ASoC: SOF: amd: add missing blank line between Kconfig entries

2026-07-07T14:06:48+00:00

Add a missing blank line between SND_SOC_SOF_AMD_ACP70 and SND_SOC_SOF_AMD_ACP7X config entries to conform to Kconfig formatting convention. Signed-off-by: Vijendar Mukunda Link: https://patch.msgid.link/20260707060918.2535962-1-Vijendar.Mukunda@amd.com Signed-off-by: Mark Brown

ASoC: SOF: amd: add system and runtime PM ops for ACP7x

2026-07-03T16:31:14+00:00

Add amd_sof_acp7x_suspend() and amd_sof_acp7x_resume() for ACP7.B/7.F platforms power management. Signed-off-by: Vijendar Mukunda Reviewed-by: Bard Liao Link: https://patch.msgid.link/20260701095759.1012929-17-Vijendar.Mukunda@amd.com Signed-off-by: Mark Brown

ASoC: SOF: amd: load ACP7.B/7.F signed data firmware to SRAM

2026-07-03T16:31:10+00:00

ACP7.B and ACP7.F signed firmware data blocks must be written to SRAM instead of DRAM. Select SOF_FW_BLK_TYPE_SRAM for PCI revision 0x7B and above in acp_sof_load_signed_firmware().

ASoC: SOF: amd: wire signed firmware load callback for ACP7x via ACPI

2026-07-03T16:31:08+00:00

Read ACPI property acp-sof-signed-firmware-image in sof_acp7x_ops_init() and register acp_sof_load_signed_firmware as the load_firmware callback only when the property is set.

ASoC: SOF: amd: extend configure_and_run_sha_dma for ACPI signed FW flag

2026-07-03T16:31:06+00:00

Check adata->acp_sof_signed_firmware_image alongside the existing quirk flag so that ACP7.B/7.F platforms configured through ACPI also get the SHA DMA header included during signed firmware loading.

ASoC: SOF: amd: add post-firmware-run delay for ACP7x

2026-07-03T16:31:04+00:00

Add sof_acp7x_post_fw_run_delay() to introduce a small delay after firmware boot completion on resume to avoid DSP entering an unrecoverable state. Register it as post_fw_run callback only when the ACPI property acp-sof-post_fw_run_delay is set, following the same pattern used by the Vangogh platform.

ASoC: SOF: amd: validate SizeFWSigned before signed FW length on ACP7x

2026-07-03T16:31:03+00:00

The ACP7.B/7.F ACPI signed path already reads SizeFWSigned from the image header into size_fw. Before adding ACP_IMAGE_HEADER_SIZE for SHA DMA, reject payload size zero or any size_fw with size_fw > fw_bin_size - ACP_IMAGE_HEADER_SIZE, so size_fw + ACP_IMAGE_HEADER_SIZE cannot exceed the supplied firmware buffer.

ASoC: SOF: amd: require full ACP header for ACP7 signed firmware

2026-07-03T16:30:55+00:00

ACP7.B/7.F signed images read SizeFWSigned from a fixed offset inside the ACP header. Reject firmware buffers shorter than the header so we never read past the end of the supplied image.

Parse SizeFWSigned from the ACP image header when loading signed firmware on ACP7.B/7.F platforms. Keep the legacy ACP_FIRMWARE_SIGNATURE subtraction for pre-7B platforms using quirks.
