* media video cx23888 driver: ported to new kfifo APIStefani Seibold2009-12-221-25/+19
| | | | | | | | | | | | | Fix the cx23888 driver to use the new kfifo API. Using kfifo_reset() may result in a possible race conditions. This patch fixes it by using a spinlock around the kfifo_reset() function.

* kfifo: fix warn_unused_resultStefani Seibold2009-12-221-2/+3
| | | | | | | | | | | | | | | | | | | Fix the "ignoring return value of '...', declared with attribute warn_unused_result" compiler warning in several users of the new kfifo API. It removes the __must_check attribute from kfifo_in() and kfifo_in_locked() which must not necessary performed. Fix the allocation bug in the nozomi driver file, by moving out the kfifo_alloc from the interrupt handler into the probe function. Fix the kfifo_out() and kfifo_out_locked() users to handle a unexpected end of fifo.

* kfifo: move out spinlockStefani Seibold2009-12-221-15/+20
| | | | | | | | | | | | | | | Move the pointer to the spinlock out of struct kfifo. Most users in tree do not actually use a spinlock, so the few exceptions now have to call kfifo_{get,put}_locked, which takes an extra argument to a spinlock.

* kfifo: move struct kfifo in placeStefani Seibold2009-12-222-27/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new generic kernel FIFO implementation. The current kernel fifo API is not very widely used, because it has to many constrains. Only 17 files in the current 2.6.31-rc5 used it. FIFO's are like list's a very basic thing and a kfifo API which handles the most use case would save a lot of development time and memory resources. I think this are the reasons why kfifo is not in use: - The API is to simple, important functions are missing - A fifo can be only allocated dynamically - There is a requirement of a spinlock whether you need it or not - There is no support for data records inside a fifo So I decided to extend the kfifo in a more generic way without blowing up the API to much. The new API has the following benefits: - Generic usage: For kernel internal use and/or device driver. - Provide an API for the most use case. - Slim API: The whole API provides 25 functions. - Linux style habit. - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros - Direct copy_to_user from the fifo and copy_from_user into the fifo. - The kfifo itself is an in place member of the using data structure, this save an indirection access and does not waste the kernel allocator. - Lockless access: if only one reader and one writer is active on the fifo, which is the common use case, no additional locking is necessary. - Remove spinlock - give the user the freedom of choice what kind of locking to use if one is required. - Ability to handle records. Three type of records are supported: - Variable length records between 0-255 bytes, with a record size field of 1 bytes. - Variable length records between 0-65535 bytes, with a record size field of 2 bytes. - Fixed size records, which no record size field. - Preserve memory resource. - Performance! - Easy to use! This patch: Since most users want to have the kfifo as part of another object, reorganize the code to allow including struct kfifo in another data structure. This requires changing the kfifo_alloc and kfifo_init prototypes so that we pass an existing kfifo pointer into them. This patch changes the implementation and all existing users.

* V4L/DVB (13658): v4l: add a media-bus API for configuring v4l2 subdev pixel ↵Guennadi Liakhovetski2009-12-162-1/+158
| | | | | | | | | | | | | | | | | | | | | | | and frame formats Video subdevices, like cameras, decoders, connect to video bridges over specialised busses. Data is being transferred over these busses in various formats, which only loosely correspond to fourcc codes, describing how video data is stored in RAM. This is not a one-to-one correspondence, therefore we cannot use fourcc codes to configure subdevice output data formats. This patch adds codes for several such on-the-bus formats and an API, similar to the familiar .s_fmt(), .g_fmt(), .try_fmt(), .enum_fmt() API for configuring those codes. After all users of the old API in struct v4l2_subdev_video_ops are converted, it will be removed. Also add helper routines to support generic pass-through mode for the soc-camera framework. create mode 100644 drivers/media/video/soc_mediabus.c create mode 100644 include/media/soc_mediabus.h create mode 100644 include/media/v4l2-mediabus.h Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (13612): IR: Move common IR code to drivers/media/IRMauro Carvalho Chehab2009-12-161-4/+0
| | | | | | | | | | | | This is the first step of creating a common code for IR that can be used by other input devices. For now, keep IR dir at drivers/media, to easy the movement of the IR files, but later patches may move it to drivers/IR or drivers/input/IR. No functional changes is done on this patch.

* V4L/DVB (13598): videobuf_dma_contig_user_get() for non-aligned offsetsMuralidharan Karicheri2009-12-161-2/+4
| | | | | | | | | | | | | | | | | | If a USERPTR address that is not aligned to page boundary is passed to the videobuf_dma_contig_user_get() function, it saves a page aligned address to the dma_handle. This is not correct. This issue is observed when using USERPTR IO machism for buffer exchange. Updates from last version:- Adding offset for size calculation as per comment from Magnus Damm. This ensures the last page is also included for checking if memory is contiguous.

* V4L/DVB (13597): bttv: add i2c addr for old WinTV card to IR probe listJarod Wilson2009-12-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are old bttv-driven Hauppauge WinTV series cards that have their IR part at i2c addr 0x71, which doesn't get considered in the new 2.6.31 i2c code. From a 2.6.29 kernel: lirc_i2c: chip 0x10005 found @ 0x71 (Hauppauge PVR150) Minor cosmetic glitch, the card in question isn't actually a PVR-150, its: 03:06.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) Subsystem: Hauppauge computer works Inc. WinTV Series Flags: bus master, medium devsel, latency 32, IRQ 19 Memory at f4ffe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 Kernel driver in use: bttv Kernel modules: bttv Device ID: 0x109e:0x036e, Sub-Device ID: 0x0070:0x13eb This simply adds 0x71 to the list of addresses i2c_new_probed_device should consider, which gets IR working on this card again.
