  • 03b1930ef   V4L/DVB: saa7146: fix regression of the av7110/budget-av driver ... Browse Code »

    An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
    regression where v4l2_device was registered too late) caused a new
    regression in the av7110 driver.

    Reverted the old fix and fixed the problem in the mxb driver instead.
    Tested on mxb and budget-av cards.

    The real problem is that the saa7146 framework has separate probe()
    and attach() driver callbacks which should be rolled into one. This
    is now done for the mxb driver, but others should do the same. Lack
    of hardware makes this hard to do, though. I hope to get hold of some
    hexium cards and then I can try to improve the framework to prevent
    this from happening again.

    v4l2_device_register needs to be called before the i2c subdevs are loaded.
    However, it was called afterwards in the saa7146 driver. This caused an oops
    when loading the mxb and hexium drivers. The vv_init function is now split
    into two: one registers the v4l2_device, the other does the rest of the
    initialization. The three drivers that depend on this have been updated to
    call the new vv_devinit function.

    Thanks to Michael Hunold for reporting this.

  • 327ae5975   V4L/DVB (13557): v4l: Remove unneeded video_device::minor usage in drivers ... Browse Code »

    The video_device::minor field is used where it shouldn't, either to

    - test for error conditions that can't happen anymore with the current
    v4l-dvb core,
    - store the value in a driver private field that isn't used anymore,
    - check the video device type where video_device::vfl_type should be
    used, or
    - create the name of a kernel thread that should get a stable name.

    Remove or fix those use cases.

  • 069b74793   V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl. ... Browse Code »

    Since internal to v4l2 the ioctl prototype is the same regardless of it
    being called through .ioctl or .unlocked_ioctl, we need to convert it all
    to the long return type of unlocked_ioctl.

    Thanks to Jean-Francois Moine for posting an initial patch for this and
    thus bringing it to our attention.

  • bec43661b   V4L/DVB (10135): v4l2: introduce v4l2_file_operations. ... Browse Code »

    Introduce a struct v4l2_file_operations for v4l2 drivers.

    Remove the unnecessary inode argument.

    Move compat32 handling (and llseek) into the v4l2-dev core: this is now
    handled in the v4l2 core and no longer in the drivers themselves.

    Note that this changeset reverts an earlier patch that changed the return
    type of__video_ioctl2 from int to long. This change will be reinstated
    later in a much improved version.

  • c1accaa21   V4L/DVB (6252): Adapt drivers to use the newer videobuf modules ... Browse Code »

    PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo.

    Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct.
    So, to access it, a subroutine call is needed.

    This patch renames all occurences of those function calls to be
    consistent with the video-buf split.

    Olaf Hering pointed out that SAA7146_CLIPPING_MEM would become
    very large for PAGE_SIZE > 4K.
    In fact, the number of clipping windows is limited to 16,
    and calculate_clipping_registers_rect() does not use more
    than 256 bytes. SAA7146_CLIPPING_MEM adjusted accordingly.

  • c7b0ac054   V4L/DVB (3516): Make video_buf more generic ... Browse Code »

    Video_buf were concerned to allow PCI devices to be used as
    video capture devices. This patch extends video_buf features
    by virtualizing pci-dependent functions and allowing other
    type of devices to use it.
    It is still DMA centric, although it may be used also by
    devices that emulates scatter/gather behavior or a DMA device

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
