zx_system_get_features

SUMMARY

Get supported hardware capabilities.

DECLARATION

#include <zircon/syscalls.h>

zx_status_t zx_system_get_features(uint32_t kind, uint32_t* features);

DESCRIPTION

zx_system_get_features() populates features with a bit mask of hardware-specific features. kind indicates the specific type of features to retrieve, e.g. ZX_FEATURE_KIND_CPU. The supported kinds and the meaning of individual feature bits is hardware-dependent. ZX_FEATURE_KIND_VM is not hardware-dependent and returns a bitset currently the only meaningful bit is ZX_VM_FEATURE_CAN_MAP_XOM which is 1 if the system can map pages with execute only permission.

RIGHTS

TODO(fxbug.dev/32253)

RETURN VALUE

zx_system_get_features() returns ZX_OK on success.

ERRORS

ZX_ERR_NOT_SUPPORTED The requested feature kind is not available on this platform.

NOTES

Refer to Install Fuchsia on a device for supported processor architectures.

Refer to zircon/features.h for kinds of features and individual feature bits.
