Protection domain mapper is a QMI service providing mapping between 'protection domains' and services supported / allowed in these domains. For example such mapping is required for loading of the WiFi firmware or for properly starting up the UCSI / altmode / battery manager support. The existing userspace implementation has several issue. It doesn't play well with CONFIG_EXTRA_FIRMWARE, it doesn't reread the JSON files if the firmware location is changed (or if the firmware was not available at the time pd-mapper was started but the corresponding directory is mounted later), etc. However this configuration is largely static and common between different platforms. Provide in-kernel service implementing static per-platform data. NOTE: this is an RFC / RFC, the domain mapping data might be inaccurate (especially for SM6xxx and SC7xxx platforms), which is reflected by several TODO and FIXME comments in the code. Changes since RFC v1: - Swapped num_domains / domains (Konrad) - Fixed an issue with battery not working on sc8280xp - Added missing configuration for QCS404 Dmitry Baryshkov (5): soc: qcom: add pd-mapper implementation remoteproc: qcom: pas: correct data indentation remoteproc: qcom: adsp: add configuration for in-kernel pdm remoteproc: qcom: mss: add configuration for in-kernel pdm remoteproc: qcom: pas: add configuration for in-kernel pdm drivers/remoteproc/Kconfig | 3 + drivers/remoteproc/qcom_q6v5_adsp.c | 67 +++++ drivers/remoteproc/qcom_q6v5_mss.c | 84 ++++++ drivers/remoteproc/qcom_q6v5_pas.c | 418 +++++++++++++++++++++++----- drivers/soc/qcom/Kconfig | 10 + drivers/soc/qcom/Makefile | 2 + drivers/soc/qcom/qcom_pdm.c | 302 ++++++++++++++++++++ drivers/soc/qcom/qcom_pdm_msg.c | 189 +++++++++++++ drivers/soc/qcom/qcom_pdm_msg.h | 66 +++++ include/linux/soc/qcom/pd_mapper.h | 35 +++ 10 files changed, 1108 insertions(+), 68 deletions(-) create mode 100644 drivers/soc/qcom/qcom_pdm.c create mode 100644 drivers/soc/qcom/qcom_pdm_msg.c create mode 100644 drivers/soc/qcom/qcom_pdm_msg.h create mode 100644 include/linux/soc/qcom/pd_mapper.h -- 2.39.2 --- Dmitry Baryshkov (5): soc: qcom: add pd-mapper implementation remoteproc: qcom: pas: correct data indentation remoteproc: qcom: adsp: add configuration for in-kernel pdm remoteproc: qcom: mss: add configuration for in-kernel pdm remoteproc: qcom: pas: add configuration for in-kernel pdm drivers/remoteproc/Kconfig | 3 + drivers/remoteproc/qcom_q6v5_adsp.c | 87 ++++++- drivers/remoteproc/qcom_q6v5_mss.c | 84 +++++++ drivers/remoteproc/qcom_q6v5_pas.c | 483 ++++++++++++++++++++++++++++++------ drivers/soc/qcom/Kconfig | 10 + drivers/soc/qcom/Makefile | 2 + drivers/soc/qcom/qcom_pdm.c | 300 ++++++++++++++++++++++ drivers/soc/qcom/qcom_pdm_msg.c | 188 ++++++++++++++ drivers/soc/qcom/qcom_pdm_msg.h | 66 +++++ include/linux/soc/qcom/pd_mapper.h | 35 +++ 10 files changed, 1176 insertions(+), 82 deletions(-) --- base-commit: 20af1ca418d2c0b11bc2a1fe8c0c88f67bcc2a7e change-id: 20240301-qcom-pd-mapper-e12d622d4ad0 Best regards,
