My startup commands:
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] || continue; echo -n ondemand > $CPUFREQ; done
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

Should I change the first command to be the same as blkt?
How is it CPUGOV different to CPUFREQ for the EA8500?

Cheers


It is the same it is just the name of a variable you can also call it CAT or DOG Smile

@blkt , the fastest forum guru on earth Very Happy

Here is mine and it suits me.
my 'sampling_down_factor' = 1 which is default if you set to 'ondemand'

So, common threshold and sampling_down_factor settings for all CPU's.
Thank you very much, blkt.

Thanks guys!
I've resisted the urge to make the variable CATS!
Stay safe - I'm stuck at home apart from weekly shopping.

Router Model: Netgear R7800

Firmware Version: DD-WRT v3.0-r42819 std (03/30/20)
Kernel Version: Linux 4.9.217 #536 SMP Mon Mar 30 02:08:38 +03 2020 armv7l

Upgraded from: DD-WRT v3.0-r42729 std (03/18/20)

Reset: No, not this time

Status: Up and running for 8 hours, basic setup as Gateway, static leases, OpenVPN client (on PIA) with Policy Based Routing up and running, 2,4GHz, 5Ghz, USB storage NAS working with errors

Errors:
1. Since the introduction of ksmbd, I cannot save to an ntfs partition on the routers USB drive: wrong parameter.
2. DNS leak see: http://svn.dd-wrt.com/ticket/6020

Otherwise build is fine

Resolved:
1. Pushed DNS servers from VPN provider are used starting with build 41120, if you do not want that, add the following to the Additional Config of the VPN client:
pull-filter ignore "dhcp-option DNS"
2. Build 41174 has an improved VPN Policy Based Routing, it is now possible to use the VPN route command i.e. to route a DNS server via the VPN (in this way you will get rid of the DNS leak), see: https://svn.dd-wrt.com/ticket/6815#comment:1 , and for DNS leaks the second posting of this thread: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=318662
3. Another improvement on PBR is that local routes are now copied over to the alternate routing table so there is communication if you have unbridged VAP's and you can set the router's IP on PBR.
See: https://svn.dd-wrt.com/ticket/6821#comment:3
4. Starting with build 41174, the PBR has become more versatile, you can now use " from [IP address] to [IP address] ", so if you enter the following in the PBR field:
192.168.1.124 to 95.85.16.212 #ipleak.net, it will only route IP address 95.85.16.212 (which is ip leak.net) from my IP address 192.168.1.124 via the VPN everything else from this IP address will route via the WAN (this is just an example).
See: https://svn.dd-wrt.com/ticket/6822
Although this command itself supports routing per port this is however only available starting from K 4.17 so we have to rely on scripting for per port routing until then.
5. New OpenVPN TLS ciphers are added in 41308 see: https://svn.dd-wrt.com/changeset/41308
6. Starting with build 41304 you can now choose which TLS Key you want to use: TLS Auth or the newer/better TLS Crypt. See https://svn.dd-wrt.com/ticket/6845#comment:17
7. Builds from 41786 onwards, when using an OVPN server to connect to your local LAN clients, access might be prevented because of a patch which should solve a recent vulnerability ( see: https://svn.dd-wrt.com/ticket/6928)
This can be mitigated with the following firewall rule:

Code:
iptables -t nat -I POSTROUTING -o br0 -s $(nvram get openvpn_net)/$(nvram get openvpn_tunmask) -j MASQUERADE

When using WireGuard you can run into the same trouble,i.e. not being able to access your local LAN clients. For WireGuard this is the workaround:
Code:
iptables -t nat -I POSTROUTING -o br0 -s $(nvram get oet1_ipaddr)/$(nvram get oet1_netmask) -j MASQUERADE

This method described above also has security and logging concerns as all traffic has the same source address (your router)
An alternate method is using the following rule but it only works if the VPN or Wireguard interface is up and if your VPN or Wireguard interface goes down you have to reapply or run a continuous script checking/applying:
OpenVPN server:

Code:
iptables -t raw -I PREROUTING -i br0 -d $(nvram get openvpn_net)/$(nvram get openvpn_tunmask) -j ACCEPT

WireGuard:
Code:
iptables -t raw -I PREROUTING -i br0 -d $(nvram get oet1_ipaddr)/$(nvram get oet1_netmask) -j ACCEPT

This rule can expose your LAN side to the CVE attack, but if you have your IOT things separated and tight control over your LAN you should be good, if your LAN is hacked you have got bigger problems.

Builds starting with 41813 have an option button in OpenVPN and Wireguard for disabling the CVE-patch 14899


Big Thanks to BS!!

Does cpu freq scaling really help significantly? I suppose this can be done on the R7800 but I'm wondering if it's worth the effort.

Not sure what you really want answered Rolling Eyes

NO, NOT better than CPU set to performance (max CPU)
AND
All IPQ806x units are set to max CPU by default --- been that way for long time now. Cool

this is just a power saving feature, not more

my r7800 are wall-mounted and have no thermal problems at full CPU speed

CPU 43.562 °C / ath0 38 °C / ath1 34 °C


43°C @ idle is great

Everything is so awesome.

Still awesome.
