2008-05-20Fix a deadlock in the bttv driverArjan van de Ven
vidiocgmbuf() does this: mutex_lock(&fh->cap.vb_lock); retval = videobuf_mmap_setup(&fh->cap, gbuffers, gbufsize, V4L2_MEMORY_MMAP); and videobuf_mmap_setup() then just does mutex_lock(&q->vb_lock); ret = __videobuf_mmap_setup(q, bcount, bsize, memory); mutex_unlock(&q->vb_lock); which is an obvious double-take deadlock. This patch fixes this by having vidiocgmbuf() just call the __videobuf_mmap_setup function instead.

2008-05-14V4L/DVB (7851): Fix FW_LOADER depencency at v4l/dvbMauro Carvalho Chehab
Since: 1) FW_LOADER is defined as: config FW_LOADER tristate "Userspace firmware loading support" depends on HOTPLUG 2) several V4L/DVB driver just selects it; 3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER. So, All drivers that select FW_LOADER should also depend on HOTPLUG. An easier solution (for the end-user perspective) would be to "select HOTPLUG". However, live is not simple. This would cause recursive dependency issues like this one: drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD -> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA -> USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

It has a large chip in the middle labeled CONEXANT FUSION 878A 25878-13 E345881.1 0312 TAIWAN It has an audio connector coming out from a chip labeled ATMEL 0242 AT89C2051-24PI It is identified as follows on my Debian GNU/Linux Etch (kernel 2.6.18) ... 01:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 01:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) ... 01:0a.0 0400: 109e:036e (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dfffe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 01:0a.1 0480: 109e:0878 (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dffff000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18 kernel and the latest v4l-dvb drivers, but it did not work at all. The card has sixteen (16) BNC video inputs, four of them on the board itself and twelve on three daughter-cards. It has a single bt878 chip, no tuner and what looks like and audio input. After doing some research I managed to get only eight channels working by forcing card=125 and those DID NOT match channels 0-7 on the card, and no audio. Based on what was working for card=125, I added the card definition block, added a specific muxsel routine and got the card working fully with xawtv, where the sixteen channels show up as Composite0 to Composite15, matching the channel labels in the card and daughter-cards. I have made no efforts yet to get audio working, but would appreciate any pointers. Signed-off-by: Ernesto Hernández-Novich <emhn@usb.ve> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7294): : tuner and radio addresses are missing for the PixelView ↵Wojciech Migda
PlayTV card The PixelView PlayTV card definition structure was missing initialization of the tuner_addr and radio_addr fields. As a result it was impossible to have the tuner initialized using parameters specified while loading the bttv.ko module. This regression became visible after the v4l rearrangements introduced somewhere around 2.6.15 kernel version. The root cause for the tuner initialization failure is located in the attach_inform function in the bttv-i2c.c file. There at the very beginning the addr variable holding the tuner device address is initialized with the value taken from the bttv_tvcards array. For the PixelView PlayTV card the tuner address field (and the radio address as well) was uninitialized, and thus equal 0. Later in that function execution of the TUNER_SET_TYPE_ADDR tuner command is guarded with check for the tuner address either equal ADDR_UNSET, or client->addr. Since both are non-zero (the latter in case of the card owned by me at the runtime is equal 0x61) the TUNER_SET_TYPE_ADDR command is not executed, and consequently in the tuner_attach function in the tuner-core.c file call to i2c_attach_client does not result in assigning the tuner type variable with the requested value. Providing initialization of the tuner_addr and radio_addr with ADDR_UNSET values as it is already done for other tv cards defined in bttv-cards.c ensures that the tuner initialization is done correctly, just as it used to be in the 2.6.14 kernel.
