I'm on stock ROM but on another kernel.

I have also bought the Franco kernel updater app and installed it.

If I wanna flash this kernel through the app on my stock ROM to replace the other kernel, should I just press "Auto Flash" and that's done?

Thanks

This is my first time with a android that is actually customizable. My last phone was a Motorola Cliq 2. Which apparently no one bought, despite it being a half decent mid-range phone. There were a few developers working on adding custom rooms onto it, but nothing like on the nexus 4. IT'nns

It's defintely a big change from having to wait days/weeks for new developments. To have dozens of different developers working on new changes daily. It's a lot of fun.

[Nexus 4 Original Android Development] StuMcBill:
Ever since I have been on the newer few kernels (r69-r72), I seem to be losing signal completely (Shows No Service), I need to do a manual scan before my phone will pick up a signal?

It probably is just a coincidence that it has been happening since r69.

Anyone else seeing this?

Re: [KERNEL][GPL][N4] franco.Kernel - r72

Im no expert in color calibration or anything, but from what I've gathered from the very knowledgeable people in here, there's a couple of rules:

-try settings at max screen brightness

- not one specific set of values will satisfy every user...

Well i started with visceral's values and tweaked them to my liking, but the problem just seems to be that auto-brightness is a bit low.

¿Anyone know how to modify the auto-brightness thresholds?

Maybe you undervolted too much. When you undervolt too much you will issues like the one you have.

I did take 100mV from everything, but I never selected set on boot, so I guess a reboot will put me back to stock voltages?

That voltage table R72 Any advice for this?

I have now-125mV in all frequencies but I notice it warms a bit my Nexus.
[Nexus 4 Original Android Development] Lownita:
Two questions:

1. The value "brightness" in the color profiles does not have anything to do with the actual auto screen brightness, right? So auto brightness can NOT be adjusted?

2. Every value can have a maximum of 255, just like RGB values?

Thanks!

New to the kernel. Running version #72

Two questions: are there optimum settings that I should input into the Frnanco kernel app or just run as installed?

Second, I notice that by default two cores stay online when the screen is on. Is that by design? or is there something wrong with my setup?
[Nexus 4 Original Android Development] CrimsonSmear:

[Nexus 4 Original Android Development] xhazyx:
Re: [KERNEL][GPL][N4] franco.Kernel - r72

Optimum settings will vary depending on personal use and small differences in the devices (eg. some CPU's can be OC'd higher than others) so tryi the default setting for a while then, carefully, you can start messing around with settings.... Personally, i lowered the highest frequency to 1.3 GHz and lowered the voltages accross the table by -125

By design the latest builds run with *at least* 2 cores online while the screen is on.

echo "255 255 255" > /sys/devices/platform/kcal_ctrl.0/kcal doesn't do it. It seems it changes the numbers (seeing in Franco's app) but doesn't actually change the colours, and after screen off/on they're as they were before.

[Nexus 4 Original Android Development] franciscofranco:
echo 1 > /sys/devices/platform/kcal_ctrl.0/kcal_ctrl

After you screen off you'll lose it. So you really need an app to maintain those settings or set a tasker profile to check when the screen goes off/on to re-set those values. Thats something I've been forgetting as I should've already added a small function call to prevent losing the settings on screen off/on.
[Nexus 4 Original Android Development] franciscofranco:
Tell me more about that Mr. Sherlock Holmes.
[Nexus 4 Original Android Development] Hanny:
whoops, had 2 random reboots today on r72:

1.

while listening to music and some light usage on the phone

screen off

music suddenly stopped playing

no response by touching/swiping the screen, no response with some presses of power button

(did not try 10 sec power button hard reboot)

unplugged the earphone -> full bootanimation from Google logo

no kmsg available for this random reboot

fast chip

UV is at -150mV across the board, -100mV for 1026mhz (therefore total -175)

= this setting was tested with stability test app 384-1512 scaling stability test unplugged

from battery 100% to 0% totally stable on r61 (quad core kernel)

after this random reboot i bumped 25mV up for 1026mhz so total its -150 only, as with all other frequencies

2. (after 4 hours)

after using google maps with GPS for 10 minutes

turned off google maps with back button, i saw the GPS icon still there i didnt know why it doesnt go away, so i wanna try screen off and on

screen off

short bootanimation (no google logo) -> after 3 seconds it vibrates and go into lockscreen

after this random reboot wifi is not usable (stuck at obtaining IP) (tested on 2 routers) until another manual reboot it worked, not a big deal just sayin

kmsg for this reboot attached

both reboots are somewhere after turning the screen off

franco i wonder if its because of some small issues in the new cpu hotplugging algorithm that you are aware of? :confused:

(i understand im on my own during UV but you know the voltages were stable for me on all kinds of usage since r61.

until r69 (theoratically 67) when new hotplugging kicks in i had a few occasional reboots)
[Nexus 4 Original Android Development] franciscofranco:
Nothing is showing in the log about kernel panics. You sure its not something on your rom? Im not saying its not the kernel, but it seems strange that it would reboot with the scenario you just described. Are you using CM?

thanks for the quick reply

nope i never used CM on N4, im using AOKP mainstream builds and did not dirty flash any unofficial variants (Steve, PUB, Krait, anything else)

in the ROM thread there were no reports of random reboots since very long time ago, at least a month i think

last week on 7Feb i had a random reboot after playing Draw Race 2 for 20 minutes. it was on r69. here is the kmsg on that day

just wondering, is UV-caused-instability visible on kmsg logs?

and their similarity at the end is msm_hsic_host msm_hsic_host: USB bus 1 deregistered... da hell is that
[Nexus 4 Original Android Development] franciscofranco:
Yes long ago. I didn't pick it up because it didn't seem very clean to me. I can probably make it cleaner.

CM had a bug that came from Google that basically ****s up in some floating point long division. Steve reported that to Googles gerrit but from answer from them yet. AOKP inherits stuff from CM a lot of times so that might be the reason. GPS and gaming involve a lot of floating point calculations so it might make some sense the bug is on the rom side.
[Nexus 4 Original Android Development] flxdms:
Are you sure RGB is set to 175 175 175? I forgot to add the kcal_ctrl line to the script I posted. I am not familiar with colour controls on franco, and apparently the init.d RGB settings do not stick when you turn off your screen. To be fair, he made an app that works just fine. Buy it if you're going to stick with franco. It has a proper gamma interface specifically designed for his kernel. The app itself is amazing.

echo "175 175 175" > /sys/devices/platform/kcal_ctrl.0/kcal
echo 1 > /sys/devices/platform/kcal_ctrl.0/kcal_ctrl

0x30 being 48... Wrapping to the 8 range would give us 4.. I see no difference in saturation on my screen, and the grey, red, blue, green gamma levels as measured in the app I posted earlier, are identical.

That said, if it's anything like the black property, it may have some affect on banding, which I have not seen any evidence towards though.

I have no clue when 4.2.2 is dropping for Mako. There are no kernel sources for any of the 4.2.2 devices so Google is infringing the GPL license, not that I care much since they only dropped the binaries yesterday. I'm constantly working on my kernel, either its 1.6 coming or 5.0, I get ideas during the day and I learn lots from my co-workers and they also give me ideas. Some of them also bought my app and use my kernel which is kinda cool so they give me feedback.

I need a few breaks, thats why I come to XDA. Its not fun to spend all work day reading OpenGL code :(

I actually don't have a clue. As soon as I knew that 4.2.2 was going to drop late January/early February I shared that to everyone here, guess what 4.2.2 is up! If I knew more I would share, we don't have any NDA that prevent us from talking about what we hear around here. I also know that 5.0 is coming in June (probably shown at IO and released 3 weeks after in early June) and I'm sharing :) Don't worry Mr. Sherlock, you're wrong this time!
