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
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
Modifying mutex and semaphore APIs allowing the driver to create any number of mutexes and semaphores. Using semaphore when waiting for interrupt. Making irq_triggered a member of the driver struct. Change-Id: Ib0645c9c7c0c029795269ac4b18e6ec29159d0f8
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
Added: Weak linked symbols for locking if RTOS overrides Added: Semaphore Producer (release a reserved driver) Added: Semaphore Consumer (all drivers reserved and waiting for returned driver) Added: Mutex protect thread sensitive driver access Added: Weak linked symbols for yielding & resuming thread/task while waiting for IRQ Added: static inline function of ethosu_invoke_v2(...) for backwards compatibility Change-Id: If415a73b01b2357b31bb6da86f3038344c4245c6
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
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

2020-11-24Restore default init values as init_v2Per Åstrand
The addition of init_v3 accidentely changed default values for soft resetting Ethos-U. Restore the default parameters to non-secure, user mode for init_v1 and init_v2 and also make sure to check return value from ethosu_soft_reset. Change-Id: If7377f11ad1db7ff988fdcba03320a54e6e0c0c1

2020-10-16MLBEDSW-3094 Improve soft reset of ETHOSU when running jobsBhavik Patel
The ETHOSU is soft-reset only if the previous job failed or if the current privilege level is not user or if the current security level is not secure. Change-Id: Id10b96058d67805d179ac693537606d55e10379b

This includes resetting the Ethos-U and restoring the previosuly saved PMU configuration (if any). Change-Id: Id952fb6fef513468952b6a469e857510f8c0214c
2020-07-03MLBEDSW-2378 Set NPU base address in ethosu_initBhavik Patel

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
