ASoC: SOF: amd: set ipc flags to zero

2026-06-09T17:30:40+00:00

As per design, set IPC conf structure flags to zero during acp init sequence. Link: https://github.com/thesofproject/linux/pull/5642 Signed-off-by: Vijendar Mukunda Tested-by: Umang Jain Link: https://patch.msgid.link/20260609160938.3717513-2-Vijendar.Mukunda@amd.com Signed-off-by: Mark Brown

ASoC: SOF: amd: fix for ipc flags check

2026-06-09T17:30:39+00:00

Firmware will set dsp_ack to 1 when firmware sends response for the IPC command issued by host. Similarly dsp_msg flag will be updated to 1. During ACP D0 entry, the value read from the sof_dsp_ack_write scratch flag can be uninitialized. A non-zero garbage value is treated as a pending DSP IPC ack before SOF_FW_BOOT_COMPLETE, causing a spurious "IPC reply before FW_BOOT_COMPLETE" log. Fix the condition checks for ipc flags.

ASoC: SOF: amd: Fix error code handling in psp_send_cmd()

2026-05-12T01:14:33+00:00

The smn_read_register() helper returns negative error codes on failure or the register value on success. When used with read_poll_timeout(), the return value is stored in the 'data' variable. Currently 'data' is declared as u32, which causes negative error codes to be cast to large positive values. This makes the condition 'data > 0' incorrectly treat errors as success. Fix by changing 'data' from u32 to int, matching the pattern used in psp_mbox_ready() which correctly handles the same helper function.

ASoC: SOF: Intel: add an empty adr_link

ASoC: SOF: Don't allow pointer operations on unconfigured streams

2026-04-10T12:57:09+00:00

When reporting the pointer for a compressed stream we report the current I/O frame position by dividing the position by the number of channels multiplied by the number of container bytes. These values default to 0 and are only configured as part of setting the stream parameters so this allows a divide by zero to be configured. Validate that they are non zero, returning an error if not Fixes: c1a731c71359 ("ASoC: SOF: compress: Add support for computing timestamps") Cc: stable@vger.kernel.org Link: https://patch.msgid.link/20260326-asoc-compress-tstamp-params-v1-1-3dc735b3d599@kernel.org Signed-off-by: Mark Brown

ASoC: SOF: Intel: hda: modify period size constraints for ACE4

2026-04-08T12:15:40+00:00

Intel ACE4 based products set more strict constraints on HDA BDLE start address and length alignment. Add a constraint to align period size to 128 bytes. The commit removes the "minimum as per HDA spec" comment. This comment was misleading as spec actually does allow a 2 byte BDLE length, and more importantly, period size also directly impacts how the BDLE start addresses are aligned, so it is not sufficient just to consider allowed buffer length.
