2023-12-19Support timeout for interrupt semaphore24.02-rc124.02Jonny Svärd
Introduce ETHOSU_INFERENCE_TIMEOUT CMake variable to set an arbitrary timeout value that will be sent as argument to ethosu_semaphore_take() for the interrupt semaphore. Adding the ability to have a timeout for an inference. (Defaults to no timeout/wait forever.) Implement a placeholder mutex for the baremetal example and add error checks for mutex_create() call.

2022-11-14Update header file documentation22.11-rc222.11Kristofer Jonsson
Update documentation in driver header file. Some functions were inconsistently returning boolean status. These functions have been updated to return integer status, with 0 on success and negative error code on failure. Change-Id: Ie044bf5b4f2daaff348e698fa6147472dbc582a9
2022-11-14Remapping command stream and base pointersKristofer Jonsson
Add new weak function ethosu_address_remap() that allows the addresses for QBASE and BASEP to be remapped. Change-Id: I36b0d71c57bfd293672b10c7b85f3b2415e9c839
2022-10-03Reading QREAD and STATUS register22.11-rc1Kristofer Jonsson
Allow the QREAD and STATUS registers to be read using the PMU interface. Change-Id: I7e349a0938404011588c1d5eb82b4a5dbc7c27e4
2022-05-05Refactor power handling22.05-rc1Jonny Svärd
Add reference counted ethosu_request_power(), ethosu_release_power() functions. While there are active requests, disable the Q-channel power gating of the Ethos-U device, leaving the device powered on. Note that clock gating is implemented to follow the state of the power gating. Add ethosu_soft_reset() function. Restore power- and clock gating state after reset. Refactor and simplify driver code to use the new functions. Change-Id: I9756572c5c3e51b2be244bcea856d88e890e2d40
2022-04-20Change mutex and semaphore handling weak functions prototypeLedion Daja
Changed mutex lock/unlock and semaphore take/give functions to return an int value instead of void. Change-Id: I619327b9e14a3c37697617cbe0cba358102bd6a0
2022-03-31Add driver async APIJonny Svärd
Add an asynchronous API to the driver. The current synchronous API is now using the new async API internally. The main new functions are ethosu_invoke_async() and ethosu_wait(). Every successfull call to ethosu_invoke_async() must be followed by a call to ethosu_wait() to get the status of the inference. The wait function can be called in a blocking or non-blocking mode by specifying the `block` argument to true/false. The regular synchronous invoke function is implemented as a invoke_async followed by a wait(block=true) call. Short sommary of changes: - Add an internal ethosu_job struct to keep track of inference data and job state. - Use async API in blocking mode for normal flow - Change default semaphore implementation to binary type - Move error prints out of interrupt context - Move ethosu_inference_begin() callback to right before HW invoke - Always call ethosu_inference_end() callback, even in case of errors - On NPU error, do not keep NPU powered after being reset Change-Id: If4c3c46e3c6732a669e17251bd848dea5765a490
2022-01-28Inference begin and end user argumentKristofer Jonsson

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
2021-05-03[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
2021-04-13MLBEDSW-4301 - Verification check custom_dmaAnton Moberg

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

2021-03-16Use 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
2021-02-19MLBEDSW-3868 - Driver multiNPU lockingAnton Moberg

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

2020-07-02Move PMU functions from pmu_ethosu.h to ethosu_pmu.cBhavik Patel
This change is done as a prerequisite to be able to set base address for NPU through ethosu_init(). So instead of using a mamory mapped struct we use the same functions to read/write PMU registers as the rest of the ethos-u driver. Change-Id: Ie1f6e6af4627cbe9375e2b2d079ba8017b6294d3
