Re: midi problem, an isa device on a pci card
Hello,
I've recived no responses. Anyway, the following includes my
own solution to the question, lots of trial and error. I've found that
isahints was the closest exsting code to what I wanted.
As always, I would love to hear any comments.
How do I create isa devices from a pci device. Do I search up the
soundcard tree for the pci bus then search down for the isa bus, then
create_child(...mpushim)?
In pci device_attach:
isa=devclass_find(isa);
if( !isa ) {
device_printf(sc-dev,cmi midi error no devclass for isa\n);
goto err;
}
if (devclass_get_devices(isa, isalistp, isacountp) != 0 ) {
device_printf(sc-dev,cmi midi error fetching isa devices\n);
goto err;
}
if ( isacountp 1 ) {
device_printf(sc-dev,cmi midi no isa busses found\n);
goto err;
}
/*
* Be stupid and just pick the first isa bus
*/
sc-isadev = isalistp[0];
mpuisa=devclass_find(mpuisa);
if( !mpuisa ) {
device_printf(sc-dev,cmi: midi driver not found\n);
goto err;
}
i = devclass_find_free_unit(mpuisa,0);
sc-mpudev = BUS_ADD_CHILD(sc-isadev, 1, mpuisa, i);
[Needs to be done with BUS_ADD_CHILD, I tried with others, m' yo
they just don't work]
How do I tell the shim before the probe/attach what io region to look
at, do I fiddle with ivars (or some internal structure), do I mess with hints
via kenv(9) [Is there a kenv(9)? ]
[ Say, p-port=0x300, then following would set it to 0x300-0x302
and the same IRQ as the pci device ]
bus_set_resource(sc-mpudev, SYS_RES_IOPORT, 0, p-port, 2);
bus_set_resource(sc-mpudev, SYS_RES_IRQ, 0, rman_get_start(sc-irq), 1);
if( device_probe_and_attach(sc-mpudev) == 0 ) {
device_printf(sc-dev,added %s/%s\n,
device_get_nameunit(sc-isadev),
device_get_nameunit(sc-mpudev) );
return ;
}
Cheers,

Re: MIDI
I'm interrested in using MIDI on FreeBSD, too, but I have to tell you, that - as far as I found out - there has been midi support some time ago, but it's not included in the system/kernel anymore. There's probably some hope although, I don't find it, but I remember someone stated that you can easily apply the netbsd midi code as a patch to the current kernel. 5.0RC2 works according to this source, but had system reboots, when kldloading the midi module. If you're interrested, maybee you have more luck searching, there aren't many articles about freebsd and midi on the net (especially newer ones). I'll keep on searching Friedemann Hello, I am not sure if this is most appropriate here, but there is no sound-dev-current mailing list. I was very happy when compiling my 5.0 kernel.

Newpcm is what, five years old? Whatever it is, it ain't new anymore. Of course, maybe I'm completely mistaken about the whole situation and all newpcm needs is a boost. you are completely mistaken. first, let me correct some of the factual inaccuracies that you are propounding: * newpcm is not even 4 years old yet. * alsa is in no way desireable- it is not a device abstraction system. every app must do userland resampling to play, say 44.1khz sound on a 48khz only chipset. given that it does not provide hardware abstraction, alsa's kernel components are far too complex. * alsa drivers are difficult to write- compare one to its corresponding newpcm driver. * newpcm has a much more advanced architecture than alsa, and is entirely different than oss. the fact that newpcm's dsp and mixer layers implement the oss api is incidental. newpcm v2, which may gain a better name, is under development. i originally hoped to have it ready for 5.0, but very poor health over the last year prevented this. instead, it will be targetted at 6.0 and probably backported to ~5.3+ once feature complete and demonstrably stable. i will not elaborate here on the features planned for v2, but replacing the api is one of them, although oss compatibility will be provided. there are a few people out there who know the plans, but they all know that i want them kept under wraps for now. with only two main developers, you should not expect v2 to be committed much before the end of this year. additional manpower would help, but don't volunteer if i'm going to have to spend time teaching you c, the kernel, kobj or the current design of newpcm. someone well versed in dsp techniques and acquainted with the mathematics of accoustics would be very helpful. money and/or hardware would be nice, but i at least am limited in speed by my body and nothing short of a few million dollars is likely to change that. the single greatest incentive to continue that the community could provide is to refrain from suggesting that newpcm be scrapped or replaced, especially by proponents who are not willing to do the code themselves, do not have a replacement working prior to their proposal, and/or have little to zero knowledge of sound hardware and the requirements of a top-flight audio infrastructure.

On and off, as far as I can tell. If you want MIDI right now, take a look at what 4Front Technologies offers in their commercial OSS package. Hello Micheal and all, (this is reply targeted at the thread) In not sure about 4front compatability with -current. ALSA would require a complete rewrite to work for multiple platforms because they are intimate with the linux pci interface. IMHO, it would require a fork of their project. MIDI in FreeBSD is highly hackable. It took me only a couple of days to get midi working for an es173x, a made a small web page a few months ago, it was for 5.0-dp2 but would probably work with 5.0-R. As it is, midi can be a kld and all that is required for a particular card is basic IO. The emu10k should be easier than most because we already have code for a generic mpu401. Here are some web links, http://www.cnd.mcgill.ca/~mat/es137xmidi.html (my small es137x midi page, mostly derived from other sources) Nice references for midi hacking: from NetBSD (it's .se.netbsd because .netbsd seems to be down) http://cvsweb.se.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/dev/midi.c http://cvsweb.se.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/dev/midisyn.c http://cvsweb.se.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/dev/sequencer.c http://cvsweb.se.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/dev/pci/esa.c http://cvsweb.se.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/dev/pci/emuxki.c (oops, no midi for emu on netbsd) from ALSA: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/alsa/alsa-kernel/drivers/mpu401/ http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/alsa/alsa-kernel/pci/ http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/alsa/alsa-kernel/pci/emu10k1/ After all of this, the reality is, very few people care about midi for freebsd and it has been neglected for along time. We're lucky that the work done long ago still works. --Mat -- Brain: Pinky, are you pondering what I'm pondering? Pinky: I think so Brain, but pants with horizontal stripes make me look chubby.

Re: midi causes panic on boot? (update)
Hello folks, I have tried it with today's -CURRENT, and as soon as I try to boot a kernel with the options (this has occured also earlier but wanted to make sure that I try today's sources first) device midi device seq (my sound card is a ISAPnP SB 64 AWE) I use device sbc too. the kernel still panics with Fatal Trap 12. I have Seigo Tanimura's fixes, and yet this still happens. I do not have a serial console, so here a short trace output transcribed: _mtx_lock_sleep mpu_uartmode mpu_attach mprobe_attach device_probe_and_attach bus_generic_attach sbc_attach device_probe_and_attach isa_probe_children configure mi_startup() begin() At the point of panic not even the swap partition is available yet so the machine does not dump. How can I force it? I would like to offer any and all help to anyone wanting to debug this; I can reproduce the problem at will and luckily no FS corruption occurs because the panic is so early on boot.:-) Of course, as soon as I omit the midi part, the kernel boots fine, and the sound card works too. -- Regards: Szilveszter ADAM Szeged University Szeged Hungary To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Hello folks,
I have tried it with today's -CURRENT, and as soon as I try to boot a
kernel with the options (this has occured also earlier but wanted to make
sure that I try today's sources first)
device midi
device seq
(my sound card is a ISAPnP SB 64 AWE)
I use device sbc too.
the kernel still panics with Fatal Trap 12. I have Seigo Tanimura's
fixes, and yet this still happens. I do not have a serial console, so here
a short trace output transcribed:
_mtx_lock_sleep
mpu_uartmode
mpu_attach
mprobe_attach
device_probe_and_attach
bus_generic_attach
sbc_attach
device_probe_and_attach
isa_probe_children
configure
mi_startup()
begin()
At the point of panic not even the swap partition is available yet so the
machine does not dump. How can I force it?
I would like to offer any and all help to anyone wanting to debug this; I
can reproduce the problem at will and luckily no FS corruption occurs
because the panic is so early on boot.:-)
Of course, as soon as I omit the midi part, the kernel boots fine, and the
sound card works too.
