].dmabuf_fd;
                                        planes[0].length = buffer_size;
                                        

                                        问题可能出在这里:

                                        • planes[0].m.fd:必须是 dma-buf 的有效 fd。
                                        • planes[0].length:应该是该 plane 的大小,但 通常驱动并不依赖这个值。有些驱动要求设置 bytesused,即:
                                        planes[0].bytesused = buffer_size;
                                        

                                        如果 bytesused 没设,驱动可能直接返回 EINVAL。


                                        4. 建议的正确写法

                                        试着改成这样:

                                        struct v4l2_buffer buf;
                                        struct v4l2_plane planes[VIDEO_MAX_PLANES];  // 通常 >= 1
                                        memset(&buf, 0, sizeof(buf));
                                        memset(planes, 0, sizeof(planes));
                                        
                                        buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
                                        buf.memory = V4L2_MEMORY_DMABUF;
                                        buf.index = i;                   // 循环里的 buffer 索引
                                        buf.length = 1;                  // plane 数量
                                        buf.m.planes = planes;
                                        
                                        planes[0].m.fd = frame_buffers[i].dmabuf_fd;
                                        planes[0].length = buffer_size;   // plane 总大小
                                        planes[0].bytesused = buffer_size; // 必须加上
                                        

                                        5. 确认驱动是否支持 DMABUF

                                        不是所有 V4L2 驱动都支持 V4L2_MEMORY_DMABUF。你可以用下面的方法确认:

                                        v4l2-ctl -d /dev/video0 --querycap
                                        

                                        如果 ioctl 里不支持 DMABUF,就算代码写对了也会 EINVAL。
                                        有些驱动只支持 MMAP,那就得用 V4L2_MEMORY_MMAP。


                                        👉 建议:先在 QBUF 前打印出 buf 和 planes[0] 的值,确认 index、fd、bytesused 都合理。

                                          修改了代码:

                                              for(int i = 0; i < req_buffer.count; ++i)
                                              {
                                                  struct v4l2_buffer buf;
                                                  struct v4l2_plane planes[num_planes];
                                                  memset(&buf, 0, sizeof(struct v4l2_buffer));
                                                  memset(&planes, 0, sizeof(planes));
                                          
                                                  buf.index = i;
                                                  buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
                                                  buf.memory = V4L2_MEMORY_DMABUF;
                                                  buf.m.planes = planes;
                                                  buf.length = 1;
                                                  buf.bytesused = fmt.fmt.pix.sizeimage;
                                                  buf.m.planes[0].m.fd = dmabuf_fds[i];
                                                  planes[0].bytesused = fmt.fmt.pix.sizeimage;
                                                  planes[0].m.fd = dmabuf_fds[i];
                                                  planes[0].length = fmt.fmt.pix.sizeimage;
                                                  printf("index: %d\n bytesused: %d  fd: %d length: %d\n",
                                                         buf.index,planes[0].bytesused,planes[0].m.fd ,planes[0].length );
                                                  if (0 != ioctl(cam_dev_fd, VIDIOC_QBUF, &buf))
                                                  {
                                                      perror("Unable to queue buffer");
                                                      return -1;
                                                  }
                                              }
                                          

                                          我打印了信息,如下:
                                          dam申请内存是没问题的
                                          alloc dma_heap buffer. fd: 5, raw_buf: 0x7f7df08000, size: 3110400
                                          alloc dma_heap buffer. fd: 6, raw_buf: 0x7f7dc10000, size: 3110400
                                          alloc dma_heap buffer. fd: 7, raw_buf: 0x7f7d918000, size: 3110400
                                          qbuf第一个缓冲区就报错
                                          index: 0
                                          bytesused: 3110400 fd: 5 length: 3110400
                                          Unable to queue buffer: Invalid argument
                                          我用了3个缓冲,DMA_AALLOC都正确,目前看似乎是这个相机驱动不支持DMA-BUF的模式,您看呢

                                            DMA BUFF模式的支持,并不是相机驱动所决定的,而是rockchip的rkcif这个驱动决定的。 数据的传递顺序是:camera-->mipi rx--->rkcif。

                                            我查阅了一些资料,显示5.10版本的rk3588的驱动好像是比较明确不支持DMA BUFF模式的。这也就限制了你camera到其他外设驱动的buffer零拷贝传递的能力。 不过如果你只是想零拷贝从camera驱动中拿到数据,进入算法的话,V4L2_MEMORY_MMAP模式应该就可以支持。

                                            rkcif驱动在kernel6以上版本是否支持了DMA buffer模式,没有确切的说法。
