Regain Full mem without reset.(challenge) - Mogul, XV6800 ROM Development

Hey guys i think this should be an important challenge to overcome maybe find out where all the ram is going and get it back without reseting our precious moguls. My experience its something that Task manager doesn't show up because when i end task on my DCD 3 1 2 ROM i dont get all of my memory back like right after reset. Also this causes inconvinient problem of starting GPS after few days of RAM going down to 8mb and not having enough to lunch TOMTOM.
Oxios doesn't not regain full mem only one third of it.
Can we some how make a better task manager or maybe purge RAM?
Writing a driver to consider our FLASH cards as constant RAM?
I would gladly sacrifice remove ability of my MicroSD for extra 4 gigs of ram and would let my memory leak on a period of roughly 4 years of constant usage.
Please lets get organized and stop hoping the next ROM upgrade will solve this issue.
This is one of the biggest downfalls of the mogul

I would suggest looking into how RAM works before making this thread.
First off, most of our ram appears to be lost due to memory leaks.
http://en.wikipedia.org/wiki/Memory_leak
And since, at least in my experience, most of the memory leak comes from Windows 6 (and so much worse in 6.1), you can't exactly end the windows task unless you...
restart the Mogul.
So no, an application, or task manager, wont do you any good. Not until they fix windows 6.1 up to not be lord of memory leaks. That is why new roms are often so desired, because only a rom release with some decent version of 6.1 with hopefully some patched memory leak holes could help our problem.
Second, you can't use a flash drive as ram, at least its not reasonable. You think the Mogul slows down now? Wow, just wait to you see it moving at the blistering pace of a microSD card.
Ram is so small, and so expensive, largely due to its speed. Thats why you can buy a 500GB HD for about the cost of 4GB of RAM on your computer.
Also, running from the MicroSD would be similar to the page file on your home computer. It runs from, in most cases, your C drive, its a fairly large file, getting even larger when you run multiple tasks on a low RAM system.
It is slow as a dog, and is one of the worst causes of system slowdowns. I also believe that MicroSD's have a limited number of read/writes. While not an issue so much for everyday use (taking pictures, running an app from time to time), if it were used as a swap file, it would probably wear out that SD card pretty quick.
So no, short of an amazing, simple amazing, piece of software engineering on Microsoft's part on a new Windows Mobile, someone developing some sweet, easy to install ram upgrade, or the new replacement for the Mogul coming out with more ram than we know what to do with.
You will be restarting your Mogul.

It should be possible to wright a Driver to USE RAM for swap file and some of main drivers but MicroSD card to be used to run all the extra features and programs. Also why our team of coders cant plug the memory leaks or find out the runing programs not seen by Task manager and have option to close them?
PS
Thanks for confirming my worst dream about the limits of our mogul. Also I notice that PPC on palm trios seems not to have these memory leaks.

This is maybe possible if we can build a tool that can reboot the shell without rebooting the actual OS. It can be combined with the command to free the memory when the OS is unloaded. This is my theory, i think that we can recover memory like this

while every single statement you say is true, your only wrong about how long ti takes to wear out a flash device. According to Toshiba, the inventor of Flash memory and one of the top suppliers of Flash memory chips, the 10,000 cycles of MLC [Multi-Level Cell] NAND is more than sufficient for a wide range of consumer applications, from storing documents to digital photos. For example, if a 256-MB MLC NAND Flash-based card can typically store 250 pictures from a 4-megapixel camera (a conservative estimate), its 10,000 write/erase cycles, combined with wear-leveling algorithms in the controller, will enable the user to store and/or view approximately 2.5 million pictures within the expected useful life of the card.
For USB flash drives, Toshiba calculated that a 10,000 write cycle endurance would enable customers to completely write and erase the entire contents once per day for 27 years, well beyond the life of the hardware.
take into note that is only 10,000 write cycles. 100,000 which is common for most flash drive now a days. so no, he wont even be around to see the day his flash drive even wears out. LOL.

Glad to see this post picking up some steam But lets Try and focus on making A solution rather than discussin known facts

the known facts have already pointed out the problem (memory leaks in the OS) and the only solution we have without the source code (restart the OS by rebooting the phone) so what else is there to discuss?
oh yeah, we can talk about ways to get the source code so we can fix it.

well i posted one idea:

Would you Trade EXT_Rom for Storage or Program Memory??

I'm way out on a limb right now checking out a few different things for v0.30. A lot has been learned with v0.20 and will be applied.
So my question is:
If I can find a way to eliminate Extended Rom and turn it into either Storage Memory or Program Memory (or both) which is preferred?
BTW, I've already been able to increase Storage Memory to over 60MB (See attached Image)...

I agree, I always run short on Storage and have enough program
Storage is the first to run low.. same as the above.
-mix
I don't agree with all of you Storage can be buyed but program memory is limited. Who knows the memory requirements in future WM6 programas.
My vote for program memory!
I'm with Viva. Low on storage? Move programs over to the card. Low on RAM? You're screwed. I say move it over to Program memory. That seems to be the most logical.

Many are having problems running programs from Storage Card too, some think this is the root of some sleep lockups too. How many people ever runout of Program Memory? Maybe we should do that poll. I have a hard time keeping more tan 7MB free in storage., but I have at least 15-19MB free in Program.
Hi kyphur,
i think an additional 10mb of storage memory wont be sinifcant as the 60mb you have achieved in wm6 is suffice. if we need additional storage memory we have the sd cards to take care of it.
10mb of PROGRAM MEMORY is significant as we only have under 30mb free on a fresh hard reset and after a day of use this drops to about 24mb or less. the extra 10mb will allow us to run, well in my case, many apps with ample program memory and not worry about bogging down the system.
Therefore my vote goes to program memory.
But I have one concern with using ROM storage as program memory. RAM and ROM differ signifcantly in terms of technology and the ROM has much slower access rates than RAM. Would this have a signicant impact on performance?
Nonetheless, id still prefer it to be program memory.
Alot of programs run better from internal storage than from a storage card.
As already mentioned I havent run out of progam memory yet. But there again I have never run out of storage space either.
So my vote is for two thirds storage one third programs as apposed to half and half just to be different.
By the way keep up the good work kyphur, it is much appreciated.

I suggest you max out that storage to see if it actually is valid or not.

That is true too, if there are any doubts as to reliabilty, stability then go with storage as well.
50 - 50 Split for everyone.
I have an Ultra 1 Gb SD Memory card Fitted (Faster than std SD) and I have Not loaded any programs on the Phone. (Everything is on the SD) but I am starting to see that my Program memory is getting Low. So I would benefit from more program memory.
I don't know if the Ultra Card makes a difference but I have very few if any Lock ups / Freezes.
I do agree with most on max the storage to see how stable it is...., but I would like both. An option to do either on the fly would be even better.
kyphur, lots of thanks for the great Roms you're cooking and developing! one question though, if Extended Rom gets eliminated in the next version, then will there be some way left to make programs like theft alert survive hard resets?
no no... I mean fill the storage up completely and then soft-reset the PDA to see if it's actually *real* space.
Program seems to make the most sense to me
Program is a good idea so is storage so that is why i vote 50/50. I am running out of both of them anyway.
I know I can use an SD card but it is not the same. SD installed apps causes the device to lock up at times.
Thank's a lot kyphur.
I'm democratic so 50 & 50 but, how wrote Olipro, before real test.
Well,split it even might be logical as few apps need to be installed in phone memory for better performance...........
My vote will be to :: release 2 ROMs ,one with more program memory and one with more storage memory and the users will decide which one to vote ...(will it be too much work releasing 2 ROMs??,if yes then Program memory wins!!)
Kyphur,
if you build two different ROMS, one with maxxed out program memory and one with maxxed out storage id like to run SPB benchmark and post the results for a better polling result....
edit... i would like more storage but dont want to lessen the performance...

Custom ROMS and Memory

Greetings,
Please forgive me if this is a stupid question or the wrong thread.
I am curious about memory allocation in Custom ROMS. I have an ATT Fuze and the Stock ROM stripped of junk had over 200MB of Program memory available. It seems like most of the Custom ROMs on this forum only start with 120MB or so.
It seems like most of the Custom ROMS all focus on the amount of Storage available rather than Program memory. With SD cards being priced so low that they are almost free, why is there more focus on Storage rather than Program memory? The phone cost close to $1,000 but I have an 8GB storage card that cost me $10.
I have migrated from an eTen X500 where I always struggled to find ways to free up program memory. Here it seems like there is no interest in program memory, only storage.
Not being critical, just curious about what I am missing.
Thanks for any advice.
Doug M.
You are in the wrong thread just so you know for future reference, but I'll answer your question. Many of the cooks do try to get you as much program memory as possible, and if you look on the threads for cooked roms, you'll find that they usually post the numbers for both. Several of the cooks also have a few different versions of their roms, so you can choose a lighter version that gives you more program memory. That being said, the TP already has tons of memory and gives you enough room to install tons of programs, especially if you're running a cooked rom.
There is only so much you can squeeze out of the Program Memory. I may be wrong but the Program Memory acts like memory cache for running programs. About the only way you can lower Program Memory is from removing files from the payload when you dump it and by moving around the different partitions to recover unused space. When I build my ROMs I have been using 16MB pagepool which eats away from the program memory but increases the quickness of windows a bit.
Storage on the other hand is so much easier to gain back...

Might the X2 have a memory leak?

I've had my suspicions about this since I first got the Droid X2. I think it may be possible for much of the lag many (most/all?) people experience at some time or another.
As a test, I can check free RAM in Advanced Task Killer when I first boot up the phone, and it will hover somewhere 150 megs with all user processes killed.
Then, when I check after 24 hours of constant use (with intermittent charging periods) I will struggle to get 100 megs with all user processes killed.
Finally, if I reboot the phone, I will be able to obtain a decent amount of freed-up RAM again.
Anyone experiencing anything similar?
Now, I must mention, I'm operating under the assumption that the X2 does not cache apps or files in the RAM. I suspect there is too little RAM at such a minimal speed to be able to clear RAM fast enough in the event that something non-cached is called on. I mean, even Microsoft was slow to use this cache method, as they first introduced it in Windows 7. A good example of this in Windows 7 is if you check the Task Manager, you will see that roughly only a quarter of your RAM is ever actually labeled as "free", even if you currently have no programs open or are using minimal amounts of RAM.
And it certainly doesn't feel as if the cache is working as intended if Motorola did infact implement it on our phones.
I have contimplated over this for quite some time and have also came to the same conclusion. But the real question is: What can we do about it?
Most likely nothing.
Not sure of this is actually the case but when V6 is ran for instance it does talk about cached apps and gives an "actual" free ram reading. I would guess that zepplinrox would not have worded it that way if it was not the case but I have no real evidence either way.

This did happen to me when I ran Advanced Task Killer on cm7. I'd start with a very good 190 free ram (insane I know) and after a few hours I'd struggle to brake 110

This is the nature of Android and Linux in general. When you start an app (or a process), it will remain in memory until it is cleared by the OS. The problem with task killers and Android 2.3.x and above is this: Android 2.3.x and above RESPAWN the killed task since the OS did not kill it. Plus, there is no way to FORCE to OS to kill an app that is in the background. What Android does is renice the process until it is a positive number, greater than 1, then it kills the process. Android 2.3.x was designed to "auto manage" those tasks. If you run htop from an ADB session and launch apps and use the back button to back out of them, you will notice that the amount of free memory diminishes. Then, after sitting for a time, the amount of free memory slowly begins to increase. When an app that requires a bunch of memory is launched, the Android will kill those background apps to free up more memory. In theory, it is a great way to manage the memory. In this respect, apps that have been launched in that past will start up faster. Personally, I like having control over things. You could possibly write a script that will renice a process to something like +20 and then Android will kill it automatically, but that would be a very risky prospect as it might kill RUNNING foreground apps as well.
Hope this little explanation helps!
Ciao!

Your question is a bit complex. See back when Droid X2 first was released it had 2.2.3 for most users, and didn't have very good application memory management. This was the start of many applications such as "Advanced Task Killer" that you mentioned. These apps were supposed to help in closing apps that were running all the time.
Things changed a bit with the Gingerbread (2.3.3) release. This initial release made the Droid X2 useable. In my opinion the DX2 prior to Gingerbread was nearly a brick! I had many reboot issues, FC, connection issues, GPS issues, etc. With 2.3.3 many issues were eliminated, while others were reduced enough that they didn't bother me TO bad.
2.3.4 came out to fix battery issues largely...
Now I realize you weren't asking for a history lesion, but it is useful to know these things to know where things were and where things are today. I am currently running 2.3.5/412 and have been for months. I can say from experience, Android DOES cache background processes. I thought it did back in 2.3.4, but i can't remember... I don't think it did back in 2.2.x or at least the OS didnt' inform the users via GUI.
Your question about performance though? Yeah the DX2 is crap! I love the physical layout, but it has MANY issues with performance... some have been reduced by doing build.prop edits, yet I have realized that many who post these edits have posted wrong.... for example, they are increasing the buffer sizes thinking this will help internet speeds. This is super complex, but Google "Buffer Bloat" and you'll see how larger buffers often mean greater throughput, but MUCH greater latency....
simply put... big buffer == faster download of individual files.... smaller buffer == slightly slower download but MUCH more responsive
I'm not sure if that answered your question or not... let me know how I did or if I just rambled perhaps =P

[Request] Kernel Dev's - Low memory issue

Hi!
Because of the low memory issue in the International edition, I request for all Kernel Dev's that implement the possibility of the use of Swap file.
There are programs that make and use this Swap file to get more free RAM, but this programs needs that the Kernel support it.
Like :
https://play.google.com/store/apps/...sMSwxLDEsIm9yZy5hemFzb2Z0LmZyZWUuc3dhcHBlciJd
https://play.google.com/store/apps/details?id=lv.n3o.swapper2&feature=nav_other
What do you think?
Cheers!
P.D:sorry for my bad english.
I think you are in the wrong section. There is a dedicated section for questions and not in the Development thread
What Low memory issue??? We have 1GB of RAM (almost) on the device! Everything works smooth on the phone!
maybe he wanna say that free memories are from 2xx~3xx mb only, which is actually less than S2 even S3 also has 1GB ram.
If the files can increase more free ram, it would be good for some heavy games and softwares to run more smoothly.
Wrong forum, but indeed I agree.
It's virtually impossible to run 2 heavy programs at once. One of them will always close when it's in the background, even if it implements a Service.
For example, Waze - It closes whenever I receive a phone call.
Just annoying. Problems I never had on S II

Swap will make the phone lag terribly since the ssd writing/reading speeds are far inferior to what you neel for normal operations.
It also makes sure the internal/external storage will not live very long.
While it's a good idea to combat memory issues, paging to disk is not suitable for normal situations.

Swap file to internal SD: max speed 26MB/s I think there is not a problem, but I prefer more memory. And I tell that implement the function and optional you can enable it, if you don't want you don't need to enable.
Cheers!
Can I ask you why you think you have low memory?
please select one of the following:
1) Phone going so slow it takes age to do anything I ask
2) Apps keep getting killed mid-use
3) I have looked at the numbers and they look low....
I can't choose any option. I want to explain:
-I open Internet Browser and open a Web with many videos, photos, etc, and browser closes itself.
-Open 1 game (NOVA3 for example), then put it on background to see a Web Page or check email... or open the Web browser, open 3 Webs then go to email to check, then go again to browser and all is closed, the phone needs to open all Webs again (in this case is your first option).
I think that you prefer a UNIX computer with 256MB of RAM than a UNIX computer with 16GB of RAM because you optimize the 256MB of RAM. I prefer waste memory (really don't waste it) because I want to RUN many programs at the same time.
Sorry for my very bad english, because I can't explain exactly what I want.
I'm SYSADMIN and I know what I say.
Cheers.
I understand where your coming from but I think you have failed to understand the purpose of multi-tasking on a phone (and the reason that not many phones have more than 1gb of ram yet).
Multi-tasking on a phone is designed to let you go from webpage to sms, or music to email etc, i.e. between smaller, less hungry apps.
Switching between a high ram usage game and other things is always going to be a problem, the phone was never designed to allow you to multi-task while gaming.
I know that this is a phone, not a Core I7 - 16GB RAM - SSD with Windows 7 Ultimate, but, Did you have a SGS2? with SGS2 you can make what you want and you don't have this problems off memory.
I said an example of a Web page with a lot of videos and photos that make Browser closed., not only with Games.
This is Why I want to try the Swap file. Off course if the phone goes slow down I'll prefer no Swap file, but I think that is a good idea.
Perhaps with a new firmware update Samsung solve this issue...

Have you ever had your Windows computer have to heavily page to disk (aka swap)? Even with my OCZ Vertex4 it's unbearable.
Just get rid of all the background apps (such as AllShare) that the S3 has running and you should be better off, it got rid of any hint of memory underrun I my had.
Get Houmiak TaskManager from market, find out which apps are running and freeze them in Titanium Backup. Problem solved

You are wrong.
This is my 4th Android phone.
Multitasking between several Applications which implement the Service Android Class should be possible without any of the services being killed.
I don't care about the Activity. I care about the service.
Example :
I run Torque & Waze at the same time and tend to skip between them.
If I receive an incoming call, they are both killed because of low memory.
How do I know? when I go back to either of them, the state is not kept, and waze even complains about not being stopped correctly.
Believe me I removed ANY resident useless services, uninstall about 30 system apps from wanam lite using titanium pro, and still, no good.
These things used to work on older phones like SGSII and Galaxy Note and even SGS I with stock samsung roms.
There is no reason SGS III should suffer regression in this department.
It is very easy to understand that while samsung have added plenty of "Cool" features to the phone, they have left us with an overwhelming amount of garbage. I want smart stay, I want usb OTG, I want the camera app, I want Touchwiz dialer and I want HDMI,
But not at the expense of basic use-cases.
Hell, on the Galaxy Note I was sometimes shocked at the amount of Activities left in the ram, I was impressed. Having 10 apps running in task manager. And no, I never closed them. I don't used task killers, and I don't care about "Free" ram.
I care about my Applications life cycle which sadly sucks on SGS III.
BTW, Galaxy Note had the same screen resolution give or take as the SGS III.
Something is terribly under optimized.
600MB used just by core crap.
PS. I am angry at samsung, not at you, apologies if I sound harsh.
It's also aggravating when posters here instantly assume other posters only care about Free ram. HERE - TAKE MY FREE RAM.
About the swap to sdcard, I'm not sure that is the solution.
But I am sure we need "A" solution.
Edit:
If anyone knows how I can understand exactly which process/app/apk/activiy/service is taking how much, I would happily compare it to Galaxy Note. I'm sure we will find basic applications taking too much.
If it's the GPU reserving too much memory, I am willing to settle for less GPU ram while not running games. Hell, the Galaxy Note was not that slower then SGS III
It even preserved me a lot of time which I now waste on Navigating multiple times with waze when it is closed because of a phone call.
Don't know if this has anything to with it as I haven't received my S3 yet. With the HTCOneX I had this problem as well. Then I found out, that in the
"settings".
in the "development section"
"Don't keep activities" which is unticked by default. One has to tick it ( I went on recent apps to make sure it would be saved) and then untick it again. Afterwards the HTC1X was quite cabable of multitasking. The default setting seems to have some hybrid impact and has to be set straight by hand.
Hopefully this helps your issue.

If anyone knows how I can understand exactly which process/app/apk/activiy/service is taking how much, I would happily compare it to Galaxy Note. I'm sure we will find basic applications taking too much.
If it's the GPU reserving too much memory, I am willing to settle for less GPU ram while not running games. Hell, the Galaxy Note was not that slower then SGS III
It even preserved me a lot of time which I now waste on Navigating multiple times with waze when it is closed because of a phone call.

I'm completely with you on this.. .. I have had both the original galaxy, the s 2 the note and other Android phones with this one being my first where larger apps are closing due to low memory resources. I had Nova, my browser, videos, music, angry birds and other processes in the background on my s2 with only388megs used out of 863.... this phone, I load the browser and everything in the background closes with 675megs used out of 754.... not cool. There must be some kinda solution.. why is it that my note and s 2 have 140 more free ram anyways?

New User Wants to Thank Group

I've been quietly lurking on this site for about 2 weeks since I got a nook tablet (16GB) with an N2A card (which was horrible). I came to this site looking for a way to mod my device and ended up learning a lot more than I intended. I have sampled quite a few ROMs on here and am astonished at the amount of work that has gone into these ports. I have a device that is so much more functional it's not even funny. Already I've reclaimed the space that BN had partitioned from users. I still have a lot to learn but I wanted to express my thanks to all the developers who work hard on these. I am very appreciative that a device which is technically 'obsolete' can be revitalized and turned into something very usable. I am still trying out various ROMs to try to see which is giving me the best stability and RAM use. So far the one I am using I unfortunately forgot the name of. Any way of finding out which ROM you might have flashed? What I like about it is most of the ROMs use so much RAM I am left with around 200MB of RAM without anything running. One particular ROM I'm using consistently gives me around 400-450 MB of free RAM even with some background apps running. A HUGE improvement. A couple ROMS literally left me with less than 100MB. Anyway if anyone has any advice or happens to know how to determine which ROM I might be using I'd be very happy. Mainly I wanted to introduce myself and thank the developers. GREAT STUFF!
Some info that most Android users are not aware of, as its a bit non-intuitive:
Having less memory (RAM) available is actually a good thing. Apps can be "running" in the background without actually using the processor or other resources. They are cached via the RAM in order to allow you to relaunch them quickly. Android's memory management is quite good, albeit different from say Windows.
This is why Task Killers are generally a bad idea. I used to use them as a means to kill apps when they froze or whatever, but now, with the roms I have on my devices, I have set long-press of the back button to kill the current app, should I need to do this.
Read this article for a bit more info.
tl;dr less memory available is not necessarily a bad thing on Android.
Sorry for delayed reply
Forgive my tardy response. Our internet was out for 2 days. I understand what you are saying but what I was noticing was a huge number of active programs that were not in use, nor are commonly in use enough to justify their being cached. One particular ROM was leaving me with less than 200 MB of RAM with the same processes referred to above being inactive as well. A 200MB difference with the same stuff running. The particular one I'm on now keeps a number of things running in the background and still leaves me with well over 300MB with 4-5 programs going at the same time. So while I agree with you that some might be doing more cache than others, my experience is telling me the build with the most RAM (ie whichever one I am using...I unfortunately forgot which I installed...a CM10 but not sure if it was the cherry pick or chris'.) is the one that is managing the memory the best. I can figure out no other explanation for the same number of programs using an extra 200 MB of memory over another rom and thinking that is a good thing. For example, the ones I am thinking of are running stuff in the background I don't even use. Power Amp is a huge offender for whatever reason. I see no reason to have it running 24/7 but it does!
