Enabling SWAP fails on T-Mobile Pulse - Please advise

[Guest zooly]

I have a rooted Pulse, with Busybox installed.

Tryed to enable swap in most possible ways,

- creating swap partition on SD card

- creating swap file on ext2 and fat32 partition

# mkswap <swapfile>

Worked without errors in case of swap files.

But:

# swapon <device|swapfile>

Always failed with the following message:

e.g.: swapon: /sdcard/swapfile.swp: Function not implemented

I've Googled a lot, and found that possibly the Kernel does not supports Swap at all...

Is there any compiled (or can anyone compile?) kernel module to insmod and get swap working with the kernel?

Or is there any other ways to solve this problem - without changing the default ROM to a custom one.

Thank You!

Have a look in this thread: http://android.modaco.com/content/t-mobile...-mck-for-pulse/

But to sum up for some reason the Pulse does not work with a Swap Partition, even with a Swap enabled kernel.

If you're using a custom ROM, it should work with a swap file. You might need to disable compcache first though?

hmm not able to have both ? havent tried yet.

was wondering though since swapping puts quite the stress on your sd card. is it possible to create a swap file on the phone itself? i still have like 90mb free in there .. or is that memory just as undesirable for swapping as sd card is.

You can have compcache with backing swap I believe.

No, you can't create swap on YAFFS partitions (i.e. the phone itself).

was just wondering cos i saw a bunch of youtube movies claiming to have both compcache and swap enabled .. but i dont want to wreck my sd card in mere weeks/months so thats why i asked about phone memory.

Both compcache or disk cache should be fine for me, but either not working with the default kernel.

There is no way to add swapping function (via a loadable kernel module) to the kernel without replacing it with a custom one?

I want to made few-as-possible modifications on my phone to get swap working.

Solved it with the kernel mentioned above.

Firstly, apologies if this is a complete noob question and has been answered elsewhere, but I've searched a bit and, to be honest, I'm not ENTIRELY sure what to search for... But, is this compatible with the MCR 1.2 ROM? It's not gonna brick my phone? Just that in the tutorial, it mentions how to increase the phones speed WITHOUT installing a custom ROM, and from what I've read, I think MCR uses its own custom kernel? Not very tech-savvy with phones yet :)

Thanks in advance!
