2008-04-24V4L/DVB (7610): em28xx: Select reg wait time based on chip IDMauro Carvalho Chehab
This is more conservative than just removing the msleep() from em28xx_write_regs_req(), since some old hardware may still need it. So, it will remove the sleep time only for those chips where this removal were tested. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7609): em28xx-core: speed-up firmware loadDevin Heitmueller
em28xx-core.c: - Remove sleep in i2c message routine which slows down i2c by a factor 10x. Load time for BASE firmware went from 13s to .973s Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7608): em28xx-dvb: Some cleanups and fixesDevin Heitmueller
em28xx-dvb.c: - Remove unneeded xc3028_ctrl structure. The driver automatically preserves the previous value tuner-xc2028.c: - Make the return type for xc2028_get_reg signed, since all of the callers are looking for "< 0" to detect errors.

2008-04-24V4L/DVB (7603): em28xx-dvb: don't use videobuf-dvbAidan Thornton
Modifies em28xx-dvb not to use videobuf-dvb, but instead to include the code for registering dvb devices locally and use the URB management code in the em28xx driver directly. DVB data streaming should now work. Signed-off-by: Aidan Thornton <makosoft@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7602): em28xx: generalise URB setup codeAidan Thornton

2008-04-24V4L/DVB (7598): em28xx: several fixes on gpio programmingDevin Heitmueller
em28xx-cards.c: - Fix reversed val/rst values in both analog_gpio and digital_gpio vectors - Fix crash that would was occurring during every analog startup while looping over gpio_ctl - Remove what appears to be a redundant setting of gpio_ctl->val - Don't use OREN538 demodulation for the HVR-950 (prevents ATSC scanning from working) em28xx-dvb.c: - Tuner should be in digital mode when issuing the reset - Add copyright - Change struct definition (corresponds to fix in em28xx-cards.c for gpio_ctl looping) Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-04-24V4L/DVB (7593): em28xx: add a module to handle dvbMauro Carvalho Chehab
This patch adds em28xx-dvb. This driver is highly based on cx88-dvb and saa7134-dvb. This code currently loads and unloads successfully.

2008-04-24V4L/DVB (7590): ir-common: Adds 3 missing IR keys for FlyVIdeo2000Ivan Bobyr
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"...

2008-04-24V4L/DVB (7580): Fix concurrent read from /proc/videocodecsAlexey Dobriyan
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".

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.

2008-04-24V4L/DVB (7567): em28xx: Some cleanupsMauro Carvalho Chehab

2008-04-24V4L/DVB (7566): videobuf-dvb: allow its usage with videobuf-vmallocMauro Carvalho Chehab

2008-04-24V4L/DVB (7565): em28xx: fix buffer underrun handlingAidan Thornton
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.

2008-04-24V4L/DVB (7563): em28xx: Add missing checksMauro Carvalho Chehab
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: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7562): videobuf: Require spinlocks for all videobuf usersBrandon Philips
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.

2008-04-24V4L/DVB (7561): videobuf-vmalloc: stop streaming before unmapMauro Carvalho Chehab

2008-04-24V4L/DVB (7553): videobuf-vmalloc: fix STREAMOFF/STREAMONMauro Carvalho Chehab
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: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7552): videbuf-vmalloc: Corrects mmap codeMauro Carvalho Chehab
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: Mauro Carvalho Chehab <mchehab@infradead.org>
