The SOF core is responsible for\nserializing the IPC messages to the DSP from the different clients.\nOne example of an SOF client would be an IPC test client that\nfloods the DSP with test IPC messages to validate if the\nserialization works as expected. Multi-client support will also add\nthe ability to split the existing audio cards into multiple ones,\nso as to e.g. to deal with HDMI with a dedicated client instead of\nadding HDMI to all cards.\n\nRanjani Sridharan (3):\n ASoC: SOF: Introduce descriptors for SOF client\n ASoC: SOF: Create client driver for IPC test\n ASoC: SOF: ops: Add new op for client registration\n\n sound/soc/sof/Kconfig | 30 +++\n sound/soc/sof/Makefile | 6 +-\n sound/soc/sof/core.c | 10 +\n sound/soc/sof/intel/Kconfig | 1 +\n sound/soc/sof/intel/apl.c | 25 +++\n sound/soc/sof/intel/bdw.c | 25 +++\n sound/soc/sof/intel/byt.c | 28 +++\n sound/soc/sof/intel/cnl.c | 25 +++\n sound/soc/sof/ops.h | 34 +++\n sound/soc/sof/sof-client.c | 91 ++++++++\n sound/soc/sof/sof-client.h | 84 +++++++\n sound/soc/sof/sof-ipc-test-client.c | 325 ++++++++++++++++++++++++++++\n sound/soc/sof/sof-priv.h | 9 +\n 13 files changed, 692 insertions(+), 1 deletion(-)\n create mode 100644 sound/soc/sof/sof-client.c\n create mode 100644 sound/soc/sof/sof-client.h\n create mode 100644 sound/soc/sof/sof-ipc-test-client.c" }
