This proposal builds on the existing Intel solution and the experience gathered over two years with Meego and Android solutions. This proposal is no longer Intel-specific and was generalized with the addition of a basic core; codec-related definitions are based on the vendor-neutral OpenMAX AL standard. These patches are also available in git tree: git://git.infradead.org/users/vkoul/snd-compress.git v3_patches Changes in v3: Fixed the device registration for compressed devices as discussed moved card creation to lower level drivers Added new api for device node creation changes fragment/frame callbacks to single inlined callback Changes in v2: Fixed the comments revived in v2 Fixed the comments recieved during LPC discussions add support for alsa device registeration fix the bugs found in testing Omair Mohammed Abdullah (1): core: add support for compressed devices Pierre-Louis Bossart (1): compress API documentation Vinod Koul (4): core: add compress parameter definations core: add API header and driver header files core: add support for compress_offload core: add makefile and kconfig file for compress Documentation/sound/alsa/snd_compress_data.txt | 184 +++++++ include/sound/compress_driver.h | 164 ++++++ include/sound/compress_offload.h | 151 +++++ include/sound/core.h | 1 + include/sound/minors.h | 7 +- include/sound/snd_compress_params.h | 395 +++++++++++++ sound/core/Kconfig | 8 + sound/core/Makefile | 4 + sound/core/compress_offload.c | 701 ++++++++++++++++++++++++ sound/core/sound.c | 6 + 10 files changed, 1620 insertions(+), 1 deletions(-) create mode 100644 Documentation/sound/alsa/snd_compress_data.txt create mode 100644 include/sound/compress_driver.h create mode 100644 include/sound/compress_offload.h create mode 100644 include/sound/snd_compress_params.h create mode 100644 sound/core/compress_offload.c
