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
2021-03-19Make IRQ handler weakKristofer Jonsson
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

* Allow driver to run cmdstreams that are compiled for older arch versions Change-Id: Ia49fc6c34b118bd91ce24bd0c34d95abc4c25d6a Signed-off-by: Douglas Troha <douglas.troha@arm.com>
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

2020-12-02Remove CPU build flags from driverDaniel Anderberg
Using a cpu without proper interrupt handling is not really usefull in this context, so remove that option. Change-Id: Ie94fd9025c918eef72272e14ad5b0a95ea7dc4a4

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
2020-11-20Add API to set secure and privilege level of NPU20.11-rc2Per Åstrand
Change-Id: I8ca309ea4e5885865d5c9cf848500f45f83e08a2
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. Change-Id: I175644ef37bee62cc77d789d2b7bc3073e72ea5a
2020-11-10Fast memory error handling20.11-rc1Kristofer Jonsson

2020-10-23Incorrect PMU cycle counterKristofer Jonsson
The low and high PMU cycle counter registers were not combined correctly. Change-Id: I6b311b33527557f459fd87ebd5d4d3228625106a
2020-10-20PMU counter shadowKristofer Jonsson
Storing PMU counters in shadow variables, in case the PMU was powered off or soft reset. Change-Id: I64ccf3fb6195f9be2d8315891ec612bb75404885
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
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). Change-Id: Id81799e2ac43a83b998541ce7531d2039202cd62
2020-09-28Don't use NULL for integer variablesPer Åstrand
Avoid using NULL to initialize and compare with for integer variables. Change-Id: I1c370a9bb213dc93db845149d123915273411551
2020-09-28Avoid casting to integer of different sizePer Åstrand
Avoid casting pointers to integer types larger than the pointer itself, and let assignement handle the conversion. Change-Id: Icfd2401617f2cd0fc96c2a6a9ad8d2d8bec94c55

2020-09-28Use inttypes format specifiers for logging valuesPer Åstrand
GCC and armclang uses different uint32_t types which makes it impossible to use standard format specifiers to satisfy both compilers. Move to inttypes.h macros to handle it in a portable way. Change-Id: If85e1148d302b64660af66d8f462efba9ac5d86b

2020-08-24Base pointer offset and soft resetKristofer Jonsson
Allow user to define a base pointer offset, if the CPU and the NPU have address spaces offseted from each other. Soft reset NPU before every inference. Added log prints. Change-Id: I98a746d20dc780fefa23ad68816f5ba2ba2e6c6e

2020-07-22MLBEDSW-2594 Initialize the Ethos-U before every jobBhavik Patel
This includes resetting the Ethos-U and restoring the previosuly saved PMU configuration (if any). Change-Id: Id952fb6fef513468952b6a469e857510f8c0214c
2020-07-17MLBEDSW-2596 Add support to set driver log severityBhavik Patel
The driver can log at one of the following levels: 0=emerg, 1=alert, 2=crit, 3=err, 4=warning, 5=notice, 6=info, 7=debug. The logs at or below the set level are printed whereas the higher level logs are not printed. Change-Id: I05a498d4c8c78112207187d9dceaa2386b138c5d
2020-07-03MLBEDSW-2378 Set NPU base address in ethosu_initBhavik Patel
Change-Id: I1145834000ff81d6e497a8fa77bf997478a80372
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

2020-06-26MLBEDSW-2447 Set clock_q_enable & power_q_enable correctlyBhavik Patel
Bit [2] in CMD register is used to enable clock off using clock q-interface and enable the master clock gate. Bit [3] is used to enable power off using power q-interface. The clock_q_enable bit is set when putting the Ethos-U into run state. The power_q_enable bit is set to 0 when running the command stream and set to 1 after command stream has finished running.

2020-06-12Move command stream and base address alignment checksBhavik Patel
Moving the alignment checks for command stream and base addresses to handle_command_stream(). This is done so that applications which directly call ethosu_run_command_stream(), and don't have command stream & base addresses properly aligned can still run the command stream. Change-Id: Ie02e9952af027e3017e53ea7217698a33a33b418
2020-06-05MLBEDSW-2272 Reenable the version checker for optimizer configBhavik Patel
Also check that the command stream address and base address are aligned to 16 bytes. Return error in case they are not correctly aligned. Change-Id: I786d03f403d02d601ee74c53d2dede85b2b0e8a0
2020-06-02Rework AXI patch to not depend on CMakeJonny Svärd
Make ethosu_config.h define default macro's (with default values) unless the user overrides them. For CMake users, the macros can be defined on cmd line by specifying CMAKE_C_FLAGS for cmake, like: cmake ... -DCMAKE_C_FLAGS='-DFOO=1 -DBAR=2' Change-Id: I20fd3e07fdcfb7cba58da7198fd986f8821902bb
