    Commit fa41d10589be ("fpga: dfl-pci: locate DFLs by PCIe vendor specific
    capability") provides documentation to the FPGA Device Feature List (DFL)
    Framework Overview, but introduced new documentation warnings:

    ./Documentation/fpga/dfl.rst:
    505: WARNING: Title underline too short.
    523: WARNING: Unexpected indentation.
    523: WARNING: Blank line required after table.
    524: WARNING: Block quote ends without a blank line; unexpected unindent.

    Rectify ReST formatting in ./Documentation/fpga/dfl.rst.

  • 113094f74   docs: add some directories to the main documentation index ... Browse Code »

    The contents of those directories were orphaned at the documentation
    body.

    While those directories could likely be moved to be inside some guide,
    I'm opting to just adding their indexes to the main one, removing the
    :orphan: and adding the SPDX header.

    For the drivers, the rationale is that the documentation contains
    a mix of Kernelspace, uAPI and admin-guide. So, better to keep them on
    separate directories, as we've be doing with similar subsystem-specific
    docs that were not split yet.

    For the others, well... I'm too lazy to do the move. Also, it
    seems to make sense to keep at least some of those at the main
    dir (like kbuild, for example). In any case, a latter patch
    could do the move.

    The dfl.txt file is almost there. It needs just a few
    adjustments to be properly parsed.

    The conversion is actually:
    - add blank lines and identation in order to identify paragraphs;
    - fix tables markups;
    - add some lists markups;
    - mark literal blocks;
    - adjust title markups.

    At its new index.rst, let's add a :orphan: while this is not linked to
    the main index.rst file, in order to avoid build warnings.

  • ebf877a51   fpga: mgr: separate getting/locking FPGA manager ... Browse Code »

    Previously when the user gets a FPGA manager, it was locked
    and nobody else could use it for programming.

    This commit makes it straightforward to save a reference to an
    FPGA manager and only lock it when programming the FPGA.

    Add functions that get an FPGA manager's mutex for exclusive use:
    * fpga_mgr_lock
    * fpga_mgr_unlock

    The following functions no longer lock an FPGA manager's mutex:
    * of_fpga_mgr_get
    * fpga_mgr_get
    * fpga_mgr_put

  • 5cf0c7f65   fpga: mgr: API change to replace fpga load functions with single function ... Browse Code »

    fpga-mgr has three methods for programming FPGAs, depending on
    whether the image is in a scatter gather list, a contiguous
    buffer, or a firmware file. This makes it difficult to write
    upper layers as the caller has to assume whether the FPGA image
    is in a sg table, as a single buffer, or a firmware file.
    This commit moves these parameters to struct fpga_image_info
    and adds a single function for programming fpgas.

    New functions:
    * fpga_mgr_load - given fpga manager and struct fpga_image_info,
    program the fpga.

    * fpga_image_info_alloc - alloc a struct fpga_image_info.

    * fpga_image_info_free - free a struct fpga_image_info.

    These three functions are unexported:
    * fpga_mgr_buf_load_sg
    * fpga_mgr_buf_load
    * fpga_mgr_firmware_load

    Also use devm_kstrdup to copy firmware_name so we aren't making
    assumptions about where it comes from when allocing/freeing the
    struct fpga_image_info.

    API documentation has been updated and a new document for
    FPGA region has been added.

  • baa6d3966   fpga: Add scatterlist based programming ... Browse Code »

    Requiring contiguous kernel memory is not a good idea, this is a limited
    resource and allocation can fail under normal work loads.

    This introduces a .write_sg op that supporting drivers can provide
    to DMA directly from dis-contiguous memory and a new entry point
    fpga_mgr_buf_load_sg that users can call to directly provide page
    lists.

    The full matrix of compatibility is provided, either the linear or sg
    interface can be used by the user with a driver supporting either
    interface.

    A notable change for drivers is that the .write op can now be called
    multiple times.

  • 1d7f1589d   fpga: Clarify how write_init works streaming modes ... Browse Code »

    This interface was designed for streaming, but write_init's buf
    argument has an unclear purpose. Define it to be the first bytes
    of the bitstream. Each driver gets to set how many bytes (at most)
    it wants to see. Short bitstreams will be passed through as-is, while
    long ones will be truncated.

    The intent is to allow drivers to peek at the header before the transfer
    actually starts.

  • 40e83578f   doc: fpga-mgr: add fpga image info to api ... Browse Code »

    This patch adds a minor change in the FPGA Manager API
    to hold information that is specific to an FPGA image
    file. This change is expected to bring little, if any,
    pain.

    An FPGA image file will have particulars that affect how the
    image is programmed to the FPGA. One example is that
    current 'flags' currently has one bit which shows whether the
    FPGA image was built for full reconfiguration or partial
    reconfiguration. Another example is timeout values for
    enabling or disabling the bridges in the FPGA. As the
    complexity of the FPGA design increases, the bridges in the
    FPGA may take longer times to enable or disable.

    This patch documents the change in the FPGA Manager API
    functions, replacing the 'u32 flag' parameter with a pointer
    to struct fpga_image_info.
