[APP] NovaFreq v1.2.1 (For Novatek Panels Only) [ Updated 07/18/10 ]

Evo Switch v1.1.1 NovaFreq v1.2.1
(APP NAME CHANGED TO SOMETHING MORE APPROPRIATE)
This is an Android application developed to change the panel frequency for Novatek Panels for the Sprint HTC EVO 4G, in conjunction with ffolkes' Novatek Kernel and netarchy's Kernel,
and any kernel that has maejrep's T2 Interface built in. Every device is different, and with that, those specified kernel's default settings may or may not be optimized with your device.
With this application, you can change those settings on the fly and find the best setting for your device.
[ Please use this application with extreme caution! I am not responsible for any damage this may cause to your device. ]
Requirements:
-HTC EVO 4G
-Android 2.1 +
-Any custom kernel that is built off of toastcfh's htc source
-Novatek Panel
-Root Access
Uses:
-Use as an fps frequency turbo switch for when you need extra fps.
-Use as a debugging tool to test frequencies.
-Use to keep frequency settings even beyond reboots. (new)
Settings:
-340 [Stock] is how HTC intended the EVO to be. This frequency works out to 61hz, but we are capped at 30hz.
-370 [Kernel Default] sets the panel frequency lower than stock, yet provides most around 55fps.
-250 [Stable High Freq] sets the panel frequency higher than stock, which usually gives around 40fps.
-400 [Stable Low Freq] - V2's setting.
-Favorite Setting - Find the most stable setting, and if it's not one of the listed, then "Set Favorite".
-Sticky Settings - Now you can reboot and not have to re-apply your settings!
Custom Setting:
You can put arbitrary settings here, but be warned this may mess up your screen, but usually you can reboot your phone
to change it back to default. Minimum Recommended: 250 Maximum Recommended: 999.
Please do not go lower then the minimum recommended of 250, nor higher than the maximum recommended 999.
To Do:
-Favorite Setting - So you can save the best setting for your device. 07/04/10 - Done!
Change Log:
-Changed app name from Evo Switch to NovaFreq (Novatek Frequency / Freek)
-Totally redid code, should be more optimized.
-Frequencies stick beyond a reboot
-Changed a few of the defaults
-Changed back sleep time to 500ms so the current displayed setting can update (v1.2.1)
Don't be alarmed if you see NovaFreq running in the background. To be able to sticky settings beyond a reboot, NovaFreq has to be run at boot up.
After that you can kill NovaFreq if you want, android will kill it when needed so don't worry.
Thanks To:
ffolkes, netarchy, maejrep, toastcfh, halfline, Cicitrize, geyes30, kpkimmel, joeykrim, and many others involved in trying to uncap the EVO.

Reserved...

Reserved again.

woah, this is badass. I will check it out soon

works great! Whats the number I set it at to equal the V2 setting of ffolkes kernel? I think its 400, is that correct?

Awesome!! This is the first time I've been able to break 30 fps! (thanks to your app!)
I'm on Froyo and the v4 had never worked, but now v4 + high frequency with your app = 40 fps.
I love you.

this may a silly question... but would this fix camera when i have it disabled as to if i switch it on the camera is now broke? or just the kernel itself breaks the camera??

Great little app, I would recommend users experiment with the values just ever so slightly for optimum performance. Using the default value of 361 netted me about 50-51 fps, whereas using 365 nets me about 54-55. Not a huge bump, but even a little bit is nice

Great application. May I suggest adding maybe a quick cycle to move between frequencies so users can go through a number of settings at once? Kinda like the Scan feature in most radios to pick the best frequencies.

Every custom kernel does not have a working camera, because we do not have the source code for it. When HTC finally releases the source code, then we will be able to fix the camera.

This sounds like something to think about. Only problem is, while scanning, no one will know what the fps is unless they have their favorite fps app running, but then we wouldn't know what the frequency setting is since the fps app is running in focus. Might be a bit difficult to pull off without building an fps test into the app.

Well done!! Thanks

Yeah I agree it would be difficult to implement without a built in fps counter. I was thinking more along the lines of something that would flag or eliminate the frequencies that are really bad (ie the ones which make your screen go haywire). So maybe the user could, for example, pick frequencies 300-310 and then the app would cycle through them 1 second at a time. From there the user would be able to run FPS2D or whatever to test out those frequencies that didn't make their screen all blotchy.
Anyways, just something to think about. Great work nonetheless!

This won't work, because the interface that is used to write these settings to the panel cannot handle both full-speed graphics, and setting panel registers. I tried this when I first created the sysfs attr file, and if fps2d is running, it seems impossible to set or query the current T2 value. the display pretty much has to be idle for this to work.
Using a mutex lock might help, but I didn't look into it any further.

Yep, that's why I had to put in a "sleep" command in my app so that the system could process the change and update the app on if the register changed or not. Thanks for the interface maejrep!

Do you meet the minimal requirements on the original post? Because you have to be running a custom kernel with the T2 interface in it.

[Discussion] Ways to improve UI response on Android

Given the recent hoopla in the blogosphere about how iOS places higher priority on User Interface actions than Android. I was wondering what ideas can be implemented in current Android or Linux kernels to get better UI response.
Overclocking or upgrading to a faster phone is the brute force way, a smarter way would be to give higher priority to user input instead of benchmark/multitasking score numbers. I think it makes sense to give the User input highest priority because in computation timeframes, user input is rare, and considering how important smoothness affects overall perception & enjoyment of a device, it's a good idea to allow other OS background tasks to take a backseat when the User wants to do something.
I'll start the discussion with two ideas I've implemented in a kernel recently that has shown improvements in UI response.
1. Switched to using SIO (Simple IO) scheduler (similar, but slightly lower benchmarks than Noop). Main difference is SIO prevents the system from hogging resources when large amounts of data needs to be read/written. It has a timeout so UI threads has a chance to run also.
2. Switched the touchscreen driver interrupt service request from using the general events workqueue (schedule_work()) to a dedicated workqueue (queue_work()). Touchscreen generated actions get to ride in the fast lane.
Any other ideas people have?

http://blog.crazybob.org/2011/12/truth-about-android-ios-ui-performance.html

the thing is i may be using a note but when using ICS with apps that are updated for ICS, i feel its smooth enough. the real difference is i think ios uses completely different method for scrolling i.e. the bounce function and slight delay in finger recognition. same with ios touch recognition, it just somehow is better no doubt.
btw when i was miui with bounce it definitely felt smoother but although it wasnt ios smooth.

The main difference between ios and android is the fact they use ram in two totally different ways. Ios handles ram in a manner to make the user interface smooth as possible all the time while android frees ram to make multitasking better. The problem that android has is changing the way android handles ram to make the interface smoother for the user. They wont be able to for a long time because they have to do a total overhaul on the whole dalvik cache type setup that android uses.

i recently started using supercharger v6 which messes around with the ram and how it should be allocated for desired operations. I don't know if it's relevant but do you think it makes a difference and which setting would get you a better scrolling experience?

I liked the supercharger when I used the Droid Eris but since I've upgraded I get more redraws than without it. I used the 768hp I think.

you could edit the ramdisk to set more of a priority to rosie.apk or whatever launcher you use...just a thought

That would be the same as locking home in memory.

There are a number of issues that contribute to a "sluggish experience". The supercharger v6 script mainly keeps more memory free so that switching to new apps cuts down on the garbage cleanup of older apps. One of the downsides I've noticed with more aggressive lowmemkiller settings is a lot of apps get killed in the background when they need to stay for when users want to multitask.
The hardware acceleration route has downsides too from what I've heard, it requires more RAM per app just to have it enabled.
One of the articles posted earlier has good insight. Mainly because a lot of apps share a general events queue, and developers should not have a lot of blocking code in there, but developers make mistakes. The tools available for Android to develop and tweak UI performance seems lacking at this point.

How about SIGSTOPping everything else when you touch?

does it work with samsung i9000?

Supercharger?
Sent from my Sabotaged Droid Incredible 2.

I find that either turning off cpufreq (by using the Performance governor) or increasing the lower frequency makes things a bit more snappy. For most governors, there's a delay between CPU load and the frequency being increased. This delay is usually noticeable if the CPU load is due to me working with the interface. By increasing the min frequency to, say 800mhz on a Nexus S, this makes things a lot more snappy than the default setting of 200mhz.
Another thing that helps with the smoothness (at least for me, in ICS) is the setting that forces GPU acceleration for all apps. For example, apps these days (well twitter and Facebook) have that pull down to refresh widget from iOS. Without forcing GPU acceleration, the rotating arrow animation usually hitches quite a bit, but is smoothed out with this setting on. This setting can be found in the developer options in the settings.
Hope these help,

Turning up the min CPU can cause freezes on some peoples phone though and using the performance governor can drain the battery quick. The reason the CPU scales up the way it does before it gets to max frequency is to save battery.

System tuner pro has alot of tweaking options that on memory use
those that use launcher pro can find a memory usage setting in launcher pro to.

Agreed, but the whole point here was to help improve UI responsiveness. Without rearchitecting the OS, a good way is to allow the CPU (which is busy sharing its resources with non-UI work) to react more quickly is to ensure the CPU is at a higher clock rate before the UI needs it.
As for battery life, it really depends on your usage pattern. If you have a lot of background processing going on, preventing the CPU from going to sleep when idle, you may be better off scaling back the minimum cpufreq frequently. If your CPU actually goes to sleep, give scaling things up a try. A handy tool you can use to see how often the CPU is sleeping is CPU Spy. To see which apps are keeping the CPU awake, there's a program called Better Battery Stats available on XDA and market.
As for stability, I don't mean over clocking the CPU...all I'm suggesting is to increase the frequency the CPU goes to when the screen is on, but nothing much is happening. This should still keep things within safe limits.
Hope this helps,
- chris

I find the interactive governor does a very good job of ramping to max right from idle (instead of waiting even a few ms like ondemand does). It assumes coming out of idle the CPU is starved. Then scales back once demand lowers. No fancy locking to min freq when screen is off (which can stutter some background apps).

There is many thing what can be done in the code of the applications. For example once I had a really sluggish app. It turned out that while I was dragging an item in the UI, the UI needed to be relayouted, and the draw calls were simply postponed: in android (at least that was the case before ICS) the drawing of the UI is delayed while the UI thread is too busy with events and layout requests.
To find these issues it's really useful to use traceview.

Overclocking Transformer TF101

Hello world,
I am wondering what program you guys use to overclock your tablet? Or what procedure? I am currently at ARHD rom with ICS test 21.3 kernel and am wondering what clocks do you guys use - suggest also some UV list would be great
thanx
make love,
miHah

apps to control cpu speed
use: set cpu (paid) or nstools (free)

Ok, what about schedulers? I installed setcpu and its on "sio" ondefault. Which one to use and when?

I don't like setcpu, or any app to oc for that matter. When I was on ARHD (and therefore had to use an app) I used No-frills CPU control, not too many bells and whistles and worked.
I highly recommend 'interactive' for a performance governor, it's easier on the battery life than performance and snappy.
Default scheduler with wifi off during sleep tweaks is fine.
I use 1.4 Clock at home and 1.2 out and about, but you can probably go higher if you want, 1.2/4 is plenty fine for me though. (I keep my RAM really free though, I feel that is more important. IMO)

[Q] Optimal cm9 performance settings?

Hello everyone,
I've been using the cm9 release candidate since it was released, and still can't figure out how to make it snappy (I was on Apex before, and found it much more responsive). I'm not sure which the performance/memory management settings the Nexus S can handle well (there are lots of other threads for other phones, but I'm not sure if some of the settings require better hardware), so I'd appreciate it if anybody could tell me what they've found to be good for the following options:
Performance settings:
- Surface dithering
- 16bit transparency
Memory management:
- Allow purging of assets
- Kernel samepage merging
Misc. information that may or may not be relevant:
- Using Matr1x kernel (CFS, v21.0 I think)
- Processor is running at 200/1200 most of the time, ondemand governor (same settings that used to give me great performance on Apex).
- Also tried running Supercharger script, but it didn't seem to change things as much as it usually does
- Fixing permissions didn't fix it
- Battery life seems fine
- What I mean by "unresponsive" is that the launcher takes longer than usual to redraw and is laggy switching between windows, apps often force close or take forever to start up, and the browser reacts much more slowly to pinches, swipes, etc.
Thanks!
tl;dr: CM9 users, please share your performance + memory management settings. Explanations not required, though appreciated.

You don't need to mess with those settings.
Besides, if your applications FC, it's likely because of:
a) instability regarding your overclock
b) instability regarding the undervolt that matr1x kernel comes with
c) the fact v21 was canned due to being judged unstable by so many, upgrade to v22
d) all of these
Cheers

If you don't know what a setting does, don't change it. Messing with the CM performance settings if you don't know what you're doing is a great way to mess your phone up.

are you completly retarded? there doesnt happen much when you change the settings there. you are talking like the settings are just for pros and he is a kid, lol. kernel samepage merging for example just "bonding" two similiar proccesses so they dont need too much ram.

[Q] Cpu/Kernel Manager Suggestions?

Hey guys. First off, Apologies if this has been created or discussed before. I have searched before this posting; as I am not big on creating new threads, and the stigma related.
Anyway, On my HTC EVO 3D, I used Kernel Manager, as it had a great layout, allowed cpu/gpu adjustments, AMAZING widget, mpdecision support, ThermalD suppport (I do know the support comes from the kernel, Im saying the app allowed me to customize it), set vsync, color depth, whole nine yards. Im looking for something like it that would work well with the Infinity. Ive noticed kernel manager and ROM Toolbox are both finnicky with the tablet and it doesnt do as well. Kernel tuner works best, still it seems to not get along with the extra 2 CPUS. their governors always revert, it wont display CPU temp properly, no GPU settings, The battery drain is always +/-errmA (i guess error Milliamps) and the widget only displays two of the four CPUS. Anybody have any suggestions, or a solution to make kernel tuner work? Anything is welcomed and appreciated. Thanks in advance.
