I do not know, that is the reason why I'm asking here.
This sample can have disabled AES-NI by vendor, in BIOS, for example. As I show by links this is posible. CPUID in you example don't show AES-NI capabilities, for example 1650v4 w/ AES-NI CPU: Intel(R) Xeon(R) CPU E5-1650 v4 @ 3.60GHz (3600.07-MHz K8-class CPU) Origin="GenuineIntel" Id=0x406f1 Family=0x6 Model=0x4f Stepping=1 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x7ffefbff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,SDBG,FMA,CX16,xTPR,PDCM,PCID,DCA,SSE4.1,SSE4.2,x2APIC,MOVBE,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND> ^^^^^^ AMD Features=0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> AMD Features2=0x121<LAHF,ABM,Prefetch> Structured Extended Features=0x21cbfbb<FSGSBASE,TSCADJ,BMI1,HLE,AVX2,SMEP,BMI2,ERMS,INVPCID,RTM,PQM,NFPUSG,PQE,RDSEED,ADX,SMAP,PROCTRACE> XSAVE Features=0x1<XSAVEOPT> VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID,VID,PostIntr TSC: P-state invariant, performance statistics In you sample: "TSCDLT,XSAVE" May be AES-NI disabled by vendor and FreeBSD correct show this. Or some bug in FreeBSD, AES-NI work and other OS show AES-NI capabilities. _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
