usb: misc: usbtest: Remove timeval usage

2015-12-01T22:52:58Z

timeval is deprecated and not y2038 safe. Its size also changes according to 32 bit/ 64 bit compilation. Replace it with 32 and 64 bit versions of its individual fields, giving two ioctls with different code values. The two ioctls are necessary to maintain the 32 bit and 64 bit userspace compatibility with a 64/32 bit kernel. Change unsigned to __u32 types for a definitive userspace interface. This is in accordance with the psABI that the unsigned type is always 32 bits. Also use motonic timer instead of real time to ensure positive delta values. Refactor usbtest_ioctl for readability to isolate the handling of the testing timing measurement. The official testusb userspace tool can be changed in a separate patch to reflect the __u32 changes as well. It can use the usbtest_param_32 struct, since 32 bit seconds is long enough for test durations. Signed-off-by: Deepa Dinamani Reviewed-by: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

usb: misc: usbtest: improve the description for error message

Merge tag 'usb-for-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

Felipe writes: usb: patches for v4.4 merge window This pull request is large with a total of 136 non-merge commits. Because of its size, we will only describe the big things in broad terms. Many will be happy to know that dwc3 is now almost twice as fast after some profiling and speed improvements. Also in dwc3, John Youn from Synopsys added support for their new DWC USB3.1 IP Core and the HAPS platform which can be used to validate it. A series of patches from Robert Baldyga cleaned up uses of ep->driver_data as a flag for "claimed endpoint" in favor of the new ep->claimed flag. Sudip Mukherjee fixed a ton of really old problems on the amd5536udc driver. That should make a few people happy. Heikki Krogerus worked on converting dwc3 to the unified device property interface. Together with these, there's a ton of non-critical fixes, typos and stuff like that. Signed-off-by: Felipe Balbi

usb: misc: usbtest: add bulk queue test

2015-10-13T18:19:49Z

The bulk queue tests are used to show 'best performance' for bulk transfer, we are often asked this question by users. The implementation is the same with iso test, that is queue request at interrupt completion, so we reuse the iso structures, and rename them as common one. It's result should be very close to IC simulation, in order to get that, the device side should also need to prepare enough queue. We have got the 'best performance' (IN: 41MB, OUT: 39MB) at i.mx platform (USB2, ARM Cortex A9, stream mode need to enable) with below command: Host side: modprobe usbtest ./testusb -a -t 27 -g 64 -s 16384 ./testusb -a -t 28 -g 64 -s 16384 Gadget side: modprobe g_zero loopdefault=1 qlen=64 buflen=16384 Signed-off-by: Peter Chen Cc: Greg KH Cc: Alan Stern Signed-off-by: Felipe Balbi

usb: misc: usbtest: format the data pattern according to max packet size

2015-09-27T15:54:31Z

With this change, the host and gadget doesn't need to agree with transfer length for comparing the data, since they doesn't know each other's transfer size, but know max packet size.
