KEVLAR SOURCE PAGE POOL 0 ROM REPOSITORY
Although I posted a rather extensive post about Dynamic Page Pool and how to change ROM's page pool, the majority of people is not comfortable with HEX Editing...
Given that fact, I will update this thread with the Dynamic Page Pool version of all ROM's that are published from now on.
If you want any particular version or ROM to be changed just PM me with a download link and I will promptly change it and upload it to my rapidshare collector account and publish it here.

a simpler hack is patch nk.exe once with a nice NOP then allow people to patch it with the old pagepool changer to any value at will =) see raphael elite rc1 nk.exe for reference.
btw does this "dynamic" thing refer to disabled pagepool (when it is set to 0)?

Thank you for the info
Yes, Dynamic Page Pool or Page Pool 0
P.S. I personally prefer to HEX edit... It's as simple as opening the file with a HEX Editor and change a digit in two instances... But yes, for «regular» users it is much simpler to do it as you suggest.
I am an SD Card flash method user
If you wish to live longer DO NOT use Microsoft
If you despise life use Windows XP
If you have deep and severe death wishes use Windows Vista
If you are lunatic and suicidal use Windows Server 2003
Cheers.
Great news, really appreciate this thread !!!
Thank you very much, really appreciate this. I am one of those who would like to have the pp of the rom set to zero, but I feel really unsure about doing this myself as I have never used a HEX editor before. So thanx again for your time doing this for people like me.
Btw, I think I read your post somewhere in the ROMEOS thread giving the author credit for setting the pp to zero, but just to know for sure, is the ROMEOS rom set to pp=0 by default (newest 1.40 release)? Thank you

Say nothing of it It's always a pleasure to contribute and to help.
The credit of Raphael ROM's page pool change does not go to ROMeOS2 publisher... It goes to two other users and community contributors. (I won't say who they are. That's a secret )
Yes, your assumption is correct. ROMeOS2 1.40 both initial version and corrected one are Dynamic a.k.a PP0.
Thanx for the quick response
Thanks For The Great and Wonderful thread but i have two Questions:
does Setting the PP0 decrease and make the battery life shorter? and does it cause a memory leakage ?
thanks
Thank you for this thread and your help
Can you make this one dynamic to please?

Dear tinuz97,
The ROM you are asking me to change is already dynamic. I.e. It already has page pool set to 0.
Happy flashing.
Cheers.

Dear respider,
You asked the exact same thing in another thread some time ago and i believe that both me and JCEspi2005 answered you back then.
But I will «refresh» your memory
No there are no cons at all in using dynamic page pooled ROM's i.e. page pool set to 0.

um, you realize that the notion of dynamic pagepool is invalid,
i'm not sure who the heck invented this myth; but there is no such thing as a "dynamic" pagepool.
first, CE pagepool != windows pagefile. pagepool is an area that CE uses to page code and memory mapped files from NAND into RAM; it is not a pagefile that is used AS ram, when CE runs out of memory, it runs out of memory, no way around it...
as you know, the main disadvantage of NAND over NOR memory technologies is that NAND must be read/written in blocks, quite large blocks kb in size, the microprocessor unfortunately, needs memory to be byte-addressable. the whole point of the pagepool is to hopefully predict which pages of code the processor might need/use so it doesn't need to fetch from slow NAND, while at the same time reducing the RAM footprint so the entire code need not stay resident in memory the entire time... CE must reserve a preallocated amount at boot for that.
when you set that location to zero, it just tells ce to either disable the pagepool, or to use the OEM default pagepool instead of a preset pagepool.
i hope this dissolves the myth, although i'm 100% sure people will still go nuts over it...
Page Pool, Pool Resources and Pool Resource Depletion

The page pool is a reserved area in memory for the windows mobile kernel.
A ROM in a pocket pc is mainly divided into 2 parts [some other: IPL, SPL, ExtROM but forget it for now]:
- The Kernel
- The OS files [IMGFS] [Some pocket PCs do not have NOR/NAND ROM but a DOC (Disk On Chip) that works like an SD card].
Applications use RAM in two ways.
There is code that runs, and there is data that is created while it is running.
On a NOR device, the code can run directly from the ROM and not be loaded into RAM first. This process is called XIP [eXecute In Place].
NAND devices can't XIP, so their code is loaded into RAM and executed from there.
If you don't have a Page Pool, this code is loaded into normal RAM.
The Page Pool is a mechanism to limit how much code is loaded into normal RAM.
With a Page Pool, we can unload code that hasn't been used in a while and reload it later if we need to.
We can't do that without a Page Pool.
There are portions of the deepest parts of the OS that have to XIP.
If you're on NOR, that code just XIPs like everything else.
Not so on NAND... For a NAND system to boot, it needs to load this code into RAM first and then run it from there.
When the system is running, it can't really tell if it's running from RAM or ROM, so it assumes it's running from ROM and doesn't count this space.
Discussing pool resources and pool resource depletion in general terms and not specifically regarding PPC's...
When a machine boots up, the Memory Manager creates two dynamically sized memory pools that kernel-mode components use to allocate system memory.
These two pools are known as the Paged Pool and NonPaged Pool.
Each of these pools start at an initial size that is based upon the amount of physical memory present in the system.
Pool memory is a subset of available memory and is not necessarily contiguous.
If necessary, these pools can grow up to a maximum size that is determined by the system at boot time.
So, what distinguishes Paged Pool and NonPaged Pool memory is:
The first difference is that Paged Pool is exactly what its name implies - it can be paged out.
The NonPaged Pool cannot be paged out.
Drivers use the NonPaged Pool for many of their requirements because they can be accessed at any Interrupt Request Level [IRQL]. The IRQL defines the hardware priority at which a processor operates at any given time.
Page Pool set to 0 is usually refered to as Dynamic Page Pool because it allows the system to use all available memory as page pool, being it addressed and reserved on a necessity basis.
If you need more information I can provide you with some links regarding Page Pool and it's issues, many provided by Microsoft itself [msdn, that is]...
Remember that this thread is a ROM repository.
It is meant to be directed to general public. Therefore, discussions about this, especially technical ones should be taken to PM and not to open forum, at least in this thread.
You have your opinion and I respect it although I do not share it... Nevertheless users are free to use what they very well please. If you do not like it or if you believe it has no purpose simply direct your attention to other threads
If you take a look at the forum you will conclude that some chefs, respected ones, decided to publish their ROMs with Page Pool set to 0... Don't you wonder why that is?
Cheers

Thank you, I really didnt see the answer in the other topic, I'm sorry
But I remember I asked why custom roms and official roms doesnt come with dinamic page pool by default? ROMeOS seems like to have it only in 1.40, right?
Because its a "new discover" or because some people really dont like it?
Thanks in advance for answering and for the great topic.
Abraços.
Hi All,
This SD build is hiding away in the NAND section! There's a link to it in the 1st post. Try it, it's a solid vanilla Android Gingerbread port for our Leo. It may be a month old but I think it's still a brilliant build.

Hello,
Yes it's a great version stable and smooth.
Also no battery drain
But no possibility ask question. For example the persons who call have an echo.
Thanks for share

I'm not experiencing the echo you mention. Have you tried posting in the original NAND thread (or is that too obvious and shouldn't be said ) ?

Camcorder video recording brevity
I've been using sd rom builds since Aug 2010. The NexusHD sd build of Nov6 2011 has been the best I'd used hitherto, for example it had practically ZERO battery drain when going to bed at night and, setting at flight mode, only 2-3percent drop if on 2g only.
It was also the first build I used that recorded video at 720p. The videos were beautiful. However, it is unable to record (viewable) videos for longer than 10 - 16 min (it varies). Matching the size of the video (roughly at the time the recording begins to go wrong) approximates the size of the free RAM (usually btw 200 - 280mb), at least according to my observations. I got similar results with all the MIUI builds released within the last 2 weeks (Jaguaralani, MccM, etc).
This makes me think that the kernel arranges things such that video data is continually stacked in the RAM and is only placed in the storage medium when recording is signalled as complete (instead of doing so during the very process of streaming in the video data so as to free up the RAM and enable only the size of the destination storage medium - sd card or internal memory - to be the limiting factor).
Since I always want to have windows mobile as a bootable option in case of emergency access to files (- I use my hd2 for all my important stuff and am not always with my laptop) NAND builds are out of the question for me. However, the dorimanx kernel was said to solve this problem (and others) when used to replace the tytung kernel in the NexusHD NAND build in post 8716 on this page==> http://forum.xda-developers.com/show...05060&page=872.
So I have two requests: 1) Could an equivalent kernel for sd builds be pointed out to me? 2) How does one replace one kernel with another in an sd build?
Thanks a lot!!!
Why do I get pretty high battery drain using this v3.2a?
How can I troubleshoot what process is actually using the power?
I loaded this SD version to my HD2 and like it very much - except that I'm getting the dreaded SOD (sleep of death). This is a plain vanilla HD2, using the stock SD card (SanDisk class 2?)
Anyone know a fix? If the problem is the slow SD card, would a NAND install solve it?
Hi folks,I hope I'm in the right forum for this (otherwise could a moderator move this topic ? thanks).
I was thinking of the well-known build.prop trick to force the home launcher into RAM :
ro.HOME_APP_ADJ=1
I was wondering if the same trick could be used to force other apps into RAM. I'm no expert, but assuming the command is ro.[NAMEOFTHEAPP_APP]_ADJ=1 , we could have for example :
# Messages app :
ro.CONVERSATIONS_APP_ADJ=1
# Phonebook app :
ro.PHONEBOOK_APP_ADJ=1
# Telephone app :
???
I have been told this trick wouldn't be necessary because these 3 apps are auto-reloaded into RAM. Well, all I know is that within my GB Arc S, these 3 apps are fast after a reboot, and become very sluggish some time after. I guess they wouldn't if they were really forced to remain into RAM !
Sure, in case of a lack of RAM, other apps would become slow. But I'd still prefer if the three apps that I use most were fast and the other ones were slow, than the other way around.
Could you please help me with these commands ? Thank you.
no possible in any way... + that "hack" is old and does not work anymore (ICS+)
That "hack" works under GB, which is great since I'm running GB right now and I don't intend to go ICS or JB for the moment. :angel:
This being said, I'd appreciate if you'd explain why under GB it isn't "possible in any way" for the above-mentioned apps, while it's possible for the Home launcher. Just trying to learn something here. Thanks.
(thanks to Sgt. Slaughter for moving the topic to the right section)
Hey folks, would it be possible to get a decent answer ? I think my above question is clear enough and deserves it for those like me who run GB...
Thanks again !
Hello and good evening to all, sorry for my English but I am a boy of Italy, I wanted to ask if there is a way to increase also virtually the ram of my s3 for when launching games like dead space, asphalt 7, need for speed etc..
I have a 32 gb sd card class 10 I do not know if it can be dangerous to create swap partitions for cpu.In waiting for your response I offer you my greetings.
galaxy s3 rom omega v.43.9
try lidroid rom v19
it's very nice, i very like it.

you want more free ram? close the background apps using task killers like greenify(root required). ram usage depends on how you use the phone.

use a kernel with zram support such as Boeffla kernel. It's like a virtual memory thingy. More info on the thread itself.

ok guys I would not change rom, if I installassi only greenfy improvements?
By creating the swap file or not you have any improvements? Some people recommended to create swap file because of too many reads and writes to the sd which would be submitted.
