The following series introduces two components that aids in post mortem debugging of Qualcomm systems. The first part is used to store information about loaded images in IMEM, for post mortem tools to know where the kernel loaded the remoteproc firmware. The second part invokes a stop operation on the remoteprocs during a kernel panic, in order to trigger them to flush caches etc. Bjorn Andersson (8): dt-bindings: remoteproc: Add Qualcomm PIL info binding remoteproc: qcom: Introduce driver to store pil info in IMEM remoteproc: qcom: Update IMEM PIL info on load arm64: dts: qcom: qcs404: Add IMEM and PIL info region arm64: dts: qcom: sdm845: Add IMEM and PIL info region remoteproc: Introduce "panic" callback in ops remoteproc: qcom: q6v5: Add common panic handler remoteproc: qcom: Introduce panic handler for PAS and ADSP .../bindings/remoteproc/qcom,pil-info.yaml | 35 ++++ arch/arm64/boot/dts/qcom/qcs404.dtsi | 10 ++ arch/arm64/boot/dts/qcom/sdm845.dtsi | 10 ++ drivers/remoteproc/Kconfig | 6 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/qcom_pil_info.c | 150 ++++++++++++++++++ drivers/remoteproc/qcom_pil_info.h | 8 + drivers/remoteproc/qcom_q6v5.c | 19 +++ drivers/remoteproc/qcom_q6v5.h | 1 + drivers/remoteproc/qcom_q6v5_adsp.c | 27 +++- drivers/remoteproc/qcom_q6v5_mss.c | 6 + drivers/remoteproc/qcom_q6v5_pas.c | 26 ++- drivers/remoteproc/qcom_wcnss.c | 17 +- drivers/remoteproc/remoteproc_core.c | 17 ++ include/linux/remoteproc.h | 4 + 15 files changed, 328 insertions(+), 9 deletions(-) create mode 100644 Documentation/devicetree/bindings/remoteproc/qcom,pil-info.yaml create mode 100644 drivers/remoteproc/qcom_pil_info.c create mode 100644 drivers/remoteproc/qcom_pil_info.h -- 2.24.0
