Data Structure Documentation

ethosu_driver

struct ethosu_driver

Driver handle.

Caller-allocated driver handle. Initialize it to zero before first use and do not modify its members.

ethosu_driver_version

struct ethosu_driver_version

Driver version.

This structure holds Ethos-U driver implementation version:

struct ethosu_driver_version
{
  uint8_t major;
  uint8_t minor;
  uint8_t patch;
};

ethosu_job

struct ethosu_job

Driver job state.

Internal job state. Applications must not modify it.

ethosu_id

struct ethosu_id

Hardware Identification Information.

This structure holds hardware ID:

struct ethosu_id
{
  uint32_t version_status; ///< Version status
  uint32_t version_minor;  ///< Version minor
  uint32_t version_major;  ///< Version major
  uint32_t product_major;  ///< Product major
  uint32_t arch_patch_rev; ///< Architecture version patch
  uint32_t arch_minor_rev; ///< Architecture version minor
  uint32_t arch_major_rev; ///< Architecture version major
};

Data Fields
uint32_t	version_status	Version status.
uint32_t	version_minor	Version minor.
uint32_t	version_major	Version major.
uint32_t	product_major	Product major.
uint32_t	arch_patch_rev	Architecture version patch.
uint32_t	arch_minor_rev	Architecture version minor.
uint32_t	arch_major_rev	Architecture version major.

ethosu_config

struct ethosu_config

Hardware Configuration Information.

This structure holds configuration information:

struct ethosu_config
{
  uint32_t macs_per_cc;        ///< MACs per clock cycle
  uint32_t cmd_stream_version; ///< NPU command stream version
  uint32_t custom_dma;         ///< Custom DMA enabled
};

The macs_per_cc member contains the encoded hardware field, not the literal number of MACs. The number of MACs per clock cycle is (1U << macs_per_cc).

Data Fields
uint32_t	macs_per_cc	MACs per clock cycle.
uint32_t	cmd_stream_version	NPU command stream version.
uint32_t	custom_dma	Custom DMA enabled.

ethosu_hw_info

struct ethosu_hw_info

Hardware Information.

This structure holds Ethos-U hardware information:

struct ethosu_hw_info
{
  struct ethosu_id version;
  struct ethosu_config cfg;
};

ethosu_pmu_ops

struct ethosu_pmu_ops

Variant-specific PMU operations.

Internal operation table selected for the NPU family associated with a driver instance.

ethosu_pmu_desc

struct ethosu_pmu_desc

Variant-specific PMU descriptor.

Associates a driver instance with its PMU operation table.

ethosu_device_ops

struct ethosu_device_ops

Variant-specific device operations.

Internal operation table implemented by each Ethos-U family backend.

ethosu_device_caps

struct ethosu_device_caps

NPU product capabilities.

Identifies the Ethos-U product, its encoded MAC configuration, and optional feature bits.

ethosu_device

struct ethosu_device

Device state owned by a driver instance.

Holds the selected backend, register base, capabilities, configuration, and optional per-driver user operations. Applications must not modify it.

ethosu_device_config

struct ethosu_device_config

Variant-specific device configuration wrapper.

Points to the configuration structure expected by the selected device backend.
