15 model features for SME is included in Appendix A.
24 * The presence of SME is reported to userspace via HWCAP2_SME in the aux vector
25 AT_HWCAP2 entry. Presence of this flag implies the presence of the SME
27 described in this document. SME is reported in /proc/cpuinfo as "sme".
34 * Support for the execution of SME instructions in userspace can also be
36 instruction, and checking that the value of the SME field is nonzero. [3]
