2021-06-08Spring clean/refactor of NPU driverJonny Svärd
These changes mostly focus on creating a better structure for the driver. Creating a better separation between driver and device(s). A short summary of what this commit contains: - Move driver specific defines from device to driver - Prefix device functions with ethosu_dev - Remove device specific register access' from driver - Remove device specific debug/dump functions - Add function prototypes for weak functions - Remove legacy ARM_NPU_STUB support - Rename ethosu_device.c to ethosu_device_u55.c - Remove redundant irq handler prototype - Remove (deprecated) hardcoded instance ethosu_drv - Simplify versioning API Split driver version and hardware version/information so that driver version can be queried without a driver instance. - Improve and simplify logging Make warning the new default severity level to print and reduce severity levels to: err warning info debug - Add severity prefix to log lines. Error messages print file and line number, debug messages print function by default. - Clarify some log messages - Small optimizations and bugfixes Change-Id: I2dfbfc3a40d7eca133c82f187f422325e1e6d314
2021-05-26Optimizations21.05-rc3Kristofer Jonsson
Removing the ASSERT() makro using assert() instead. assert() is better controlled with the NDEBUG define. Using uintptr_t instead of uint32_t * for the NPU base address. This saves a division by 4 in the register read and write functions. Change-Id: I65a91fe35dc63666e50bdf7a756ad15b56dc66e9

2021-01-27MLBEDSW-3796 Ethos-U driver interface multiple NPUs21.02-rc221.02-rc1Anton Moberg
---ethosu_driver--- Modified: Declarations for the driver interfaces to support multiNPU (takes *drv) Added: ethosu_register_driver(...) to allow for a specific NPU driver to be instantiated Added: ethosu_deregister_Driver(...) to allow for a specific NPU driver to be de-registered Added: ethosu_reserve_driver(...) to reserve & return the first NPU driver instance available Added: ethosu_release_driver(...) to release a specific NPU driver instance and make it available again Added: *registered_drivers - A static linked list of drivers ready be used ---ethosu_pmu--- Modified: Declarations for pmu interfaces to support multiNPU (takes *drv) ---ethosu_device--- Modified: Resolved a circular include dependency (Remove include and add ETHOSU_PMU_NCOUNTERS macro) Change-Id: Iede41cd41bb0d5d483bd9d929d1b6c9ca5d3c48e
