#!/bin/bash

test -b /dev/zram0 && exit 0

ENV_CONF=‘/etc/pop-zram’

if test -f ${ENV_CONF}; then
export $(grep -v ‘^#’ ${ENV_CONF} | xargs)
fi

test -n “${ALGO}” || ALGO=zstd

test -n “${MAX_SIZE}” || MAX_SIZE=16384

test -n “${SWAPPINESS}” || SWAPPINESS=90

test -n “${PORTION}” || PORTION=50

if ((PORTION > 200)); then
PORTION=200
elif ((PORTION < 1)); then
PORTION=1
fi

test -n “${PAGE_CLUSTERS}” || PAGE_CLUSTERS=$(test zstd = ${ALGO} && echo 0 || echo 1)

TOTAL=$(awk -v p=${PORTION} ‘/MemTotal/ {printf “%.0f”, p * $2 / 102400}’ /proc/meminfo)

SIZE=$(((TOTAL > MAX_SIZE)) && echo ${MAX_SIZE} || echo ${TOTAL})

modprobe zram num_devices=1
udevadm settle -t 1

zramctl –size “${SIZE}M” –algorithm “${ALGO}” /dev/zram0

mkswap /dev/zram0
udevadm settle -t 1

swapon -p 1000 /dev/zram0

sysctl -w “vm.page-cluster=${PAGE_CLUSTERS}” “vm.swappiness=${SWAPPINESS}”

MINIMUM=$(awk ‘/MemTotal/ {printf “%.0f”, $2 * 0.01}’ /proc/meminfo)
CURRENT=$(sysctl vm.min_free_kbytes | awk ‘{print $3}’)
if ((MINIMUM > CURRENT)); then
sysctl -w “vm.min_free_kbytes=${MINIMUM}”
fi

an were if i can do i adjust the vm.page-cluster= setting an what options
are ther an ther effects
