Yes, we do. CC Rui and Aaron on power testing.

yes, we have added suspend/resume test in 0day, including both
functionality and suspend/resume performance. It is not widely run
because most of the 0Day testboxes are servers/desktops, now we've just
added some client laptops as testboxes, and will add more in the near
future. :)

I will run native suspend/resume test on laptops and other test boxes
that really support it, and run suspend/resume test in pm_test modes on
the others to help us find more issues.

It's a good plan, thanks! Client devices can be much cheaper than servers.
They have more diversities in HW while being more general available.

On the other hand, if there are PM functionalities that can be tested
inside QEMU, it'll be good to have. Since no real HW can be tested as
cheap and extensive as the large amount of VMs.
