USB 3 port file copy leads to kernel Panic with Processor SDK

dpa
Expert 1010 points
Other Parts Discussed in Thread: 66AK2E05

Hi,

I am continuing to port from MCSDK to Processor SDK Environment on our custom board with 66AK2E05 and I have a new Problem with USB.

After installing default Image for k2e-evm and NAND u-boot, I started Linux and all seems to be fine but when I insert a USB stick and try to copy the file from it to the board, it is leading to a kernel panic:

[   97.013444] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.
[   97.013444] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.
[   97.021528] xhci-hcd xhci-hcd.0.auto: Assuming host is dying, halting host.
[   97.047856] Unable to handle kernel paging request at virtual address bdde9000

Here is the whole log:

On the same hardware but with kernel from MCSDK, it is working without any problem. With MCSDK, I changed device tree to enable the second usb controller USB1 but USB was already working before change. I did not have the possibility with Processor SDK yet since I cannot copy the new device tree with USB stick. I will try to copy with ethernet link.

Has this Change something to do with this issue? Is it a kernel issue?

    Hi Dpa,

    I've forwarded this to the USB experts. Their feedback should be posted here.

    Are there any news on this topic?
    I cannot find any solution and I am kind of blocked.

    I have tried:
    - Other mass storage USB devices without success
    - I have tried one Link Power Management related bug fix without success
    - By enabling Debug entries for USB mass storage through menuconfig, I did not better clues on what is going on. No additional error, no additional warning, just kernel panic.

    EDIT: I tried today the kernel from MCSDK (zImage and k2e-evm.dtb) and I did not have any crash. So it is clear a kernel or device configuration issue.

    Do you have any clue what it can be?

    I compared the logs at Startup and lsusb output between kernel from MCSDk and kernel from Processor SDK and the only difference I saw is the way LPM is handled.

    MCSDK:

    Something to mention here: we have no LPM on our custom board. All Power Management Pins from our USB3.0 TI 8041 hubs are left floating (as explained in the datasheet of these hubs).
    Our Problem seems to be related to this but I cannot find how to avoid this. I tried disabling powermanagement in kernel via menuconfig but it does not make any difference.

    Have you any clue?

    New tests on my side:

    - I tried newest kernel provided with newest Processor SDK 03.01.00.06 and it does not make any difference. It still crashes after copying data from a mass storage USB stick. For your Information, I installed the default Image with program_evm tool.

    - I tried exactly the same thing but instead of our custom board on the EVMK2E Evaluation module v1.0.2.1 and it has the same problem.  The only difference is that there is no kernel panic but the error is the same (xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command) and it disconnects the usb device.

    - I tried a usb webcam from logitech and a stream with the following command:

    v4l2-ctl --stream-mmap=3 --stream-to=/home/root/test.mpeg

    The streaming is working fine and there is no disconnection or crashes on both platforms: custom board and EVM.

    I know there is an with evaluation board v1.0.2.1 and USB3: .

    with the solution provided here:

    But our custom board is not designed the same way and should not have this USB3 issue. Moreover the Webcam should not work properly then and it is not the case.

    I have no clue how I can go further her. Please, can you update on this Topic?

    Hi Dpa,


    Let focus first on the EVMK2E and processor SDK 3.01.00.06 to try to understand what is happening.

    If I understand correctly the below problem occur:
    When copying data from USB mass storage to K2E file system the below message occur:
          xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command
    and USB device disconnects.
    -Can you clarify what type of mass strorage device do you use?
    -Have you change the USB related portion of the kernel config or do you use the standard config?

    Hi Dpa,
    I've tried to boot the K2H EVM board with pre-built images of processor SDK and didn't see the UBS copy problem.
    The USB drivers are same for both K2H,K2L and K2E (Keystone USB3.0 drivers)
    How ever I will try the same with K2E board and update you.

    This issue is fixed, and it will be available in the coming Processor SDK release in December.

Subject: [PATCH] ARM: 8617/1: dma: fix dma_max_pfn()

Since commit 6ce0d2001692 ("ARM: dma: Use dma_pfn_offset for dma address translation"),
dma_to_pfn() already returns the PFN with the physical memory start offset
so we don't need to add it again.

This fixes USB mass storage lock-up problem on systems that can't do DMA
over the entire physical memory range (e.g.) Keystone 2 systems with 4GB RAM
can only do DMA over the first 2GB. [K2E-EVM].

What happens there is that without this patch SCSI layer sets a wrong
bounce buffer limit in scsi_calculate_bounce_limit() for the USB mass
storage device. dma_max_pfn() evaluates to 0x8fffff and bounce_limit
is set to 0x8fffff000 whereas maximum DMA'ble physical memory on Keystone 2
is 0x87fffffff. This results in non DMA'ble pages being given to the
USB controller and hence the lock-up.

NOTE: in the above case, USB-SCSI-device's dma_pfn_offset was showing as 0.
This should have really been 0x780000 as on K2e, LOWMEM_START is 0x80000000
and HIGHMEM_START is 0x800000000. DMA zone is 2GB so dma_max_pfn should be
0x87ffff. The incorrect dma_pfn_offset for the USB storage device is because
USB devices are not correctly inheriting the dma_pfn_offset from the
USB host controller. This will be fixed by a separate patch.

Subject: [PATCH] HACK: usb: dwc3: host: inherit dma configuration from parent
 dev

Now not all DMA paremters configured properly for "xhci-hcd" platform
device which is created manually. For example: dma_pfn_offset, dam_ops
and iommu configuration will not corresponds "dwc3" devices
configuration. As result, this will cause problems like wrong DMA
addresses translation on platforms with LPAE enabled like Keystone 2.

When platform is using DT boot mode the DMA configuration will be
parsed and applied from DT, so, to fix this issue, reuse
of_dma_configure() API and retrieve DMA configuartion for "xhci-hcd"
from DWC3 device node.

This patch is marked as a HACK since it was not accepted in its
current form upstream and an alternate solution is not clear yet.

Subject: [PATCH] usb: core: setup dma_pfn_offset for USB devices and,
 interfaces

If dma_pfn_offset is not inherited correctly from the host controller,
it might result in sub-optimal configuration as bounce
buffer limit might be set to less than optimal level.

Consider the mass storage device case.
USB storage driver creates a scsi host for the mass storage interface in
drivers/usb/storage/usb.c
The scsi host parent device is nothing but the the USB interface device.
Now, __scsi_init_queue() calls scsi_calculate_bounce_limit() to find out
and set the block layer bounce limit.
scsi_calculate_bounce_limit() uses dma_max_pfn(host_dev) to get the
bounce_limit. host_dev is nothing but the device representing the
mass storage interface.
If that device doesn't have the right dma_pfn_offset, then dma_max_pfn()
is messed up and the bounce buffer limit is wrong.

e.g. On Keystone 2 systems, dma_max_pfn() is 0x87FFFF and dma_mask_pfn
is 0xFFFFF. Consider a mass storage use case: Without this patch,
usb scsi host device (usb-storage) will get a dma_pfn_offset of 0 resulting
in a dma_max_pfn() of 0xFFFFF within the scsi layer
(scsi_calculate_bounce_limit()).
This will result in bounce buffers being unnecessarily used.

Hint: On 32-bit ARM platforms dma_max_pfn() = dma_mask_pfn + dma_pfn_offset

    Thanks Bin Liu,

    I tried the above 3 patches on EVMK2E board with the new kernel from Processor SDK 03.01.00.06 and it is still crashing.

    Here is the log of the bootup and the crash after pluging a USB3 mass storage device and copying one file from stick:

    Dpa,

    I must be missing other patches. I don't have a board to verify at the moment, could you please test the TI dev kernel git repo?

    git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git

    branch: ti-linux-4.4.y

    Hi Bin Liu,

    I compiled the kernel 4.4.34-02701-g988ab9c and it does not crash anymore. Thanks for your very valuable help.

    Side note: I needed to enable "open by fhandle syscalls" in General Setup by menuconfig before compiling. Otherwise it cannot completely boot up.

    Dpa,

    Thanks for the update. Glad the issue is solved.

    Yes, 'open by fhandle syscalls (CONFIG_FHANDLE)' is required for systemd.
