2009-01-02V4L/DVB (10135): v4l2: introduce v4l2_file_operations.Hans Verkuil
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.

This cleans-up the advise/acquire methods. This has been tested on the hvr-1300/4000 and assumed to be correct on the hvr-3000. This update also fixes analogue tuning on the hvr-1300 when in blackbird mode.

2008-10-21V4L/DVB (9327): v4l: use video_device.num instead of minor in video%dHans Verkuil
The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.

2008-01-25V4L/DVB (6828): cx88-blackbird: audio improvementsJelle Foks
This patch should fix the 'muted audio' and 'raspy audio' problem for mpeg2 streams out of cx88-blackbird devices. Especially mythtv users would find that the audio would often sound bad (aliased, or 'raspy'), mainly related to channel changes, many (all?) other users would find that there was no audio at all in the mpeg data from the encoder chip, unless the audio was manually unmuted. The patch includes the following modifications: Don't actually start the mpeg2 encoder until the device is read from by the application. Wait until the audio is stable for at least 400ms before starting the mpeg encoder. Mute/Unmute the audio when starting/stopping the mpeg encoder. Stop the mpeg encoder when changing parameters and when changing tuner frequency. Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of whether or not the mpeg2 encoder is active. Load the firmware on cx88-blackbird driver load.

2007-10-09V4L/DVB (6088): cx2341x: some controls can't be changed while the device is busyHans Verkuil
The driver should now pass the 'busy' state of the device to the cx2341x module whenever controls are set or tried. -EBUSY will be returned if the device is busy and the user attempts to modify certain 'dangerous' controls. It concerns controls that change the audio or video compression mode and bitrates. The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy) to the cx2341x, effectively keeping the old behavior for now.

2007-10-09V4L/DVB (6021): cx88: Copy board information into card stateTrent Piepho
The cx88 driver state stored the ID of the board type in core->board. Every time the driver need to get some information about the board configuration, it uses the board number as an index into board configuration array. This patch changes it so that the board number is in core->boardnr, and core->board is a copy of the board configuration information. This allows access to board information without the extra indirection. e.g. cx88_boards[core->board].mpeg becomes core->board.mpeg. This has a number of advantages: - The code is simpler to write. - It compiles to be smaller and faster, without needing the extra array lookup to get at the board information. - The cx88_boards array no longer needs to be exported to all cx88 modules. - The boards array can be made const - It should be possible to avoid keeping the (large) cx88_boards array around after the module is loaded. - If module parameters or eeprom info override some board configuration setting, it's not necessary to modify the boards array, which would affect all boards of the same type.

2006-12-10V4L/DVB (4676): Dynamic cx88 mpeg port management for HVR1300 MPEG2/DVB-T ↵Steven Toth
support. A series of patches to change the cx88 framework to allow the PCI mpeg port to be shared dynamically between different types of drivers or applications. This patch changes the cx88-dvb and cx88-blackbird drivers to become 'sub drivers' of a higher single cx88-mpeg driver. The cx88-mpeg driver is a superset of the previous cx88-mpeg/blackbird drivers and now owns the IRQ. cx88-dvb/blackbird now become mini drivers, registering themselves with cx88-mpeg through a standard interface with callbacks. Sub drivers request access to hardware via the cx88-mpeg driver. In turn the cx88-mpeg driver determines whether the hardware is busy and accepts or refuses the request, grant access using callbacks into the sub drivers. The net effect is that you are no longer able to tamper with the mpeg port from multiple different applications at the same time, potentially breaking a live mpeg2 hardware encoding or dvb stream. The mechanism extends to enable multiple dvb frontends to be registered and share the single resource.
