| Message-ID | <q4fbc-4Me-7@gated-at.bofh.it> |
Add rdpkru and wrpkru to the op code map and the perf tools
new instructions test. In the case of the test, only the
bytes can be tested at the moment since binutils doesn't
support the instructions yet. To run the test:
$ tools/perf/perf test "x86 ins"
39: Test x86 instruction decoder - new instructions : Ok
Or to see the details:
$ tools/perf/perf test -v "x86 ins" 2>&1 | grep pkru
For information about rdpkru and wrpkru, refer the Intel SDM.
