}

An user state component whose size can be queried.

Support can be checked in the XCR0 register.

To access the XCR0 register use the struct StateComponentBitmap.

Variants

AVX

The state component used for the additional register state used by the Intel® Advanced Vector Extensions (AVX state).

BNDREGS_MPX

The state component used for the additional register state used by Intel® Memory Protection Extensions (MPX state) for the four 128-bit bounds registers BND0-BND3 (BNDREGS state).

BNDCSR_MPX

The state component used for the additional register state used by Intel® Memory Protection Extensions (MPX state) for the 64-bit user-mode MPX configuration register BNDCFGU and the 64-bit MPX status register BNDSTATUS (BNDSCR` state).

opmask_AVX_512

The state component used for the the additional register state used by Intel® Advanced Vector Extensions 512 (AVX-512 state) for the eight 64-bit opmask registers k0–k7 (opmask state).

ZMM_Hi256_AVX_512

The state component used for the the additional register state used by Intel® Advanced Vector Extensions 512 (AVX-512 state) the upper 256 bits of the registers ZMM0–ZMM15 (ZMM_Hi256 state).

Hi16_ZMM_AVX_512

The state component used for the the additional register state used by Intel® Advanced Vector Extensions 512 (AVX-512 state) for the sixteen 512-bit registers ZMM16–ZMM31 (Hi16_ZMM state).

PKRU

The state component used for the protection-key feature’s register PKRU (PKRU state).

See Section 13.5.7 of the Intel® 64 and IA-32 Architectures Software Developer's Manual Volume 1 (Basic Architecture).
