ASoC: SOF: Intel: Use generic names for IPC types

2023-09-19T12:49:11+00:00

Use the new SOF_IPC_TYPE_3, SOF_IPC_TYPE_4 in core code.

No functional changes, just renaming.

ASoC: SOF: Intel: hda-loader: Add support for split library loading

2023-09-15T12:15:33+00:00

There is a certain sequence needs to be followed when configuring the HDA
DMA in host and DSP.
The firmware provides a way to handle this two stage sequencing by
splitting the library loading into two stage:
1st stage: LOAD_LIBRARY_PREPARE message
           the lib_id is 0, used to configure the DMA on DSP side
2nd stage: LOAD_LIBRARY message
           both dma_id and lib_id is valid, used for the actual transfer of
           the library

In case a firmware without support for this two stage loading is used then
the second stage message will trigger the loading and the first stage will
return with error, which is ignored by the kernel.

ASoC: SOF: Use no_reply calls for TX

2023-04-20T11:51:45+00:00

Convert all existing calls that pass "NULL, 0" for reply data to the new
no_reply calls. Also convert any calls that pass in data but don't
actually parse the result.

ASoC: SOF: Intel: hda-loader: use small buffer for iccmax stream

2022-11-07T13:58:24+00:00

The data received via iccmax stream is not used anywhere, so no need to
allocate a big DMA buffer for it. This is especially important as the
allocation is done even in cases where reload of the firmware is skipped
and execution happens directly from the firmware stored in IMR.

ASoC: SOF: Intel: hda-stream: rename CL_SD_CTL registers as SD_CTL

2022-10-26T13:18:06+00:00

The use of the CL prefix is misleading. HDaudio streams are used for
code loading since ApolloLake, but they are also used for regular
audio transfers.

No functionality change, pure rename.

ASoC: SOF: Intel: Add ipc4 library loading implementation

2022-10-21T12:05:07+00:00

On Intel HDA platforms the library loading is done via DMA and an IPC
message is also need to be sent to initiate the downloading of the new
library.

ASoC: SOF: Intel: hda: Add flag to indicate that the firmware is IMR booted

2022-10-21T12:05:06+00:00

Dynamic loading of external libraries should not be done if the firmware
was booted from IMR since in that case the libraries will be restored along
with the basefw.

The booted_from_imr flag is introduced and set to true if the IMR boot was
successful and to false if cold booting is executed.

The reason for the new flag is that guessing from existing flags, used to
decide if we should try booting from IMR or not is not going to be robust
as the IMR boot itself can fail and in that case a full, cold boot is
executed.
