| Message-ID | <uaOgN-1p8-7@gated-at.bofh.it> |
This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.
The problem happens because:
- press power button:
- system emits 0xc0 (power press), event ignored
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- set wakeup_mode to true
- system goes to s2idle
- press power button
- system emits 0xc0 (power press), wakeup_mode is true,
system wakes
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- system goes to s2idle again
To avoid this situation, process the presses (which matches what
intel-hid does too).

I'd like to see agreement from AceLan, but this should go into the 4.13 rc cycle (at rc3 currently). -- Darren Hart VMware Open Source Technology Center

The patch makes sense to everyone involved and fixes an annoying issue, so I don't see any real arguments against applying it. Please feel free to add my ACK to it if that helps. In any case, it has to go in before https://patchwork.kernel.org/patch/9873163/ does, is if it doesn't go into 4.13-rc after all, please let me know. Thanks, Rafael

Thanks for chiming in all the same - and normally I'd have provided for more time. In this case, I will be away for a few days, and it was important to get this in sooner rather than later in the RC cycle. -- Darren Hart VMware Open Source Technology Center
