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.

Do I understand correctly that you have solved the issue by doing this?
If so then please could you send a patch. The process for submitting a
patch to Linux is described in Documentation/SubmittingPatches.
You should CC Stefano Stabellini since he is the maintainer of the Xen
bits in ARM Linux.
Many thanks,
Ian.

Can you give more input? (Xen log, ...) DOM0 has a 1:1 mapping layout,
so the swiotlb should not change anything.
With the 1:1 mapping, the driver can safely use DMA, can you try to see
which address is used by the DMA request?

Using swiotlb everywhere is just too slow. That's why Stefano took an
hybrid approach (1:1 mapping + bouncing for foreign pages).

Are you sure this branch is functional?
I strongly recommend that you stick to the well known trees referenced
from
http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Allwinner
If you want to use some other tree then the onus is on you to ensure
that it is functional on baremetal before running it under Xen.

Does the SD card work when the kernel is booted baremetal/natively
without Xen?

Hi there,
The kernel works without XEN (We have tested it yesterday.), but it failed when works with xen hypervisor.
We have done some research about the MMC driver.
If the command has nothing to do with the data transmission, it will work, such as CMD7 and CMD0
But when there is read or write operation( such as CMD52), the DMA module of the MMC controller will be used for the data transmission, instead of the DMA module of the CPU.
Our question is, should the XEN DMA memory map operations supported by swiotlib also work for the DMA module of MMC controller?
Thank you very much.
Best regards.

As Julien has explained the 1:1 mapping, which is enabled by default for
dom0 since Xen 4.4 should mean that the swiotlb is not necessary for
dom0 access to the MMC.
The swiotlb is there to handle the case where the address which dom0
sees is not the real hardware address, but the 1:1 mapping ensures that
they are the same.
Looking at your logs I don't see anything of the debug from
sunxi_mmc_irq, if you have enabled debug prints from this driver then I
would expect you should see something. This is certainly something worth
investigating.
There is probably a pretty strong correlation between commands which use
DMA and commands which need an IRQ to complete.
Ian.

That is correct: for normal dom0 DMA operations, we just rely on the
dom0 1:1 mapping (guest physical addresses == machine addresses).
We use the swiotlb-xen only to bounce DMA requests that involve foreign
pages: pages belonging to other guests but mapped in dom0 do not belong
to the 1:1 mapping, hence they need the swiotlb.
So if you are just doing DMA in Dom0 and you haven't even started a
second guest yet, you shouldn't need the swiotlb-xen.

Where did you replace the dma_ops with xen_dma_ops? Could you please
send out a patch so that I can understand what you modified exactly?
Keep in mind that for Dom0, get_dma_ops should already return
xen_dma_ops (see arch/arm/include/asm/dma-mapping.h:get_dma_ops), so in
theory you should already be getting the xen_dma_ops without having to
do anything.
So maybe the MMC driver is calling the arm_dma_ops functions directly
without going through get_dma_ops? It seems unlikely to me.
Can you point me to the right MMC driver in Linux that you are using?

I don't know what tree duqi is using but the main sunxi tree is
git://github.com/linux-sunxi/linux-sunxi.git
and the mmc stuff is in the sunxi-devel (the bleeding edge) branch.
The sunxi-next branch targets the next merge window and I don't think it
has mmc stuff in it yet.
The driver is in drivers/mmc/host/sunxi_mmc.c.

It looks all right to me. Nothing strange going on there.

Hi, I use the tree from: https://github.com/jwrdegoede/linux-sunxi.git and sunxi-test branch
The MMC driver is in driver/mmc/host/sunxi_mci.c
duqi .

I have added some debug information about the dma address and related register .
Could you give me some advice?
Many thanks.

Could you give me some advice?
Many thanks.

Hi, I use the tree from: https://github.com/jwrdegoede/linux-sunxi.git and sunxi-test branch
The MMC driver is in driver/mmc/host/sunxi_mci.c
Thank you very much.

Can you explain me why you are using an old development branch of Xen
4.4 rather than the release version?
Your build doesn't support correctly sunxi, please update at least to
Xen 4.4.
Next time you send an email on Xen devel, can you directly precise the
version of Xen you are using? It will avoid 5 mail round-trip for nothing.
Regards,

I cannot spot anything obviously wrong there either.
