Is the kernel included with Skyraider Athena 1.2 the stock kernel? I've not noticed any improvements with using SetCPU (the clock speed doesn't reduce per my moving the sliders, SetCPU tells me perflock doesn't need disabling) and I was wondering if there needed to be a kernel change of some sort. I saw the Ziggy kernels linked but there was very little about what they included. Can kernels be flashed at will aside from a Nandroid backup (i.e. no need to wipe caches,etc)
Thanks in advance
I Love Ziggy's kernels for their speed and stability. Just be careful, OC past 1190 is dangerous.

I'm looking for battery life w/o too much loss in daily use..Incredikernel seems rated well
The kernel that comes with Skyraider Athena is the stock kernel. I have yet to flash a kernel on top of this rom though.

the reason i want to OC, is for PSXdroid. its too chopping. i have done all the setups required, like disable wifi, GPS, apps in back ground. i am thinking if i OC my phone it will work better.
my setup
incredible 2.2 froyo. root unrevoked, S-off, sense stock.
i have SetCPU installed.
i love sense. i want to keep sense. what is a good kernal with stock sense?
what is it, that i need to OC? just a kernal? or something else?
That is correct. Just an OCing kernel. There's
Hydra Kernels:
hydrakernet.net
KingKlick Kernels:
Look in the Dinc Android Development forum. Titled - CFS #5 / BFS #5.
all i need to do is install one of those kernels?
nothing else?
Install and change settings in SetCPU.
change the setting to what?
It's self-explanatory. Increase the max clock speed = increase performance.
what kernel are you using?
King's BFS #5 flies. Note that o/c too high will result in lag. I recommend setting max @ 113, governer to performance, and that's it!

I know nothing about kernels, so if sense kernels can't do smartass just ignore my ignorance :/
I've checked the kernel thread, but sense kernels seem to be lacking. And the best it seems with multi touch seems to be lou #7

Here's at least another alternative : http://www.ziggy471.com/
Ziggy's support BFS, HAVS, and the older schedulers as well. I don't know about more multi-touch than 2 since my digitizer only supports 2, but the kernel itself supports ~5 I think. I'm using this one:
http://www.ziggy471.com/downloads/ztest-INC-BFS-012111.zip
with my own 'lowered' voltage startup setting script. It is solid, and has the feature(s) I like without wasting too much space on loadable modules, like tunneling, & rndis (wired tether), and all the usual things everyone has. Will overclock & undervolt or (underclock & overvolt) --
I doubt if any kernel actually saves you a lot of battery since that's more likely about everything else, but lower voltage, if it is stable, is perhaps a step in the right direction. It does require a cpu that'll handle it, which is a total crap-shoot.
Hi!
I'm running "HTClay's SuperCM7 Go Go Go! 2.1" and pershoots kernel "2.6.35.13 – OC-UV-NEON_FP" on my Desire Z.
Now before I flashed pershoots kernel, I had extra governors: conservative, interactive, powersave.
Now I only have userspace, ondemand and performance left.
So on towards my Questions:
a) Should I reflash SuperCM7 to get the other Kernel back?
b) Did I just flash a "worse" Kernel?^^
I liked conservative for low battery levels and interactive while charging.
You just have to play around with different kernels to find one that suits your usage style.
In NO WAY is pershoots kernel the worst. Almost every kernel we have is based on his source. All others are CM, which in part, is what pershoot uses for his kernels.
The reason he doesn't put other governors in the is because he feels they're unstable at the higher clocks but he has also stated that you can add those in if you so choose.
Above is correct.. personally I prefer the stock kernal that comes with supercm7, although I only use the on demand governer.... to get it back just reflash the rom...

Quick Update: Followed KCRic Signature link and now I'm happily running UmaroKernel V1.04 - 2.6.35.13 at up to 1.4Ghz
I am currently using MIUI 1.7.29 Osimood with the Tiamat 1.04 kernel, and I am wondering what the best kernel is for battery life. I am also using the V6 supercharger ram script. I am running my CPU at 960mHz at the moment, using the smartass governer. I also undervolted using vipermod, 960MHz at 950mV.
My choice consists of the latest Pershoot, UmaroKernel 1.06 or Tiamat 1.04
What differences would I see between those kernels, are they noticeable for a regular user?
Sorry man, but wehre do you find the vipermod for desire z? http://vipermod.tiamat-dev.com/faq.php it's not compatibile with desire z/g2....
Uh...what's wrong with the kernel it comes with? Can OC to 1.5GHz stock ya know. Battery life is great with it too. People always want to flash something weather it be a radio or a kernel.

Isn't flashing stuff and trying new things basicly the point of this whole site?

damn straight,
1) pershoot is a sense kernel? (i am proabably wrong but i have never tried this kernel)
2) umaro kernel i found had issues with wifi, high underclock freq (leading to poorer battery life), but fun if you have the time to tweak voltages and fast!
3) tiamat kernel i found had issues with sleep of death/random reboots on wakeup couldnt test it past that. (setcpu was set to screen off was: conservative 125min -345 max and would still crash)
if you are up for another kernel, i am now using this kernel (streamline5)
no voltage tweaking (pretweaked) but it has good batt, speedy and stable cant ask for much

Pershoot is actually for non-sense roms. The downfall people have with it is lack of governors. Some don't mind, some want variety. I've had great experiences with Pershoot's kernel and it's the baseline that all others are compared to (not to mention the foundation of almost ALL G2/DZ kernels).
Umaro's just needs to have voltage tweaks done manually but on the plus side - keeping the voltages normal (not UV) allows some people to reach higher OC speeds. It keeps the processor from bottoming out due to insufficient voltage which can easily happen when you UV. The main issue is with the Greased lightening governor - it's new and still a bit buggy.
Tiamat 1.0.4 is outstanding. I can sit all day at 2+ GHz (not literally, see: Chernobyl). I personally have an issue with the interactive governor but other than that it's my favorite kernel (Umaro may take that soon, once greased lightening is perfected).
Basically you just need to try out a few and see which you like. There is no 'best'. Most kernels will work with any ROM (Sense being the only exception).
Bumping a thread that is relevant to my interests.
It's about time for me to jump ship from an outdated CM ROM and try something new like a MIUI ROM.
With that said, I'd like to read more opinions & experiences from people using the various Kernels AND how the latest radio (the one released today) is working for them. I'm just trying to get the optimal experience here
Speaking of MIUI would anyone mind telling me some differences between OsiMood's ROM compared to the official MIUI-US ROM (or even DarkSpadez ROM)?
Thanks a ton guys!
I downloaded the official rom . . .then ignored it downloaded osimood and iv been using it since. Osimood is a lighter rom, which is always a good thing, unwanted languages etc are removed for a smaller faster rom. Also he preinstalls tweaks like an adblocker and extended settings mod.
Kernal wise iv been looking for the same info as you but couldn't find it. So I eneded up trying them all:
- Eugenes streamline5 is a nice kernal, preundervolted. Only probly is its not being updated so will become redundant.
-Tiamats kernal allows over clock to 2ghz and seems to support higher overclocks stably where other kernals can't. Except battery life has decreased with recent kernals
-Umarokernal this is the kernal iv come back to twice and am still on. It allows overclock to 1.9ghz and is kept updated by umaro. Performance per frequency seems as good if not better than most and osimoods miui runs smooth with this kernal on 800ghz with scarey governer (which saves battery) Another plus for me with this kernal is the scarey governer which for me definatly provides the best performance per battery ratio.
I'm currently running MIUI 1.8.5 with Eugene-Streamline 5 Kernel with the latest radio update Vision_Radio_12.57.60.25_26.10.04.12.
SetCPU with Governor ondemand provides me with better usage, power and responsive time then Smartass or Interactive.
OC to 1.2ghz
Battery life, about 30hrs with the regular 1350mah.

i just got 40 hours with similar setup but i use virtuous o/c daemon instead of setcpu
big fan of streamline5 and hope that it will get updated eventually
How do you get the virtuos o/c daemon?

Its basically like an automatic setcpu (which can't be changed on the fly) built into the rom, its in virtuous unity roms
What sleep profiles are you guys usein. I seem to have rebooting issues with any kernel I try unless I go to a sense rom. I've tried the vipermod now to see how it goes
Sent from my T-Mobile G2 using XDA App
But how do you get the virtuos O/C daemon to work on MIUI?
You can download it threw rom manager. Even with that kernel I get reboot issues. I assume its cause system ram isn't being cleard fast enough. I'm gonna try 100mv increase to see if there's a difference.

I'm currently running mik3d and in my opinion its the best 3.0 rom out there at the moment. But what's the benefit of using a kernel other than stock? And any suggestions for kernels and how do I flash a custom kernel? Thanks in advance
Sent from my PC36100 using XDA App
I am running MikG (not 3D) but I can address the reasons for running a custom kernel.
- Overclocking: Custom kernels will often allow you to change the max cpu clock to improve performance when you need it.
- Underclock: They also allow you to lower the max clock and the min clock if your aim is to try and improve battery life.
- More Governors to choose from: They will often have other cpu clock governors that can be used to balance battery life vs performance (see here).
- Undervolting: Some kernels will use various schemes to undervolt the CPU as another means to save power.
- HDMI Mirroring: The stock kernel will output a display to the HDMI only from the photo gallery app. The custom kernels can allow full display mirroring to the HDMI. This allows games, netflix, etc to be viewed on the big screen.
- Memory optimizations
There may be more reasons... these are the one from the top of my head.
You flash a kernel much the same way as you do a ROM. From Recovery you would wipe Cache and Dalvik Cache before flashing the ZIP of the kernel. That is it. Some kernels then allow adjustment with programs such as SetCPU.
There are a few kernels that support Gingerbread Sense roms (such as Mik 3D). You can look at Freedom, ChopSuey, Golden Monkey, Poonsense. I am running Freedom and it works well for me.
I just tried adjusting my CPU after installing freedom and my phone froze lol

Some phones do not like to be overclocked. That is normal. You just have to find out what your limits are. Mine actually does not like to be run as low as 128Mhz. When I do that I get boot loops once in a while.
