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

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

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.

Commit c952a8ba71 "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.

The USB Embedded High-speed Host Electrical Test (EHSET) defines the
SINGLE_STEP_SET_FEATURE test as follows:
1) The host enumerates the test device with VID:0x1A0A, PID:0x0108
2) The host sends the SETUP stage of a GetDescriptor(Device)
3) The device ACKs the request
4) The host issues SOFs for 15 seconds allowing the test operator to
raise the scope trigger just above the SOF voltage level
5) The host sends the IN packet
6) The device sends data in response, triggering the scope
7) The host sends an ACK in response to the data
This patch adds additional handling to the EHCI hub driver and allows
the EHSET driver to initiate this test mode by issuing a a SetFeature
request to the root hub with a Test Selector value of 0x06. From there
it mimics ehci_urb_enqueue() but separately submits QTDs for the
SETUP and DATA/STATUS stages in order to insert a delay in between.

Refactor so that register writes for configuration are only performed if
the device has a regmap provided and also register as a platform driver.
This allows the driver to be used to manage GPIO based control of the

If the connect signal is pulled high then the device will start up meaning
that if we just pull it high on probe then the device will start running
prior to the configuration being written out. Fix this by pulling the GPIO

An Embedded Host High-Speed Electrical Test (EHSET) test fixture is
used to initiate test modes on a host controller in order to perform
the high speed electrical testing procedure for USB-IF compliance.
When this test fixture is connected to a host, it can enumerate as
one of several selectable VID/PID pairs, each corresponding to one
of the following test modes:
* TEST_SE0_NAK
* TEST_J
* TEST_K
* TEST_PACKET
* HS_HOST_PORT_SUSPEND_RESUME
* SINGLE_STEP_GET_DEV_DESC
* SINGLE_STEP_SET_FEATURE

The current Makefile rules to build font support are messy and buggy.
Replace them by Kconfig rules:
- Introduce CONFIG_FONT_SUPPORT, which controls the building of all font
code,
- Select CONFIG_FONT_SUPPORT for all drivers that use fonts,
- Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16
font,
- Drop the bogus console dependency for CONFIG_VIDEO_VIVI,
- Always process drivers/video/console/Makefile, as some drivers need
fonts even if CONFIG_VT is not set.
This fixes (if CONFIG_SOLO6X10=y and there are no built-in console
drivers):
drivers/built-in.o: In function `solo_osd_print':
drivers/staging/media/solo6x10/solo6x10-enc.c:144: undefined reference to `.find_font'

The usb3503 driver sleeps a flat 100ms when resetting the chip, with a
comment about waiting for the reference clock. This seems to be a
board-specific detail that should not hold up boot across all platforms.
This patch reduces the sleep to the 4ms initialization delay that the
chip itself actually requires (as per its data sheet). If certain boards
require more time to set up the reference clock, they should change this
through local patches or add a proper, configurable synchronization
mechanism.

The usbtest driver includes some rather simple-minded logic for
selecting an altsetting to test. It doesn't work well for the g_zero
gadget, because it selects altsetting 0 (which doesn't have
isochronous endpoints) rather than altsetting 1 (which does have them,
if the gadget's hardware supports them). This prevents usbtest's
isochronous tests (15, 16, 22, and 23) from working with g_zero.
Since g_zero is one of the most common gadget drivers used for USB
testing, usbtest should do a better job of supporting it. But since
some programs may rely on the current scheme for selecting
altsettings, I didn't want to change it.
Instead, this patch (as1655) adds a module parameter to usbtest, which
can be used to override the default altsetting. Since usbtest is
never used by normal users (most distributions probably don't even
build it), the new module parameter won't inconvenience anybody. In
any case, it is entirely optional -- leaving it unset preserves the
existing behavior.
The patch also fixes a related bug in usbtest: After selecting an
altsetting, the driver neglects to store its selection.
