* V4L/DVB (9227): MFE: Add multi-frontend mutual exclusionDarron Broad2008-10-171-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* V4L/DVB (9225): MFE: Add configurable gate controlDarron Broad2008-10-171-0/+1
| | | | | | | | | | | | 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.

* V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support.Steven Toth2008-10-171-3/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* V4L/DVB (9133): v4l: disconnect kernel number from minorHans Verkuil2008-10-121-10/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | The v4l core creates four different video devices (video, vbi, radio, vtx) and each has its own range of minor numbers. However, modern devices keep increasing the number of devices that they need so a maximum of 64 video devices will not be enough in the future. In addition this scheme makes it very hard to add new device types. This patch disconnects the kernel number allocation (e.g. video0, video1, etc.) from the actual minor number (just pick the first free minor). This allows for much more flexibility in the future. However, it does require the use of udev. For those who cannot use udev a new CONFIG option was created that changes the allocation scheme back to the old behavior. Thanks to Greg KH for suggesting this approach during the 2008 LPC. In addition, several bugs were fixed in the ivtv and cx18 drivers: these drivers try to allocate specific kernel numbers but that scheme contained a bug which caused what should have been e.g. video17 to appear as e.g. video2.

* V4L/DVB (8625): saa7134: Add NEC prococol IR decoding capabilityMauro Carvalho Chehab2008-10-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the capability of decoding NEC protocol, received via GPIO18 line. This GPIO port can trigger saa7134 IRQ. A future improvement would be to make it a little more generic to work also with GPIO16 line. A pure IRQ code didn't work, since some delays were introduced on the tests we did. A possible approach would be to use polling at a rate of 2.5 ms or less. If a new code were taken, a code similar to nec_task() could be used. However, this would add an extra overhead to kernel, and will consume more power. Due to that, we took an hybrid approach: an IRQ upper half to trigger when a new key is received and a bottom half to convert pulse-distance into a keycode. The bottom half is polling based, to improve performance. During the bottom half proccess, GPIO18 IRQ line is disabled, preventing IRQ reentrancy and improving performance a little bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is V3 of the physically contiguous videobuf queues patch. Useful for hardware such as the SuperH Mobile CEU which doesn't support scatter gatter bus mastering. Since it may be difficult to allocate large chunks of physically contiguous memory after some uptime due to fragmentation, this code allocates memory using dma_alloc_coherent(). Architectures supporting dma_declare_coherent_memory() can easily avoid fragmentation issues by using dma_declare_coherent_memory() to force dma_alloc_coherent() to allocate from a certain pre-allocated memory area. Changes since V2 - use dma_handle for physical address - use "scatter gather" instead of "scatter gatter" Changes since V1: - use dev_err() instead of pr_err() - remember size in struct videobuf_dma_contig_memory - keep struct videobuf_dma_contig_memory in .c file - let videobuf_to_dma_contig() return dma_addr_t - implement __videobuf_sync() - return statements, white space and other minor fixes Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
