11 included in SME.
13 This document does not aim to describe the SME architecture or programmer's
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]
42 * There are a number of optional SME features, presence of these is reported

H A Dvmcoreinfo.rst389 AMD-specific with SME support: it indicates the secure memory encryption
391 encrypted. If SME is enabled in the first kernel, the crash kernel's
393 mask. This is used to remove the SME mask and obtain the true physical
397 additional SME-relevant info can be placed in that variable.
