Re: [linux-pm] sleepy linux self-test

Hi!

The changes look good to me.

They feel unfinished to me though. :)

Like using "jiffies" instead of a clocksource, which makes trouble
since the timing covers periods with IRQs disabled. And the test
mode parameter needs work.

Well, I'd say that timing has bigger problem, right?

It is

set alarm
suspend system
| poweroff
alarm expires
system resumes

... so you are measuring resume time + sleep time, no?

Well, it would be nice to have this feature in as soon as reasonably possible,
so that people can include suspend tests in the automated testing.

Except ... "rtcwake" (from util-linux-ng) already supports such
testing, albeit from userspace. But not the timing tests.

What was the rationale for wanting this done in-kernel? (Other
than to know it can work portably.)

Ingo has to answer this one...
