* V4L/DVB (10527): tuner: fix TUV1236D analog/digital setupMauro Carvalho Chehab2009-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by David Engel <david@istwok.net>, ATSC115 doesn't work fine with mythtv. This software opens both analog and dvb interfaces of saa7134. What happens is that some tuner commands are going to the wrong place, as shown at the logs: Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01 This happens due to a hack at TUV1236D analog setup, where it replaces tuner address, at 0x61 for 0x0a, in order to save a few memory bytes. The code assumes that nobody else would try to access the tuner during that setup, but the point is that there's no lock to protect such access. So, this opens the possibility of race conditions to happen. Instead of hacking tuner address, this patch uses a temporary var with the proper tuner value to be used during the setup. This should save the issue, although we should consider to write some analog/digital lock at saa7134 driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (10170): tuner-simple: prevent possible OOPS caused by divide by ↵Michael Krufky2009-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | zero error A user reported the following OOPS with his pcHDTV HD5500 card, which uses a cx88 PCI bridge with a LG-TDVS-H06xF frontend module, made up of a TUA6034 tuner, TDA988x IF demod, and LG DT3303 ATSC/QAM demod. Somehow, tuner-core gets loaded before the digital driver configures the tuner, and tuner-core somehow incorrectly sets the tuner type to LG NTSC (TAPE series) instead of LG TDVS-H06xF. This tuner type does not have the tuning stepsize defined, so an OOPS occurs during the digital tune function. We still dont know how the type gets set incorrectly in the first place. The user has a tainted kernel with a binary nividia module, which COULD have something to do with this, but it's hard to say for sure. Nevertheless, to avoid this division by zero, we should check that stepsize is defined. If stepsize is not defined, print an error and bail out on the tune request. cx8800 0000:05:01.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]: subsystem: 7063:5500, board: pcHDTV HD5500 HDTV [card=47,autodetected], frontend(s): 1 cx88[0]: TV tuner type 47, Radio tuner type -1 tuner' 2-0043: chip found @ 0x86 (cx88[0]) tda9887 2-0043: creating new instance tda9887 2-0043: tda988[5/6/7] found tuner' 2-0061: chip found @ 0xc2 (cx88[0]) tuner-simple 2-0061: creating new instance tuner-simple 2-0061: type set to 47 (LG NTSC (TAPE series)) cx88[0]/0: found at 0000:05:01.0, rev: 5, irq: 19, latency: 32, mmio: 0xea000000 cx88[0]/0: registered device video1 [v4l2] cx88[0]/0: registered device vbi1 cx88_audio 0000:05:01.1: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]/1: CX88x/0: ALSA support for cx2388x boards cx88[0]/2: cx2388x 8802 Driver Manager cx88-mpeg driver manager 0000:05:01.2: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]/2: found at 0000:05:01.2, rev: 5, irq: 19, latency: 32, mmio: 0xec000000 cx8802_probe() allocating 1 frontend(s) cx88/2: cx2388x dvb driver version 0.0.6 loaded cx88/2: registering cx8802 driver, type: dvb access: shared cx88[0]/2: subsystem: 7063:5500, board: pcHDTV HD5500 HDTV [card=47] cx88[0]/2: cx2388x based DVB/ATSC card tuner-simple 2-0061: attaching existing instance tuner-simple 2-0061: type set to 64 (LG NTSC (TAPE series)) tda9887 2-0043: attaching existing instance DVB: registering new adapter (cx88[0]) DVB: registering adapter 0 frontend 0 (LG Electronics LGDT3303 VSB/QAM Frontend)...

| | | | | | | | | | | | | | | Probably due to a removed code, tda827x were doing some wrong calculus at the returned frequency. I suspect that the original idea were to return the programmed divisor converted into frequency again. However, the current code is sometimes multiplying the programmed frequency by 62500, and, on other cases, like radio, it dividing it by 1000. Instead of doing such math, let's just store the frequency value as requested by the caller module. Cc: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

* V4L/DVB (9055): tuner-xc2028: Do a better job selecting firmware typeMauro Carvalho Chehab2008-10-12
| | | | | | | | | | Firmware selection is very tricky on this device. This patch do a better selection of the proper firmware type, by using a code to hint if the firmware to be loaded should be D2620 or D2633. It also allows overriding the hint at the control structure. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | Dont pass devptr in xc5000_attach, dont store it in xc5000_priv. This pointer is passed into the tuner_callback function, which always expects a pointer to fe->dvb->priv or i2c_adapter->algo_data. This prevents future possible bugs in new drivers, such as using a "devptr" other that the standard fe->dvb->priv in a DVB driver.

| | | | | | | | | | | | | | | | digital is in use Prevent an OOPS if xc5000_attach was called by tuner.ko before being called by the DVB adapter driver. The OOPS occurs when a digital tune request is made after tuner.ko is unloaded. When tuner.ko is unloaded, it takes the xc5000_config structure with it. Rather than storing a pointer to the xc5000_config structure, just store the if_khz and tuner_callback inside the xc5000_priv internal state structure.

* V4L/DVB (8546): saa7146: fix read from uninitialized memoryHans Verkuil2008-07-27
| | | | | | | | | | | | | | | | The offset field of the scatterlist entry *after* the last valid scatterlist entry was used instead of the first scatterlist entry (as was the intention of this code). This worked fine until the kzalloc of the sglist was replaced with kmalloc and sg_init_table only zeroed the exact needed length. Apparently kzalloc zeroes a bit more than is strictly necessary so the offset field was always 0 in the past. But now the offset field was suddenly random and this led to broken captures.
