Intel Stratix10 FPGA manager, which is 1st service layer client, is included in this submission. Service layer patches have been reviewed internally by Alan Tull and other colleagues at Intel. Intel Stratix10 SoC is composed of a 64 bit quad-core ARM Cortex A53 hard processor system (HPS) and Secure Device Manager (SDM). SDM is the hardware which does the FPGA configuration, QSPI, Crypto and warm reset. In order to configure the FPGA from HPS, there needs to be a way for HPS to notify SDM the location and size of the configuration data. Then SDM will get the configuration data from that location and perform the FPGA configuration. To meet the whole system security needs and support virtual machine requesting communication with SDM, only the secure world of software (EL3, Exception Level 3) can interface with SDM. All software entities running on other exception levels must channel through the EL3 software whenever it needs service from SDM. Intel Stratix10 service layer driver is added to provide the service for FPGA configuration. Running at privileged exception level (EL1, Exception Level 1), Intel Stratix10 service layer driver interfaces with the service provider at EL1 (Intel Stratix10 FPGA Manager) and manages secure monitor call (SMC) to communicate with secure monitor software at secure monitor exception level (EL3). Later the Intel Stratix10 service layer driver will be extended to provide services for QSPI, Crypto and warm reset. v2: add patches for FPGA manager, FPGA manager binding, dts and defconfig remove intel-service subdirectory and intel-service.h, move intel-smc.h and intel-service.c to driver/misc subdirectory remove global variables change service layer driver be 'default n' correct SPDX markers add timeout for do..while() loop add kernel-doc for the functions and structs, correct multiline comments replace kfifo_in/kfifo_out with kfifo_in_spinlocked/kfifo_out_spinlocked rename struct intel_svc_data (at client header) to intel_svc_client_msg rename struct intel_svc_private_mem to intel_svc_data other corrections/changes from Intel internal code reviews v3: change all exported functions with "intel_svc_" as the prefix Increase timeout values for claiming back submitted buffer(s) Rename struct intel_command_reconfig_payload to struct intel_svc_command_reconfig_payload Add pr_err() to provide the error return value change to put fpga_mgr node under firmware/svc node change to FPGA manager to align the update of service client APIs, and the update of fpga_mgr device node Other corrections/changes Alan Tull (3): dt-bindings: fpga: add Stratix10 SoC FPGA manager binding arm64: dts: stratix10: add fpga manager and region fpga: add intel stratix10 soc fpga manager driver Richard Gong (4): dt-bindings, firmware: add Intel Stratix10 service layer binding arm64: dts: stratix10: add service driver binding to base dtsi driver, misc: add Intel Stratix10 service layer driver defconfig: enable fpga and service layer .../bindings/firmware/intel,stratix10-svc.txt | 57 ++ .../bindings/fpga/intel-stratix10-soc-fpga-mgr.txt | 17 + arch/arm64/boot/dts/altera/socfpga_stratix10.dtsi | 34 + arch/arm64/configs/defconfig | 5 + drivers/fpga/Kconfig | 6 + drivers/fpga/Makefile | 1 + drivers/fpga/stratix10-soc.c | 534 ++++++++++++ drivers/misc/Kconfig | 12 + drivers/misc/Makefile | 1 + drivers/misc/intel-service.c | 962 +++++++++++++++++++++ drivers/misc/intel-smc.h | 205 +++++ include/linux/intel-service-client.h | 188 ++++ 12 files changed, 2022 insertions(+) create mode 100644 Documentation/devicetree/bindings/firmware/intel,stratix10-svc.txt create mode 100644 Documentation/devicetree/bindings/fpga/intel-stratix10-soc-fpga-mgr.txt create mode 100644 drivers/fpga/stratix10-soc.c create mode 100644 drivers/misc/intel-service.c create mode 100644 drivers/misc/intel-smc.h create mode 100644 include/linux/intel-service-client.h -- 2.7.4
