  • 32958fdd1   [media] BKL: trivial BKL removal from V4L2 radio drivers ... Browse Code »

    The patch converts a bunch of V4L2 radio drivers to unlocked_ioctl.

    These are all simple conversions: most already had a lock and so the ioctl
    fop could simply be replaced by unlocked_ioctl.

    radio-miropcm20.c was converted to use the new V4L2 core lock.

    While doing this work I noticed that many of these drivers initialized
    some more fields or muted audio or something like that *after* creating
    the device node. This should be done before the device node is created
    to prevent problems. Especially hal tends to grab a device node as soon
    as it is created.

    In one or two cases the mutex_init was even done after the device creation!

  • 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.

  • fa027c2a0   [PATCH] mark struct file_operations const 4 ... Browse Code »

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 0d0fbf815   V4L (926_2): Moves compat32 functions from fs to v4l subsystem ... Browse Code »

    This moves the 32 bit ioctl compatibility handlers for
    Video4Linux into a new file and adds explicit calls to them
    to each v4l device driver.

    Unfortunately, there does not seem to be any code handling
    the v4l2 ioctls, so quite often the code goes through two
    separate conversions, first from 32 bit v4l to 64 bit v4l,
    and from there to 64 bit v4l2. My patch does not change
    that, so there is still much room for improvement.

    Also, some drivers have additional ioctl numbers, for
    which the conversion should be handled internally to
    that driver.

    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!
