the corresponding pad device open, or we get EIO from audio accesses
Explained and fix provided by Nathanial Sloss <nat@n.o>
Note: if we are testing and using real audio hardware, the open
of /dev/pad0 is irrelevant (but harmless, so we don't attempt to
check) and what's more it doesn't matter if it succeeds or fails.
If we're testing under qemu (or any other situation where the only
audio "hardware" is pad) then the open will work, and there should be
no more EIO.
If there is no audio hardware of any kind on the system being tested,
the attempt top open /dev/mixer should fail, and the test will be
skipped.

This test is also marked as failure on other platforms:

Both issues are valid on sparc 32-bit, but the timeout one wins.
- Check if setkey correctly handles algorithms for AH/ESP
- Check IPsec of transport mode with AH/ESP over IPv4/IPv6
- Check IPsec of tunnel mode with AH/ESP over IPv4/IPv6
This macro ships with a MD-specific assembly instruction triggering
a software breakpoint.
Missing instruction for powerpc targets.
This code is used in ATF tests (lib/libc/sys/t_ptrace_wait).
Original patch by Nick Hudson, thanks!
These operations allow to mark thread as a single-stepping one.
This allows to i.a.:
- single step and emit a signal (PT_SETSTEP & PT_CONTINUE)
- single step and trace syscall entry and exit (PT_SETSTEP & PT_SYSCALL)
The former is useful for debuggers like GDB or LLDB. The latter can be used
to singlestep a usermode kernel. These examples don't limit use-cases of
this interface.
Define PT_*STEP only for platforms defining PT_STEP.
Add new ATF tests setstep[1234].
These ptrace(2) operations first appeared in FreeBSD.

This aims to remove MD-specific tests files for ptrace(2).
Prefix i386 and amd64 tests with unique strings "i386_" and "x86_64_".
This removes conflicts with generic tests.

Move common function code into shared subroutine.
While there remove checks for defined(HAVE_DBREGS). All x86 ports offer
debug register accessors.

PR kern/52117 ptrace(2) PTRACE_FORK fails on some platforms
Add message similar to:
We expect two SIGTRAP events, for child 22199 (TRAP_CHLD,
pe_report_event=PTRACE_FORK, state.pe_other_pid=child2) and for child2
(TRAP_CHLD, pe_report_event=PTRACE_FORK, state.pe_other_pid=child)
This should make the expected behavior more clear.

activate it for the current process. It does not work and tests should
not change global system state anyway.
Instead: skip the test is pax.mprotect is not globally enabled. We could
use a better check for this (querying the current processes pax flags),
but unfortunately we don't have one.
