tools: ffs-test: fix header values endianess

2014-06-30T18:23:58Z

It appears that no one ever run ffs-test on a big-endian machine, since it used cpu-endianess for fs_count and hs_count fields which should be in little-endian format. Fix by wrapping the numbers in cpu_to_le32. Cc: stable@vger.kernel.org Signed-off-by: Michal Nazarewicz Signed-off-by: Felipe Balbi

tools: ffs-test: convert to new descriptor format fixing compilation error

2014-06-19T13:51:35Z

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).

tools: usb: aio example applications

2014-05-14T14:23:24Z

This patch adds two example applications showing usage of Asynchronous I/O API of FunctionFS. First one (aio_simple) is simple example of bidirectional data transfer. Second one (aio_multibuff) shows multi-buffer data transfer, which 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. Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

usb: tools: fix a regression issue that gcc can't link to pthread

2013-12-04T23:10:54Z

Reproduce: ray@hr-bak:~/usb$ make -C tools/usb/ make: Entering directory `/home/ray/usb/tools/usb' gcc -Wall -Wextra -g -lpthread -I../include -o testusb testusb.c /tmp/cc0EMxfy.o: In function `main': /home/ray/usb/tools/usb/testusb.c:508: undefined reference to `pthread_create' /home/ray/usb/tools/usb/testusb.c:531: undefined reference to `pthread_join' collect2: error: ld returned 1 exit status make: *** [testusb] Error 1 make: Leaving directory `/home/ray/usb/tools/usb' 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. Signed-off-by: Huang Rui Signed-off-by: Greg Kroah-Hartman

testusb: remove all mentions of 'usbfs'

2013-02-08T20:15:24Z

Commit 8a424bf40d772fedacc91862ecc86f10541fabb3 (tools/usb: remove last USBFS user) removed 'usbfs' files from the source but retained mentions of 'usbfs' all over the place, most importantly in the misleading error messages printed in case USB device files are not there. Remove all the mentions of 'usbfs' for good now! Signed-off-by: Sergei Shtylyov Signed-off-by: Greg Kroah-Hartman

tools/usb: remove unneeded 'continue' and simplify condition

2013-01-12T00:03:37Z

Basically remove unneeded code. Since that 'continue' is at the end of the for() there's no need for it. Signed-off-by: Sasha Levin Acked-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

tools/usb: remove last USBFS user

2012-09-10T18:10:37Z

In commit fb28d58b ("USB: remove CONFIG_USB_DEVICEFS") USBFS got removed. Since it is gone we can stop using it in testusb and try udev nodes right away. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Greg Kroah-Hartman

testusb: expose looping forever option "l" to user

2012-06-13T23:15:03Z

The testusb.c tool has support for looping forever implemented, which may be useful for stress test, yet it is not exposed to the user, so even though the code is there, it cannot be used. This commit adds "l" to the set of options handled by the application which enables the feature. Also, I collate help information for each command line option to make it easier to use for novice.
