Current definitions are missing 12 and 64 kHz, have typos (11250, 22500), list a weird 40kHz and don't have extension capabilities for non-standard rates Before we create ABI problems with the Linux kernel, let's add all the sampling frequencies needed before we submit stuff upstream (the same list needs to be reflected in the kernel include/uapi) Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> --- src/include/uapi/ipc.h | 32 ++++++++++++++++++-------------- 1 file changed, 18 insertions(+), 14 deletions(-) diff --git a/src/include/uapi/ipc.h b/src/include/uapi/ipc.h index c820118..733d8e5 100644 --- a/src/include/uapi/ipc.h +++ b/src/include/uapi/ipc.h @@ -302,20 +302,24 @@ enum sof_ipc_chmap { }; /* common sample rates for use in masks */ -#define SOF_RATE_8000 (1 << 0) -#define SOF_RATE_11250 (1 << 1) -#define SOF_RATE_16000 (1 << 2) -#define SOF_RATE_22500 (1 << 3) -#define SOF_RATE_24000 (1 << 4) -#define SOF_RATE_32000 (1 << 5) -#define SOF_RATE_40000 (1 << 6) -#define SOF_RATE_44100 (1 << 7) -#define SOF_RATE_48000 (1 << 8) -#define SOF_RATE_88200 (1 << 9) -#define SOF_RATE_96000 (1 << 10) -#define SOF_RATE_176400 (1 << 11) -#define SOF_RATE_192000 (1 << 12) - +#define SOF_RATE_8000 (1 << 0) /* 8000Hz */ +#define SOF_RATE_11025 (1 << 1) /* 11025Hz */ +#define SOF_RATE_12000 (1 << 2) /* 12000Hz */ +#define SOF_RATE_16000 (1 << 3) /* 16000Hz */ +#define SOF_RATE_22050 (1 << 4) /* 22050Hz */ +#define SOF_RATE_24000 (1 << 5) /* 24000Hz */ +#define SOF_RATE_32000 (1 << 6) /* 32000Hz */ +#define SOF_RATE_44100 (1 << 7) /* 44100Hz */ +#define SOF_RATE_48000 (1 << 8) /* 48000Hz */ +#define SOF_RATE_64000 (1 << 9) /* 64000Hz */ +#define SOF_RATE_88200 (1 << 10) /* 88200Hz */ +#define SOF_RATE_96000 (1 << 11) /* 96000Hz */ +#define SOF_RATE_176400 (1 << 12) /* 176400Hz */ +#define SOF_RATE_192000 (1 << 13) /* 192000Hz */ + +/* continuous and non-standard rates for flexibility */ +#define SOF_RATE_CONTINUOUS (1 << 30) /* range */ +#define SOF_RATE_KNOT (1 << 31) /* non-continuous */ /* stream PCM frame format */ enum sof_ipc_frame { -- 2.9.3
