	Result of a device lookup. More...

Functions
constexpr auto	arch::s390x::css::devmatch::class_name (dev_class cls) noexcept -> std::string_view
	Get a human-readable name for a device class.
constexpr auto	arch::s390x::css::devmatch::cu_class_of (u16 cu_type) noexcept -> dev_class
	Get the device class for a control-unit type.
constexpr auto	arch::s390x::css::devmatch::device_class_of (u16 dev_type) noexcept -> dev_class
	Get the device class for a device type.
constexpr auto	arch::s390x::css::devmatch::lookup_cu (u16 cu_type) noexcept -> std::string_view
	Look up a control-unit type by its IBM 4-digit code.
constexpr auto	arch::s390x::css::devmatch::lookup_device (u16 dev_type) noexcept -> std::string_view
