2009-01-07V4L/DVB (10190): cx88: Fix some Kbuild troublesMauro Carvalho Chehab
As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues: drivers/built-in.o: In function `cx88_call_i2c_clients': (.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend' drivers/built-in.o: In function `cx8802_probe': cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend' cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends' With those configs: CONFIG_VIDEO_CX88=y CONFIG_VIDEO_CX88_BLACKBIRD=y CONFIG_VIDEO_CX88_DVB=m CONFIG_DVB_CORE=m After carefully examining the code, with the current code, several cx88 drivers (cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module, if one of them is marked as such. Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.

2009-01-02V4L/DVB (10141): v4l2: debugging API changed to match against driver name ↵Hans Verkuil
instead of ID. Since the i2c driver ID will be removed in the near future we have to modify the v4l2 debugging API to use the driver name instead of driver ID. Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only. Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged with a warning that it is deprecated and will be removed in 2.6.30.

Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

2008-12-30V4L/DVB (9796): drivers/media/video/cx88/cx88-alsa.c: Adjust error-handling codeJulia Lawall
In the function cx88_audio_initdev, the value card has been created using snd_card_new. The other error handling code in this function frees the value using snd_card_free. I have thus changed the first error case to do the same. On the other hand, it may be that card is not sufficiently initialized at this point to use snd_card_free, in which case something else should be done to free the memory in the error case. In the function snd_cx88_create the call kfree(chip) in one error case looks suspicious, both because it is not done in the other error code, and because chip points into the middle of the memory allocated by snd_card_new, ie it is not itself associated with a separate kmalloc. Therefore I have removed it. The semantic match that finds the first problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S,S1; position p1,p2,p3; expression E,E1; type T,T1; expression *ptr != NULL; @@ ( if ((x@p1 = snd_card_new(...)) == NULL) S | x@p1 = snd_card_new(...); ) ... when != snd_card_free(...,(T)x,...) when != if (...) { <+... snd_card_free(...,(T)x,...) ...+> } when != true x == NULL || ... when != x = E when != E = (T)x when any ( if (x == NULL || ...)

2008-12-16V4L/DVB (9885): drivers/media Kconfig's: fix bugzilla #12204Mauro Carvalho Chehab
When the tuner modules were moved to common/tuners, a separate customize option were added for tuners. However, the automatic selection of the tuners were still using the older option. This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the tuners. This patch fixes this error by replacing DVB_FE_CUSTOMISE by MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected. The patch were generated by this small script: for i in `find drivers/media -name Kconfig`; do cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a mv a $i done Also, manually reordered the tuner entries.

2008-11-11V4L/DVB (9357): cx88-dvb: Fix Oops in case i2c bus failed to registerMatthias Schwarzott
There already is an report at kernel bugzilla about this issue: http://bugzilla.kernel.org/show_bug.cgi?id=9455 When enabling extra checks for the i2c-bus of cx88 based cards by loading i2c_algo_bit with bit_test=1 this may trigger an oops when loading cx88_dvb. This is caused by the extra check code that detects that the sda-line is stuck high and thus does not register the i2c-bus. cx88-dvb however does not check if the i2c-bus is valid and just uses core->i2c_adap to attach dvb frontend modules. This leads to an oops at the first call to i2c_transfer: $ modprobe i2c_algo_bit bit_test=1 $ modprobe cx8802 cx88/2: cx2388x MPEG-TS Driver Manager version 0.0.6 loaded cx88[0]: quirk: PCIPCI_NATOMA -- set TBFX cx88[0]: subsystem: 0070:9202, board: Hauppauge Nova-S-Plus DVB-S [card=37,autodetected], frontend(s): 1 cx88[0]: TV tuner type 4, Radio tuner type -1 cx88[0]: SDA stuck high! cx88[0]: i2c register FAILED input: cx88 IR (Hauppauge Nova-S-Plus as /class/input/input5 cx88[0]/2: cx2388x 8802 Driver Manager cx88-mpeg driver manager 0000:00:10.2: enabling device (0154 -> 0156) cx88-mpeg driver manager 0000:00:10.2: PCI INT A -> Link[LNKD] -> GSI 9 (level, low) -> IRQ 9 cx88[0]/2: found at 0000:00:10.2, rev: 5, irq: 9, latency: 64, mmio: 0xfb000000 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: 0070:9202, board: Hauppauge Nova-S-Plus DVB-S [card=37] cx88[0]/2: cx2388x based DVB/ATSC card BUG: unable to handle kernel NULL pointer dereference at 00000000 IP: [<e084d4ef>] :i2c_core:i2c_transfer+0x1f/0x80 *pde = 00000000 Modules linked in: cx88_dvb(+) cx8802 cx88xx ir_common i2c_algo_bit tveeprom videobuf_dvb btcx_risc mga drm ipv6 fscpos eeprom nfsd exportfs stv0299 b2c2_flexcop_pci b2c2_flexcop cx24123 s5h1420 ves1x93 dvb_ttpci dvb_core saa7146_vv saa7146 videobuf_dma_sg videobuf_core videodev v4l1_compat ttpci_eeprom lirc_serial lirc_dev usbhid rtc uhci_hcd 8139too i2c_piix4 i2c_core usbcore evdev Pid: 4249, comm: modprobe Not tainted (2.6.27-gentoo #3) EIP: 0060:[<e084d4ef>] EFLAGS: 00010296 CPU: 0 EIP is at i2c_transfer+0x1f/0x80 [i2c_core] EAX: 00000000 EBX: ffffffa1 ECX: 00000002 EDX: d6c71e3c ESI: d80cd050 EDI: d8093c00 EBP: d6c71e20 ESP: d6c71e0c DS: 007b ES: 007b FS: 0000 GS: 0033 SS: 0068 Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-21V4L/DVB (9327): v4l: use video_device.num instead of minor in video%dHans Verkuil
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.

This adds I2S-ADC tvaudio mode as a formal method of audio delivery. This fixes one bug and adds fm audio via I2S-ADC on cards that support it. The bug occured before when I2S-ADC mode was initiated on composite/s-video open but was then reset within 500ms by the audio thread which used any previous audio tuning details.

This add initial configuration for radio support on the hvr-3000/4000. FM radio doesn't work as yet without further patches (to come), but this prepares for that. Experimental radio support shows that it works when combined with additional audio routing work for cards with an FMD1216ME analogue frontend, but not the MEX variant (more later).

This adds audio routing on the hvr-3000/4000 This is a preliminary patch for later routing requirements. This adds line-in support on the 2 cards mentioned. It is also apparent that there is an initial open fault for line-in when opening composite/s-video. This will be fixed later. It was also noticed that the bit-field for audio routing which was 2 bits needs an increase as the WM8775 for example, allows a value 4 bits wide for it's audio mux.

2008-10-17V4L/DVB (9227): MFE: Add multi-frontend mutual exclusionDarron Broad
This add frontend R/W mutual exclusion. Prior to this point in time it was possible to open both frontends simultaneously which an MFE card cannot support. In order to stop this, a delayed open is performed which has the following function: - Return EBUSY after a configurable amount of time if a frontend is unavailable due to the other being in use. - Only allow opening of a frontend if the kernel thread of the other has stopped. This solution was chosen to allow switching between frontends to work as seamlessly as possible. When both frontends are actually opened simultaneously then one will only open, but if quick switching is performed between one of many then the new open will succeed in a clean fashion rather than interrupting a kernel thread.

This adds a configurable (one per card) gate control option for multi-frontend.

A number of reference to videobuf_dvb_get_frontend used an invalid index. This has been fixed. The section for the HVR3000 in advise_acquire was redundant as the same logic is used on the HVR4000.

2008-10-17V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support.Steven Toth
A detailed description from the original patches 2 years ago: "The WinTV-HVR3000 has a single transport bus which is shared between a DVB-T and DVB-S modulator. These patches build on the bus acquisition cx88 work from a few weeks ago to add support for this. So to applications the HVR3000 looks like this: /dev/dvb/adapter0/fe0 (cx24123 DVB-S demod) /dev/dvb/adapter0/fe1 (cx22702 DVB-T demod) Additional boards continue as before, eg: /dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod) The basic change is removing the single instance of the videobuf_dvb in cx8802_dev and saa7134_dev(?) and replacing it with a list and some supporting functions. *NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so two or three current cx88 patches appear to be reversed by this tree, this will be cleaned up in the near future. The patches missing change the mutex handing to core->lock, fix an enumeration problem." It should be recognised that a number of people have been maintaining this patchset. Significant levels of Kudos to everyone one involved, including but not limited to: Darron Broad Fabio M. Di Nitto Carlo Scarfoglio Hans Werner Without the work of these people, and countless others, my two year old patches would of died on the Mercurial linuxtv.org vine a long time ago. TODO: Revise these patches a little further so that the need for demux1 and dvr0 is optional, not mandatory on the HVR3000. HISTORY (darron): This is the last update to MFE prepared by Hans which is based upon the `scratchpad' diff created by Carlo. All MFE work prior to that point must be attributed to Fabio who ported and maintained Steve's original patch up to that time.

2008-10-12V4L/DVB (9135): cx88 Dvico FusionHDTV ProTim Farrington
Well, one thing you encouraged me to do was re-test some of my cards which contained the xc3028-zarlink combo. Which led me to test a Dvico FusionHDTV Pro. Almost a year ago, Chris Pascoe did a patch for this which can be found at his ~pascoe/xc-test at Linuxtv. This worked very well, however that was using his version of firmware. Alas, someone attempted to use this and patch v4l-dvb, and messed it up. So I've fixed it. I enclose the patch against today's tree (containing your latest tuner-xc2028.c patch). The card now works very well, well with DVB-T anyway. Signed-off-by: Tim Farrington <timf@iinet.net.au> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

This patch against latest mercurial makes DVB-T working on Pinnacle Hybrid PCTV Pro (pctv310c). In cx88-dvb.c, a specific zl10353_config is created with the if2 inferred from the old comment in the currently used config. It is then used for attach, and i2c_gate_ctrl is set to NULL. The entry in cx88-cards.c is modified with GPIO gathered from windows with regspy, and DVB enabled. The frontend is set to XC3028_FE_ZARLINK456 to match the zl10353_config. It is working great with the freeview channels I can receive. Signed-off-by: Stéphane Voltz <stef.dev@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
