Hi all,
I have got this kernel with mmc driver on cubieboard2 from : https://github.com/jwrdegoede/linux-sunxi.git (test branch) .
I have made the Xen's Dom0 configuration according this :http://wiki.xenproject.org/wiki/Mainline_Linux_Kernel_Configs. and the kernel can be booted by Xen4.4.
The question we met is that some CMD can be accepted(CMD7,CMD0 ....) and but some can't(CMD52,CMD5,CMD51).
We have found that the CMD51 is attempted to read the data from SD card to memory through DMA , so we replaced all the dma_ops with xen_dma_ops , where it is in struct "dma_map_ops xen_swiotlb_dma_ops" in arch/arm/xen/mm.c.
Below is my kernel dump information, thanks everyone.
