Potential Memory Leak Introduced in Snapshot (August - Sept 2023?)

For Developers

I have no idea how/why it stopped doing this for me.

Have you tried setting the irq's and rebooting as per here?

If that works, you can put this script in your rc.local (local startup), before the exit 0:

##########
# IPQ807 does not properly define interrupts, so irqbalance does not work.  Set static values.
# https://github.com/Irqbalance/irqbalance/issues/258
cat > /tmp/set-ipq807-affinity.sh << 'EOF'

#!/bin/sh

set_affinity() {
    irq=$(awk "/$1/{ print substr(\$1, 1, length(\$1)-1); exit }" /proc/interrupts)
    [ -n "$irq" ] && echo $2 > /proc/irq/$irq/smp_affinity
    logger -t /tmp/set-ipq807-affinity.sh "Setting Affinity: $1 ($irq) to $2"
}

# assign 4 rx interrupts to each core
set_affinity 'reo2host-destination-ring1' 1
set_affinity 'reo2host-destination-ring2' 2
set_affinity 'reo2host-destination-ring3' 4
set_affinity 'reo2host-destination-ring4' 8

# assign 3 tcl completions to last 3 cores
set_affinity 'wbm2host-tx-completions-ring1' 2
set_affinity 'wbm2host-tx-completions-ring2' 4
set_affinity 'wbm2host-tx-completions-ring3' 8

# assign 3 ppdu mac interrupts to last 3 cores
set_affinity 'ppdu-end-interrupts-mac1' 2
set_affinity 'ppdu-end-interrupts-mac2' 4
set_affinity 'ppdu-end-interrupts-mac3' 8

# assign lan/wan to core 4
set_affinity 'edma_txcmpl' 8
set_affinity 'edma_rxfill' 8
set_affinity 'edma_rxdesc' 8
set_affinity 'edma_misc' 8

exit 0
EOF
chmod 777 /tmp/set-ipq807-affinity.sh
