How can I share the RAM area in a percentage rate!

[xor]

How can I share the RAM area in a percentage rate!
50% RDD (Ram disk driver) space
50% hardware physical RAM usage Space
or
10% RDD (Ram disk driver) space
90% hardware physical RAM usage Space
in the form!

(%) percentage rate,
I want to change it manually.

[xor]

can you explain these issues simply !?
question 1 :
How can we change the free space configuration on the system RDD!
question 2:
How can I configure the swap space!?

... How can we change the free space configuration on the system RDD! ...

Are you talking about  zswap ? You can disable that with the  nozswap  boot code. Or to resize it, maybe this will help you:

[RAM 4GB] = TCL-RDD (*) 2GB + RAM 1.5GB + SWAP 0.5GB
(RDD: RAM DiSK DRiVER)

if a configuration like this is desired
what are the commands that must be done to reach these values. !?

Ignore the link I posted, it's too old.

By default, Tinycore uses 25% of your RAM for  zswap (swap space in RAM). If you want to change the amount used, try this:

First, boot using the  nozswap  boot code.
Then

Code: [Select]

sudo su
# remove all existing swap
swapoff -a

# Set the size to 50000 K bytes
echo "50000K" > /sys/block/zram0/disksize

# Create the swap file
mkswap /dev/zram0 >/dev/null 2>&1

# Update fstab.
echo "/dev/zram0  swap         swap    defaults,noauto   0       0" >> /etc/fstab # Lets swapoff -a work

# Enable this swap device first so it has priority.
swapon /dev/zram0

# Enable any remaining swap devices.
swapon -a
exit
To see the status of your swap devices:

Code: [Select]

cat /proc/swaps
If this does what you want, then add it to your  /opt/bootsync.sh  file before the line that calls  /opt/bootlocal.sh.  Do not include
the lines that say  sudo su  or  exit.

I understood shaping the SWAP space
Question: How can I shape the RDD area?

I don't know what or where the  RDD  is.

Is it true that I understand!?

Virtual disk space created on RAM,
RAM limits are constantly updated by the system

Is this review a correct one?

Hi xor
Yes, the  rootfs  is in RAM.
If you want to know out how its managed, you will have to ask Google, because I don't know.
If you want whether you can control its size, you will have to ask Google, because I don't know.
