RGA使用问题

板子是rk 3568，在https://github.com/airockchip/librga 下载了librga以及参考了sample中rag_copy_demo.cpp，实现了以下代码：

1. rga_buffer_t g_src_img;
   
2. rga_buffer_t g_dst_img;
   
3. rga_buffer_handle_t g_src_handle;
   
4. rga_buffer_handle_t g_dst_handle;
   
5. 
   
6. g_src_handle = 0;
   
7. g_dst_handle = 0;
   
8. memset(&g_src_img, 0, sizeof(g_src_img));
   
9. memset(&g_dst_img, 0, sizeof(g_dst_img));
   
10. memset(g_dst_buf, 0x80, width*height*3);
    
11.   
    
12. g_src_handle = importbuffer_virtualaddr((char*)mpp_buffer_get_ptr(buffer),  width*height*3);
    
13. g_dst_handle = importbuffer_virtualaddr(g_dst_buf,  width*height*3);
    
14. if (g_src_handle == 0 || g_dst_handle == 0)
    
15. {
    
16.       printf("importbuffer failed!\n");
    
17.       return ;
    
18. }
    
19. 
    
20. g_src_img = wrapbuffer_handle(g_src_handle, width, height, RK_FORMAT_RGB_888);
    
21. g_dst_img = wrapbuffer_handle(g_dst_handle, width, height, RK_FORMAT_RGB_888);
    
22. 
    
23. IM_STATUS checkRet = imcheck(g_src_img, g_dst_img, {}, {});
    
24. if (IM_STATUS_NOERROR != checkRet)
    
25. {
    
26.       printf("%d, check error! %s", __LINE__, imStrError((IM_STATUS)checkRet));
    
27.       return;
    
28. }
    
29. 
    
30. printf("dest handle:%d handle:%d fd:%d vir:%x phy:%x\n", g_dst_handle, g_dst_img.handle, g_dst_img.fd, g_dst_img.vir_addr, g_dst_img.phy_addr);
    
31. printf("src handle:%d handle:%d fd:%d vir:%x phy:%x\n", g_src_handle, g_src_img.handle, g_src_img.fd, g_src_img.vir_addr, g_src_img.phy_addr);
    
32. IM_STATUS retStatus = imcopy(g_src_img, g_dst_img);
    
33. if (retStatus == IM_STATUS_SUCCESS)
    
34. {
    
35.            printf("imcopy running success!\n");
    
36. }
    
37. else
    
38. {
    
39.            printf("imcopy running failed, %s\n", imStrError((IM_STATUS)retStatus));
    
40. }
    
41. 
    
42. //这里对g_dst_buf进行操作，写文件之类
    
43. //......
    
44. 
    
45. if (g_src_handle)
    
46.             releasebuffer_handle(g_src_handle);
    
47. if (g_dst_handle)
    
48.             releasebuffer_handle(g_dst_handle);

复制代码其中，printf打印的g_dst_handle、g_src_handle均为-1，fd，vir__addr, phy_addr这些值均为0，看着是不正常的。请问流程哪里出错了，或者还需要安装其他什么库？


其中，初始化的日志出现

1. librga fail to get driver version! Compatibility mode will be enabled.
   
2. 
   
3. 334 im2d_rga_impl rga_version_below_minimun_range_user_driver(304): The driver may be compatible, but it is best to update the driver to version 1.2.4. You can try to update the SDK or update the <SDK>/kernel/drivers/video/rockchip/rga3 directory individually. current version: librga 1.9.1, driver .
   
4. rga_api version 1.9.1_[4]
