x86/insn: Add some Intel instructions to the opcode map
Add to the opcode map the following instructions: cldemote tpause umonitor umwait movdiri movdir64b enqcmd enqcmds encls enclu enclv pconfig wbnoinvd For information about the instructions, refer Intel SDM May 2019 (325462-070US) and Intel Architecture Instruction Set Extensions May 2019 (319433-037). The instruction decoding can be tested using the perf tools' "x86 instruction decoder - new instructions" test as folllows: $ perf test -v "new " 2>&1 | grep -i cldemote Decoded ok: 0f 1c 00 cldemote (%eax) Decoded ok: 0f 1c 05 78 56 34 12 cldemote 0x12345678 Decoded ok: 0f 1c 84 c8 78 56 34 12 cldemote 0x12345678(%eax,%ecx,8) Decoded ok: 0f 1c 00 cldemote (%rax) Decoded ok: 41 0f 1c 00 cldemote (%r8) Decoded ok: 0f 1c 04 25 78 56 34 12 cldemote 0x12345678 Decoded ok: 0f 1c 84 c8 78 56 34 12 cldemote 0x12345678(%rax,%rcx,8) Decoded ok: 41 0f 1c 84 c8 78 56 34 12 cldemote 0x12345678(%r8,%rcx,8) $ perf test -v "new " 2>&1 | grep -i tpause Decoded ok: 66 0f ae f3 tpause %ebx Decoded ok: 66 0f ae f3 tpause %ebx Decoded ok: 66 41 0f ae f0 tpause %r8d $ perf test -v "new " 2>&1 | grep -i umonitor Decoded ok: 67 f3 0f ae f0 umonitor %ax Decoded ok: f3 0f ae f0 umonitor %eax Decoded ok: 67 f3 0f ae f0 umonitor %eax Decoded ok: f3 0f ae f0 umonitor %rax Decoded ok: 67 f3 41 0f ae f0 umonitor %r8d $ perf test -v "new " 2>&1 | grep -i umwait Decoded ok: f2 0f ae f0 umwait %eax Decoded ok: f2 0f ae f0 umwait %eax Decoded ok: f2 41 0f ae f0 umwait %r8d $ perf test -v "new " 2>&1 | grep -i movdiri Decoded ok: 0f 38 f9 03 movdiri %eax,(%ebx) Decoded ok: 0f 38 f9 88 78 56 34 12 movdiri %ecx,0x12345678(%eax) Decoded ok: 48 0f 38 f9 03 movdiri %rax,(%rbx) Decoded ok: 48 0f 38 f9 88 78 56 34 12 movdiri %rcx,0x12345678(%rax) $ perf test -v "new " 2>&1 | grep -i movdir64b Decoded ok: 66 0f 38 f8 18 movdir64b (%eax),%ebx Decoded ok: 66 0f 38 f8 88 78 56 34 12 movdir64b 0x12345678(%eax),%ecx Decoded ok: 67 66 0f 38 f8 1c movdir64b (%si),%bx Decoded ok: 67 66 0f 38 f8 8c 34 12 movdir64b 0x1234(%si),%cx Decoded ok: 66 0f 38 f8 18 movdir64b (%rax),%rbx Decoded ok: 66 0f 38 f8 88 78 56 34 12 movdir64b 0x12345678(%rax),%rcx Decoded ok: 67 66 0f 38 f8 18 movdir64b (%eax),%ebx Decoded ok: 67 66 0f 38 f8 88 78 56 34 12 movdir64b 0x12345678(%eax),%ecx $ perf test -v "new " 2>&1 | grep -i enqcmd Decoded ok: f2 0f 38 f8 18 enqcmd (%eax),%ebx Decoded ok: f2 0f 38 f8 88 78 56 34 12 enqcmd 0x12345678(%eax),%ecx Decoded ok: 67 f2 0f 38 f8 1c enqcmd (%si),%bx Decoded ok: 67 f2 0f 38 f8 8c 34 12 enqcmd 0x1234(%si),%cx Decoded ok: f3 0f 38 f8 18 enqcmds (%eax),%ebx Decoded ok: f3 0f 38 f8 88 78 56 34 12 enqcmds 0x12345678(%eax),%ecx Decoded ok: 67 f3 0f 38 f8 1c enqcmds (%si),%bx Decoded ok: 67 f3 0f 38 f8 8c 34 12 enqcmds 0x1234(%si),%cx Decoded ok: f2 0f 38 f8 18 enqcmd (%rax),%rbx Decoded ok: f2 0f 38 f8 88 78 56 34 12 enqcmd 0x12345678(%rax),%rcx Decoded ok: 67 f2 0f 38 f8 18 enqcmd (%eax),%ebx Decoded ok: 67 f2 0f 38 f8 88 78 56 34 12 enqcmd 0x12345678(%eax),%ecx Decoded ok: f3 0f 38 f8 18 enqcmds (%rax),%rbx Decoded ok: f3 0f 38 f8 88 78 56 34 12 enqcmds 0x12345678(%rax),%rcx Decoded ok: 67 f3 0f 38 f8 18 enqcmds (%eax),%ebx Decoded ok: 67 f3 0f 38 f8 88 78 56 34 12 enqcmds 0x12345678(%eax),%ecx $ perf test -v "new " 2>&1 | grep -i enqcmds Decoded ok: f3 0f 38 f8 18 enqcmds (%eax),%ebx Decoded ok: f3 0f 38 f8 88 78 56 34 12 enqcmds 0x12345678(%eax),%ecx Decoded ok: 67 f3 0f 38 f8 1c enqcmds (%si),%bx Decoded ok: 67 f3 0f 38 f8 8c 34 12 enqcmds 0x1234(%si),%cx Decoded ok: f3 0f 38 f8 18 enqcmds (%rax),%rbx Decoded ok: f3 0f 38 f8 88 78 56 34 12 enqcmds 0x12345678(%rax),%rcx Decoded ok: 67 f3 0f 38 f8 18 enqcmds (%eax),%ebx Decoded ok: 67 f3 0f 38 f8 88 78 56 34 12 enqcmds 0x12345678(%eax),%ecx $ perf test -v "new " 2>&1 | grep -i encls Decoded ok: 0f 01 cf encls Decoded ok: 0f 01 cf encls $ perf test -v "new " 2>&1 | grep -i enclu Decoded ok: 0f 01 d7 enclu Decoded ok: 0f 01 d7 enclu $ perf test -v "new " 2>&1 | grep -i enclv Decoded ok: 0f 01 c0 enclv Decoded ok: 0f 01 c0 enclv $ perf test -v "new " 2>&1 | grep -i pconfig Decoded ok: 0f 01 c5 pconfig Decoded ok: 0f 01 c5 pconfig $ perf test -v "new " 2>&1 | grep -i wbnoinvd Decoded ok: f3 0f 09 wbnoinvd Decoded ok: f3 0f 09 wbnoinvd Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Reviewed-by: Andi Kleen <ak@linux.intel.com> Acked-by: Masami Hiramatsu <mhiramat@kernel.org> Cc: Borislav Petkov <bp@alien8.de> Cc: H.
