for that all I give some examples further below. > Second clarification, PCI versus cardbus. > They don't look anything like each other, but can they be logically > interchangeable?

No, we do such and vice versa, but then we add a comment PCI or cardbus version usually and another important compatible category is Mini PCI. You should also add LR306 as the board type. > Looking at <http://www.linuxtv.org/wiki/index.php/DVB-T_PCMCIA_Cards> > there does not appear to be any such thing as a > SAA7134_BOARD_FLYDVBT_HYBRID_CARDBUS, despite the entry (number 94) > in saa7134.h.

They do exist, see bttv-gallery.de, also Mauro has already a MSI OEM version. They are special for DVB-T, since they switch the mode by a gpio pin and have the silent i2c connection to the tuner open and don't use the i2c gate of the tda8290 analog demod inside the saa7131e for DVB-T tuning. > Should > "SAA7134_BOARD_FLYDVBT_HYBRID_CARDBUS" be changed to > "SAA7134_BOARD_FLYDVBT_HYBRID"? No. Just also add "PCI" and "LR306" to your comments. The gpio 21 is used for the TV/radio switch. The gpio 22 = 0 in the mask is used to switch the tuner AGC to the analog demod. On some cardbus version, which have the gpio 27 high, switching it to 0 turns the fan on, on yours it does nothing, since it is 0 anyway. > It appears that both PCI and cardbus versions of the Flytv duo exist > and are listed in saa7134.h - despite slightly inconsistent punctuation; > SAA7134_BOARD_FLYDVBTDUO versus > SAA7134_BOARD_FLYDVBT_DUO_CARDBUS. > > Should > "SAA7134_BOARD_FLYDVBTDUO" be changed to > "SAA7134_BOARD_FLYDVBT_DUO"? Not related to your device. Subdevice is 0x0306 and you have 0x3306, but yes, these are in a different family of devices too. > I have an MSI [EMAIL PROTECTED] A/D PCI card that works with the option > card=94 > > There appears to not be an entry in struct pci_device_id saa7134_pci_tbl[] > in saa7134-cards.c for my card. There is a reference to a > "[EMAIL PROTECTED] DUO" which I guess is a valid entry for a different card. Yes it is. Peter Missel bought some and added the entry. Duo in LifeView terminology means two separate tuners. One for analog TV/FM and one for DVB-T. On the older Duo versions those two tuners were _not hybrid_ and different for analog TV and DVB-T. Only the newer Duo variants with tda8275A use two identical such tuners, but not in hybrid mode. One is always in analog and the other always in digital mode. The older types are out of production and using two still allows to have DVB-T and analog TV from the tuners at once. This is not possible with one single hybrid tuner. DVB-T and analog video from an external input, VCR tuner or something, is possible at once, but needs also to use packed video formats for analog during that due to limitations of the dma engines with planar formats. Then the Trio has even one more tuner for DVB-S, but there is only _one_ saa713x PCI bridge on all such and only one channel decoder/demodulator for each mode. Since the single saa713x chip has only one TS/mpeg/host interface, either usable in parallel or serial mode, DVB-S and DVB-T can not be used at the same time. (also not an mpeg encoder) This is only possible with two saa713x bridges, like the md7134 in the CTX925 version has them and when we enable DVB-S support on the second bridge hopefully soon. Else functionality is like on the Trio. (BTW, the md7134 represents lots of different cards through eeprom detection) Next category is the Medion md8800 Quad(ro) with two saa7131e, two fully usable tda8275ac1 hybrid (2 analog + 2 DVB-T demods, no FM) and two tda8263 DVB-S tuners plus two tda10086 channel decoders plus an isl6405 dual LNB controller, where we just have support of the first SAT connector now, diseqc for multiswitches is not fully tested yet. There is RF loopthrough, in and out, respectively to the other. So it should be already possible to view and record from both DVB-S devices at once, within that tunable spectrum the active one limits for the passive by controlling tone and LNB voltage. That loopthrough can be switched off, for example when we have active control for the second SAT connector too. On the two hybrid tuners the RF feed can also be switched, either to loopthrough mode from TV1 antenna connector to both tuners or have input of choice from both analog/DVB-T antenna connectors separately. > Is the entry; > > { > .vendor = PCI_VENDOR_ID_PHILIPS, > .device = PCI_DEVICE_ID_PHILIPS_SAA7133, > .subvendor = 0x4e42, > .subdevice = 0x3502, > .driver_data = SAA7134_BOARD_FLYDVBT_HYBRID_CARDBUS > }, > > supposed to be; > > { > .vendor = PCI_VENDOR_ID_PHILIPS, > .device = PCI_DEVICE_ID_PHILIPS_SAA7133, > .subvendor = 0x4E42, /* MSI */ > .subdevice = 0x3306, /* [EMAIL PROTECTED] Hybrid > A/D */ > driver_data = SAA7134_BOARD_FLYDVBT_HYBRID_CARDBUS, > }, > > with the subdevice changed, or possibly; > > { > .vendor = PCI_VENDOR_ID_PHILIPS, > .device = PCI_DEVICE_ID_PHILIPS_SAA7133, > .subvendor = 0x4E42, /* MSI */ > .subdevice = 0x3306, /* [EMAIL PROTECTED] Hybrid > A/D */ > driver_data = SAA7134_BOARD_FLYDVBT_HYBRID, > }, > > with the subdevice and driver_data changed, or should there be an extra > entry in the list? We have no SAA7134_BOARD_FLYDVBT_HYBRID, this would require already the new entry. The 4e42:3502 is Mauro's MSI TV @nywhere A/D NB cardbus and likely other OEMs too. On the subdevice 0x3306 are the related PCI cards and 0x3307 are Mini PCI. Thought you did not pick up my patch suggestion that time, http://www.linuxtv.org/pipermail/linux-dvb/2007-June/018678.html because we had no means to make a difference to the Vivanco 21056 and we did not get the analog TV mode right on it. For the i2c remote with mdt10p55 (pic 16c505) Eddi had a patch. We talked about it and remaining implementation questions, but should be usable for you in private if you replace the appearance of SAA7134_BOARD_FLYDVB_TRIO with your device or add it accordingly. Since the cardbus and mini pci devices seem not to have a remote so far, this could eventually rise the question of a separate entry later on IMHO.
