+.Sh SYNOPSIS
+.In sys/systm.h
+.In sys/kernel.h
+.In sys/module.h
+.In sys/tbridge.h
+.Pp
+Functions:
+.Ft int
+.Fn tbridge_rpintf "const char *fmt" "..."
+.Ft void
+.Fn tbridge_test_done "int result"
+.Pp
+Macros:
+.Fn TBRIDGE_TESTCASE_MODULE "name" "struct tbridge_testcase *testcase"
+.Pp
+Defines:

+.Dv RESULT_SIGNALLED ,
+.Dv RESULT_NOTRUN ,
+.Dv RESULT_FAIL ,
+.Dv RESULT_PASS ,
+.Dv RESULT_UNKNOWN
+.Pp
+Callbacks:
+.Ft typedef int

+.Ft typedef void
+.Fn tbridge_run_t "void *"
+.Sh DESCRIPTION
+To create a new kernel testcase
+.Sq testfoo
+the following is required:
+.Bd -literal
+TBRIDGE_TESTCASE_MODULE(testfoo, &testfoo_case);
+
+struct tbridge_testcase testfoo_case = {
+       .tb_run = testfoo_run,
+
+       /* The following are optional */
+       .tb_abort = testfoo_abort
+};
+.Ed
+.Pp
+The
+.Fa tb_run
+callback is called from a separate kernel thread to start testcase
+execution.
+.Pp
+The
+.Fa tb_abort
+callback is optional, but highly recommended.
+It is called whenever a testcase execution times out, so that the
+testcase can clean up and abort all running tasks, if possible.
+If this is not applicable to your thread because it is impossible
+to interrupt, set to
+.Dv NULL .
+.Sh FUNCTIONS
+The
+.Fn TBRIDGE_TESTCASE_MODULE
+macro declares a
+.Nm
+testcase kernel module.
+.Fa testcase
+is a structure of type
+.Ft struct tbridge_testcase ,
+as described above.
+.Pp
+The
+.Fn tbridge_printf
+function acts as a kprintf replacement that will log all the output
+into the testcase metadata that is passed back to userland upon completion.
+Its syntax is equivalent to that of
+.Xr kprintf 9 .
+.Pp
+The
+.Fn tbridge_test_done
+function should be called whenever a result for the testcase is available.
+The parameter
+.Fa result
+should be set to one of the
+.Dv RESULT_
+defines.
+.Sh SEE ALSO
+.Xr dfregress 8
+.Sh HISTORY
+The
+.Nm
+module first appeared in
+.Dx 2.13 .
+.Sh AUTHORS
+The
+.Nm
+module was written by
+.An Alex Hornung .
