MFC r265359 and r265780:

2014-05-23T06:28:31Z

Remove ISA load dependency for the kernel sound driver module for ARM and MIPS.

MFC r266006 and r266011:

2014-05-21T06:29:52Z

Fix unload of USB audio kernel module.

r260607: The onyx codec works also as module, so add it. r260610: Described in the man page but not implemented. Here it comes, atomic_swap_32/64. The latter only for powerpc64. r260934: Fix the resource information for the i2s-a node on certain G5 PowerMacs. This is the first step needed to get the snapper codec working on those machines. The second step is to enable the corresponding I2S device and its clock. Tested on machines where the snapper codec was already working, a G4 PowerBook and a PowerMac9,1 with a Shasta based macio. The PowerMac7,2/7,3 with a K2 based macio can now also play sound.

Clean some 'svn:executable' properties in the tree.

Add driver for the RME HDSPe AIO/RayDAT sound cards -- snd_hdspe(4).

2012-03-01T13:10:18Z

Cards are expensive and so rare, so leave the driver as module. Submitted by: Ruslan Bukin MFC after: 2 weeks

Add MK_SOURCELESS build option. Setting MK_SOURCELESS to "no" will disable

kernel modules that include binary-only code. More fine-grained control is provided via MK_SOURCELESS_HOST (for native code that runs on host CPU) and MK_SOURCELESS_UCODE (for microcode). Reviewed by: julian, delphij, freebsd-arch Approved by: kib (mentor) MFC after: 2 weeks

Replace GPLd headers from the Maestro3 driver with BSD licensed

2012-01-20T22:37:10Z

versions derived from /usr/ports/audio/oss. The particular headers used were taken from the attic/drv/oss_allegro directory and are mostly identical to the previous files. The Maestro3 driver is now free from the GPL. NOTE: due to lack of testers this driver is being considered for deprecation and removal. PR: kern/153920 Approved by: jhb (mentor) MFC after: 2 weeks

Major snd_hda driver rewrite:

2012-01-15T13:21:36Z

- Huge old hdac driver was split into three independent pieces: HDA controller driver (hdac), HDA CODEC driver (hdacc) and HDA sudio function driver (hdaa). - Support for multichannel recording was added. Now, as specification defines, driver checks input associations for pins with sequence numbers 14 and 15, and if found (usually) -- works as before, mixing signals together. If it doesn't, it configures input association as multichannel. - Signal tracer was improved to look for cases where several DACs/ADCs in CODEC can work with the same audio signal. If such case found, driver registers additional playback/record stream (channel) for the pcm device. - New controller streams reservation mechanism was implemented. That allows to have more pcm devices then streams supported by the controller (usually 4 in each direction). Now it limits only number of simultaneously transferred audio streams, that is rarely reachable and properly reported if happens. - Codec pins and GPIO signals configuration was exported via set of writable sysctls. Another sysctl dev.hdaa.X.reconfig allows to trigger driver reconfiguration in run-time. - Driver now decodes pins location and connector type names. In some cases it allows to hint user where on the system case connectors, related to the pcm device, are located. Number of channels supported by pcm device, reported now (if it is not 2), should also make search easier. - Added workaround for digital mic on some Asus laptops/netbooks.
