* many changes:Cameron Grant2001-08-238-27/+27
| | | | | | | | | | | | | | | | | | * add new channels to the end of the list so channels used in order of addition * de-globalise definition of struct snddev_info and provide accessor functions where necessary. * move the $FreeBSD$ tag in each .c file into a macro and allow the /dev/sndstat handler to display these when set to maximum verbosity to aid debugging. * allow each device to register its own sndstat handler to reduce the amount of groping sndstat must do in foreign structs.

* Use INTR_TYPE_AV for the interrupt handlers because:Peter Wemm2001-06-164-4/+4
| | | | | | | | | | | | 1: most drivers are sensitive to timing, and 2: the handlers are MPSAFE and need a chance to get into the kernel before some other non-mpsafe handler blocks the ithread on Giant in shared irq cases. Reviewed by: cg (in principle) Notes: svn path=/head/; revision=78366
* use a global devclass for all drivers - i'm not entirely sure why thisCameron Grant2001-06-166-12/+0
| | | | | | | | | | | | | | | | | | worked before. mixer, dsp and sndstat are seperate devices - give them their own cdevsws instead of demuxing requests sent to a single cdevsw. use the si_drv1/si_drv2 fields in dev_t structures for holding information specific to an open instance of mixer/dsp. nuke /dev/{dsp,dspW,audio}[0-9]* links - this functionality is now provided using cloning. various locking fixes.

* Move out the files from src/sys/isa/ic/ to src/sys/dev/ic/, so theyJoerg Wunsch2001-06-042-2/+2
| | | | | | | | | | | | | can be made userland-visible as <dev/ic/...>. Also, those files are not supposed to contain any bus-specific details at all, so placing them under .../isa/ has been a misnomer from the beginning. The files in src/sys/dev/ic/ have been repo-copied from their old location (this commit is a forced null commit there to record this message). Notes: svn path=/head/; revision=77726

* mega-commit.Cameron Grant2001-03-248-139/+344
| | | | | | | | | | | | | | | | | | this introduces a new buffering mechanism which results in dramatic simplification of the channel manager. as several structures have changed, we take the opportunity to move their definitions into the source files where they are used, make them private and de-typedef them. the sound drivers are updated to use snd_setup_intr instead of bus_setup_intr, and to comply with the de-typedefed structures. the ac97, mixer and channel layers have been updated with finegrained locking, as have some drivers- not all though. the rest will follow soon. Notes: svn path=/head/; revision=74763

| | | | | | | | | | | | both should work in non-pnp mode, the 924 should also work in its rather braindead pnp mode- it will adopt port 0x530 unless given hints due to it starting up in soundblaster mode and thus not requesting a valid mss port address.

* - Mutexify midi(4). The driver runs under the giant lock by default.Seigo Tanimura2001-02-265-349/+285
| | | | | | | | | | | | | | | | | If you ever want to run midi(4) out of the giant lock, uncomment MIDI_OUTOFGIANT in midi.h. Confirmed to work for csamidi with WITNESS and INVARIANTS. - midi_info, midi_open and seq_info are now tailqs, allowing arbitrary numbers of devices to be configured. - Do not send an active sensing message to reset midi modules. - Clone /dev/sequencer*. /dev/sequencer0 and /dev/sequencer are generated upon initialization.

| | | | | | | | | | | | | | | | | | | | | cloning infrastructure standard in kern_conf. Modules are now the same with or without devfs support. If you need to detect if devfs is present, in modules or elsewhere, check the integer variable "devfs_present". This happily removes an ugly hack from kern/vfs_conf.c. This forces a rename of the eventhandler and the standard clone helper function. Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include like <sys/queue.h> Remove all #includes of opt_devfs.h they no longer matter. Notes: svn path=/head/; revision=65374
