While doing some tests with Thumb kernel, i had some trouble with Powertop as the CPU in idle was too much on C3 state if i compare it without Thumb. I did this check because i had a little loss in battery consumption.

(the following is the short explaination, i can provide a more complete test process and info):
So as i tinker a lot with my N900, i though it is because of something else, so i did a backup and flashed the N900 with PR1.3 emmc and rootfs.
Then installed CSSU, KP50, KP-Settingsv14, batterygraph, rootsh and leafpad (yes, i am unable to understand how vi works)

Then did Powertop and dmesg to see the evolution. Everything was fine until a few hour after the reinstall, i suddenly got a big consumption drain. Confirmed in batterygraph.

So i started powertop and found a lot more interrupt than usual. Also, core, neon and ina2 in powertop result are always 100% ON.
then started DMESG and found out a lot of "procwrap_detach: deprecated dspbridge ioctl.
I also found this kind of error:
Code:

I somehow found out that this is happen while recording/playing movie.
I uninstalled KP50 and KP50-Settings, problem gone!

I also tried with DSP overclock profile.

This is something i tested a lot with different configuration, CSSU or not, DCIM folder on Internal/uSD, swap on internal/uSD/both, KP50/OMAP. And i only got this problem while KP50 installed, no matter the rest of my configuration.

I found a solution, it is to install 720p packages once KP50 is installed. Now i don't have any error.

I am using KP50 since the very beginning and never experienced this error, right is that i had 720p installed since the very beginning too...

I did not find any info about KP50 requiring 720p package to run properly, i checked TMO page and wiki.

So can any of you confirm this?



Thank you
IIRC kps v14 isn't compatible with thumb2 on n900.

as i explained, i was testing thumb2 and reflashed to stock, then installing CSSU and KP50 + settings.
So if there is a problem, it is with the normal "stable" KP50 installed

plzzz help me. i cant uninstall power kernel v50. i clicked the nokia kernel symbol. after few min it appeared. ( successfully restored nokia kernel). then i rebooted and there was still kp50 option in the multiboot section. i tapped 3 to select it. then it loaded kp50. so it wasnt uninstalled. but the nokia kernel option wasnt there. then i followed the wiki steps. rebooted the device. my stock kernel was rebooting and kp50 showed guru meditation. my phone is in a reboot loop now. i restore my backup but unfortunately i created the backup with my kp50 installed. plzz help me to uninstall it safely. i will install cssu thumb. that is why.

many thanks Pali!
I hope to find the time to look into all the hostmode related stuff. How would I check for kernel-feature-XY at runtime?

It allows apps to Requires: kernel features that they need, instead of depending on kernel-power versions.

tl;dr, kernel-bfs and others should also follow suit to include features they support.
