I have finally managed to get the CI support for the card working. The implementation is a bare minimum to get encrypted channels to work in kaffeine. It works fine with my T/CI card. Now and then I get an AVC timeout and have to retune a channel in order to get it to work. Once the CAM seemed to hang so I needed to remove and insert it again. I.e. there are a number of glitches. The latest version contains the following changes: - Implemented the new hpsb iso interface so that data can be received from the card - Reduced some timers for demux setup which caused scanning to timeout - Added possibility to unload driver - Added support for getting C/N ratio - Added two debug parameters to the driver; ca_debug and avc_comm_debug. - Added CI support that works for me in kaffeine - Started working on CI MMI support. It now supports: o Enter menu o Receiving MMI objects - Added support for 64-bit platforms - Corrected DVB-C modulations problems Signed-off-by: NHenrik Kurelid <henrik@kurelid.se> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (rebased, whitespace)

The video_ioctl2 conversion of ivtv in kernel 2.6.27 introduced a bug causing decoder commands to crash. The decoder commands should have been handled from the video_ioctl2 default handler, ensuring correct mapping of the argument between user and kernel space. Unfortunately they ended up before the video_ioctl2 call, causing random crashes. Thanks to hannes@linus.priv.at for testing and helping me track down the cause!

If a device using the gspca framework is unplugged while it is still streaming then the call that is used to free the URBs that have been allocated occurs after the pointer it uses becomes invalid at the end of gspca_disconnect. Make another cleanup call in gspca_disconnect while the pointer is still valid (multiple calls are OK as destroy_urbs checks for pointers already being NULL.

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: NMauro Carvalho Chehab <mchehab@redhat.com>

Just like with the s5h1411, the s5h1409 needs a soft-reset in order for it to know that the tuner has been told to change frequencies. This change changes the behavior from "random tuning times between 500ms to complete tuning lock failures" to "tuning lock consistently within 700ms".

V4L/DVB (10265): budget.c driver: Kernel oops: "BUG: unable to handle kernel paging request at ffffffff I'm using a "Hauppauge WinTV-NOVA-T DVB card" of PCI id "13c2:1005" with kernel 2.6.27.9. I've recently experienced the following fairly consistent kernel oops on startup in grundig_29504_401_tuner_set_params from budget.c. As you might expect, following this failure, the card doesn't work. I'm not a kernel developer, nevertheless I seem to have managed to track this down to a non-existent initialisation of budget->dvb_frontend->tuner_priv. The attached patch fixes the problem for me (and I've managed to tune the card successfully as a result), but I don't know of anyone else using the driver so I can't test it on other people.

The hardware of the stick has changed, when compared to the first version of this stick, but it still uses quite standard components, so that only minor changes are needed to the sources. The patch has been successfully tested with hotplugging the device and then 2 x tzap and 2 x mplayer, to watch two different TV programs simultaneously.

Some em28xx devices use the PCM IN AC 97 PIN for digital audio. However, currently, the PCM IN selection is not set by the driver. This patch allows specifying the PCM IN expected output, via board description table. Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The zoran driver does a module_get/put of THIS_MODULE on device open/close. This isn't necessary as the kernel does this automatically. Clean up the failure path of zoran_open() somewhat. Make the dprintk()s on open/close a higher debug level and make the user count printed take the current open/close into account.

The driver should only use the kernel mapped io address, zr36057_mem, and not the PCI bus address, zr36057_adr. Since the latter is only printed out once, there is no need to save it in the driver data structure. There was some old code that looked like it was for the Alpha architecture which would use the PCI bus address. It probably no longer applies to modern kernels.

Instead of using custom code, just let the device layer look it up for us from the pci device table. This requires extending the pci device table to list each known card, plus a catch-all entry for the cards that don't have sub-system vendor/device data. Improve some of the info and error messages too.

The driver was keeping a global array with an entry for each zoran device probed. It was a leftover from when the driver didn't dynamically allocate the driver data for each device. There was only one use left, in the video device's ->open() method, looking up the struct zoran for the opened device from the minor number. This can be done better with video_get_drvdata(). Since zoran_num is now only used in the pci driver's ->probe() method, it doesn't need to be an atomic_t and be static. There is a race if multiple zoran cards could be probed at the same time, but currently the probe method for a given driver is single threaded.

When initializing a module parameter that is a per-card array, use "{ [0 ... (BUZ_MAX-1)] = -1 }" instead of "{ -1, -1, -1, -1 }". This way all of the entries will be correctly set to -1 if someone changes BUZ_MAX to a value other than 4. Adjust some of the parameter help text too.

When enabling a shared IRQ line, then saa7134_irq handler could be invoked before the driver had completely set up internal structures, due to a shared interrupt line firing. Clear the saa7134 interrupt status reg, before requesting the irq line, so that stale IRQ status isn't processed before the internal structures are set up. Marcin Slusarz recently brought this Oops to the attention of the v4l-dvb lists and provided an initial analysis by investigating reports found here: http://kerneloops.org/guilty.php?guilty=mute_input_7133&version=2.6.27-release&start=1802240&end=1835007&class=oopsReported-by: NMarcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: NAndy Walls <awalls@radix.net> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>
