Changes for v2:
- Add le16_to_cpu to read descriptor value [Patch 5/7]
- Add MAX_SGLEN (128 currently) for maximum sglen [Patch 1/7]
- Using local variable to save max macket size value, in case
some compiler create more code for dereferences all the pointers
at every iteration. [Patch 5/7]
Hi all,
In this series, we do some improvements for usb test, including
usbtest at host side, sourcesink at gadget side, and testusb
app running at host side.
The main changes:
- Format the data pattern according to max packet size, then, the
host and gadget doesn't need to agree on the transfer size when
check data correctness.
- change the default value for length from 512 to 1024 at testusb app.
- Unlimit the length of sglen for iso transfer.
With these changes, now we can run the test (usbtest/g_zero) with
default parameters for all kinds of tests (interrupt transfer has not
tested due to lack of its support at g_zero).
For doing data compare test:
At host side:
modprobe usbtest alt=1 pattern
At gadget side:
modprobe g_zero pattern=1
Then run testapp at host side:
./testapp -a
