[PATCH] Input: serio - re-add thaw (and add freeze)

[PATCH] Input: serio - re-add thaw (and add freeze)

[Alan Jenkins]

633aae2 "Input: i8042 - switch to using dev_pm_ops"
removed handling for PMSG_THAW, causing obscure breakage.

It can break if you press keys during hibernation,
which causes subsequent keypresses to be lost -
so you can't cancel s2disk by pressing backspace -
and then just before system poweroff you get
"psmouse.c: Failed to deactivate mouse".

So let's add the thaw handler back.

Also set the freeze handler.  It looks like PMSG_FREEZE
didn't do anything in the past, but I think that must
have been an oversight.

We do not need to do anything special at freeze time that is why there
wasn't freeze handler. And so thaw should be pretty much noop as well.

What supports canceling s2disk by backspace? I need more data to figure
out what is going on. At the moment input should be fully-functional
until poweroff.

I don't understand the driver; I'm just mindlessly reverting the change 
that caused the regression on my specific machine.  My guess is the 
problem happens when input events occur while interrupts are disabled to 
make the atomic snapshot.

I could be wrong about whether a freeze is appropriate.  I added it 
since I didn't know whether it would be safe to add the thaw without the 
freeze.  If you can patch the problem then I'm happy to leave that 
question up to you :).

> What supports canceling s2disk by backspace?

If you want to test this yourself, you might find it easier to use 
pm_test (as in Documentation/power/basic_pm_debugging.txt) to run a 
freeze-thaw cycle without powering off.

In order to reproduce this reliably, I have to press keys quite quickly 
while the kernel is hibernating.  E.g. hammering the Enter key does it.


I'm actually using s2disk(8) from the "uswsusp" package, but that 
requires a bit of setup.

You may need to create /etc/suspend.conf in order to test with it.  (The 
debian package provides semi-automatic configuration, and renames the 
config file to "uswsusp.conf").  It is installed by default in debian 
unstable.  If you use pm-hibernate, note that it will probably switch to 
using s2disk, assuming you install it in the standard location (and not 
/usr/local).

In general I wouldn't recommend installing it from source, because you 
need to add a "resume" program to the initramfs.  That said, you don't 
need to resume in order to test this specific problem, so long as you 
don't mind an unclean shutdown.

Sure.  I can reproduce this very easily on my machine; just let me know 
what data would help.

I've hacked s2disk to abort automatically before image writeout 
(effectively doing pm_test in userspace).  Here is a full dmesg, showing 
a freeze-thaw cycle after enabling i8042.debug using sysfs.  I'm 
pressing Enter throughout the test, and the keyboard dies as a result.  
When I shut down (using acpid and the power button), I get the same 
message "psmouse.c: Failed to deactivate mouse".

Note that I continued to press the Enter key after the free-thaw cycle, 
but no further i8042 debug messages appeared.
