Subject: [PATCH 1/5] Add ssdd test to the rt-tests suite
The following program might make a good addition to the rt
test suite. It tests the reliability of PTRACE_SINGLESTEP.
It does by default 10,000 ssteps against a simple,
spinner tracee. Also by default, it spins off ten of these
tracer/tracee pairs, all of which are to run concurrently.
Starting with 4.13-rt, this test occasionally encounters a
sstep whose waitpid returns a WIFSIGNALED (signal SIGTRAP)
rather than a WIFSTOPPED. This usually happens after
thousands of ssteps have executed. Having multiple
tracer/tracee pairs running dramatically increases the
chances of failure.
The is what the test output looks like for a good run:
forktest#0/22872: STARTING
forktest#7/22879: STARTING
forktest#8/22880: STARTING
forktest#6/22878: STARTING
forktest#5/22877: STARTING
forktest#3/22875: STARTING
forktest#4/22876: STARTING
forktest#9/22882: STARTING
forktest#2/22874: STARTING
forktest#1/22873: STARTING
forktest#0/22872: EXITING, no error
forktest#8/22880: EXITING, no error

forktest#4/22876: EXITING, no error

All tests PASSED.

Subject: [PATCH 1/2] hwlatdetect: disable/enable c-state transitions during
detection
Recent performance tuning problems led me to realize that just running
at fifo:99 and turning off interrupts isn't enough while looking for
BIOS induced latencies. Power savings logic is built into most modern
cpus and so must be disabled while looking for BIOS induced (SMI/NMI)
latencies.
Use the /dev/cpu_dma_latency mechanism to disable c-state transitions
while running the hardware latency detector. Open the file
/dev/cpu_dma_latency and write a 32-bit zero to it, which will prevent
c-state transitions while the file is open.

+.SH NAME

+.SH SYNOPSIS
+.B ssdd
+.RI "[nforks] [niters]"
+.SH DESCRIPTION
+Have a tracer do a bunch of PTRACE_SINGLESTEPs against
+a tracee as fast as possible. Create several of these
+tracer/tracee pairs and see if they can be made to
+interfere with each other.
+The tracer waits on each PTRACE_SINGLESTEP with a waitpid(2)
+and checks that waitpid's return values for correctness.
+.SH OPTIONS
+.B nforks
+number of tracer/tracee pairs to fork off.
+Default is 10.
+.br
+.TP
+.B niters
+number of PTRACE_SINGLESTEP iterations to
+do before declaring success, for each tracer/
+tracee pair set up. Default is 10,000.

Subject: [PATCH 4/5] ssdd: remove sleeps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There two sleep functions which ensure that the forked function sleeps
and does not spin until everything is setup. There is no need for that,
the scheduler will take care of that anyway. Also that sleep may
complete before or after the testcase starts. If it completes afterwards
then the testcase waits to start so…
Remove the sleep, it does change the outcome of the testcase.
