11 daysRemove malloc call from device init codeHEADmainJonny Svärd
As there is max one device per driver handle, store the device struct in the driver struct and get rid of the malloc call from the device init code. Change-Id: I0f98a78907cb322d98278e9adc314e3c05f54308 Signed-off-by: Jonny Svärd <jonny.svaerd@arm.com>

Make sure that pmu_event_value returns a valid PMU event value before writing to PMU HW registers. Change-Id: I546493a7870fc73ef2b7269cd4d7be4072c3cebf Signed-off-by: Jonny Svärd <jonny.svaerd@arm.com>

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

2021-11-01Autumn clean/refactor of NPU driverJonny Svärd
A continuation of the spring clean/refactor work. Create a better separation between driver and device(s). A short summary of what this commit contains: - Split device and driver - Simplify and hide the internal device interface - Remove (broken) abort inference functionality - Refactoring of structure - Optimizations and bugfixes Change-Id: I8988bc5f163f9ea62add2a933e4f100a82cc8d35
2021-07-08Improved Logging - Core Driver logging clean up21.08-rc321.08-rc221.08-rc121.08Anton Moberg
Made a separate header file for logging specific content. Cleaned up logging messages. Change-Id: Id329b40977156ca5b954b3a222effaedbc6b2a2c
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
2021-04-12Clock 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
2021-01-27MLBEDSW-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

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).

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
