* Remove all audio format conversion code from the kernel (btw holdingratchov2015-05-111-115/+7
| | | | | | | | | the kernel_lock), as we already do better conversions in user-mode. Yet, no need for every single driver to fiddle with the conversion code as they are done transparently by common MI code. With help from armani and miod, support from mpi ok armani@

* Add a DVACT_WAKEUP op to the *_activate() API. This is called after thederaadt2013-12-061-7/+3
| | | | | | | | kernel resumes normal (non-cold, able to run processes, etc) operation. Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people
* Since audio code is mp safe, establish isa and pci audio interruptsratchov2013-05-241-3/+3
| | | | | | | | with the IPL_MPSAFE flag. In certain circumstances, this prevents interrupt handlers from waiting the global kernel_lock possibly (hold by slower code) to be released. ok kettenis
* Introduce a global interrupt-aware mutex protecting dataratchov2013-05-151-12/+14
| | | | | | | | | | | | | 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
* Remove config_activate() and DVACT_ACTIVATE. PCMCIA's the only thingmatthew2011-07-031-3/+1
| | | | | | | | that's ever used it, and it's long since been changed to use DVACT_{QUIESCE,SUSPEND,RESUME} instead. ok deraadt@, dlg@; miod@ also agreed with this idea when I brought it up a few weeks ago

* add two new members to structs audio_encoding and audio_prinfo.jakemsr2010-07-151-1/+8
| | | | | | | | | | 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

* 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.
* 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.
