This patch adds em28xx-dvb. This driver is highly based on cx88-dvb and saa7134-dvb. This code currently loads and unloads successfully. However, some changes are needed to properly support the mpeg streams and to setup em28xx to work on DVB mode. Signed-off-by: -

The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. A simplified version of the semantic patch making this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @ change_compare_np @ expression E; @@ ( - jiffies <= E + time_before_eq(jiffies,E) | - jiffies >= E + time_after_eq(jiffies,E) | - jiffies < E + time_before(jiffies,E) | - jiffies > E + time_after(jiffies,E) ) @ include depends on change_compare_np @ @@ @ no_include depends on !include && change_compare_np @ @@ #include <linux/...> + #include <linux/jiffies.h> // </smpl> Signed-off-by:

The patch extends the default keymap of FlyVIdeo2000 IR remote control so that this remote may also serve movie & music players in a better way. I bought a SAA7130 TV tuner with a remote control having 3 additional button as the default layout, exactly as: 1) labeled "<<<" : key code 0x19, may be used as "backward"in MPlayer,XMMS etc 2) labeled ">>>" : key code 0x1f, may be used as "forward"... 3) not labeled : key code 0x0a, may be used as "pause"... Once have added these code definitions to the kernel, me got all these operations available for viewing movies & listening music. Signed-off-by : Ivan Bobyr <brefi@yandex.ru> Signed-off-by: -

This patch modifies Dmitri's original ibmcam driver for Linux to improve support for the IBM PC Camera Pro. It may also offer improved support for other models classified by the driver as 'Model 3', such as the IBM PC Camera Pro Max. See http://auricle.dyndns.org/xvp610/Signed-off-by:

Observation one: ->write_proc and ->data assignments aren't needed. Removed. Observation two: codecs lists are unprotected. Patch doesn't fix this. Observation three: /proc/videocodecs printout is done to temporary _global_ buffer which is freed in between. Consequently, two users hitting this file can screwup each other. Steps to reproduce: modprobe videocodec while true; do cat /proc/videocodecs &>/dev/null; done & while true; do cat /proc/videocodecs &>/dev/null; done & The fix is switching to seq_files, this removes code, especially some line-length "logic".

Due to the patch order change, pvrusb2 were broken. So, changeset 4c3b01f7 were applied at mainstream to fix. After the pvrusb2 changes, this patch is no longer required and should be reverted. Signed-off-by:

Correct the frequency of the emitted diseqc signal to 22kHz. Adds sleep(100) to wait for message to be transmitted. For now the only user of mt312 is b2c2-flexcop, and it does overwrite all diseqc related functions with own code. Signed-off-by:

This device is a clone of the PN1010 used by SkyStar2 rev2.7 . This patch adds support for the flexcop-device and makes the driver look a little bit nicer. It needs to be checked whether the driver is still ok for the budget-cards. Signed-off-by:

Removes some fields from data structs. There are some fields that are just caching some calculus for buffer size. The calculus were moved to the places it were needed and the now unused fields were removed. Signed-off-by: -

videobuf-dvb were still using a function that were videobuf-dma-sg dependent. This patch creates a generic handler for this function. This way, videobuf-dvb can now work with all videobuf implementations. Signed-off-by: -

This patch fixes three related issues and a fourth trivial one: - Use buffers even if no-one's currently waiting for them (fixes underrun issues); - Don't return incomplete/mangled frames at the start of streaming and in the case of buffer underruns; - Fix an issue which could cause the driver to write to a buffer that's been freed after videobuf_queue_cancel is called (exposed by the previous two fixes - for some reason, ignoring buffers that weren't being waited on worked around the issue); - Fix a bug which could cause only one field to be filled in the first buffer (or first few buffers) after streaming is started.

There are some cases where nobody is waiting for a buffer. Due to the lack of check, if you try to abort the userspace app, machine were hanging, since IRQ were trying to use a buffer that were disallocated. Signed-off-by: -

A spinlock is necessary for queue_cancel to work with every driver in the tree. Otherwise a race exists between IRQ handlers removing buffers from the queue and queue_cancel invalidating the queue. Signed-off-by:

Currently, vidioc_s_fmt_cap is allowed even if streaming is running on some other fh. This is likely to cause issues. Block use of vidioc_s_fmt_cap if someone else has claimed access to the device. Signed-off-by:

There were a small bug on videobuf-vmalloc that were preventing STREAMOFF to work. The issue is that vmalloc'ed mmaped memory should only be freed after being sure that there aren't any mmap usage. Otherwise, the memory remap will stop working, and the userspace won't receive any frames. This bug were affecting some userspace applications, like tvtime. After this patch, tvtime started to work again with the drivers that use videobuf-vmalloc. Signed-off-by: -

There were some bugs on videobuf-vmalloc. Basically, remap were called with a wrong parameter. Due to that, a later remap were needed, generating the need of some hacks on videobuf-vmalloc and videobuf-core. This patch fixes the remap and removes the hacks. TODO: - V4L2_MEMORY_USERPTR is not implemented yet. This method should be properly implemented, in order to work with a few userspace applications. - The driver also doesn't implement V4L2_MEMORY_OVERLAY. This method is used only by a few applications, and are becaming obsolete, due to the increment of cpu performance. So, most apps prefer to retrieve data to an internal buffer, doing some processing like de-interlacing. Signed-off-by: -

I did notice a possible memory leak since iolock is could possibly be called before a buffer has been freed. This ensure s_fmt isn't called while the queue is busy thereby avoiding iolock on already allocated buffers. Signed-off-by:

- Aborting buffer_filled if no-one's waiting on the waitqueue probably isn't what we want, since just because no-one's waiting for it now doesn't mean they wouldn't dequeue it in time. (vivi gets away with this, possibly because it can fill each buffer much faster.) - The first BUG_ON(lencopy <= 0); really isn't worth causing a kernel panic over, especially since there are some reasons why it could trigger in normal use. - The top and botom frames are actually the wrong way around.
