[Sound-open-firmware] [RESEND v6 0/1] firmware: mtk: add adsp ipc protocol for sof
by Allen-KH Cheng 18 Mar '22

18 Mar '22

This patch provides mtk adsp ipc support for sof. ADSP IPC protocol offers (send/recv) interfaces using mediatek-mailbox APIs. This was tested and confirmed on MT8195 cherry board with sof. Based on linux-next changes since v5: - fix WARNING: modpost: missing MODULE_LICENSE() in drivers/mailbox /mtk-adsp-mailbox.o. Add MODULE_LICENSE in the last line. - Due to WARNING: Missing or malformed SPDX-License-Identifier tag in line 1 in checkpatch, we don't remove SPDX-License in line 1. changes since v4: - add error message for wrong mbox chan changes since v3: - rebase on v5.16-rc8 - update reviewers changes since v2: - add out tag for two memory free phases changes since v1: - add comments for mtk_adsp_ipc_send and mtk_adsp_ipc_recv - remove useless MODULE_LICENSE - change label name to out_free Allen-KH Cheng (1): firmware: mediatek: add adsp ipc protocol interface drivers/firmware/Kconfig | 1 + drivers/firmware/Makefile | 1 + drivers/firmware/mediatek/Kconfig | 9 + drivers/firmware/mediatek/Makefile | 2 + drivers/firmware/mediatek/mtk-adsp-ipc.c | 161 ++++++++++++++++++ .../linux/firmware/mediatek/mtk-adsp-ipc.h | 65 +++++++ 6 files changed, 239 insertions(+) create mode 100644 drivers/firmware/mediatek/Kconfig create mode 100644 drivers/firmware/mediatek/Makefile create mode 100644 drivers/firmware/mediatek/mtk-adsp-ipc.c create mode 100644 include/linux/firmware/mediatek/mtk-adsp-ipc.h -- 2.18.0

[Sound-open-firmware] [PATCH v18 0/2] mtk: add ADSP mailbox controller for MT8195
by Allen-KH Cheng 04 Mar '22

Mediatek ADSP IPC is used to send notification or short message between processors with dsp. It will place the message to the share buffer and will access the ADSP mailbox registers to kick dsp. Two mailboxes used to send notification or short message between processors with dsp. This patchset was tested and confirmed on MT8195 cherry board. Based on tag: next-20220223, linux-next/master changes since v17: - remove description and add maxItems for reg and interrupts in mtk,adsp-mbox.yaml changes since v16: - fix WARNING: modpost: missing MODULE_LICENSE() in drivers/mailbox /mtk-adsp-mailbox.o.

[Sound-open-firmware] New, separate sof-tplg-v1.2.3.tar.gz tarball release for topologies
by Herbert, Marc 23 Feb '22

23 Feb '22

Hi, Topologies tend to require more frequent releases, so we plan to split future sof binary releases into two different tarballs instead of one. From: sof-bin-v1.2.3.tar.gz # firmare _and_ topologies in the same tarball To: sof-bin-v1.2.4.tar.gz # firmware sof-tplg-v1.2.4.tar.gz # topologies Every firmware tarball will have a corresponding topologies tarball. Some topologies releases will have NO corresponding firmware tarball. At this point in time there is no plan to change the structure of the sof-bin git repo, this change will affect tarballs only. Thoughts, comments? Thanks! Marc https://github.com/thesofproject/sof-bin/releases

[Sound-open-firmware] [PATCH v2] ASoC: SOF: Intel: Add topology overwrite for Felwinter
by Brent Lu 21 Feb '22

21 Feb '22

From: Ajye Huang <ajye_huang(a)compal.corp-partner.google.com> The Felwinter uses four max98360a amplifiers on corresponding CH0~CH3. There are four amps on the board connecting to headphone to SSP0 port, amp to SSP1,and the DAI format would be DSP_A,8-slots, 32 bit slot-width.
