    The USB PHY member of the HCD structure is renamed to 'usb_phy' and
    modifications are done in all drivers accessing it.
    This is in preparation to adding the generic PHY support.

  • 457a0955e   usbtest: Add interrupt EP testcases ... Browse Code »

    Two simple test cases for interrupt endpoints are added to the usbtest.c file.
    These are simple non-queued interrupt IN and interrupt OUT transfers. Currently,
    only gadget zero is capable of executing the interrupt EP test cases. However,
    extending the same to other gadgets is extremely simple and can be done
    on-demand.

    The two new tests added are
    - Test 25: To verify Interrupt OUT transfer
    - Test 26: To verify Interrupt IN transfer

    Since the default value of wMaxPacketSize is set as 1024, so interrupt
    IN transfers must be specified with the size parameter = multiple of
    1024. Otherwise the default value (512) in the usbtest application fails
    the transfer. See [RUN 4] for sample logs

    The application logs (usbtest) and corresponding kernel logs are as
    following:

    [Run 1]
    ./testusb -a -c 10 -s 2048 -t 26 -v 511
    usbtest 7-1:3.0: TEST 26: read 2048 bytes 10 times

    [Run 2]
    ./testusb -a -c 10 -s 1024 -t 25 -v 511
    usbtest 7-1:3.0: TEST 25: write 1024 bytes 10 times

    [Run 3]
    ./testusb -a -c 10 -s 1098 -t 25 -v 511
    usbtest 7-1:3.0: TEST 25: write 1098 bytes 10 times

    [Run 4 - Failure case scenario]
    ./testusb -a -t 26
    unknown speed /dev/bus/usb/007/004 0
    /dev/bus/usb/007/004 test 26 --> 75 (Value too large for defined data type)

    usbtest 7-1:3.0: TEST 26: read 512 bytes 1000 times
    usb 7-1: test26 failed, iterations left 999, status -75 (not 0)

  • ce21bfe60   USB: Add LVS Test device driver ... Browse Code »
    2

    OTG3 and EH Compliance Plan 1.0 talks about Super Speed OTG Verification
    system (SS-OVS) which consists of an excersizer and analyzer.

    USB Compliance Suite from Lecroy or Ellisys can act as such SS-OVS for
    Link Layer Validation (LVS).

    Some modifications are needed for an embedded Linux USB host to pass all
    these tests. Most of these tests require just Link to be in U0. They do
    not work with default Linux USB stack since, default stack does port
    reset and then starts sending setup packet, which is not expected by
    Link Layer Validation (LVS) device of Lecroy Compliance Suit. Then,
    There are many Link Layer Tests which need host to generate specific
    traffic.

    This patch supports specific traffic generation cases. As of now all the
    host Lecroy Link Layer-USBIF tests (except TD7.26) passes
    with this patch for single run using Lecroy USB Compliance Suite
    Version 1.98 Build 239 and Lecroy USB Protocol Analyzer version 4.80
    Build 1603. Therefore patch seems to be a good candidate for inclusion.
    Further modification can be done on top of it.

    lvstest driver will not bind to any device by default. It can bind
    manually to a super speed USB host controller root hub. Therefore, regular
    hub driver must be unbound before this driver is bound. For example, if
    2-0:1.0 is the xhci root hub, then execute following to unbind hub driver.

    echo 2-0:1.0 > /sys/bus/usb/drivers/hub/unbind

    Then write Linux Foundation's vendor ID which is used by root hubs and
    SS root hub's device ID into new_id file. Writing IDs into new_id file
    will also bind the lvs driver with any available SS root hub interfaces.

    echo "1D6B 3" > /sys/bus/usb/drivers/lvs/new_id

    Now connect LVS device with root hub port.

    Test case specific traffic can be generated as follows whenever needed:

    1. To issue "Get Device descriptor" command for TD.7.06:
    echo > /sys/bus/usb/devices/2-0\:1.0/get_dev_desc

    2. To set U1 timeout to 127 for TD.7.18
    echo 127 > /sys/bus/usb/devices/2-0\:1.0/u1_timeout

    3. To set U2 timeout to 0 for TD.7.18
    echo 0 > /sys/bus/usb/devices/2-0\:1.0/u2_timeout

    4. To issue "Hot Reset" for TD.7.29
    echo > /sys/bus/usb/devices/2-0\:1.0/hot_reset

    5. To issue "U3 Entry" for TD.7.35
    echo > /sys/bus/usb/devices/2-0\:1.0/u3_entry

    6. To issue "U3 Exit" for TD.7.36
    echo > /sys/bus/usb/devices/2-0\:1.0/u3_exit

  • 32b36eeae   USB: usbtest: add a timeout for scatter-gather tests ... Browse Code »
    5

    In usbtest, tests 5 - 8 use the scatter-gather library in usbcore
    without any sort of timeout. If there's a problem in the gadget or
    host controller being tested, the test can hang.

    This patch adds a 10-second timeout to the tests, so that they will
    fail gracefully with an ETIMEDOUT error instead of hanging.

    TEST 11 unlinks the URB read request for N times. When host and gadget
    both initialize pattern 1 (mod 63) data series to do IN transfer, the

    xhci: Cleanups, non-urgent fixes for 3.14.

    Happy Holidays, Greg!

    Here's four patches to be queued to usb-next for 3.14.

    One adds a module parameter to the xHCI driver to allow users to enable
    xHCI quirks without recompiling their kernel, which you've already said
    is fine. The second patch is a bug fix for new usbtest code that's only
    in usb-next. The third patch is simple cleanup.

    The last patch is a non-urgent bug fix for xHCI platform devices. The
    bug has been in the code since 3.9. You've been asking me to hold off
    on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and
    be backported to stable once 3.14 is out.

    These have all been tested over the past week. I did run across one
    oops, but it turned out to be a bug in 3.12, and therefore not related
    to any of these patches.

    Please queue these for usb-next and 3.14.

    Thanks,
    Sarah Sharp

    Commit c952a8ba7136505cd1ca01735cc748ddc08c7d2f "usb: usbtest: add a
    test case to support bos for queue control" will cause USB 2.01 and USB
    2.10 devices with a BOS descriptor to fail case 15 of the control test.

    The Link PM errata (released in 2007, updated in 2011) says:

    "The value of the bcdUSB field in the standard USB 2.0 Device Descriptor
    is used to indicate that the device supports the request to read the BOS
    Descriptor (i.e. GetDescriptor(BOS)). Devices that support the BOS
    descriptor must have a bcdUSB value of 0201H or larger."

    The current code says that non-SuperSpeed devices *must* return -EPIPE,
    as this comment shows:

    /* sign of this variable means:
    * -: tested code must return this (negative) error code
    * +: tested code may return this (negative too) error code
    */
    int expected = 0;

    This means the test will fail with USB 2.01 and USB 2.10 devices that
    provide a BOS descriptor. Change it to only require a stall response if
    the USB device bcdUSB is less than 2.01.
