[ROM-DEV] 04/27/10 | Fresh Toast v1.1 | BFS + Full Scaling Overclock + EXT4/a2sd Fix

Geek 4 Me is proud to release
Fresh Toast v1.1 by toastcfh and flipz
First off let me remind everyone that this is a dev rom. Meaning it is a proof of concept type rom and is NOT going to be fully functional. This is built on the .27 kernel which means no camera and no light sensor (causing bottom lights to not come on). With that said...!
New features in 1.1:
Full scaling overclocking. You can now use setcpu to set the speed. Anywhere from 245mhz to 767mhz - toast. Thanks to phh and maejrep for their help. Download setcpu from the market for $1 or free here. Note: When you set it up and asks for device, scroll all the way to the bottom and pick custom!
BFS (Brain **** Scheduler) version 316 has been added and customized. This dramatically reduces latency on the phone. While it doesn't increase benchmarks it will really increase the usability and smoothness of the phone. Go here to learn more. -- toast. Thanks to maejrep for help.
Fixed apps2sd and ext4 not working together
Removed AutoKiller. It will likely still show up on peoples phones because it's on your /data/ partition but I decided to remove it after I realized it was reporting location and who knows what else. I already created a modified version that leaves the ads for the developers sake but strips the Flurry reporting however it's not playing nicely with installing. I'll get an update.zip posted when I figure out it's problem. -- flipz
Found and fixed a bug in HTC/Sprints code that was causing 99% cpu usage, draining battery, and causing overall slowness. This bug doesn't seem to affect everyone however it was affecting me big time. It exists in every Sprint 2.1 RUU based build. --flipz
Features:
Custom kernel -- toast
OVERCLOCKED to 767mhz -- toast, with help from phh and madcoder
Compcache and ramzswap enabled -- toast and flipz (? and ? if you don't know what they are. **read warning below)
Ext4 support -- toast (has many benefits over ext3. ? for more info)
Fixed vanilla lock screen (including airplane mode/emergency call glitch) -- flipz
Some modified artwork (toolbar and selector, because toast loves it) -- flipz
Newest autokiller (more info on this app: http://geekfor.me/faq/autokiller)
Disabled home screen menu from popping up when using menu button to unlock --flipz ( patch to disable menu to unlock if you prefer: http://geekfor.me/fixes/bugfixes-requests-lock-screens)
Uses Fresh Rom 2.0d as it's base so all other fresh rom features are in here -- flipz
Not working:
Camera
Light sensor (causing bottom lights to not come on)
Please don't ask when these will be fixed. The short answer is they require the new kernel to work on Android 2.1, however we can't enable all these cool features on the new kernel until we get the source from HTC... again. But as always, toast is working on fixes. So buy him some coffee.
Compcache/ramzswap questions:
How do I make it work? Your sdcard must be partitioned with a swap partition. Most anyone running apps2sd will have this already. Other than that it's automated.
How do I know if it's working? Open an adb shell and type in "free". If you have "swap" listed with any numbers next to it, it's working.
What is required to run it? A class 6 sdcard is highly recommended for speed and stability
How do I disable it? Just delete or rename the script at /system/etc/init.d/compcache.sh to anything else and reboot
**Will this wear out my sdcard? Just like apps2sd, ramzswap puts extra strain on your sdcard. If you are using a decent sdcard then it shouldn't be a problem. Many professional grade HD video cameras use sdcards as their medium, and they don't burn out. If you are using a low quality card then this may cause it to prematurely fail. Do not blame us. You have been warned!
Overclocking questions:
How do I know if it's working? This is hard to prove, other than to say you can run benchmarks and clearly see it. Any CPU applications (including setcpu and OC widget) are going to continue to report the stock speed of 528mhz. Full scaling IS coming soon which will allow you to select the correct max speed.
Will this hurt my phone? Toast and I have been running this for days with no ill effects, even when stress tested for hours. There were no crashes, no errors, and no significant heat gains. However, like always, you are doing this at your own risk and we can't be held responsible.
Do I need to use setcpu/oc widget? They will provide you 0 benefit. The phone has HTC's power manager enabled which means it will throttle up the CPU when it's needed, and throttle it down when it's not. As mentioned above, full scaling is coming soon which will allow you to adjust the speed through those apps if you choose.
Make sure you are using a temperature monitor if you are overclocking and watch your temps.
How do I flash this rom?
It is very likely that you can flash this rom on top of Fresh 2.0d without a wipe and have it work without any issues, however the following procedure would be recommended (assuming you have a class 6 sdcard).
Boot in to RA and do data wipe
Format your sdcard with 32mb swap, 512-1gb ext2, and the rest fat32
Convert ext2 to ext3, and then ext3 to ext4
Flash the rom and reboot

No, sorry about the confusion. Just meaning it has the working vanilla lock screen including the fix where the emergency call button would show up after being in airplane mode. And no it's not AOSP, it's based off of fresh rom. It says that.
Goodnight all!

It does seem faster especially in sense

Love it and you all, in a very manly way!

You guys are bad ass, flashing now. Thank you!

How's battery life?

Yeah the question above me ^^^^^^^

Try it and see?
Technically battery life should be about the same as whatever you're getting now. The speed increase is 'on demand' so unless you spend all day doing cpu intensive tasks (and no, phone calls aren't cpu intensive ) you should be fine.
I'm going to wait for the .29 kernel source to be released before I play with this. Unfortunately I need my camera.

Nice! Would you mind sharing your settings/setup? You are currently kicking my phone's trash.

Trying it just to give it a shot but not keeping it till I get a class 6 card. Noone in my area sells them. Max is 4 atm. Hate living in an area where technology can only be acquired online.

Thanks, just bought your app!

This app looks promising! Thanks

Does the free app support Dual Cores ?
It doesn't show anything like No. of Cores on My Optimus 2X.

According to the market description it says it does support dual core devices.
The paid version definitely supports dual cores as I use it on my LG O2X and nicely shows two graphs for each core.
I just can't activate CPU Frequency on the O2X with CM7 #81 + vorkKernel. It works fine on my N1 with MIUI 1.7.15.

Thank you to everyone for your support! I really appreciate it
The free version supports dual cores but doesn't display any core information as you have said. Only the paid version supports core details, different statusbar notification colors, and CPU frequency (on supported devices). Hope this helps.

Bought the paid version, but is only detecting 1 core on my Droid 3.
Will you be providing support for this phone? (TI OMAP 4430 CPU)
EDIT: nevermind -- it's working as intended when the second core kicks in. Missed that disclaimer before somehow. Thanks for the app!

CPU frequency reporting does not seem to work on OMAP3, or the Nook Color+CM7 at the very least. I was disappointed to find this out, and returned the app.

Nice, It would help to show the % of CPU use in the activity too. (per core, and total)

Thanks for the feedback. I've added your request to my notes and will try to get this implemented in a future release.

I'm sorry to hear this but its something that is out of my control. Some devices just don't allow for reading that data.

I bought the paid version, but I have a question:
****** NOTE ******
HTC Sensation Owners
There is a device limitation with reading the CPU Frequency. I am looking into a workaround for this problem.
****** NOTE ******
Click to expand...
Click to collapse
I have a Sensation, what do you mean exactly here? that the frequency displayed is wrong? Or that it reads the fre for only one of the two cores?
And my most important question : despite what is above, can I trust the app when it shows only one core running or two cores running? I mean, can I trust it to see when the second core starts running?
That's what matters for me, with this asynchrone dual core, the possibility to know when the second core starts running
(and if you tell me "yes", I will be disappointed by the Sensation, your app shows the second core easily starts running, when I was sure it was not and thus explaining the poor benchmarks of the Sensation)

A single core will only run if it is needed, for example when you have two separate programs running. a single app that has not been optimized for using both cores of a dual core cpu will always just use one core just like on a single core phone.
It's the same as on PCs. If there is no optimization to use all cores it will just use one. Dual core doesn't mean that a single process will automatically be split into two separate processes for each core. Your Sensation being slow can have dozen different reasons.

But the OS itself is multi-core aware and it does run multiple processes simultaneously -- are you saying that they'll all run on the same core even when that core is taxed?

No, I was trying to say that a single process won't be split into separate processes for each core if it is not optimized for multi threading. That's what I know.
As you said multiple processes will surely use all the CPU's power, meaning both cores.

Notication ?
WTF is that ?
Notification you mean ?

Not exact: there are two kinds of dual core on Android smartphones:
=> Tegra 2 platform: the 2 cores always run simultaneously, at the same speed.
=>Qualcomm platform: this one is asynchrone and works as you said, only one may work, cores can work at different speed, etc
Android 2.3 is not supposed to handle Qualcomm asynchrone dual core, so that's why I want to know if this app can be trusted concerning the usage of asynchrone dual cores.....

Okay, thanks for clarifying, good to have learned something new

It would be great if you could add a memory meter..So we could see how much memory is left and used by the system
But other than that he app is superb keep up the good work

[Kernel] ardatdat kernel v1.6b3 [CWM] (2012-04-06)

Dear all,
As I have already distributed the v1.6b1 (beta 1) to some (many?) of members a week ago. I have been requested to open a new thread such that I could highlight what have been changed and let all testers to express their feelings and opinions to the new kernel in this centralized thread.
First, let me introduce the features of "The New Kernel" ... (not The New iPad)...
1. Stabilized the voltage & frequency setting such that the 'stock' voltage is used without affecting OC stability.
2. As different machine's CPUs are different, OC to 1.35Ghz is not the most stable setting. Instead, 1.3Ghz will be the max.
3. Remove some of the useless codes used in v1.5
4. Pick some of the code difference from the official XWLA4 kernel
5. Add in support to read NTFS & CIFS file system
6. Switch to use the SLUB allocator
7. Disable ipv6 (unless I am told to add it back)
8. Other minor bug fixes
Next, let me conclude some of the comments from members on the beta:
1. Works fine with Titanium ROM 2.1
2. Undervolted it to 750mv @ 608mhz, more stable than v1.5
3. More smooth than v1.5
4. Not as warm as v1.5, so far so 'cool' in temperature
5. No lag, no freeze
So, welcome for more opinions, discussions and findings and let's discuss here. If everything goes right, I will release v1.6 within a few days
** Updated: v1.6b2 has been sent out to around 10 testers for testing

-- reserved --

just got back from long leave...
got your kernel but havent installed it yet..
on your last 1.5 i'm having problem with ONDEMAND mode. it does not smooth after long standby/idle. INTERACTIVE is the best setting for me. hope 1.6 is much2 better!..
gonna test it tonight woohooo!!..

My sister's Galaxy R is using the really old ODIN version .
Can I directly upgrade like this ?

Yes, it should be fine.
Flashing the kernel every time is flashing a 'new' one. There are not any dependency with the previous kernel.

4 days of intensive testing and I've found no probs. Can someone put his undervolting stable results?

help..............
first i used 1200 frequency on interactive profile on 1.5, i have no lags but just test 1.6 the same frequency i find some lags in adw transition and also battery is drain out very fast............................

Still I would love to see support for 2WCR

Thanks for your report.
As I think you are the only one experiencing that. Could you please elaborate more on the situation. Example: the SetCPU setting / profile setting / screenshot. Lag, how lag, and have you wipe the cache before flashing the new kernel? Have you tried to flash back v1.5 and see the situation. Also, battery drain is fast is strange as I use 'lower' voltage setting that v1.5.
Please help to test more and provide more information such that we could help in fixing the problem. Thanks.

when firstly i installed this i didn't format cache then restore to 1.5 but see ur instruction i format cache and again flash 1.6 since 2 hours flashing it runs quite smoothly now ....... in set cpu i have used 1200 mhz frequency and interactive profile but i doesn't change any voltage.......... please insist me if i have to change voltage either or frequency........

I tested frequency 1100 mhz and I must admit it's unbelievable how much boost i performance gives you clocking with just 100 mhz. I would say it's relatively the most efficient frequency. (if you compare differences between 1 and 1,1 ghz, and then 1,1 and 1,2 ghz).

Where can I find 1,6 version

u can't, it's still being tested, but if you want to participate send pm directly to ardatdat.

NTFS Support
Got my OTG cable today,
Plugged in my NTFS formatted Pen drive and its loaded with all gears.
Thanks ardatdat for bringing up NTFS support on my request.

I'm still on stock kernel, but will most likely update to ardatdat's 1.6 when released.
Is the performance boost perceived boost under general usage or is it synthetic benchmarks such as Antutu?

It was so funny. If v1.6 is not released, maybe you could all blame him for it.

currently testing it with asus zenfone 2.. it did stopped 2 cores when i select 2 cpu on screen on mode..perhaps this may help that asus bugsh*t of android os in their 5.0r2 rom..will give feedback later..and also many thanks!
edit : it seems that the apps doesnt save any setting that you choose after a reboot and return back to default setting..

seems like it doesnt help much, battery drain is not predictable because of android OS drain.. or maybe its because of zenfone 2 processor does not support core management, sometimes i feel like the phone is overheat when using 2 cores only. but the apps really working, it can shuts off the cores..

Sounds weird, on my Zenfone 5 it works ok (wakes up with power button nicelly).... are you sure it didn't wake up? If you're using 1 core it may have a little delay, like 1 second, before wake up).
The saving option is comming soon (next version almost done).
Thanks for your feedback!

If you look on a CPU app, the zf2 does underclock and disable cores automatically to save power, so core management must be supported somehow.

i never seen disabled core on our device..maybe its because of interactive/ondemand governor..but im hoping that asus unlock the bootloader so that custom kernel with hotplug governor can be developed..and i read somewhere ASUS stated that there is no core management for intel processor on zentalk..

I downloaded and get this issue with my h811 5.1.1 lg g4 6core cpu @rafaelrgi

Never tested it, but should work with more than 4 cores, the number of cores is read from the system.

How To Guide Optimise Stock Kernel Scheduler & Governor Setting

So, after months of using Pixel 7 family, surely we all know that Tensor 2 is not exactly the best flagship SOC in term of raw power or energy usage, probably due to it's "Exynos Genetics Trait"
that being said, doesnt mean it's down bad. And with some optimisation, we can always try to make it run better. One of the example is by seeing how much better it run on custom kernel. But what about other stock kernel user ?
Well, fortunately, as long as we have root access, the stock kernel still allow us to play with some parameter. And here are some tunables parameters that i use to balance the energy usage and responsiveness of the device. (my aim is 10% battery for 1 Hour of SoT and ±0-1% decrease during 6-10hrs idle)
If you want to know more about each parameters, you can google a lot of linux kernel documentation (like here for example : https://access.redhat.com/solutions/177953)
but for now i'll just write down the change and my configurations. (I used EX Kernel Manager to change the parameters) :
CPU Section :
Switch governors for all CPU clusters from 'sched_pixel' to 'shedutil'
Open "Governor Options" and change the 'rate_limit_us' for all clusters from '10000' to '0'
Open "CPU scheduler options" and use bellow value for respected parameters :
sched_wakeup_granularity_ns : 10000000
sched_tunable_scaling : 1
sched_min_granulatity_ns : 2000000
sched_latency_ns : 12000000
Memory Section :
Disable "ZRAM"
That's it for now. Try and feedback if you find any improvement in your energy usage.
I've been using it for weeks, and pretty happy especially with idle drain. As for SoT, normally i end up with 5-6 Hrs screen time when i down to bed with ±30% battery remaining.

Someone said that it reverts back once you reboot?

In the Franco Kernel Manager, there's an option to "keep" the new settings on a reboot. (Not sure about the EX Kernel Manager.)

Right, it reverts back for CPU Governor (Cluster 3) after a reboot. (with EXKM)

Then I tried with FKM and problem is the same.
I will see after the night how is my battery drain.
But i can't complain because i loose only 2 or 3% during night (8h)
(Bluetooth and 5G on) No wifi because 5G signal is good.
No custom rom, rooted, january update.

It's expected that it reverts back to default because it's controlled by multiple things. People shouldn't change the governor. There is a write-up on this in Freak's kernel thread.

Actually you can change the CPU governor from the default one to one of the additional existing alternatives.
The issue is just that the frequency scaling driver for the affected CPU cluster(s) will break if the PowerHAL detects that the Sched_Pixel governor isn't "there" anymore for doing the job that it is supposed to do.

I never wrote you can't change it, I wrote people SHOULDN'T change it to avoid the issues you mentioned.

You say to try to deactivate zram. Is there any real benefit? Zram is useful?

You save CPU cycles at the expense of additional vRAM.

If you use smartpack kernel manager there's an option to apply all changes with a script on boot. That's the way I've always worked with kernels that won't allow changes to stick on boot
