969678c098 tools: ffs-aio-example: use endpoint addresses from descriptors
This makes examples more platform independent and more compatible with
USB standard, as endpoint addresses in given interface may differ
between hardware platforms or even between configurations in single

e7cf773d43 USB patches for 3.19-rc1
Here's the big set of USB and PHY patches for 3.19-rc1.
 
 The normal churn in the USB gadget area is in here, as well as xhci and
 other individual USB driver updates.  The PHY tree is also in here, as
 there were dependancies on the USB tree.
 
 All of these have been in linux-next.

b9a4274699 tools: ffs-test: add compatibility code for old kernels
If ffs-test is used with a kernel prior to 3.14, which do not
support the new descriptors format, it will fail when trying to
write the descriptors.  Add a function that converts the new
descriptors to the legacy ones and use it to retry writing the
descriptors using the legacy format.

Also add “-l” flag to ffs-test which will cause the tool to
never try the new format and instead immediatelly try the
legacy one.  This should be useful to test whether parsing
of the old format still works on given 3.14+ kernel.

Commit [ac8dde11: “usb: gadget: f_fs: Add flags to descriptors block”]
which introduced a new descriptor format for FunctionFS removed the
usb_functionfs_descs_head structure, which is still used by ffs-test.
tool.

Convert ffs-test by converting it to use the new header format.  For
testing kernels prior to 3.14 (when the new format was introduced) and
parsing of the legacy headers in the new kernels, provide a compilation
flag to make the tool use the old format.

Finally, include information as to when the legacy FunctionFS headers
format has been deprecated (which is also when the new one has been
introduced).

may to be used in high performance applications.

Both examples contains userspace applications for device and for host.
It needs libaio library on the device, and libusb library on host.

Comments:
In the latest version (4.7.3) of gcc compiler, it requres that
libraries must follow the object or source files like below:

"gcc hello.c -lpthread" instead of "gcc -lpthread hello.c"

And it isn't encountered at gcc version 4.7.2.
So this patch fix to move the pthread option after testusb.c.

The unaligned tests are called after their aligned
equivalents but for fewer iterations (since alignment
failure is generally immediate).

5bc9661cba USB: testusb: testusb compatibility with FunctionFS gadget
The FunctionFS gadget may provide the source/sink interface
not as the first interface (with id == 0) but some different
interface hence a code to find the interface number is
required.

(Note that you will still configure the gadget to report
idProduct == 0xa4a4 (an "echo 0xa4a4
>/sys/module/g_ffs/parameters/usb_product" should suffice) or
configure host to handle 0x0525:0xa4ac devices using the
usbtest driver.)

2201d6b162 USB: testusb: an USB testing application
The testusb program just issues ioctls to perform the tests
implemented by the kernel driver.  It can generate a variety
of transfer patterns; you should make sure to test both regular
streaming and mixes of  transfer sizes (including short transfers).

For more information on how this can be used and on USB testing
refer to <URL:http://www.linux-usb.org/usbtest/>.
