2008-04-02videobuf: Avoid deadlock with QBUF and bring up to spec for empty queueBrandon Philips
Add a waitqueue to wait on when there are no buffers in the buffer queue. DQBUF waits on this queue without holding vb_lock to allow a QBUF to happen. Once a buffer has been queued we recheck that the queue is still streaming and wait on the new buffer's waitqueue while holding the vb_lock. The driver should come along in a timely manner and put the buffer into its next state finishing the DQBUF. By implementing this waitqueue it also brings the videobuf DQBUF up to spec and it now blocks on O_NONBLOCK even when no buffers have been queued via QBUF: "By default VIDIOC_DQBUF blocks when no buffer is in the outgoing queue." - V4L2 spec CC: Trent Piepho <xyzzy@speakeasy.org> CC: Carl Karsten <carl@personnelware.com> CC: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Brandon Philips <bphilips@suse.de> --- linux/drivers/media/video/videobuf-core.c | 96 +++++++++++++++++++++++------- linux/include/media/videobuf-core.h | 2 2 files changed, 78 insertions(+), 20 deletions(-)
2008-04-02videobuf-vmalloc.c: Fix hack of postponing mmap on remap failureBrandon Philips
In videobuf-vmalloc.c remap_vmalloc_range is failing when applications are trying to mmap buffers immediately after reqbuf. It fails because the vmalloc area isn't setup until the first QBUF when drivers call iolock. This patch introduces mmap_setup to the qtype_ops and it is called in __videobuf_mmap_setup if the buffer type is mmap. In the case of vmalloc buffers this calls iolock, and sets the state to idle. I don't think this is needed for dma-sg buffers and it defaults to a no-op for everything but vmalloc.

2008-03-24 soc-camera: improve separation between soc_camera_ops and soc_camera_deviceMauro Carvalho Chehab
From: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> In case of muliple cameras, handled by the same driver, they can support different picture formats, therefore formats and num_formats cannot belong to soc_camera_ops, which is only one per driver, move them to soc_camera_device, which is one per device instance. OTOH, probe and remove methods are always the same, move them to soc_camera_ops.

From: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Only attach cameras to the host interface for probing, then detach until open. This allows platforms with several cameras on an interface, physically supporting only one camera, to handle multiple cameras and activate them selectively after initial probing. The first attach during probe is needed to activate the host interface to be able to physically communicate with cameras.

2008-02-05 soc_camera V4L2 driver for directly-connected SoC-based camerasMauro Carvalho Chehab
From: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> This driver provides an interface between platform-specific camera busses and camera devices. It should be used if the camera is connected not over a "proper" bus like PCI or USB, but over a special bus, like, for example, the Quick Capture interface on PXA270 SoCs. Later it should also be used for i.MX31 SoCs from Freescale. It can handle multiple cameras and / or multiple busses, which can be used, e.g., in stereo-vision applications.

2008-02-02Fix Kconfig dependenciesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes. This patch moves the functions that videodev needs from v4l2-common. It also fixes some Kconfig changes. After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked into kernel. v4l2-common will be m, and all V4L drivers will also be m. This approach is very conservative, since it is possible to have V4L drivers that don't need I2C or v4l2-common. The better is to map what drivers really need v4l2-common, making them to select v4l2-common, and allowing the others to be 'y', 'm' and 'n'.
