test__insn_x86()

int test__insn_x86	(	struct test *test	__maybe_unused,
		int subtest	__maybe_unused
	)

test__insn_x86 - test x86 instruction decoder - new instructions.

This function implements a test that decodes a selection of instructions and checks the results. The Intel PT function that further categorizes instructions (i.e. intel_pt_get_insn()) is also checked.

The instructions are originally in insn-x86-dat-src.c which has been processed by scripts gen-insn-x86-dat.sh and gen-insn-x86-dat.awk to produce insn-x86-dat-32.c and insn-x86-dat-64.c which are included into this program. i.e. to add new instructions to the test, edit insn-x86-dat-src.c, run the gen-insn-x86-dat.sh script, make perf, and then run the test.

If the test passes %0 is returned, otherwise %-1 is returned. Use the verbose (-v) option to see all the instructions and whether or not they decoded successfuly.

test__perf_time_to_tsc()

int test__perf_time_to_tsc	(	struct test *test	__maybe_unused,
		int subtest	__maybe_unused
	)

test__perf_time_to_tsc - test converting perf time to TSC.

This function implements a test that checks that the conversion of perf time to and from TSC is consistent with the order of events. If the test passes %0 is returned, otherwise %-1 is returned. If TSC conversion is not supported then then the test passes but " (not supported)" is printed.
