ctl_clear_bit()

template<u32 Reg>

auto arch::s390x::cpu::ctlreg::ctl_clear_bit ( const u32 bit ) ->void

exportnoexcept

Clear a single bit (IBM MSB numbering) in a control register.

Template Parameters

Reg	Control register index (0–15).

Parameters

bit	Bit number in IBM MSB-0 notation.

ctl_load()

template<u32 Low, u32 High, typename T>
requires (Low <= 15 && High <= 15 && Low <= High && sizeof(T) >= (High - Low + 1) * 8)

auto arch::s390x::cpu::ctlreg::ctl_load ( const T & storage ) ->void

exportnoexcept

Load control registers [Low..High] from a storage area (LCTLG).

Template Parameters

Low	Starting control register index (0–15).
High	Ending control register index (0–15), must be ≥ Low.
T	Storage type; sizeof(T) must cover (High-Low+1) × 8 bytes.

Parameters

storage

Input buffer containing the new register values.

ctl_set_bit()

template<u32 Reg>

auto arch::s390x::cpu::ctlreg::ctl_set_bit ( const u32 bit ) ->void

exportnoexcept

Set a single bit (IBM MSB numbering) in a control register.

Template Parameters

Reg	Control register index (0–15).

Parameters

bit	Bit number in IBM MSB-0 notation (bit 0 = MSB of the 64-bit register).

ctl_store()

template<u32 Low, u32 High, typename T>
requires (Low <= 15 && High <= 15 && Low <= High && sizeof(T) >= (High - Low + 1) * 8)

auto arch::s390x::cpu::ctlreg::ctl_store ( T & storage ) ->void

exportnoexcept

Store control registers [Low..High] into a storage area (STCTG).

Template Parameters

Low	Starting control register index (0–15).
High	Ending control register index (0–15), must be ≥ Low.
T	Storage type; sizeof(T) must cover (High-Low+1) × 8 bytes.

Parameters

storage

Output buffer to receive the register values.
