arch.s390x.cpu.aste.consts Module Reference

Data Structures
struct	arch::s390x::cpu::aste::art_context
	Per-domain hardware ART state. CR2 selects duct_phys while AR-mode ALETs address ale_table_phys through DUALD at byte 16. More...

Functions
constexpr auto	arch::s390x::cpu::aste::alet_alen (u32 alet) noexcept -> u16
constexpr auto	arch::s390x::cpu::aste::alet_alesn (u32 alet) noexcept -> u8
constexpr auto	arch::s390x::cpu::aste::alet_make (u16 alen, u8 alesn) noexcept -> u32
	Build a DUCT-selected ALET for an ALE slot and sequence.

Variables
u8	_pad [8] {}
u8	ale_sequence [MAX_ALE_ENTRIES] {}
u64	ale_table_phys {0}
constexpr u32	arch::s390x::cpu::aste::ALET_ALEN_MASK = 0x0000'FFFFU
constexpr u32	arch::s390x::cpu::aste::ALET_ALESN_MASK = 0x00FF'0000U
constexpr u32	arch::s390x::cpu::aste::ALET_PRIMARY_LIST = 0x0100'0000U
constexpr u32	arch::s390x::cpu::aste::ALET_RESERVED_MASK = 0xFE00'0000U
	Hardware ALET field masks in the 32-bit register image.
constexpr u32	arch::s390x::cpu::aste::ALET_RESERVED_MAX = 2
	ALETs 0–2 are architecturally reserved (primary, secondary, home).
u64	duct_phys {0}
constexpr u32	arch::s390x::cpu::aste::MAX_ALE_ENTRIES = 16
	Maximum ALE entries in one domain's dispatchable-unit list. AR0 always selects primary space, leaving AR1-AR15 for portal ALETs.
constexpr u32	arch::s390x::cpu::aste::MAX_ASTE_ENTRIES = 256
	Maximum ASTE table entries (one per domain).
