1 Using XSTATE features in user space applications
6 evaluate which features have been enabled by the kernel XCR0.
8 Up to AVX-512 and PKRU states, these features are automatically enabled by
9 the kernel if available. Features like AMX TILE_DATA (XSTATE component 18)
14 The purpose for dynamic features
25 size of 2KB with existing applications is too small for new CPU features
30 Using dynamically enabled XSTATE features in user space applications
34 request the usage of such features. The arch_prctl(2) options related to
39 arch_prctl(ARCH_GET_XCOMP_SUPP, &features);
41 ARCH_GET_XCOMP_SUPP stores the supported features in userspace storage of
46 arch_prctl(ARCH_GET_XCOMP_PERM, &features);
48 ARCH_GET_XCOMP_PERM stores the features for which the userspace process
70 for the permitted features.

138 Dynamic features in signal frames
141 Dynamically enabled features are not written to the signal frame upon signal
143 non-dynamic features which are always written regardless of their
145 field to determine if a features was written.
