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.
