Benjamin Walsh 2b429de7f3 test_fifo: test timeout APIs Test the nano_xxx_fifo_wait_timeout() APIs. First, the task waits with a timeout and times out. Then it wait with a timeout, but gets the data in time. Then, multiple timeout tests are done for the fibers, to test the ordering of queueing/dequeueing when timeout occurs, first on one fifo, then on multiple fifos. Finally, multiple fibers pend on one fifo, and they all get the data in time, except the last one: this tests that the timeout is recomputed correctly when timeouts are aborted. NOTE: The timeout APIs test is contained within its own file so that it is easily reusable by a microkernel test that verifies that nano timeouts and microkernel timers can coexist.

Title: test_fifo

Description:

This test verifies that the nanokernel FIFO APIs operate as expected.

---------------------------------------------------------------------------

Building and Running Project:

This nanokernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make qemu

---------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

---------------------------------------------------------------------------
