Detailed Description

struct drm_ethosu_dev_query - Arguments passed to DRM_ETHOSU_IOCTL_DEV_QUERY

Member Data Documentation

pointer

__u64 drm_ethosu_dev_query::pointer

@pointer: user pointer to a query type struct.

Pointer can be NULL, in which case, nothing is copied, but the actual structure size is returned. If not NULL, it must point to a location that's large enough to hold size bytes.

size

__u32 drm_ethosu_dev_query::size

@size: size of the type being queried.

If pointer is NULL, size is updated by the driver to provide the output structure size. If pointer is not NULL, the driver will only copy min(size, actual_structure_size) bytes to the pointer, and update the size accordingly. This allows us to extend query types without breaking userspace.

type

__u32 drm_ethosu_dev_query::type

@type: the query type (see drm_ethosu_dev_query_type).
