  • ea9936f32   spi: loopback-test: add elapsed time check ... Browse Code »

    This adds checks whether the elapsed time is longer than the minimam
    estimated time. The estimated time is calculated with the total
    transfer length per clock rate and optional spi_transfer.delay_usecs.

    In order to test various spi_messages including zero-length transfer,
    this adds zero length into the iterate_len list.

  • 8916671e9   spi: loopback-test: add ability to test zero-length transfer ... Browse Code »

    The spi-loopback-test module currently cannot test the spi_message
    including a zero-length transfer. Because the zero-length transfer is
    treated as a special value in several meanings.

    1. The number of spi_transfer to execute in one test case is described
    by spi_test.transfer_count. It is normally computed by counting number
    of transfers with len > 0 in spi_test.transfers array.

    This change stops the detection for the number of spi_transfer. Each
    spi_test.transfer_count needs to be filled by hand now.

    2. The spi_test.iterate_len is a list of transfer length to iterate on.
    This list is terminated by zero, so zero-length transfer cannot be
    included.

    This changes the terminal value from 0 to -1.

    3. The length for the spi_transfer masked by spi_test.iterate_transfer_mask
    is iterated. Before starting the iteration, the default value which
    is statically initialized is applied. In order to specify the default
    value, zero-length is reserved.

    Currently, the default values are always '1'. So this removes this
    trick and add '1' to iterate_len list.

    By applying all these changes, the spi-loopback-test can execute spi
    messages with zero-length transfer.

  • 84e0c4e5e   spi: add loopback test driver to allow for spi_master regression tests ... Browse Code »

    This driver is submitting lots of distinct spi-messages messages
    with all kinds of alignments and length pattern.
    Also distinct kinds of transfer pattern tests are implemented
    (rx, tx, rx/tx, tx+tx, tx+rx,...)

    Right now on a raspberry pi 752 distinct spi_messages are executed
    in 13 different scenarios.

    Configuration of additional test-pattern is easy, so that when
    new bugs in drivers get detected the relevant transfer pattern can
    also get added to the test framework, so that such situations are
    detected in other drivers as well.

    The idea behind this driver is to make it possible to also detect
    regressions in spi_master implementations when changes occur.
    Potentially these tests could get executed automatically in a
    test-server-farm.
