ASoC: SOF: ipc: replace "enum sof_comp_type" field with "uint32_t"

2024-08-26T18:29:39+00:00

Normally, the type of enums is "unsigned int" or "int". GCC has the "-fshort-enums" option, which instructs the compiler to use the smallest data type that can hold all the values in the enum (i.e: char, short, int or their unsigned variants). According to the GCC documentation, "-fshort-enums" may be default on some targets. This seems to be the case for SOF when built for a certain 32-bit ARM platform. On Linux, this is not the case (tested with "aarch64-linux-gnu-gcc") which means enums such as "enum sof_comp_type" will end up having different sizes on Linux and SOF. Since "enum sof_comp_type" is used in IPC-related structures such as "struct sof_ipc_comp", this means the fields of the structures will end up being placed at different offsets. This, in turn, leads to SOF not being able to properly interpret data passed from Linux. With this in mind, replace "enum sof_comp_type" from "struct sof_ipc_comp" with "uint32_t".

ASoC: SOF: uapi: header: Update sof_abi_hdr doc for IPC4 use

2023-03-13T14:06:51+00:00

With IPC4 the sof_abit_hdr is only used between user space (and in topology) and kernel. The same abi header is used with small differencies like different magic number and the type field have slightly different name, but similar function in IPC4 (param_id). Update the kernel documentation to highlight the differences.

Add new field to sof_ipc_stream_params in order to extend stream params struct with extended data to store compress parameters. Older kernel will still work this as they ext_data_length will always be zero.

ASoC: SOF: ipc: introduce cont_update_posn in sof_ipc_stream_params struct

2022-05-10T13:01:54+00:00

The host stream position is updated when no_stream_position is set as 0. However current implementation updates host stream position only when report data is larger than or equal to host period size which is decided by the period size of host side. It maybe cause host stream position update not in time. Therefore this patch introduces another field "cont_update_posn", a boolean value aimed to update host stream position continuously and based on period size of pipeline. It can get better precise when need to update host stream position from firmware.
