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
2021-05-24[Core Driver] Update and remove pmu "v2"-functionsAnton Moberg
NPU PMU interface currently have functions that have been stepped each time a compatibilty breaking changed has been introduced. Old entrypoints have been redefined with macro to use the latest version for backwards compatibility. This series of patches will remove any such functions and macro to unify the interface. Update: Remove all "_v2"-functions and make the latest version the base entrypoint Update: Remove all redefine macros to only allow base entrypoint Change-Id: Ie125e2428a0336fe797c7455014d269a981f6f92
2021-05-21Weak mutex_create returns NULLAnton Moberg

Add ethosu_inference_begin/end calls to ethosu_invoke_v3. Change-Id: I52f08ab3e3524d4d8f73d8bca7dc9559438d4857
2021-05-03[Core driver] Update to support removal of "_v"-functions21.05-rc221.05-rc1Anton Moberg
NPU driver interface currently have functions which have been stepped each time a compatibilty breaking changed has been introduced. Old entrypoints have been redefined with macro to use the latest version for backwards compatibility. This series of patches will remove any such functions and macro to unify the interface. Update: Remove all "_v"-functions and make the latest version the base entrypoint Update: Remove all redefine macros to only allow base entrypoint Note: static inline ethosu_invoke_v2() is kept as it is needed for tensorflow backwards compatibility. Will be removed in later patches. Change-Id: Ifa331daab35af24dc29e0d0007096902b8efc319

Added: custom_dma bit to config structs Added: hardware verification check for custom_dma Change-Id: I31dca56063b3ca773d02f0adf30d21facfd0b80d
2021-04-12Clock request disabled when PMU enabledAnton Moberg
Currently clock request is enabled, which means NPU will only request clock when working. When NPU is going into idle it will no longer request clock and thus PMU won't be clocked either, and thus affect the cycle counter. Added: enum for request clients (PMU or INFERENCE). Added: clock_request added to driver struct (bit 0: PMU, bit 1: INFERENCE) which keeps track of which client requests clock. Added: power_request added to driver struct (bit 0: PMU, bit 1: INFERENCE) which keeps track of which client requests power. Added set_clock_and_power_request(...) updates clock_request and power_request depending on which client calls it. Sets clock and power if both PMU and INFERENCE requests it. Added: Call set_clock_and_power_request(...) from PMU. Changed: replace ethosu_set_clock_and_power(...) with set_clock_and_power_request(...) in ethosu_init and ethosu_invoke Change-Id: Ie7d8aee639d4abbf879b05e9a82035d7c0d40d40
2021-03-23Multi NPU update APIsAnton Moberg

Allow the IRQ handler to be overridden for test cases that operate directly on top of the device driver. Change-Id: Iddf7aec041a3183583e6e4d8521d5a637c379689
2021-03-16Use event enum for configuring cycle counterPer Åstrand
The pmu configuration API expects the internal configuration values, and not the exported enum. Update the API to instead use the enums to be able to configure them correctly. Change-Id: I038b1841f2459baec4a62a6a4389ea4b5f4822f2

2021-01-18Added simplified driver setupAnton Moberg
If NPU power is guaranteed always on parts of driver setup can be omitted to reduce the number of cycles required to setup the NPU drivers. By enabling dev_power_always_on, the setup cycles are reduced by approx. ~50%. (4462->2238 in prologue, 1167->642 in epilogue) Change-Id: I56d380c2571fedbc8888fb7c00fce0e4320f7fb7

2020-11-16Flush and invalidate data cachesPer Åstrand
Implement a weak linked function to handle the data cache. If the specific device is implementing a data cache the function should be overriden with device specific implementation of the flush/invalidate functions to make sure that the cache is properly maintained with regards to the NPU DMA transaction.

2020-09-28Silence gcc > 7 type-limits warningPer Åstrand
GCC > 7 warns that the selected type of the enum makes the comparisson unneccesary. Since the selected enum fits in an integer, the input parameter is casted to an integer to make the comparison valid and asserts that the enum is within valid enum values (which we know are monotonically growing).
