Anyone can tell me what is "Max compaion core frequency" ?
[Nexus 7 Original Development] franciscofranco:
Maximum frequency of the companion core?
[Nexus 7 Original Development] DJLamontagneIII:
Tegra 3 has a 5th low power core called the companion core that handles the low speeds to save power and Franco made it so you can bump up the speed of this core so you can try to theoretically save more power
[Nexus 7 Original Development] airmaxx23:
I tried bumping mine up to 550MHz and it instantly locked up....:( I'll try something lower instead.
[Nexus 7 Original Development] friedsonjm:
I'd be seriously worried about burning that core out....
[Nexus 7 Original Development] nuwan32:
What's the stock clock if this core and how do you change it? I don't see it in Franco kernel app
[Nexus 7 Original Development] airmaxx23:
It's in the Frequencies/Governors tab, just under Max GPU Frequency. I'd like to know the stock speed as well.
[Nexus 7 Original Development] Wynnded:
It's under the OC/UV settings where it says Max Companion Core frequency in Ver 7 of the app.
[Nexus 7 Original Development] :
Wow coolness!! I just received the Franco app update to 7.0! I'm so gonna break something. Haha.:what::D:cool:
[Nexus 7 Original Development] nuwan32:
Oh no wonder, haven't updated yet

Franco, what's going to be under 'sound control' in your app?
[Nexus 7 Original Development] ÜBER™:
I would say its a loose "string" :D
[Nexus 7 Original Development] icytrey:
Stock speed is what its set at by default.. 500
[Nexus 7 Original Development] JDCFH:
How do we get GPU frequency to stick?
[Nexus 7 Original Development] Wynnded:
Wait for Franco to decide that's what he want's. It'll come.

I'll ditch Chrome when you pry it from my rigor mortissed fingers. Or do you have a better way for me to immediately continue where I left off on my work PC, laptop, phone and home PCs, with all my tabs, passwords, cookies and saved forms? And all of it encrypted. Don't say Firefox.

I haven't had a single SOD with r23 on PA 2.2. Thanks for the great kernel.

[Nexus 7 Original Development] JDCFH:
You can already set it via commands but there is now an option in the app...
[Nexus 7 Original Development] .torrented:
Edit* I didnt read the other quoted message where he says just UNDER the GPU, I thought he was talking about the GPU itself. Yes its 500MHz
[Nexus 7 Original Development] ÜBER™:
Go back a couple pages.. he was talking about the Companion Core not the GPU.
[Nexus 7 Original Development] extremetempz:
gpu

I have Franco.kernel r23 with Franco updater 7.0 when I put the GPU at 500 I see no difference and when I got to sys/devices/CPU there's no CPU0 what could be the problem
[Nexus 7 Original Development] Wynnded:
Right. But you asked how to get it to stick, after a reboot I'm guessing. If not, my error.

My reply was based on the Changelog for the most recent version of Franco's App:

What's in this version:

7.0

Common:

* Slight update to the app icon courtesy of lab75

Galaxy Nexus:

* Calibrated Voltages panel re-designed and its now called Device Monitor.

* In the Device Monitor from r290 onwards you'll be able to see the current GPU clock live

* General fixes

Nexus 7:

* Add GPU overclock preference (not set on boot)

* Add preference to choose maximum frequency of the companion core (not set on boot)

One X:

*

Add GPU overclock preference (not set on boot)

Not set on boot indicates that it will not stick on a reboot. I suspect that when Franco elects to have it stick (likely based on user feedback), he will make that option available via a setting in his app. At this time it's a no-go. :)

[Nexus 7 Original Development] mullemulle86:
That has nothing to do with performance. Francos kernel limits fps to 60 fps. More than 60fps is absolute useless...

[Nexus 7 Original Development] gokart2:
Just one question....

When echoing freq do I use MHz value (415, 446, 484...) or convert it to Hz. Because on my e3d it needs to be in Hz (for 320mhz I need to echo 320000000)
[Nexus 7 Original Development] friedsonjm:
I have found a great difference between 418 and 484 - at 484 the home screen 'lag' disappears, which is the only issue I've had.
[Nexus 7 Original Development] extremetempz:
just mhz so you right 500 for 500mhz
[Nexus 7 Original Development] gokart2:
Thanks for the prompt reply! Greatly appreciated. Almost tried 520000000mhz GPU....LOL

cpu reset

whenever i put the cpu at 1100mhz for reading and turn the screen off and on it resets itself why??
[Nexus 7 Original Development] M3drvr:
Because you touch yourself at night
[Nexus 7 Original Development] extremetempz:
That Makes Absoloutly No Sense and im not a 30 year old virgin unlike yourself
[Nexus 7 Original Development] ÜBER™:
Because Franco hasn't patched PowerHAL for the N7 yet.
[Nexus 7 Original Development] extremetempz:
is he ever going to do it?
[Nexus 7 Original Development] ÜBER™:
Not with that attitude he won't. :rolleyes:
[Nexus 7 Original Development] TheByteSmasher:
What's powerHAL?
[Nexus 7 Original Development] ÜBER™:
Pro tip don't make the companion core max less than 400 otherwise it won't work.... it stopped using 100Mhz when set to 300Mhz max.
[Nexus 7 Original Development] friedsonjm:
Seems to me that setting it to a lower limit, i.e., 400, would just force the other cores to kick in sooner - not sure why that would be good.
[Nexus 7 Original Development] hospital349:
I haven't flashed franco.kernel since r13 and decided to go elsewhere for a while. Jumping to r23 a few weeks later; the improvements are ginormous and very visible. They should be celebrated!

Thanks for all the hard work that has gone into it. I'm officially 100% satisfied with a kernel, for the 1st time since purchasing my N7.

The app is a real bonus and a big bonus at that. It kinda brings the user experience around full circle and I literally cannot live without it. No other app even comes close. The only 2 improvements I can possibly suggest are the options to set the GPU & voltage values on boot, as it'll make things a little more convenient when deciding to reboot.

Either way, I'm a satisfied user and cannot express my gratitude enough to you franco!

Cheers man. :good:
[Nexus 7 Original Development] osm0sis:
I don't think it changes the limits of when it will switch... it's basically just a different kind of "screen off max", so it could reduce idle drain.

Edit: Likely with the same risk of messing up the race-to-idle if you set it too low.
[Nexus 7 Original Development] cabagekiller:
What is the max most people set for the companion core and the GPU? I tried faux's amount and got reboots. Not a comparison I'm just curious. I use this kernel for both my N7 and galaxy nexus.
[Nexus 7 Original Development] ÜBER™:
400 for the CC. And 484 for the GPU. Or 512. I tried 700 for a benchmark and worked flawless.
[Nexus 7 Original Development] franciscofranco:
Yes I have something to adjust to prevent a crash when setting the companion core to a much lower value.
[Nexus 7 Original Development] friedsonjm:
Heat...

I am beginning to suspect that there may be a simple reason 'some' N7's are having crash issues with this and other kernels/ROMs. I have a small temperature & CPO widget, and also use Sense Analog Clock w/system data, and I have been paying attention to - temperature. FULL DISCLOSURE: I use a case that is very solid and enclosing, as I travel a lot and want my N7 protected well, and that may be keeping some additional heat in via insulation.

In any event, I notice that the N7 starts out at about 79.5F, but with even moderate use, is over 85F. I use mine mostly for reading news and books, I don't play games on it, and only review the occasional youtube news video. Could the 'culprit' be simply overheating?

It would be interesting to have some small app that would record CPU, GPU & memory use, temperature, and 'crash' information - we might be able to get to the 'bottom' of the sporadic freezes/crashes that some are experiencing.

Will cross post this in a couple of places. jf
[Nexus 7 Original Development] airmaxx23:
85 degrees is still very cool, when playing graphic intense games mine runs around 130 degrees. With normal use it's between 85 and 110 degrees.
[Nexus 7 Original Development] ÜBER™:
Lol only 85°F? :rolleyes:
[Nexus 7 Original Development] leelaa:
Big thanks franco. Running great here. Ive had my gpu@520-600 depending on how i feel. Really love this custom gpu scaling. Battery is great too. This will be the ultimate kernel.
[Nexus 7 Original Development] sruel3216:
@franco i know for the gnex you have said that 729 is optimal for performance and battery since the cpu wont jump up and down so much while doing small task. do you recommend i higher min then 100mhz? i have noticed when setting it at 400min it seems to stay there with little jumping to other freq
[Nexus 7 Original Development] ÜBER™:
It shouldn't be settling at 400 at least all the time. It wont show it in certain cpu watching apps.. but it does go lower than 400. When it does its using the companion core (5th virtural core) and idles at that to save battery. I noticed that with Ondemand it will use 400 and then 100 however with Interactive it uses 400... jumps too 500... then to 200.. then finally idles at 100. Based on CPU Spy. Just keep the minimum 100. I also wouldnt base that off of apps that monitor the CPU actively as its using the CPU to monitor it.. that is why you see the jumping. ;)
[Nexus 7 Original Development] sruel3216:
im saying if i set the min to 400 it will settle there and not ramp up often. but if i set the min to 100 i can see the cpu ramp up to 400 and then back down to 100 every few seconds. i feel like this ramping up and down every few seconds will hurt battery more then save
[Nexus 7 Original Development] olivercervera:
Franco, when you will post a changelog file on your server like Galaxy Nexus one? To find the news of a release a spend a lot of time :(

EDIT: Just find out that 23 has no changelog. But my request is still valid!!

Love your kernels! :D
[Nexus 7 Original Development] ÜBER™:
No.. it'll eat more battery idling at 400 than it would at 100.. and like i said if you using a CPU monitor.. its making the CPU jump trying to poll the CPU for its frequency. Keep the min at 100 or do whatever you want. .really.
[Nexus 7 Original Development] nuwan32:
Yea, it doesn't take extra power to jump frequencies, it would save power steering a lower min since it will use lower voyage at that frequency. It's not like turning on a computer, where a high initial voltage is needed, it will always use the defined power at that frequency.. as long as smart reflex is disabled
[Nexus 7 Original Development] sruel3216:
i understand what you guys are saying. i was just curious cuz on the gnex he recommends 729 as a min rather then 384 as a min due to the fact that when at 384 your cpu will ramp up and down to 729 when doing small task such as syncing email. franco did test and found that 729 as a min was optimal for performance/battery since he did not find a significant drain to the battery cuz 729 is still such a low freq. 729 will complete these small task faster and get back to idle sooner.

i know this is a different device, but still same logic
[Nexus 7 Original Development] nuwan32:
Depends on how you use your device. 729 min it's horrible for me since I listen to lots of music daily and it drains my battery quicker
[Nexus 7 Original Development] osm0sis:
Just to set the record straight, I've never seen Franco recommend a 729 min for the GNex, he has always recommended his own default, which is 384 min. He has 729 set as the default screen off max, and as the default hispeed_freq for interactive governor. That's it. :good:
[Nexus 7 Original Development] ÜBER™:
Yeah he got it twisted.. also somebody else suggested using 729 as the min.. not franco :).
[Nexus 7 Original Development] riggs170:
Anyone having SOD while running r23 and paranoid android 2.2
[Nexus 7 Original Development] sruel3216:
yes franco def has said this. he was the reason i started using 729 as min. it was 700 back when he started since he didnt overclock the mpu 5% yet
[Nexus 7 Original Development] nuwan32:
I use that exact combo and no sod ever
[Nexus 7 Original Development] riggs170:
Thanks for the reply maybe I should start from scratch
[Nexus 7 Original Development] nuwan32:
I don't think it's a problem on your part, since others are having this problem also. Have you checked the last kmsg after you got a sod?
[Nexus 7 Original Development] nw21st:
I use both too. Been having SOD's also...
[Nexus 7 Original Development] nuwan32:
Pretty sure this is a hardware specific issue, I use this and under volt a LOT, my 100 mhz step is 600 mV lol. It's just like how some galaxy nexuses can run 512 gpu but others artifact. Hopefully Franco will find a fix for these sod's.
[Nexus 7 Original Development] .torrented:
No SOD's here using same combo

[Nexus 7 Original Development] DJLamontagneIII:
Hey Franco sorry for the off topic question but is there a chance you could enable your paid app to go into landscape
[Nexus 7 Original Development] :
I did a full wipe and ran Bugless Best for two days. Now that I felt comfortable enough to flash r23 back, no SODs in the last two days. :)

Maybe it was something in my ROM install (stock JZO54K) after all.
[Nexus 7 Original Development] cwc3:
r23 has been great. Enjoyed actually getting more than 6+ hours for once. Haven't charged in almost 3 days. Interactive/bfq/forced GPU ui/1300-100/untouched voltages/dimmer off/fsync disabled. Llama disables my WiFi after 3 mins screen off. Screen brightness 0-20%.

Dirty flashed 3 aokp nightlies. Plenty of reboots/cache cleaning. 0 SODs.

Thanks Franco.
[Nexus 7 Original Development] franciscofranco:
For a few months when I started with the GN I had set the mininum frequency to 700Mhz because I wanted the race to idle to kick in very fast and I felt 350Mhz to be too slow for me. I got tired of "umg y 700mhz minimum, battery drainz faster?!?!" And made a few adjustments to the frequency values and changed it to 384Mhz. In the LONG run its a bit better on the battery setting it as 384 because 729 has a tied connection to a higher OPP core entry and it caused CORE to be using a higher frequency most of the time and using more voltage. This was GN case but I dont know about the N7 too early to tell whats best or worse :)
[Nexus 7 Original Development] friedsonjm:
N7 up 87 hours now without any issues on this kernel, Glazed 2.0 ROM; however, CPU Spy shows only the following speeds used:

[Nexus 7 Original Development] neoblood3d:
Can I get an acknowledgement on this request please? Yay or Nay? Just curious what you think Francisco. I am not a programmer I was just sort of wondering why all these kernel code guys didn't include this stuff by default. Thank you for your time.
[Nexus 7 Original Development] eugenechiuu:
Theres somethin wrong with my battery meter.. when i turned wifi back on after 8hours deep sleep.. the battery meter suddenly drops significantly. e.g. 6% for 8 hours sleep.. is this normal? Note: The 12pm point in the photo
[Nexus 7 Original Development] formicae:
I don't think there's anything wrong, it's just not polling the battery when it's in deep sleep.
[Nexus 7 Original Development] eugenechiuu:
so it's normal? and it keeps me wondering why the battery drain is the same as when I have wifi always on though..

supposedly the location services is not working when there is no wifi, I would think that the battery drain is much lesser..

It was only around 3% for 8 hours in the past when I was with other kernels, but the circumstances were that my wifi was set to off when sleep, with Franco's I have to set it always on to avoid SOD and it seemed to have impact the stand by battery life...
[Nexus 7 Original Development] formicae:
Oh, maybe there is something about the battery meter then. When you leave wifi on and it goes into deep sleep, is there still a gap in the wifi usage bar? If so, then maybe GSam is inactive during deep sleep (because, you know, deep sleep) and just updates when you come out of sleep. Incidentally, if GSam is polling all the time when your device is awake, is going to take a toll on your battery life. Even if it's negligible.

What does the stock battery history graph in Settings look like?
[Nexus 7 Original Development] sruel3216:
this is all i was wondering. thanks.

also, i woke up to a sod this morning. i coulnd get a kmsg since i was rushing for work. i had min 100 max 1300 and gpu 550. il try stock gpu and i think il raise the min to 200 to see
[Nexus 7 Original Development] franciscofranco:
It *might* be because of the GPU. If it happens again with stock GPU clocks let us know please.
[Nexus 7 Original Development] eugenechiuu:
It's the same thing, a sudden drop in 6% the moment I turn on the wifi
[Nexus 7 Original Development] demandarin:
I noticed my gpu is at stock 416mhz(confirmed by method checking in OP). I know I can change it but is this correct for this r23 kernel out the box?

Been running r23 since it first released. No issues at all. Battery life seems great and not a single SOD. Sleeps like a baby also ;) great work OP

For people having issues or SOD..first, try flashing Faux new reset kernel for 4.1.2. Then flash Franco r23. That's what I did and has been running great ever since.
