I was thinking of the processor deep sleep state. Guess I'll have to read up on deep idle later. Happen to have any links?

Lot's of info on that page. All kinds of good stuff in his github too. Gonna see if I can't get deep idle in my kernel too, sounds tasty.

EDIT: marcusant, did you actually get deep idle to work in your kernel? I've applied all the patches from ezekeel's github, and changed it to be enabled by default, but nothing is showing up in /sys/class/misc/deepidle like it should. The patches applied cleanly with only a minor change to one file path, and I had no problems compiling. For the look of it, things did get compiled with the rest of the kernel, not show why nothings showing up.

EDIT2: Well that was stupid. Forgot to clean before rebuilding. Plenty-o-errors to deal with now.

I have it in. It compiles fine (after I fixed the errors) and the sysfs interface is there but it refuses to enter the didle state for some reason (or fails to report it correctly)

That's exactly where I'm at now. Playing music with the screen off for a while is supposed to get it going, but all I get is this:

root@android:/ # cat /sys/class/misc/deepidle/idle_stats
idle state total (average)
===================================================
IDLE 136313ms (2ms)
DEEP IDLE (TOP=ON) 0ms (0ms)
DEEP IDLE (TOP=OFF) 0ms (0ms)

I'm thinking it might have something to do with iterrupts having different names between the phones. There's a series of things in there that are supposed to prevent deep idle, maybe one of those is the name of something that's always enabled on the epic.

EDIT: found some info but putting in lots of log messages. Looks like (at least) the following code is keeping it awake:

Code:

/* check power gating */
val = __raw_readl(S5P_NORMAL_CFG);
if (val & (S5PV210_PD_LCD | S5PV210_PD_CAM | S5PV210_PD_TV
          | S5PV210_PD_MFC | S5PV210_PD_G3D))
    return 1;

When the screen is off, S5PV210_PD_TV and S5PV210_PD_MFC are always non zero. Music playing or not. According to power-domain.c, the tv one appear related to tv-out which can probably be ignored. No idea what MFC does, but some quick googling seems to suggest something relating to video encoding. Gonna see what happens if I ignore them...

zman, I think I know how to fix deep idle. Can you pm me your gtalk? I will try applying and compiling when I can access a pc. It may not be the entire issue but it is likely stopping it also.

Sorry to not reply for so long. Been busy with grad school. I think you found my gtalk. I tried what I mentioned above, disabling the check for tv and mfc, and also disabled the check for bluetooth since it was always reporting it as on. This caused it to repeatedly attempt to enter didle then immediately exit, also preventing deep sleep from working at all. Problem seems to be the part where it checks VIC status register and does goto skipped_didle if any are non_zero. It ands together S5P_VIC[0-3]REG(VIC_RAW_STATUS) and S5P_VIC[0-3]REG(VIC_INT_ENABLE) to check if any are non-zero. I haven't checked the values of VIC_RAW_STATUS regs, but 2 of the VIC_INT_ENABLE regs are always non-zero. I tried ignoring the goto statement to allow it to go into deep idle, but that just caused a kernel oops or sleep of death. That's pretty much where I got stuck. I think these VIC registers are related to the interup controller, but I can't find any additional info on them. I never got a chance to try disabling coresight, so maybe that has something to do with it. Did you have any luck?
