So I take everyone's latest and greatest product and injudiciously type the
above command.  The result five minutes later is at
http://userweb.kernel.org/~akpm/borkage.jpg.  See if you can count all the bugs.

Sorry, but I've had it with this stuff and I'm tired of fixing everyone else's
stuff.  I'm just going to ship it.  Good luck.

Heh.  Laptop suspend to anything has been so broken for so long in the
-mm series on my Compaq R3000 that I didn't even know it was ever
supposed to work.

It gets broken more often than anything else.  I do test each release on
two laptops and I get to do a lot of bisection searching and
grumpygramming as a result.

Probably it would be more efficient to have the people who wrote the code
also test it.

Well, that would certainly help.

I do test all of my patches and generally all of the patches I sign off, but
surely that's not enough.

It is far too easy to take a cursory glance, say 'That looks okay' and
move on to the next thing, isn't it? I was horrified when I saw the list
of acks etc (including me) on the commit with the helper_unlock issue we
just fixed. It's truly scary to think that none of us looked closely
enough to pick that up at the time.

Well, the code in question was not in the patch, so if you didn't actually look
at the _patched_ kmod.c, you would have a little chance to spot it.  I
overlooked it, even though I did look at the patched file ...

Still, this particular problem hasn't been triggering it testing for quite some
time.

please add a .config option dependent on CONFIG_DEBUG_KERNEL=y [and 
default-disabled] that auto-tests suspend/resume functionality 60 
seconds after hitting user-space (the suspend/resume cycle kept small 
via a small RTC timeout) and s2ram correctness will be tested _a lot_ 
more.

(it doesnt matter if graphics does not resume fine - at least for my 
tests)

kprobes had similar problems and it now has a few simple smoke-tests - 
which i just saw trigger on a patch that i did not notice would break 
kprobes. I think this should be done for all functionality that is not 
regularly triggered by a normal distro bootup (and which is easy to 
overlook in testing).

Seeing as we're so lame about being able to distribute userspace stuff:
create a shell script in /proc/rc.kernel and start teaching initscripts to
run it.  Then we can modify it at will.

I hate me.

With all the discussion lately about boot-time smoketests and self-tests
maybe this kind of stuff would be a good first candidate for useful
new early-userspace functionality.  Then the kernel build could be
taught about building an initramfs that runs a bunch of tests
and leaves the user in a shell letting them know if it passed or not.

This would be a great way for increasing the number of testers, just
ask them to build with that option and a _known_ testsuite could
be reported as working or not.

Or maybe I'm out to lunch....

would be fine to me. The problem isnt just distribution and the tests 
getting out of sync with the kernel (and its capabilities enabled in the 
.config, etc.), the other problem is unintrusive testing: i for example 
use unmodified images of various distributions, with only a new bzImage 
plopped in. That is an intentionally minimal impact test vector, any 
userspace side changes are discouraged. And that's how many people test 
new kernels, they just plop it in. The moment we require any userlevel 
changes, the testing barrier increases significantly.

[ and a Friday rant: that's why the objection against my 
  make-relatime-actually-useful-to-people patch is so stupid, 
  shortsighted, self-defeating and misplaced. The "Dont put policy into 
  the kernel, use a new mount option and update your /etc/fstab" 
  stupidity that people have been repeating for 10 years without 
  thinking about it is a move that scares away 90% of our testers and
  99% of the distros. See:

    http://people.redhat.com/mingo/relatime-patches/improve-relatime.patch

  Trivial improvement, it's 6 months and still not upstream. We are just 
  so good at shooting in our feet by creating artificial barriers and 
  making it as hard as possible for people to actually use our kernel 
  features ;-) ]

Yes, that might work.

Ingo wanted simple sleep self-test... Here's something.

set_alarm needs to move into rtc-cmos, and I guess I should boottest

Ok... it needs to depend on cmos_rtc... Plus timeout needs to be
longer, because if it fails to suspend within timeout, it will hang.

I actually tested this version... and it has some problems with
nohz. I have to press shift (probably any key will do) to make it
suspend :-(.

How big is your autotest farm, btw?

Why compiling it uncoditionally?  What would be wrong with

obj-$(CONFIG_PM_SLEEPY_TEST		+= sleepy.o

(besides the missing parenthesis, of course)?

cmos_set_alarm() takes a struct device * too.

Set alarm belongs in drivers/rtc, moved now.

Here you go, but notice that it needs nohz=off here. (Or press shift
few times, that makes it proceed). idle=poll also works around that
specific problem, but provokes deadlock in sysfs instead :-(.

Big fat ACK from here. Suspend issues in past few -mms were *very* hard (and 
time consuming) to track down.

Looking forward to test suspend of -rc8-mm1 :),

it's really all a matter of reducing latencies. Testing suspend/resume 
is manual work currently (it either needs me hit a key on the laptop or 
necessiates the use of a test-script that might or might not work 
depending on whether the new /dev/rtc driver is enabled). So few people 
besides those that rely on it will do it. The more a patch that breaks 
suspend is out in the open unidentified, the more damage it does: it 
gets into more trees, gets harder to bisect, etc.

So please give us overworked maintainers an easy to use .config option 
dependent on CONFIG_DEBUG_KERNEL=y that automatically triggers a simple 
suspend+resume sequence 60 seconds after bootup. It would be godsent. 
(dont worry about proper gx resume) I compile and boot up every patch i 
add to x86.git, so this would catch crap the moment we add it to the 
tree.

The other, more long-term trick is to make rarely used functionality 
more widely used. Consolidate code. Try to merge as much of 
suspend/resume with bootup/module-insert/shutdown sequences as possible. 
Suspend unused devices more agressively - such as non-mounted block 
devices or downed networking ports. Try create more network effects with 
other functionality, suspend and resume is not just about suspending 
laptops, it can/could be used for so much more stuff. Try to get Pavel's 
"Sleepy Linux" concept to work reasonably well - so that more people 
(including developers) would use it in a daily basis.

Test coverage of a given piece of code is a direct function of its 
utility and of its ease of testing. Decreeing "this is important" really 
wont get more testing done. What you should realize i think is that this 
is not a social/mindset problem (so no need to get frustrated about it), 
this is a mostly technology problem: you can gradually _code_ your way 
into people's test efforts.

Like I said in another thread, please try without

If that still doesn't work, it's not my fault. ;-)
