* V4L/DVB (5603): V4L: Prevent queueing queued buffers.Sakari Ailus2007-05-09
| | | | | | | | | | | videobuf_qbuf queues buffers to q->stream but does not properly check the state of the buffer before queueing. It was possible to queue buffers that already were in the queue. Only buffers that are in states STATE_NEEDS_INIT and STATE_IDLE can be queued. Signed-off-by: Sakari Ailus <sakari.ailus@nokia.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (5147): Make vivi driver to use vmalloced pointersMauro Carvalho Chehab2007-02-21
| | | | | | | | | | | | | | | | | | | | | Before this patch, vivi were simulating a scatter gather DMA transfer. While this is academic, showing how stuff really works on a real PCI device, this means a non-optimized code. There are only two memory models that vivi implements: 1) kernel alloced memory. This is also used by read() method. On this case, a vmalloc32 buffer is allocated at kernel; 2) userspace allocated memory. This is used by most userspace apps. video-buf will store this pointer. a simple copy_to_user is enough to transfer data. The third memory model scenario supported by video-buf is overlay mode. This model is not implemented on vivi and unlikely to be implemented on newer drivers, since now, most userspace apps do some post-processing (like de-interlacing). After this patch, some cleanups may be done at video-buf.c to avoid allocating pages, when the driver doesn't need a PCI buffer. This is the case of vivi and usb drivers.

* V4L/DVB (5123): Buf_qbuf: fix: videobuf_queue->stream corruption and lockupOleg Nesterov2007-01-23
| | | | | | | | We are doing ->buf_prepare(buf) before adding buf to q->stream list. This means that videobuf_qbuf() should not try to re-add a STATE_PREPARED buffer. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (3516): Make video_buf more genericMauro Carvalho Chehab2006-03-24
| | | | | | | | | | | Video_buf were concerned to allow PCI devices to be used as video capture devices. This patch extends video_buf features by virtualizing pci-dependent functions and allowing other type of devices to use it. It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* [PATCH] vfree and kfree cleanup in drivers/Jesper Juhl2005-09-10
| | | | | | | | | | | | This patch does a full cleanup of 'NULL checks before vfree', and a partial cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in that I only did the files that also had vfree calls in them. The patch also gets rid of some redundant (void *) casts of pointers being passed to [vk]free, and a some tiny whitespace corrections also crept in.

Still on development tree. - linux/version dependencies removed. - BTSC Lang1 now is set to auto_stereo mode. - New tuner standby API. - i2c-core.c uses hexadecimal for the i2c address, so it should stay consistent.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
