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 / RFT, 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. -- 2.39.2 --- Changes in RFC v3: - Send start / stop notifications when PD-mapper domain list is changed - Reworked the way PD-mapper treats protection domains, register all of them in a single batch - Added SC7180 domains configuration based on TCL Book 14 GO - Link to v2: https://lore.kernel.org/r/20240301-qcom-pd-mapper-v2-0-5d12a081d9d1@xxxxxxxxxx Changes in RFC v2: - Swapped num_domains / domains (Konrad) - Fixed an issue with battery not working on sc8280xp - Added missing configuration for QCS404 --- Dmitry Baryshkov (7): soc: qcom: pdr: protect locator_addr with the main mutex soc: qcom: qmi: add a way to remove running service 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 | 82 +++++- drivers/remoteproc/qcom_q6v5_mss.c | 80 +++++- drivers/remoteproc/qcom_q6v5_pas.c | 546 ++++++++++++++++++++++++++++++------ drivers/soc/qcom/Kconfig | 10 + drivers/soc/qcom/Makefile | 2 + drivers/soc/qcom/pdr_interface.c | 6 +- drivers/soc/qcom/qcom_pdm.c | 346 +++++++++++++++++++++++ drivers/soc/qcom/qcom_pdm_msg.c | 188 +++++++++++++ drivers/soc/qcom/qcom_pdm_msg.h | 66 +++++ drivers/soc/qcom/qmi_interface.c | 67 +++++ include/linux/soc/qcom/pd_mapper.h | 39 +++ include/linux/soc/qcom/qmi.h | 2 + 13 files changed, 1348 insertions(+), 89 deletions(-) --- base-commit: 67908bf6954b7635d33760ff6dfc189fc26ccc89 change-id: 20240301-qcom-pd-mapper-e12d622d4ad0 Best regards, -- Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>
