Only just started using Franco Kernel on my N7 again since early r40's. Feels much better now.

Just a quick question for those who game on their N7s. Do you guys oc the gpu? If so by how much? I do all my android gaming on my n7 and battery isn't an issue.

Also would anyone have any other suggestions to eek a bit more gaming peforance out? I know the defaults are often the best but any changes for gaming specifically?

Thanks.
[Nexus 7 Original Development] poondog:
HEY AN AUSSIE, Gday!

I OC mine to max 484MHz, I don't see much difference between 484 and 512. I don't go above that though :P The games I play are Bloons TD 5 :D, shadowgun DZ, real racing 3.

One thing I can say with r58 (I think r50+) is that the kernel sometimes drops randomly to 102MHz (I am on interactive). If this problem occurs to you I would change the lowest frequency to 475MHz, I do this when watching videos and playing games and I get no lag or dropped framerates.
[Nexus 7 Original Development] Bobtehblob:
Oath! I'll give that a go, thanks! :) Is there any need to change voltages at all or will stock levels be fine?
[Nexus 7 Original Development] poondog:
I drop all my voltages so they're 125mv less than stock, but I dunno if it works or its placebo because the voltage has been confirmed working and not working lol

If you read the past few pages though there's discussion about the new hotplug driver and squeezing performance and battery out of the device. The default governor ondemand imo is more battery heavy than interactive using our 'winning' tunables
[Nexus 7 Original Development] The Gingerbread Man:
FYI 520 is better than 512. Metalalice and Osmosis were having a discussion about it in this thread mid January time if you go back there's lots of good information.
[Nexus 7 Original Development] Bobtehblob:
Okay so i've done a few races in RR3/general use with GPU OC at 520, minimum CPU freq at 475. Feels great, will see how it treats the battery life over the next couple days!

There is absolutely no way the UV is working though surely? You put everything on 575mv and it doesn't crash?
[Nexus 7 Original Development] poondog:
Apparently there is a safety feature in the kernel that doesn't let you undervolt too much. That's probably why it stays stable

For everything other than games though I'd change the minimum freq back to 102
[Nexus 7 Original Development] Gspin96:
The "lock" is at less than 600mV. So, if I set the voltage for 1300MHz at 625mV it should work and immediately crash the device. But it doesn't.

But now the governor-freeze problem looks more important than this IMHO.

PS: I'm back to the stock cyanogenmod kernel and... hell, it seems much smoother than this in any non-game purpose (i can't mention games as this kernel allows GPU OC). I don't think it's placebo because when I flashed that kernel, I didn't know I had forgotten to re-flash franco.kernel after the CM update :silly:
[Nexus 7 Original Development] Bobtehblob:
Okay so basically it's impossible to crash the device by undervolting too much? Just then I ran Antutu stability tests from -50mv to -300mv with it passing everytime. How are people finding safe values for their device then? On the N4 I would go -25mv lower each time, running a stability test to ensure it was stable. Eventually settling on -125mv.
[Nexus 7 Original Development] osm0sis:
What they were saying is it's impossible to crash because UV isn't working. So don't bother. ;)

Gspin's explained it perfectly :good:
[Nexus 7 Original Development] Bobtehblob:
Oh f***. Well that was a waste of time! The more you know I guess ;)
[Nexus 7 Original Development] Bobtehblob:
Just had a huge slowdown. Only one core online, stuck at 102 mhz. Alternating Governors caused it to normalise.

View attachment 1905619
[Nexus 7 Original Development] osm0sis:
Yup. That's the bug in a nutshell. Either a fault in the hotplug driver, or interactive (..and ondemand too ;)) somehow not playing well with the stock freq steps and the new hotplug. Honestly, I continue to believe that since it wasn't a problem with the other hotplug drivers we've been on that the answer should be obvious, but what do I know. :p
[Nexus 7 Original Development] poondog:
Easy fix: turn screen off and on again :)
[Nexus 7 Original Development] Warren_Orange:
Hi Guys.

I had a problem with the latest Franco that came bundled with Smoothrom for the Nexus 7. I think it was Franco r58. I had a total hard lock while I was browsing. Everything froze and the N7 was not responding. I had to hard reset the N7.

I was not using any CPU clocking programs. I reinstalled Smooth again and used Motley, but I would like to go back to Franco as it was damn fast. I am currently using Franco r47, but would like to try r58 again.

Should I get a CPU clocking program and try and set the min cpu to something higher?

Cheers.
[Nexus 7 Original Development] MaNFr3:
Try to set with franco kernel app min cpu freq tu 340MHz I solved with this tune. I was loocking cpu & usages with trickstermod using every stock and I was seeing 340Mhz step was normally used when screen is on.
[Nexus 7 Original Development] osm0sis:
There is no 340 step. So you must mean 475? Yes that is the only actual workaround we've found for the issue.
[Nexus 7 Original Development] Warren_Orange:
Thanks guys.

So what clocking app should I get? Franco?

Cheers.
[Nexus 7 Original Development] Shano56:
Get francos app for awesome kernel control and to support the awesome dev! It costs less than an average meal!
[Nexus 7 Original Development] Warren_Orange:
Will I take a hit on battery life?
[Nexus 7 Original Development] Shmi117:
I haven't had one lockup ever since installing r58.

My specs:

- 1000 max freq

- 102 min freq

- Conservative governor

- Stock GPU frequency

- UV by -100 (This is broken still so doesn't matter)

No YouTube stuttering, no lockups, smooth in my opinion. My last Android device before getting the Nexus 7 was a GS2 T989 (Hercules) so my standards are pretty low when it comes to lag. I'm getting insane battery life too because of my low standards.
[Nexus 7 Original Development] maarawoe:
Not sure if its kernel or rom related (parandroid) but youtube videos doesn't start (even on 400 mhz min) and playstore downloads are not starting as well...

I am running r58.

Other devices on the same network are ok - this is purly nexus issue...

Thanks for any advice!

Edit: no issue on r47
[Nexus 7 Original Development] c0x91:
Wich app did you use to set the kernel?

Inviato dal mio Nexus 7 con Tapatalk 2
[Nexus 7 Original Development] Shmi117:
I always use Trickster Mod for all kernels.
[Nexus 7 Original Development] osm0sis:
Well yeah. :silly:;)
[Nexus 7 Original Development] Warren_Orange:
:o

Bit of a silly question wasn't it he he.

I've been running r58 all afternoon with smooth ROM and do f far no lock up. Everything is great.

If have any issues I will try the 475 min CPU.
[Nexus 7 Original Development] khaytsus:
Anyone use Tasker to control CPU settings? I'd love to throttle some games I play as they seem to use a ton of battery but Tasker does not appear to be doing anything. I set it to change max CPU on cores 0 and 1, can't set 2 and 3 without them being online apparently.

Any suggestions? I could manually do it but that's tedious.
[Nexus 7 Original Development] hasenbein1966:
I would like to change my kernel to Franco (using Motley up to now).

But I need NFS filesystem capability. This is not included in Franco, right?

My question: Is it possible to use some kind of kernel module with Franco to add the NFS?

And is there somewhere a download for such a module? (SmoothROM 5.1, Android 4.2.2.)

Thanks,

Hasenbein
[Nexus 7 Original Development] nexusmaniac:
Thanks

Thanks for the settings, I've started to use them now and there has been no YouTube stuttering and no lockups :)
[Nexus 7 Original Development] slybunda:
NFS or NTFS?
[Nexus 7 Original Development] osm0sis:
He said file system so he must mean NTFS.
[Nexus 7 Original Development] hasenbein1966:
Nooooo. NFS. N - F - S. :silly:

I'm not a noob! Of course I know that NTFS is no problem... :cyclops:

NFS

is

a file system - the Linux network filesystem. It's needed for mounting network shares into the local file system - just like CIFS, but quicker and "native".

If you open the file /proc/filesystems with a text editor, then, if NFS is supported by the running OS, there should be a line with "nfs" in this file.

There are CIFS and NFS modules for other devices and kernels, but I can't find anything for the Nexus 7 with Franco kernel. (Motley has NFS built in, so I use it up to now, but I read that Franco has best performance and battery, and I want to try it, but not lose the ability to mount my NFS share with media files on it.)

I hope now my question is clearly understood, and I hope to get answers from people who have a clue. Thanks!
[Nexus 7 Original Development] osm0sis:
Hahaha ok. I'm not familiar with NFS so thought sly was being cheeky about Need For Speed or something. :laugh:

My best guess is you need to hunt down the module. Steal it from Motley's zip/ramdisk maybe?
[Nexus 7 Original Development] hasenbein1966:
No, in Motley it's baked in in the kernel...

A Google search "nexus 7 nfs.ko" (nfs.ko is the name of the nfs module) gives nothing...
[Nexus 7 Original Development] khaytsus:
$randomkernel NFS module isn't going to do you any good. Perhaps Franco can just enable the module in his config, he probably just never has been asked or needed it.
[Nexus 7 Original Development] nexusmaniac:
Is anyone else having battery problems with r58? The battery for me has stopped lasting as long since r57.
[Nexus 7 Original Development] osm0sis:
One word: ondemand.
[Nexus 7 Original Development] nexusmaniac:
Oh the duh I completely forgot about that :rolleyes: thanks :)
[Nexus 7 Original Development] LeoNg628:
Hi Franco, does your awesome Kernel support tilapia?:confused::o I have bootloop on my tilapia after flash this, am I did wrong things?...:crying:
[Nexus 7 Original Development] nazz.rule:
It works fine with my tilapia. Maybe you should flash this kernel via fastboot.
[Nexus 7 Original Development] android1999:
Sorry if I am asking a noobious question but does Jay's buttery tweaks work with this kernel. Please don't kill/flame me. Sorry again.
[Nexus 7 Original Development] ÜBER™:
Those tweaks are useless.. sorry. All you need is this kernel. ;)
[Nexus 7 Original Development] android1999:
Well that's what you think trust me I have used the kernel a lot. Currently I am using m kernel because of its support for those tweaks. You can run an androbench benchmark before and after those tweaks to just see the improvement in io performance.
[Nexus 7 Original Development] ÜBER™:
Really.. benchmarks tell me my device is smooth? So just because you get "higher" numbers it makes the device faster? :rolleyes: Those tweaks are worthless.. trust me

zRam is useless for newer devices.. it used to be needed with devices with less than 512MB of RAM... we have a GB.. its not needed.

Remounting /data and /cache can be triggered with a command.. ive never seen any point in this.. all it does is boost I/O in Quadrant..

And you can disable fsync with the command in the second post or with francos app.. or with trickster. This is where you get the higher read and write speeds.
[Nexus 7 Original Development] osm0sis:
The noauto_da_alloc mount option is already in the fstab too, if I'm not mistaken.
[Nexus 7 Original Development] The Gingerbread Man:
how's this for an improvement for io
[Nexus 7 Original Development] bjcrj:
Both m-kernel and Franco's kernel already include the remount tweaks in their ramdisks. Uber is right, with Franco an m-kernel the buttery goodness script is useless.
[Nexus 7 Original Development] jazzespresso:
Hi all,

I have been following this forum last several days. There are over 500 posts and a lot of information to digest.

and I have seen that several people making adjustments after they flash franco's kernel. I bought Franco's app (paid one, to help developer) way back, and now I am wondering if I flash Franco's kernel, and leave all settings to default, but I have still some concerns about it.

it seems like some people having some youtube issue, or playing high cpu intensive games...etc..

considering I am not experienced kernel debugger nor kernel developer, considering all I want is better kernel than stock one, should I go head flash Franco's latest kernel and leave all default settings?

as always, I do very much appreciated if some of you can provide some feedback or suggestions. I am pretty sure there are many people who come here in this forum and reading thru all 500 posts would probably got in lost too, like myself.:confused:

bunch of thanks in advance
[Nexus 7 Original Development] k29er:
I tried r58 a couple times, ie: every time someone post what they think is a fix. I found if I flash the kernel but don't install f.Ku or any other kernel control app it only stutters after a pause when streaming but eventually starts playing smooth again. Changing to Westwood was also suggested and worked with r57 but I didn't try it with r58. I am getting just as good performance and better battery life with the kernels most custom ROMs come with now and only flash/play with custom kernels to try them. Not finding much need for them any more.
[Nexus 7 Original Development] timbck2:
The consensus for now seems to be to flash r58 and if you experience any stuttering in streaming video, increase your minimum CPU speed to the 475MHz step.

[Nexus 7 Original Development] osm0sis:
Franco only updated f.Ku for N7 changelogs with r57 so outside of this thread he wasn't keeping track before.
[Nexus 7 Original Development] Metallice:
since when? All relevant tweaks have been included in ramdisk since forever and zRAM has always been worthless.

And all of this applies to Franco Kernel as well.
[Nexus 7 Original Development] konradsa:
My observations: I have been trying out the latest kernels from Metallice and faux123, and it seems to me they are smoother than the Franco kernel (I tried r58 and r47) even at stock speed. Overall, they seem faster and less lag, don't know about the battery though. Anybody else had the same experience?
[Nexus 7 Original Development] The Gingerbread Man:
Any chance you might be able to name a few examples of particular apps or anything specific?
[Nexus 7 Original Development] ktkr:
Per my experience the performance of the three kernels are similar, while Franco's new hotplug still has some minor issues to be fixed. They use different governors so your experience may be caused by the governors.

Currently "Nice" ones of the three IMO are v17 of faux and a53 of m-kernel, I expect to see the fine tuned version of Franco soon, although the glitches of the current version can be somehow fixed by lifting the minimum cpu to 475mhz.
[Nexus 7 Original Development] nexusmaniac:
I changed the governor to interactive and set minimum frequency to 475MHz and I've had no YouTube stuttering or any other lag so far also the battery life is great unlike with ondemand :)

I wish some other experienced users and developers (like; Metallice & osm0sis) also post their settings too. like xiFI said "i want good battery life, but also decent performance when i need it?", that's exactly what I am looking for too.

[Nexus 7 Original Development] The Gingerbread Man:
To noobs or people who aren't sure or don't understand what everything does leave these turned on. Fsync off will boost your benchmarks score but if you have a random reboot there's a good chance it could **** up your apps or settings or both and loose data, saved games and all sorts or screw your titanium back ups. The loggers are helpful in debugging when you do find an issue with something. Uber I know you know what your doing but just a warning for others, particularly the inexperienced guys.

Surprisingly I've never had any data corrupt on me with fsync off. Is there a higher chance, yes... But its not entirely likely to occur unless you under volt to an extreme extent. Most I've had happen is my launcher setup freak out. But nothing else. But I understand the intention.

I can understand why people would run with it off, the difference is IO benchmarks is incredible I just think it is a little risky, good job undervolting is broken so to minimise everyone claiming the kernel screwed their **** up lol
