tools: usb: ffs-aio-example: Fix build error with aarch64-*-gnu-gcc toolchain(s)

2022-11-09T11:37:56+00:00

The tools/usb/aio_simple.c file when cross-compiled with aarch64-*-gnu-gcc toolchain(s) leads to the following errors: aio_simple.c:30:10: fatal error: endian.h: No such file or directory 30 | #include | ^~~~~~~~~~ aio_simple.c:88:14: note: (near initialization for 'descriptors.fs_count') aio_simple.c:110:14: error: initializer element is not constant 110 | .hs_count = htole32(3), | ^~~~~~~ aio_simple.c:110:14: note: (near initialization for 'descriptors.hs_count') aio_simple.c:124:22: error: initializer element is not constant 124 | .wMaxPacketSize = htole16(512), | ^~~~~~~ aio_simple.c:124:22: note: (near initialization for 'descriptors.hs_descs.bulk_sink.wMaxPacketSize') Fix these compilation issues by: - Switching to _DEFAULT_SOURCE: _BSD_SOURCE is deprecated and gives a build warning. Let's use _DEFAULT_SOURCE instead. - Currently this file uses library htole16/32 function calls. Replace these with equivalent 'cpu_to_le16/32' calls.

treewide: Add SPDX license identifier - Makefile/Kconfig

2019-05-21T08:50:46+00:00

Add SPDX license identifiers to all Make/Kconfig files which: - Have no license information of any form These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

tools: ffs-aio-example: use endpoint addresses from descriptors

2015-01-15T15:41:49+00:00

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 USB device. Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

tools: ffs-aio-example: add missing wMaxPacketSize for HS descs

2015-01-12T18:13:29+00:00

It's needed, to have more than 64 bytes of maxpacketsize. Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

tools: ffs-aio-example: add license information

2014-06-30T17:53:36+00:00

Add missing information about license. Some people will probably want to reuse this code in their projects released under variety of licenses. For this reason this example is under Public Domain license to avoid GPL limitations. Acked-by: Michal Nazarewicz Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

tools: ffs-aio-example: convert to new descriptor format

2014-06-30T17:53:32+00:00

Since commit [ac8dde11: “Add flags to descriptors block”] functionfs supports a new descriptor format, so we update example application to make it using recomended version of descriptors. Acked-by: Michal Nazarewicz Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

tools: ffs-aio-example: fix header values endianess

2014-06-30T17:53:27+00:00

We wrap numeric values of fs_count and hs_count fields in htole32, because they should be in little-endian format. Acked-by: Michal Nazarewicz Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

tools: usb: aio example applications

2014-05-14T14:23:24+00:00

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
