[alsa-devel] ALSA driver for Native Instruments sound hardware
by Daniel Mack 23 Mar '08

23 Mar '08

Hi, some months after the last posting, we finally managed to finish a new version of the ALSA driver for Native Instruments' external USB sound cards such as "Rig Kontrol 2", "Kore Kontroller", "Audio Kontrol 1" and "Audio 8 DJ". Compared to the last release, the following things were changed: - the streaming logic was completely reworked so that multiple substreams are handled correctly - a Linux input device layer was added to support the knobs, buttons and pedals on "Rig Kontrol 2" and "AudioKontrol 1" - workqueues were entirely removed from the code - most data structures are now allocated within one big struct to avoid multiple, smaller allocations - many more cleanups according to Clemens' reply on my last posting[1] The driver was properly tested with all the mentioned hardware on both record and playback channels. The patchset should apply to the current mecurial alsa-kernel tree. Please let me know what you think.

[alsa-devel] Correct use of ak4114.c?
by dustin＠seznam.cz 10 Apr '07

10 Apr '07

Hello, while working on support for AK4114 in Audiotrak MI/ODI/O card, I used corresponding code from revo.c (and similarly from juli.c), calling function snd_ak4114_create. However, this function does not initialize array ak4114->kctls[idx], leading to consequent kernel oops after the periodically called snd_ak4114_check_rate_and_errors, specifically in function snd_ctl_notify called by snd_ctl_notify(ak4114->card, SNDRV_CTL_EVENT_MASK_VALUE, &ak4114->kctls[0]->id) Temporarily I resolved the problem by commenting out the snd_ctl_notify calls. However, it seems author of ak4114.c intended to create the device with snd_ak4114_build instead which defines all the controls. I did not hit the problem until fixing the 4-wire communication in revo.c - that explaing why nobody had this problem with revo cards. I do not understand how the code can work in juli.c - perhaps I have overlooked something there. My question: Is the correct way to add null pointer checks before snd_ctl_notify calls only, or to use snd_ak4114_build insted of snd_ak4114_create? If using snd_ak4114_build, where do I get the parameters ply_substream and cap_substream? int snd_ak4114_build(struct ak4114 *ak4114, struct snd_pcm_substream *playback_substream, struct snd_pcm_substream *capture_substream); Thanks for any suggestions. Pavel.

[alsa-devel] Individual PCM stream control
by Nagalla, Hari 04 Apr '07

04 Apr '07

Hello, I am new to ALSA, so some help from experienced folks would help.. We are trying to develop ALSA support for our DSP based mixer. In our architecture DSP performs the mixing, sample rate conversion etc. My question is how, can does the user space applications exercise controlling individual PCM stream to the mixer? Ex: individual stream gain control, individual stream mute, etc.. Any user space example code would be useful too.. Thanks Hari

I'm experiencing the same problem as Erik - I cannot get the ALC882 to transmit at any other sample rate than 48kHz over S/PDIF. When I attempt to play 44.1kHz sound, the S/PDIF connection is still locked at 48kHz (shown by my amplifier), and the resulting sound is less than pleasing. It would seem like a 44.1kHz signal packed in a 48kHz frame rate played back directly - high-pitched sounds suffer badly from what my ears recognize as straightforward sample picking as opposed to resampling. Looking at hda_codec.c:convert_from_spdif_status() it seems that the IEC958 parameter bit for 44.1kHz/48kHz is not used for anything (correct me if I'm wrong). This would mean that the rate is only set in snd_hda_codec_setup_stream(), and as far as I can tell from looking at the array rate_bits and the ALC882 Series Datasheet the setting is correct for 44.1kHz. Since I can't find any obvious mistake in the HDA code, I guess there is some problem in patch_realtek.c, or an initialization incompatibility with the HDA code and the ALC882 chip. There are certainly initialization problems somewhere, as the S/PDIF output is sometimes not able to send AC3 data correctly (amplifier cannot detect AC3 and stays silent), and attempting to play audio (even 48kHz) results in intermittent screeches. This is solved by setting and resetting the IEC958 control widget, trying again and again until it finally works. When it does work, it works without a hitch until the next reboot. Any ideas? Is there anything I can help to test in order to nail down the problem? My motherboard is an Asus P5W DH Deluxe with an 82801G HDA controller, in case this has any relevance. -- Best regards, Dag Lem

[alsa-devel] dereferencing pointer error in app but not in lib
by intellij 03 Apr '07

03 Apr '07

In the library, like pcm.c I can code like const char *snd_pcm_name(snd_pcm_t pcm) { return pcm->name; } At the same time, the same code in the application causes "dereferencing pointer to incomplete type" error. Note, the compiler does not tell that there is no such field in the pcm structure. It just thinks that the name has another type. Which one? thank you.

[alsa-devel] usleep() and nanosleep() timings seem inaccurate using ALSA
by Carlo Florendo 31 Mar '07

31 Mar '07

Good Day! After studying the intricacies of MIDI, I ended up writing an implementation of the MIDI protocol and file format. I then studied the ALSA sequencer API to be able to control a synthesizer keyboard and play MIDI files. I've used aplaymidi, aconnect, arecordmidi, and all those great ALSA utilities. They're very good! However, I wanted to have a simple ncurses based, command line MIDI sequencer meant for small Linux distributions such as DSL or Trustix so I began to write a command line sequencer using ALSA. I've encountered one problem about using usleep() and nanosleep() especially in 2.4 kernels. The core of my problem in my application is that the MIDI files slow down their tempo when pitch changes are made on a particular channel/track, while a NOTE-ON event is being played. For simplicity's sake, I'll give timing examples in terms of seconds and not bars nor measures. For example, if I've got a 2 second NOTE-ON playing a guitar note, all timings are ok. If the NOTE-ON is interspersed with CONTROLLER messages such as a pitch bend, the part which is supposed to sound in approximately 2 seconds, sounds much longer than that. The effect of this is that a ritardando is heard everytime short-duration CONTROLLER messages are sent. The problem disappears when I use the sequencer queues. However, the problem manifests itself when using direct output (i.e. not using queues, using snd_seq_event_output and snd_seq_drain_output one after the other). The reason why I would not want to use the queue is that I'd want the UI of my program (such as metronome ticks and counts) to somehow synch with the sound that is being heard. I've tried removing all UI elements, thinking that the UI controls might have caused the delay, but still the ritardando effect persists. The structure of my code is like this: parse_midi_file(); merge_all_tracks_to_one_single_track(); normalize_the_delta_times() for all events; do usleep(delta_time_for_each_event); play_the_event_using_alsa_direct_output(); done The ritardando effect is a bit lesser using 2.6 kernels. If I use queues, the problem disappears completely in 2.4 and 2.6 kernels. I don't hear the effect with simple MIDI files, such as with piano pieces. By the way, I intend to use my app with a 2.4 kernel. Does anybody have a solution to the delay problem? Please point out to me if I'm doing anything wrong since I've just been working with alsa-seq for a few months. Thank you very much.

[alsa-devel] 14rc3 fails to compile on vanilla 2.6.20.3
by Andrea Gozzi 30 Mar '07

Hi. I recently compiled a new kernel, 2.6.20.3, but when I tried to build alsa 14rc3 it failed. I also had troubles with the ati fglrx driver (missing declarations in headers - solved) so it could maybe be related to the new 20.x kernels. I attached logs for both the "configure" and "make". Andrea

[alsa-devel] Questions on Bluetooth Audio & Alsa Relationship
by Allyn, Mark A 30 Mar '07

30 Mar '07

Hello: Where is the correct place to discuss issues pertaining to snd-bt-sco and its relationship with Alsa? I am having trouble getting snd-bt-sco to work with Alsa 1.0.14rc3. I am getting a kernel oops for a NULL pointer somewhere in snd_bt_sco_playback_open. I looked on the blutooth-alsa sourceforge site, it seems that snd-bt-sco is no longer maintained and that they are going toward a solution using something called plugz. Plugz, however requires a kernel patch that works for kernels 2.6.19 and above, but not with 2.6.14, which is the kernel in the distro that I am using. I have attempted to ask some questions on the bluez developer email list on sourceforge, but I only got one response saying that the snd-bt-sco solution is more mature than the plugz development effort. I then asked about the kernel oops and have not got any response. What is the state of bluetooth audio development? Is it slacking off? Perhaps is the a plugz email list that I don't know about? Thank you for your help. Truly, Mark Allyn

[alsa-devel] Alsa OSS - who is maintaining it?

[alsa-devel] Function ap192_4wire_start in revo.c
by dustin＠seznam.cz 29 Mar '07

29 Mar '07

Hello, while working on support for AK4114 in Audiotrak MI/ODI/O, I have come accross a bug in revo.c (used for major inspiration :) )The function static unsigned char ap192_4wire_start(struct snd_ice1712 *ice) returns value of current GPIO bits, which is unsigned int. However, return value of the function is unsigned char. This results in clearing all GPIO8-22 in next snd_ice1712_gpio_write call of the 4-wire protocol communication which is a little bit inconvenient :). Thanks for fixing in HG. Best regards, Pavel.

You can avoid that check just for testing. If this doesn't work, the possible situation is that the SPDIF is transmitted directly from the controller chip without AC97 codec. Unfortunately, we have no hardware information about SIS7012, so don't know whether it's even possible, and how to control it. > Is there a script I need to run or file I need to update my list of > CTLs (I have seen references to alsaconf and snddev on the web but > neither seems to be included with my FC5 install of alsa-utils)? % alsactl -f somefile store > Also, is there any easy way to reload the snd-ac97-codec.ko module.

Seems that you still have the old modules on memory while installing the new modules. First unload all snd related modules, then reload again. Otherwise, something wrong with the build with your kernel tree. I never used FC or RedHat, so can't answer about it. Takashi

[alsa-devel] Enabling SPDIF output on Turtle Beach Audio Advantage Micro (CMEDIA CM102S)
by Eric Sandeen 28 Mar '07

28 Mar '07

I have this Turtle Beach Audio Advantage Micro usb sound card, er, stick. Inside it has pretty much nothing but a C-Media CM102S chip. TB claims, as does C-Media, that it can do S/PDIF out, and I believe them based on the glowing red TOSLINK light. :) I found previous emails on this list (http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg09979.html) suggesting that there is probably some magic to be applied to tell usb hardware to go into S/PDIF mode. I've captured some traces under windows, linked from http://sandeen.net/tbaam/index.html Specifically, http://sandeen.net/tbaam/2spkr-spdif.txt seems to be a fairly short burst of USB activity when I used the control panel to switch from 2 speaker mode to spdif mode. I see the exact same activity when switching from headphone mode to spdif mode. Strangely, switching from, say, spdif back to 2 speaker seems to generate a lot more traffic. The full annotated trace is here: http://sandeen.net/tbaam/usbsnoop1.txt In any case, are these traces helpful to anyone who understands how to talk to a C-Media CM102S usb sound card? Does it look possible to poke this hardware into S/PDIF mode with this information? Thanks, -Eric

[alsa-devel] New code for conexant chipsets in -mm tree

[alsa-devel] snd-es1968 capture broken
by Rene Herman 28 Mar '07

28 Mar '07

Good day. Capture is broken on snd-es1968, at least if it is driving a ES1970MS-3D (ESS Canyon 3D). The captured stream is "stuttering" like mad. Kernel 2.6.20 (ALSA 1.0.14-rc1) with alsa-lib 1.0.11 (my distribution's version). Does not happen with a CS4236 in the same machine and same software version(s). Don't know if this driver has a specific maintainer. If needed I guess I can try to pin it down to some change. I hardly use capture on this card but it wasn't always broken... Rene.

[alsa-devel] Status of CMI9738 and SiS7012
by Rob Franklin 27 Mar '07

27 Mar '07

Hi All, I posted a question a couple of weeks ago to the alsa-users list (Can't get spdif working with ALSA and FC6 on ECS L4S5MG/651+ motherboard), but never got a response. I have been looking at the ALSA source code for the AC'97 codec on my board (CMI9738) and the source code for the intel8x0 driver (for my SiS 7012). However, as far as I can tell from looking at the source, S/PDIF is not enabled/supported for this combination of devices. Additionally, Googling around I haven't found any mention of people getting spdif working with ALSA and a CM9738 / SiS7012 combo. I am wondering whether anyone on the developer list can confirm that this is the case. Also, if this is the case can someone give me an idea of what would be required to get this working. The system is setup with dual boot and so I could grab some of the values from windows using a PCI sniffer, and I might be able to do some hacking on the source code and submit a patch if someone could help guide me in the right direction. Thanks, Rob

[alsa-devel] Correct value for AK4114_DIF2 constant?
by dustin＠seznam.cz 27 Mar '07

27 Mar '07

Hello, While going through AK4114 support I have hit the constant AK4114_DIF2 in ak4114.h . I would say its value should be (1<<6) according to AK4114 datasheet. This is current situation: #define AK4114_DIF2 (1<<5) /* Audio Data Control */ #define AK4114_DIF1 (1<<5) /* Audio Data Control */ #define AK4114_DIF0 (1<<4) /* Audio Data Control */ I think cards using this code should experience related problems. E.g. in juli.c and revo.c the constant #define AK4114_DIF_I24I2S (AK4114_DIF2|AK4114_DIF1|AK4114_DIF0) /* STDO: I2S; LRCLK, BICK = Input */ is used, intended to set output serial data mode to I2S/slave perhaps compatible with ICE1712/24. This may be causing problems mentioned in revo.c: #if 0 /* FIXME: ak4114 makes the sound much lower due to some confliction, * so let's disable it right now... */ #define BUILD_AK4114_AP192 #endif I am trying to add support for SPDIF-IN of AudioTrak MI/ODI/O addon card (ice1724 + ak4114), hopefully this will be a little step forward. Thanks for any reaction. Best regards, Pavel.

[alsa-devel] capture line-out
by Tomas Carnecky 27 Mar '07

27 Mar '07

Is it possible to capture/record line-out (or simply 'what the user hears')? I'm writing 'fraps for linux' and so far I have video capturing implemented and that works great, but users are also requesting sound-capturing and I'm looking into how that could be done. thanks tom

I tried various ADPCM formats which gave correct playback speed, but much noise. There seems to be a Media Vision ADPCM format, which is probably what the Jazz16 wants, but I have no information about that format. FWIW, the playback_format/capture_format values I've tried are: #define SB_DSP_ALAW_OUTPUT_AUTO 0x1F #define SB_DSP_ALAW_INPUT_AUTO 0x2F #define SB_DSP_ULAW_OUTPUT_AUTO 0x7f #define SB_DSP_ULAW_INPUT_AUTO 0x8f #define SB_DSP_ADPCM_OUTPUT_AUTO 0x7C+1 #define SB_DSP_ADPCM_INPUT_AUTO 0x8C+1 > > Setting the irq of the MPU-401 port requires the SB part to be active and > > even worse, DSP commands need to be sent. Would it be better to just use the > > MPU-401 port without an irq and avoid the complexity? > > Isn't SB part already active? It's fine with non-irq version (which > uses timer) if the code gets too complicated, of course. It turned out that I can't disable just the MPU port. -- Rask Ingemann Lambertsen

[alsa-devel] Can't subscribe to the list
by Ed Wright 26 Mar '07

Hi, I've tried 3 times over the last week or so to subscribe to this list with no success. I can't believe I'm doing anything wrong (how hard is it?), but I don't see any posts (in the archives) indicating any problems subscribing, so I'm at a loss. Any suggestions? Or can you subscribe me manually? Thanks, Ed

[alsa-devel] ftp.alsa-project.org
by Rene Herman 26 Mar '07

26 Mar '07

Hi Jaroslav. When you currently want to download a complete new release from ftp.alsa-project.org you have to scrounge around all the directories manually. Would it be easy to automate to have a /pub/alsa/<version>/ directory containing links to all the relevant packages? Ie: /pub/alsa/1.0.13/alsa-driver-1.0.13.tar.bz2 -> ../../driver/alsa-driver-1.13.tar.bz2 and same: alsa-lib-1.0.13.tar.bz2 -> ../../lib/alsa-lib-1.13.tar.bz2 alsa-plugins-1.0.13.tar.bz2 -> ../../plugins/alsa-plugins-1.13.tar.bz2 alsa-utils-1.0.13.tar.bz2 -> ../../utils/alsa-utils-1.13.tar.bz2 alsa-tools-1.0.13.tar.bz2 -> ../../tools/alsa-tools-1.13.tar.bz2 alsa-firmware-1.0.13.tar.bz2 -> .../firmware/alsa-firmware-1.13.tar.bz2 alsa-oss-lib-1.0.12.tar.bz2 -> ../../oss-lib/alsa-oss-lib-1.12.tar.bz2 with probably links /pub/alsa/stable -> 1.0.13 and /pub/alsa/devel -> 1.14rc3 and stuff like that. (by the way, as far as I'm concerned, the /pub/alsa locations wouldn't need to be links but could just as well be the main locations but if you want to keep the current layout in place...) Would make it a bit nicer to download a new release... Rene.

[alsa-devel] hopeless about snd-hda-intel driver.
by Ustun ERGENOGLU 25 Mar '07

25 Mar '07

Hello everybody, for more than one month I have been crawling through the net to find a cure for my endless torment about ATI SB450 Realtek ALC861 soundcard. I have no problem with playback, but when it comes recording there is nothing wrong in the beginning but after sometime recording stops and I see a message about time out in dmesg output. I have made a bug report in the ALSA bug tracking system but got no response :(. It's here: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2970 Can anybody, please, tell me where to begin to solve this problem. I can even start hacking ALSA code with my next to nothing knowledge about kernel driver programming as I have more than average c programming experience. This is more than enough motivation to start some coding, I suppose. I would greatly appreciate any recommendation or help. Thanks Ustun

[alsa-devel] ALSA initialization still seems to be too late?
by Adrian Bunk 23 Mar '07

23 Mar '07

The commit below from 2005 (sic) seems to be an example that workarounds often have quite a long lifetime. Can we get this sorted out properly for 2.6.22?

Reported by Adrian Bunk <bunk(a)stusta.de> (The right fix would be to make the sound core use "subsys_initcall()" and thus initialize before all normal drivers, but this is the quick and limited safe fix for 2.6.15).

[alsa-devel] snd_pcm_writei() error: Write error: -32,Broken pipe
by John Utz 23 Mar '07

23 Mar '07

Hello; I am running into some trouble with writing out to the device, i get some sound and then i get the Write error. Heres the code fragment: if (-EAGAIN == (iErr = snd_pcm_writei(handle, pu8Frames, iSizPer))) continue; if (0 > iErr) { printf("Write error: %d,%s\n", iErr, snd_strerror(iErr)); Is the problem that my buffer (pointed to by pu8frames) isnt big enuf? or is this a different failure entirely. If so, what are the possibilities? tnx!

[alsa-devel] PCM -- no need to release params mem nor close handle?
by intellij 23 Mar '07

23 Mar '07

I am looking at PCM interface manual http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html It tells that there are an open and set_params functions but nothing about close(). Furthermore, the description of open() http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html#g8340c7dc0… neither tells that. Ok, I have realized from the examples. However, even the examples demonstrate no params deallocation. You call the snd_pcm_hw_params_alloca(&hwparams) but never release the allocated memory. Why? Thank you.

Re: [alsa-devel] Réf. : Where is _snd_pcm defined?
by intellij 23 Mar '07

23 Mar '07

Thank you for your answer. However, you information is not correct. I do not have the snd_pcm structure in the three copies of pcm.h I have in alsa-lib/include, arm-linux/alsa nor arm-linux/include. Peahaps, this is because my lib is slightly obsolete. Fortunately, today I have accidentally discovered the requested _snd_pcm structure in the alsa-lib/src/pcm/pcm_local.h. Excuse me for the fuss. BTW, we have fallen out of the mailing list. Forums are efficient only when there are many participants for two reasons: neighbors can provide more information and the same questions will be prevented from asking repeatedly. Do you think this case is different? > >Hello, > >If you get the alsa-driver sources, you can have everything you need (hope :-). >Note that in my typedefs.h, I don't have any _ at the beginin, so "struct snd_pcm" is in alsa-kernel/include/pcm.h. > >Regards, >JM > > >********************************* >This message and any attachments (the "message") are confidential and intended solely for the addressees.

[alsa-devel] Where is _snd_pcm defined?
by intellij 22 Mar '07

22 Mar '07

Hello, I have gone through all the source codes to wee the definition of snd_pcm_t and see that it is defined typedef struct _snd_pcm snd_pcm_t; But is has many fields inside! At least, name and fast_ops pointers should be there. I do not understand where are they hiding. Actually, I am an alsa user. However, the system occasionaly hangs on writing into the buffer (because the consumption stops). For this reason, I'm looking for the features for hacking the system. I have an idea of turning the printfs on/of in runtime by a shared flag. I could put the pointer to the flag into pcm, so that my application could modify it and the library functions would check it before printing the traces. Thank you.

Hi Alsa gurus, I've to write an alsa driver for a custom card. I readed "writing an alsa driver" and other paper about alsa and drivers. Well I got a result, but not as good as I think it's possible with alsa. My card have 30 output slots (and 7 input slots), can be 8Khz or 16Khz (same rate for every slots), 16bits little endian by sample, can have one or more sample for each slot (same for every slots) in a frame, an hardware IT every frame (a frame is 30 slots :-). The purpose is to get, for each IT, a frame with all the datas. IT -> frame [channel1][channel2][channel3]...[channel30] channelX [sample1][sample2]...[sampleN] sampleX [16bitsle] At this time, I've something like a frame if I use channel30 with speaker-test -c30, but if I use channel1, alsa give me a buffer with many samples for channel1. And, just after oppening, I get an extra word. BTW I use .copy to get the buffer. My questions: -why the extra word (can I avoid it?)? -how set the buffer len to always have all my channels (used or not)? -is it possible to have more than a sample by channel contiguous? Think's it's all for today, but maybe your answers will give me more ideas :-) Thanx for replies (and please, forgive my awful english :-(, JM PS: sorry for my previous (and my first) post which was in html only ********************************* This message and any attachments (the "message") are confidential and intended solely for the addressees.

Sure, what I meant is that the patch had no function to disable the libdl and libpthread explicitly but only checked. The new patch below, for example, can give you options --with-libdl and --with-pthread. For disabling libdl, pass --with-libdl=no. If this works for you, I'll apply it to the upstream.

[alsa-devel] During ADPCM playback, when is the reference byte set?
by Rask Ingemann Lambertsen 21 Mar '07

21 Mar '07

Hi. When an app is playing ADPCM samples, how does the driver know how to find the reference byte, other than assuming it is the first byte of sample data? Could there be more than one? Etc. -- Rask Ingemann Lambertsen

[alsa-devel] Problem in dummy driver
by Himanshu Chauhan 21 Mar '07

21 Mar '07

Dear all, I am working on the dummy driver provided with the ALSA. I took it from the linux kernel 2.6.20.1 I build the module and load it. The XMMS seems to play ok (doesn't hang and all) but none of the recording application seem to record from the driver. Can the driver in current state work as the loop back cable between applications? Thanks in advance... Warm Regards --Himanshu

There's also the "routed" bit though. I actually ran into this recently when I was playing with snd-sgalaxy (which is why I'm harping on it). An sgalaxy is also a (partly) software configurable card and when not given explicit parameters the driver just searches for an unrequested IRQ and DMA and then programs the card for it. Over here it grabbed IRQ 10 but then didn't work anyway, and only started working when I set IRQ 10 to "Legacy ISA" in the BIOS setup. It seems the IRQ simply was not available to ISA without having done that (no, no PCI cards were using IRQ 10 or anything). I must say though that my comment above was partly based on a somewhat foggy understanding of how things get assigned. Yes, _if_ this "routing" problem I seemed to be experiencing is not a serious problem in practice (Adam? Are you able to comment?) then the fact that the PnP layer will be handing out the resources taking into account the other (known) cards is indeed a practical advantage of using that layer. > I think there are three good reasons to use the PnP layer: > > 1) The PnP layer informs the PCI layer of irqs to try to avoid - please > see pnp_register_irq_resource() in drivers/pnp/resource.c. How does that help? On my systems (one AMI, all others Award BIOses) all PCI cards get assigned their IRQ before the OS ever boots. That "PnP OS: Yes/No" switch only effects whether or not the BIOS will fully configure all ISA-PnP cards. > 2) The PnP layer knows which resources are used by active devices, even > if they have not been allocated using e.g. request_region(). This > happens in practice. For example: Yes, this is an advantage. It does miss all the resources used by old ISA cards for which no (normal or pnp protocol as in this one) drivers have been loaded but I guess that's not much of a difference with a regular ISA driver... > 3) Knowing which resources a card can utilize, the PnP layer can try to > stay away from those resources when configuring other cards.

When I was looking at pnp/isa integration a while ago myself I was looking at it from the angle of generic old ISA (ie, hardwired non settable resources) and concluded that for these there wasn't any point. Having looked a little closer at the resource assigment being done in the PnP layer now, I now feel there's some point, but still little for those. But with software settable devices such as this Jazz16, there ofcourse is rather more point. I believe the routing issue I refferred to above is the most important thing to have answered. I also still don't really like "splitting the one driver into the two pieces" like that but well, we don't actually have all that many software settable ISA devices and I guess it's not _too_ bad to have a few of these "front-ends" run as a protocol driver at boot as long as it stays "a few". Hey, I already said I like the concept... By the way; in the "straightforward version" I posted yesterday I neglected to reserve the SB_JAZZ16_CONFIG_PORT and the SB range before poking at it during setup. Attached version corrects that. Updated patch including your SB changes still at http://members.home.nl/rene.herman/jazz16.diff Looks more involved now, but posted mainly for completeness; correcting yesterday's post. Has been tested and found working again.

A standards compliant PnPBIOS set up with "PnP aware OS = YES" will use only enough resources to boot the system, which should leave enough irqs and dmas for the Linux PnP layer to do its work. I think there are three good reasons to use the PnP layer: 1) The PnP layer informs the PCI layer of irqs to try to avoid - please see pnp_register_irq_resource() in drivers/pnp/resource.c. 2) The PnP layer knows which resources are used by active devices, even if they have not been allocated using e.g. request_region(). This happens in practice. For example: $ cat /sys/bus/pnp/devices/01\:02.00/resources state = active io 0x2a0-0x2af io 0x390-0x393 io 0x500-0x50f irq 5 dma 0 dma 1 $ cat /proc/ioports [...] 0200-0200 : ns558-pnp 0201-0201 : ns558-pnp 0208-020f : ns558-pnp 0213-0213 : ISAPnP 0280-028f : ES18xx 0356-0356 : ide2 0360-0361 : MPU401 UART 0376-0376 : 0000:00:07.1 0376-0376 : ide1 0390-0391 : OPL2/3 (left) 0392-0393 : OPL2/3 (right) 03c0-03df : vga+ 03e8-03ef : serial 03f6-03f6 : 0000:00:07.1 03f6-03f6 : ide0 03f8-03ff : serial 0500-050f : AD1816A 0800-0807 : ES18xx - CTRL [...] Notice that 0x2a0-0x2af is missing from /proc/ioports. The PnP layer will avoid using that port range because it knows a device is using it. 3) Knowing which resources a card can utilize, the PnP layer can try to stay away from those resources when configuring other cards. The PnP layer doesn't do that yet in a stock kernel, but I've patched it to do so. I'll try to get those patches into the kernel. An advantage of autoprobing in a PnP protocol driver (as opposed to doing so in a sound card driver) is that it happens before any file systems have been mounted, so if the autoprobe happens to find one of those #%!$@ NE2000 cards and lock up the system, it won't corrupt your disks. -- Rask Ingemann Lambertsen
