* V4L/DVB (9244): video: improve sh_mobile_ceu buffer handlingMagnus Damm2008-10-171-1/+14
| | | | | | | | | | | | | | This patch improves the buffer handling in the sh_mobile_ceu driver. Instead of marking all queued buffers as VIDEOBUF_ACTIVE the code now marks queued-but-not-active buffers as VIDEOBUF_QUEUED and buffers involved in dma as VIDEOBUF_ACTIVE. The code is also updated with code to cancel active buffers, thanks to Morimoto-san.

* V4L/DVB (9235): Precalculate vivi yuv valuesMagnus Damm2008-10-171-59/+58
| | | | | | | | | | | | | This patch improves the color space conversion code in vivi.c to directly draw with precalculated YUV values as palette instead of drawing with YUV that is calculated from RGB for every two pixels. This way we eliminate the need for 9 multiplications every two pixels. A side effect of this patch is that the time counter is changed from green text on black background to white text on black background.

* V4L/DVB (9232): cx23885: Move the MFE frontend allocation into the correct placeSteven Toth2008-10-171-22/+41
| | | | | | | | | | | | | | cx23885 frontend allocation code needs to exist in the higher function, and it also needs to ensure videobug is also correctly initialised on a per frontend basis. This code uses the previous num_frontends patch to safely init each future MFE frontend on a single tsport as as safely as possible - given that we don't have any of those boards. Again, better to add all of this safety code now, while the MFE patch set is fresh in everyone mind, than to try and add it 12-24 months from now, when the subject is cold.

| | | | | | | | | | This allows some cardcoded functions to be more flexible, and paves the way for any future cards that may have MFE support.

* V4L/DVB (9229): cx88: Add intial config for FM radio supportDarron Broad2008-10-171-3/+11
| | | | | | | | | | | | | | | This add initial configuration for radio support on the hvr-3000/4000. FM radio doesn't work as yet without further patches (to come), but this prepares for that. Experimental radio support shows that it works when combined with additional audio routing work for cards with an FMD1216ME analogue frontend, but not the MEX variant (more later).

* V4L/DVB (9228): cx88: Add audio routing for the hvr-3000/4000Darron Broad2008-10-172-1/+9
| | | | | | | | | | | | | | | | | | | | This adds audio routing on the hvr-3000/4000 This is a preliminary patch for later routing requirements. This adds line-in support on the 2 cards mentioned. It is also apparent that there is an initial open fault for line-in when opening composite/s-video. This will be fixed later. It was also noticed that the bit-field for audio routing which was 2 bits needs an increase as the WM8775 for example, allows a value 4 bits wide for it's audio mux.

* V4L/DVB (9227): MFE: Add multi-frontend mutual exclusionDarron Broad2008-10-178-15/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | This add frontend R/W mutual exclusion. Prior to this point in time it was possible to open both frontends simultaneously which an MFE card cannot support. In order to stop this, a delayed open is performed which has the following function: - Return EBUSY after a configurable amount of time if a frontend is unavailable due to the other being in use. - Only allow opening of a frontend if the kernel thread of the other has stopped. This solution was chosen to allow switching between frontends to work as seamlessly as possible. When both frontends are actually opened simultaneously then one will only open, but if quick switching is performed between one of many then the new open will succeed in a clean fashion rather than interrupting a kernel thread.

| | | | | | | | | | | | This adds a configurable (one per card) gate control option for multi-frontend. Prior to this point gate control was assumed to be on the primary frontend, this is a fault when the gate to the analogue section is on the secondary which is the default for both the HVR-3000 and HVR-4000 in MFE.

| | | | | | | | | | | | | | A number of reference to videobuf_dvb_get_frontend used an invalid index. This has been fixed. The section for the HVR3000 in advise_acquire was redundant as the same logic is used on the HVR4000. This has been removed and both cards now use the same function.

* V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support.Steven Toth2008-10-1714-319/+713
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A detailed description from the original patches 2 years ago: "The WinTV-HVR3000 has a single transport bus which is shared between a DVB-T and DVB-S modulator. These patches build on the bus acquisition cx88 work from a few weeks ago to add support for this. So to applications the HVR3000 looks like this: /dev/dvb/adapter0/fe0 (cx24123 DVB-S demod) /dev/dvb/adapter0/fe1 (cx22702 DVB-T demod) Additional boards continue as before, eg: /dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod) The basic change is removing the single instance of the videobuf_dvb in cx8802_dev and saa7134_dev(?) and replacing it with a list and some supporting functions. *NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so two or three current cx88 patches appear to be reversed by this tree, this will be cleaned up in the near future. The patches missing change the mutex handing to core->lock, fix an enumeration problem." It should be recognised that a number of people have been maintaining this patchset. Significant levels of Kudos to everyone one involved, including but not limited to: Darron Broad Fabio M. Di Nitto Carlo Scarfoglio Hans Werner Without the work of these people, and countless others, my two year old patches would of died on the Mercurial linuxtv.org vine a long time ago. TODO: Revise these patches a little further so that the need for demux1 and dvr0 is optional, not mandatory on the HVR3000. HISTORY (darron): This is the last update to MFE prepared by Hans which is based upon the `scratchpad' diff created by Carlo. All MFE work prior to that point must be attributed to Fabio who ported and maintained Steve's original patch up to that time.

| | | | | | | | | | | | | | | | This patch removes the unnecessary get/set input/audio functions. The reason is, that the V4L2 specification says, that if input or audio cannot be switched anyway, the functions doesn't need to be implemented. I've tested the new driver with all current radio programs in Debian/testing and found no problems with that. In my opinion, the driver is much cleaner by removing these unnecessary functions.

| | | | | | | | | | | | | | | This patch changes the handling of unsupported base controls. In the former version, specific unsupported base controls were listed in the queryctrl table and were flagged as disabled controls. This was done for all base controls used by the applications.

| | | | | | | | | | | | | This patch improves support for multiple radio devices. In previous versions all region relevant settings were derived from one module parameter. As in future versions, the region and other configuration should be configurable per device from the user space, this patch already retrieves all relevant information from the actual device specific settings.
