request to kernel devels

Guys, could u please include in our kernel deep-sleep and fast dormancy patches?
u know that its not so hard. sure, i can do it myself, but i dont want one else toolchains and kernel trees on my laptop lol. deep-sleep and dorm succesfully work on moto atrix now with 2.6* kernels
also please include stat timers in kernel configs in future?

Would you like fries with that?

Can the kernal make me sandwiches too? You know its not very hard to do just three slices of bread, toasted, Mayo, lettuce, tomato but only if its fresh, two slices of Turkey and two slices of cheese. And cut into triangles with little toothpicks holding them together.
And just to proove I'm not a jerk: please.

I can get 8 days battery life just leaving my G2x sitting there. That's proof enough that deep sleep don't do sheeeit.

Oh come on people, those requests are completely valid. Though, OP, next time don't "of course I could do it myself".

They're unnecessary and since no one had ever used those on a G2x kernel before, I'm assuming it would take time to figure it out. Time that would be wasted since the two things he is requesting don't help our phone at all. If he can do it himself, then he'll do it himself.

Well, those patches should increase the battery life which is pretty bad on our phone right now. My 1980mah battery did improve the situation a little, but it still doesnt come close to sony ericsson x10 or nexus s that i owned before.

I haven't really had any battery life issues. I charge my phone at night, and then use it all day.
If I go crazy with games and tethering I might have to plug it in for a few minutes during the day, but battery life doesn't seem any worse than other phones.

Just so the OP doesn't think I'm dogging on him, there are kernel patches I've wanted before also. I'd like a kernel that supports netfilter patches so I could use a nicer wifi tether app:
http://code.google.com/p/android-wifi-tether/wiki/FAQ
But, if it can't or won't happen, I'm fine without it. If I could do it myself, I wouldn't post about being too lazy to do it.

No, they won't. I can get over a week just leaving my phone there. Which should make it pretty clear that we don't need it.

ok, ill start by saying im only just now getting into how the Linux kernel works on ARM devices, so i might need a real dev to confirm some of this...
deep-sleep is just a name for a sleep state on some chipsets (i think Samsung mostly uses it) tegra2 has sleep states as well, infact we have a few (LP2 and LP3 just off the top of my head) and deep-sleep is not really needed on our devices (if its even possible to implement on this device)
tegra2 as a chip itself is perfectly capable of sleeping, and does so very well, NVidia even went so far as to make their own proprietary "governor" (if you can call it that) to control speed and voltages, as well as shut down a core when its not needed. so rest assured that when its not needed, our phone is already using as little power as it can.
with regards to fast-dormancy, seeing as the base-band/radio chip in our devices is already 'flaky' at best, do you really want you phone doing the equivalent of going into 'airplane mode' every time its done sending a message? plus, unless t-mobile can use an optimized version of it (which i don't think they do) its been shown to actually increase network usage, and decrease battery life due to constantly negotiating network connections and disconnections.
also, im going to assume by stat timers you mean 'time in state', in which case that is a HUGE undertaking including rebuilding major parts of the kernel if its even possible on tegra chipsets. plus, its really only useful to see if your phone is actually sleeping, which there are other ways to do this, although they are a bit tougher.
and finally, i don't know how you meant you question to come across, put please try to be more considerate with how you phrase things. these devs, for the most part, are doing this because they want to. nobody is paying them to work on our phones (aside from an occasional donation from time to time) and they do have jobs, lives, and families outside of these phones. and despite how easy you say it is, ive been studying the kernel in this phone for almost 2 months now, pouring over forums, datasheets, and many many many versions of kernels by morfic and faux123 and im only just beginning to understand the basic ways that things are done.
hope this clears some stuff up

Thank Klathmon, for the explanation.
I am still kinda confused though, OP said Deep Sleep has been implemented into an Atrix kernel which has the same tegra chip. Maybe you are right and they just refer to one of the low power states as deep sleep. Also I tried googling for deep sleep in atrix and nothing came up

Thanks for detailed response. I think i understand all the subtleties.
So mods, please delete thread

[POLL] general kernel feature discussion

Hopefully this will help new users know what to try first and perhaps kernel devs to get less requests in their threads. Feel free to make a list of your top 5 mods/features or whatever and comment on specific mods/features.
for example, have you noticed zRam to make a perceivable difference?
note that I am leaving overclock out of the poll since it is kind of a given in any custom kernel.
My apologies if I forgot your favourite feature!

Still not sure what the point of this thread is.
Anyway, I don't overclock with custom kernels because it makes scrolling not smooth. I would rather my phone be smooth than have some pointless number in my CPU app. Zomg 2.000000gHz!!1!11111111!!!!!!!!!
With zRAM enabled I can leave 10 tabs open, and come back to them in a month and they're all still loaded.

Ironic that the point of the thread is in the op, and then you contributed to it by the second half of the reply. So is this a pointless thread, or did you have something to contribute? Make up your mind. Let's try to keep this thread tidy.

I dunno, I guess I envision noobies reading the first post of whatever kernel they which to flash, which lists the various features of the kernel and what each option does. Having said that, that makes this thread redundant in my eyes. But hey, if that's what you want then I'm all for it! (hence the contribution)

Fair enough. But not all features work as intended. Reading a feature list doesn't expose which things actually make the biggest difference.
For example, in my experience zRam helps multitasking, but often my phone grinds down to a slow pace with it. We might have noobs posting in Rom threads about how much lag the Rom has without realizing it's maybe the zRam they enabled just because it seems like a cool feature. Now there is more junk in the wrong threads.
Sure, they can read up on it elsewhere, but I thought it would be helpful to try and get one x specific info amalgamated into one place.
Also, with a new batch of kernels probably coming up soon with JB leaks maybe this will help kernel devs prioritize their development without a hundred people asking for stuff all the time.

Zram shouldn't grind to a halt on this phone, maybe on older phones. Lowmemorykiller is still in effect and it's not writing to disk so it doesn't "thrash" like conventional swap. It's all written to fast ram and the performance penalty for compressing and decompressing is negligible with a fast dual core. I use it all the time.

Well, If I can take anybody's word for it, its yours lol. It must have been something else then.
The only other thing I changed was starting to use chrome, and when I was multitasking between chrome and anything else it was super slow...even to reopen the keyboard.
This is the kind of discussion i'd like to foster in this thread. (even if it means being wrong)
Sent from my HTC One XL using xda app-developers app

You're not necessarily wrong, I'm sure it could happen in certain situations. I find chrome to be very heavy on phones (complete opposite of chrome on the desktop). It may have kicked everything out of memory. That usually doesn't happen because most phone apps are fairly light.

Ya I agree, I usually underclock for battery purposes

Alright so I dont have a list but I am going to say that when I enable sweep2wake, I notice some lag all the way around the phone. Overclocking to 1728 has always been perfect for me. Can someone also look into otg on jellybean? I've been having alot of trouble getting that to work.

I think otg is supported in the jb sense stock kernel. (NB If you go to storage, at the very bottom there is a bar for usb storage.)
However, I haven't tried it for myself yet. Reading around I saw that the first time you may need to leave it plugged in for a while for it to register. some users reported leaving the phone with otg plugged and coming back later and it had shown up.
I wish I could remember which rom thread that was...but that's basically all that was mentioned.
Edit: Also, I don't know if the stock jb kernel will self power the otg device. You may need the special cable, if you weren't already.

Laggy Android Phone ? Here are some tips and tricks

After using your Android device for some time it may begin to slow down and lag, and this is quite frustrating for every user in such situation. The more apps you install on your Android device, the less memory you make available on your device. Then your device will become slower in processing your apps and this will definitely affect your battery life and device performance. Just like no one likes to use a slow computer, no one also loves using a slow Android device. So let’s look at how we can make our device faster again.
How to make your Android device faster again:
1. Reboot your Android device:
If your Android device suddenly becomes slow and takes unnecessary time to respond, reboot your device as this will kill all processes consuming your memory. Then you can launch your desired apps. If your Android is still slow after rebooting follow the steps below.
2. Uninstall unnecessary and unused apps:
It is a common practice for Android users to install a lot of apps, some of these apps are rarely used or unnecessary, uninstall such apps to make more memory available for other important apps to use in your device. Ensure to always keep minimum apps on your Android device and keep only the important ones. The less apps you run, the more responsive your Android device will be since there will now be free available memory to use.
3. Reduce the number of Widgets/Home screens you use in your device:
Reduce the number of widget your device and also reduce to its minimum the number of Home screens on your device. Widgets consume your memory as their services run on your device even when you are not using them. Reducing them will make more memory available.
4. Install a Custom ROM:
Since newer versions of Android OS performs better than their older counterparts, it will be wise to install custom ROMs to get a newer version of Android OS. This will make your device more responsive.
5. Transfer apps to Memory Card:
As much as this may involve rooting your Android device, moving apps to your memory card will make more memory space available in your internal memory which serves as RAM to your device. A2SD is an app that can allow you to install apps on your SD card rather than your internal memory and this will help you ensure more internal space on your device.
6. Turn of unnecessary services when not in use:
It is advisable to turn off services you are not using anytime you are not using it. Services like Wi-Fi, Bluetooth, GPS etc. Most times even when you are not using an app, its services may still be running on the background, so killing the services manually will make more space available to other apps.
Final Thoughts:
So much have been written about this topic in so many blogs, no matter what have been written one thing remains certain, when you install so many apps, your memory is used up and your Android device requires memory to process quickly, so when the memory have been used by other apps, it is always difficult for your device to perform as expected. So I will advise you to always ensure good memory management practices that will always free up internal memory for your Android device to perform optimally.

You know the old saying "Doc it hurts when I do this" .
Well don't do that then....
If your RAM is half full consistently, then your ROM is broken. The Android (Linux) OS memory manager strives to keep the RAM 80% used /full all the time so that apps load faster. If its less than that you either don't have any apps installed or, you dorkeked something. Lots of times people try to use auto task killers, which work against the OS and cause much memory thrashing and gnashing of teeth and resultant poor performance. Having 60% of the RAM free might make you feel better, but it won;t make your phone faster, just the opposite.

He says it should be compatible as is or with little modifications. Thing is, i dont know where to start. Anybody interested?

you can't "port" a kernel. but you can build a kernel from n5 source based on that kernel source.
if you don't know how to build a kernel, and not just building a ready made kernel, then you have quite a bit of reading and getting educated(educating yourself even) first.

Well i guess i was hopin someone a little more educated than myself could help me through it.

I do wish you much luck though, as I'm the wrong person for help

it'll involve quite a bit more than cherry picks, as the kernel, and all the numbers involved in the kernel, are for a nexus 7. the far majority of things would need to be changed/adjusted for a nexus 5.

that's what I was getting to in my first post, but was trying to be easy on the op as possible
we have more ROM builders than kernel builders for a reason, because its much more involved. while it is very possible to build this kernel for the n5, it would be extremely difficult and time consuming(changing numbers and testing) for someone who has never built a basic kernel.
maybe he can talk the original dev into building a n5 variant. or talk a n5 kernel dev into it

I understand. The the original dev has been having some health issues and just got back to deving again, i really didnt want to bug him when hes already working on his own stuff,. But i assumed it wouldnt be too hard because he said it shouldnt take much modification. It would be nice if someone could do this, it is a very nice kernel. I get 7 hrs screen time with it and performance is amazing. I just thought it would be half way there considering the devices are similar

its a different device, period. you can not compare the two. on the n7, its very easy to get 7+ hours sot. on the nexus 5, you have to turn everything all the way down and not really use your device, except keeping the screen on for long periods. just because a kernel does well on one device, still doesn't give it a good chance on another. the best kernel for any device will be made specifically for that device. every device is completely different, has different hardware, has differently tweaked CPU(if the same CPU), has different powering and voltage needs, etc.. what can be used are the tweaks/mods he's using. but the chances are if its usable on a n5, its probably being used already.

Nexus 5 has a 2300mAh battery and a Snapdragon 800 at 2265MHz.
Nexus 7 (2013) flo has a 3950mAh battery and a Snapdragon S4Pro quad-core 1.5GHz processor plus doesn't have a phone radio as it's Wi-Fi only.
If you're comparing battery life between the Nexus 5 and Nexus 7 you really need to do some more research.

na, its just junk you keep hearing repeated over and over. battery life mostly depends on how you use your device, how you personally set it up, what apps you use, and the quality data(or phone) signal you get. kernel might make a slight difference, but its not really much. changing how bright you keep your screen could make a bigger difference.

For one, i didnt say i thought id get those 7hrs on my n5 im not that stupid, you are just assuming that. all i was saying is thats pretty good even for that device. I understand their different but its not like im asking to build it for the galaxy s5, THAT would be way different, get my drift?

Screen and radio are the biggest 2 drains... Keeping the CPU ramped up can do a lot too and although that is controlled by the kernel, the settings in the governor can change how the kernel controls the CPU.
Many people assume that kernel x is better on battery and kernel y is better in performance but really the difference is that dev x and dev y set their default settings for the governor in bias to battery and performance respectively.. May user can make kernel x bias toward performance and kernel y bias towards battery, the opposite to original config.
Sure some optimisations outside of this will halve small impacts over stock but devs share a lot so they're usually available across the board.

I did assume that's what you meant, sounded like it though. sorry

But i understand what your getting at, different voltages clock speeds, all i was looking for was some advice. The attitude you guys are taking about it and the attitude the dev of the kernel took about it is like the difference between two politicians at voting time, two completely different views. Now i understand he doesnt use this device but he understands what it takes to do it, now i dunno where you guys stand when it comes to the knowledge it takes to do something like this but all i was looking for was some advice, not a OMG you know nothing battle
