Kernel Guidance for ram

Hi,
I have installed red ribbon linux but it only gives me just 108mb of ram available. So, I searched and found some kernel which gives 220mb of ram.

This is the place where I found it:http://ps3.khore.org/bootos-v201

with the following quote:
"Maz11 said...
I managed to compile and boot chololo's kernel as well. I get:

ps3@debian:/media$ free
total used free shared buffers cached
Mem: 217632 186536 31096 0 3080 56708
-/+ buffers/cache: 126748 90884
Swap: 463864 380 463484

Two patches from Marcan's git repo were needed to get the lv1 memory. I uploaded the two debian packages. Just extract and install with

dpkg -i *.deb

then cd to /boot and

mv vmlinux-2.6.38-rc6 vmlinux
mv initrd.img-2.6.38-rc6 initrd.img

reboot and check it out.

Hope this helps"

What I really wanted to know is that, Can I use this kernel over red ribbon rc5 linux to get 220mb ram?
Are there any other kernel which gives more ram than red ribbon linux? or any tweaks to make it usable?

Thanks

First time in about 6 weeks (personal reasons) I started my ps3 to check this. Started lshw from the menu (settings, hardware lister) and lshw says 220 MiB...

Check the petitboot settings if hugepages=1 is added. If not, add it :)
You can change the petitboot settings in kboot.conf.

By adding that line, can I get 220MB ram?

I installed kernel from maz11 and I got 220mb ram but ntfs driver module is not working in this whereas with red ribbon linux default kernel I have only 108mb ram. Can somebody tell me how to get 220mb in red ribbon default kernel?

I get it, the available ram is 218Mb using asbestos, 108MB with otheros kernel.

Now I'm using asbestos kernel and its usable.

if you wanted additional ram you could have tried to swapon the RSX memory..

Code:

sudo su -

swapon -s

Check current SWAP

mkswap /dev/ps3vram

swapon /dev/ps3vram

vim /etc/udev/rules.d/10-ps3vram-swap.rules

# udev rules to automatically enable swap on /dev/ps3vram

# Copy this file to /etc/udev/rules.d/10-ps3vram-swap.rules

# Choose only one of the rules below

# Initialize and enable swap unconditionally

KERNEL=="ps3vram", ACTION=="add", RUN+="/sbin/mkswap /dev/ps3vram", RUN+="/sbin/swapon -p 10 /dev/ps3vram"

reboot

sudo swapon -s

Verify additional SWAP space

I think this is a rather dumb question but given that the PS3 has limited ram (we can't just upgrade the ram on the fly).

But on the line of Swap, anyone thought of using swap to get a similar feature like ReadyBoost on the PS3 (not sure the amount of ram available to us will be sufficient)?

It is called swapboot and (I think) it does the same as we do now with the rsx.
