I believe that what you call lirc core will be used always - it is the code that create3s class devices, connectes decorers with the data streams, etc. I believe it will be utilized even in case of devices using hardware decoders. That is why we should probably stop calling it "lirc core" just tso we don't confuse it with original lirc. Then we have decoders and lirc_dev - which implements original lirc interface (or maybe its modified version) and allows lircd to continue working. Lastly we have what you call IR core which is IR-to-input bridge of sorts.

Right, currently there is no need to query all scancodes defined by
device. Quite often drivers don't even know what scancodes device
actually generates (ex AT keyboard).
Could you describe in more detail how you are using this data?

Can we probably reduce the "scancode" space? ARe all 64 bits in

Sometimes we just need to say that the device is a POS and is just not worth it. Remember, there is still "lirc hole" for the hard core people still using solder to produce something out of the spare electronic components that may be made to work (never mind that it causes the CPU constantly poll the device, not letting it sleep and wasting electricity as a result - just hypotetical example here). We still need to do cost-benefit analysis and decide whether supporting the exotic setups _in kernel_ makes sense if it encumbers implementation and causes issues to the other 95% people. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

By looking on your code, as you're calling: ir_input_init(input_dev, &ir->ir, ir_type, ir_codes); You'll already be using my new code. However, you'll need to add a call to ir_input_free(input_dev), at the IR unregistering code, and on an error condition. You should notice that you're not limited to use only 128 scancodes from 0 to 127, as the previous versions of the ir-common allowed. The new version supports 32 bits for scancodes, and use dynamic allocation to allow adding/removing codes from the table.

Yes, I agree. I do not know what percentage of current Linux users are technical vs non-technical, so I cannot gauge the current improtance.

"Recommended hardware" to guide users is usually an acceptable concept. I have a feeling though, we may end up with a lot of "hey I got this remote and video card on eBay and ..." If the in kernel IR Rx handling is going to be really limited in trying to "keep it simple", then that remote control hardware recommendation should probably be strictly "the remote bundled with your IR receiver hardware" to handle the most important use case for the in kernel IR Rx handling to meet. > I'm not proposing that we prevent arbitrary remotes from working, > you're just going to need to expend more effort to make them work. > For example, you have to have a fair amount of IR knowledge to figure > out why those two cases above don't work.

At least one vendor, has shipped two different type of remote with the same board over the years. Also MCE versions of cards usually ship with an MCE remote versus the standard one. I think it still could be possible to avoid a user interview process, but I suspect you'll need a userspace set of "scripting" tools to take detection data from the kernel and select the right kepymap. > When the v4l drivers load they could even poke the default map for > their bundled remotes directly into the input system if they wanted > to. Doing that might save a lot of config issues. They do that right now (well some of them and ir-kbd-i2c). But there is *no* intelligence beyond the most current or popular remote for a board. Also, some things require things a manual or scripted module load by the user: ir-kbd-i2c and lirc_i2c can't currently hook to the same I2C device at once, so the user has to set one or the other up to be loaded. > How this for new goals? > Specific IR drivers autoload maps for their bundled remotes by > poking them into the input subsystem during module load > IR always has default map for a universal remote - it provides five > devices and uses a common protocol like JVC (may not work for fixed > hardware, you have to set these five common devices into the universal > remote) > All of these maps can be overriden with user space commands (which > lets you configure funky remotes) This looks like it just adds the option for the user to trade away mental effort with purchasing power (for a universal remote). Not an unacceptable trade for many people I guess. I suppose it gives the user one option than he had before, if you have a target set of universal remote hardware. I'd like to see some vendor diversity in that target set of "just works" universal remotes. My whole thought on t

It is weird to call ir_input_free during the boot. This means that something
got wrong during IR initialization.
Anyway, I think I know here's the bug: the first thing the routine does is this:
struct ir_scancode_table *rc_tab = input_get_drvdata(dev);
However, if ir_input_init() doesn't initialize fine, rc_tab will be null.
Could you please test if the enclosed patch fixes the issue?

[em28xx] BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 IP: [] :ir_common:ir_input_free+0x26/0x3e
Hi All, Tried to update my v4l-dvb modules today, but got a bug with my pinnacle card, seems to be related to the recent changes in the ir code.

There are lots of comments that aren't following C99 specs. Also, some code is indented with 4 spaces, instead of tabs, making really hard to read the code, among several other codingstyle violations.

The call should be generic, something like get_property_signalstats ...

You're contradicting yourself: by using S2API, the userspace API won't be using a single structure, since S2API will break them into pairs of attributes/values. Nothing limits that the in-kernel API will group those values into a struct, but the internal API should be smart enough to not return to userspace the values that weren't requested by the call.

help with cx88 blackbird
I need some help trying to get a second tuner card setup, the card is a Kworld mce 201, it has a conexant cx23416-12 and a conexant 23880-19 chips the tuner is a TNJ7751-MFF . I am running Ubuntu 8.04 with mythtv fixes .21. The card is found as an anolog V4l capture card by mythtv but the Mpeg-2 encoder part isnt found. Dmesg says that the card type is unknown and to add it to the modeprobe.d options file, but I am unsure witch card to choose, I have tried card 45 which loads it as device video3 ( I have to manually enter the video device number in mythtv backend to make it show the probed info) but when I switch to this tuner on a frontend it just sits on a black screen for a few minutes then returns to the mythtv menu. I can use Mplayer from the command line using mplayer -vo xv /dev/video3 the Mplayer window opens but all I get is colored snow. In case it matters my other cards that work with mythtv are a Hauppauge PVR 350 and an ATI TV Wonder dvb card. any help with this would be appreciated. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Support of Gotview X5 3D card
Hello, I have Gotview X5 3D Hybrid PCI-E card (selector XCEIVE 5000, decoder CX23887, demodulator ZL10353). I tried to switch on it in Linux, but it seems it's not supported (cx23885 driver says board: UNKNOWN/GENERIC). But I've read that's not that very difficult to add necessary information about it to get it work, but I never read a detailed instructions how to do it. Could you please tell me what should I do to get it supported? I'm C++ programmer myself but not familiar with Linux kernel very much. So any detailed instruction where to add necessary structures would be great. I also can gather information about the card (GPIO etc.) if it should be added by kernel maintainers only. Thank you in advance.
