The POSIX_MAX_FDS option does not correspond to any standard POSIX option. It was used to define the size of the file descriptor table, which is by no means exclusively used by POSIX (also net, fs, ...). POSIX_MAX_FDS is being deprecated in order to ensure that Zephyr's POSIX Kconfig variables correspond to those defined in the specification, as of IEEE 1003.1-2017. Namely, POSIX_OPEN_MAX. CONFIG_POSIX_MAX_OPEN_FILES is being deprecated for the same reason. To mitigate any possible layering violations, that option is not user selectable. It tracks the newly added CONFIG_ZVFS_OPEN_MAX option, which is native to Zephyr. With this deprecation, we introduce the following Kconfig options that map directly to standard POSIX Option Groups by simply removing "CONFIG_": * CONFIG_POSIX_DEVICE_IO Similarly, with this deprecation, we introduce the following Kconfig options that map directly to standard POSIX Options by simply removing "CONFIG": * CONFIG_POSIX_OPEN_MAX In order to maintain parity with the current feature set, we introduce the following Kconfig options. * CONFIG_POSIX_DEVICE_IO_ALIAS_CLOSE * CONFIG_POSIX_DEVICE_IO_ALIAS_OPEN * CONFIG_POSIX_DEVICE_IO_ALIAS_READ * CONFIG_POSIX_DEVICE_IO_ALIAS_WRITE Gate open(), close(), read(), and write() via the CONFIG_POSIX_DEVICE_IO Kconfig option and move implementations into device_io.c, to be conformant with the spec. Lastly, stage function names for upcoming ZVFS work, to be completed as part of the LTSv3 Roadmap (e.g. zvfs_open(), ..). Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com> |

.. zephyr:code-sample:: zperf :name: zperf: Network Traffic Generator :relevant-api: net_config Use the zperf shell utility to evaluate network bandwidth. Description *********** The zperf sample demonstrates the :ref:`zperf shell utility <zperf>`, which allows to evaluate network bandwidth. Features ********* - Compatible with iPerf_2.0.5. Note that in newer iPerf versions, an error message like this is printed and the server reported statistics are missing. .. code-block:: console LAST PACKET NOT RECEIVED!!! - Client or server mode allowed without need to modify the source code. Supported Boards **************** zperf is board-agnostic. However, to run the zperf sample application, the target platform must provide a network interface supported by Zephyr. This sample application has been tested on the following platforms: - Freedom Board (FRDM K64F) - QEMU x86 - Arm FVP BaseR AEMv8-R - ARM BASE RevC AEMv8A Fixed Virtual Platforms Requirements ************ - iPerf 2.0.5 installed on the host machine - Supported board Depending on the network technology chosen, extra steps may be required to setup the network environment. Usage ***** See :ref:`zperf library documentation <zperf>` for more information about the library usage.
