* Remove all audio format conversion code from the kernel (btw holdingratchov2015-05-111-29/+3

* Replace all queue *_END macro calls except CIRCLEQ_END with NULL.doug2014-09-131-3/+3
| | | | | | | | CIRCLEQ_* is deprecated and not called in the tree. The other queue types have *_END macros which were added for symmetry with CIRCLEQ_END. They are defined as NULL. There's no reason to keep the other *_END macro calls. ok millert@

* Since audio code is mp safe, establish isa and pci audio interruptsratchov2013-05-241-3/+3

* Introduce a global interrupt-aware mutex protecting dataratchov2013-05-151-15/+41
| | | | | | | | | | | | | structures (including sound-card registers) from concurent access by syscall and interrupt code-paths. Since critical sections remain the same, calls to splraise/spllower can be safely replaced by calls to mtx_enter/mtx_leave with two exceptions: (1) mutexes are not reentrant (the inner splraise is thus removed), and (2) we're not allowed to sleep with a mutex (either msleep is used or the mutex is released before sleeping). ok and help from kettenis, a lot of work from armani

* add two new members to structs audio_encoding and audio_prinfo.jakemsr2010-07-151-9/+12
| | | | | | | | | | for both structs, the new members are 'bps' and 'msb', which describe the number of bytes per sample and data alignment in the sample, respectively. drivers must properly set these fields in the 'query_encoding', 'set_parameters' and 'get_default_params' hardware interface methods. discussed with ratchov, deraadt

* audio(9) says low level drivers are allowed to change the requestedjakemsr2008-10-251-4/+3
| | | | | | | | | | | | | | values of the audio_params structure during AUDIO_SETINFO if the hardware cannot be set to exactly the requested mode. some drivers do this sometimes. others always return EINVAL if there isn't an exact match. be more consistent. only return EINVAL if an absurd parameter was requested, otherwise return a supported set of parameters, as close as possible to what was requested. with/ok ratchov@
* use ac97 default parameters for these ac97 based drivers.jakemsr2008-05-291-2/+9
| | | | | | | | | | | this makes the emulation expansion factor 1 by default since there's no emulation. previously the factor was 2 because these drivers emulate 8-bit ulaw playback with 16-bit linear encodings. having a factor other than 1 by default creates block size and hiwat/lowat issues with applications that set the block size and hiwat before other parameters. ok ratchov@
* allow low level audio drivers to specify a default sample format,jakemsr2008-04-211-2/+3
| | | | | | | | | instead of 8-bit mono mulaw @ 8kHz. this is just the infrastructure; no drivers are specifying a default yet. ok ratchov@, deanna@

| | | | | | | | "busy state" in which it's not writeable. This fix tags the host as unable to read the codec, so the ac97 driver doesn't try to read it, instead it keeps in memory copy of all codec registers. Fixes pr 2451 ok jakemsr

* Stereo jitter suppressor.espie2001-09-051-3/+22
| | | | | | | | Idea from FreeBSD. This code was not put in initially because I had no problematic card to test. Thanks to Chris Kuethe <ckuethe@pyxis.cns.ualberta.ca> for having such a card and testing this code.
* Change pci_intr_map to take pci_attach_args as an argument.art2001-08-251-3/+2
| | | | | | | | | | | All callers actually took all arguments to pci_intr_map from pci_attach_args structs, so this simplifies code. This also allows more complicated interrupt assignment schemes like the one on sparc64. This makes sparc64 pci interrupts work. Inspired by the same change in NetBSD.
* fix mmap.espie2001-08-021-2/+5
| | | | | | Add workaround for uvm brain-deadness (allow open O_RDWR, which is necessary for mmap to work, since mmap(PROT_WRITE) does NOT work on devices)
* Make pci_mapreg_map take an extra argument where we canniklas2001-06-121-2/+2
| | | | | | | put a size limitation of the PCI region to map. That makes the PERC 3/Di raid controller usable, as it publishes too much PCI memory for us to map in the kernel virtual memory. As we only access the first 256 byte it is of no use to map 128MB of kvm.

the FreeBSD driver, and some linux code. Probably some tweaks to reach out for more pci cards (some models are currently commented out, and we have yet to find a card where stereo output gets de-synchronized, as the FreeBSD driver claims happens). Suspends/resume works, recording and keyboard volume control on the way. This is not derived from the NetBSD driver in any way. Just happens that both works reached completion at the same time.
