@kevindd992002 as long as you install 4.9.0.2 or 4.0.24 you get it activated.
Or wait a few days for forthcoming releases 4.9.0.3 & 4.0.25 which will enable core boost as well as providing the ability to disable it in BIOS.
Well, I already have 4.9.0.2 since two weeks ago so I think I'm good. I'll still wait for 4.9.0.3 main release and update as necessary. My pfsense APU2C4 boxes are for home-use only anyways.
-
Maybe I've missed, but as far as you know what will be the difference concerning this between 4.9.0.2 and 4.9.0.3?
-
@qinn All APU2 open firmware source is on github.
Release notes for mainline are here ... github PCEngines mainline changelog
NB v4.9.0.3 hasn’t been released yet... we have to be patient and allow 3mdeb to go thru their full release cycle
-
@dugeem Thnx for pointing that one out for me, I did not know there were "Unreleased" notes in the change log.
-
PC Engines / 3mdeb have released new coreboot firmware:
- mainline v4.9.0.3 (link https://pcengines.github.io/#mr-20)
- legacy v4.0.25 (link https://pcengines.github.io/#lr-17).
Both now offer ability in sortbootorder to disable Core Boost (default is enabled).
v4.9.0.3 also includes some additonal firmware fixes and support for SMBIOS memory capability types 16 & 17. The command
dmidecode -t 16 -t 17now works as expected on APU2 with 4GB.
Installed mainline v4.9.0.3 on my test APU2 with no issues.
-
Thanks for the update, I will install it asap.

SMBIOS memory capability types 16 & 17
Where does one use "SMBIOS memory capability types 16 & 17"?
-
@kevindd992002 For informational purposes only with dmidecode. Arguably this should have already been in the firmware but since it took time for 3mdeb to get ECC working (due to lack of AMD documentation) it probably hasn’t mattered.
-
How does the APU2C4 with the new BIOS compare to a Fitlet2 J3455? Does anyone know the boost clock that the APU will get up to now? Forgive me if I missed this info earlier in the thread.
-
With AMD CPB enabled in latest APU2 BIOS a lightly loaded (i.e. no more than single core active) APU2 CPU will boost from normal 1.0Ghz up to 1.4GHz. In the real world the gain is less - around 20% (see 3mdeb tech notes https://3mdeb.com/firmware/amd-cpu-boost/).
The quad core Celeron J3455 CPU has a base frequency of 1.5GHz and boosts to 2.3GHz - this would suggest it should offer ~50% higher performance than the AMD GX-412TC. Benchmarking would be required to confirm this.
However before selecting router hardware there are many other considerations apart from just CPU performance. EG. bandwidth, budget, form factor, interfaces, storage etc

Hi, I made the update on my APU2C0 board to coreboot legacy ver. 4.0.25 and after 2 days everything works fine - the only thing that I can see is that the CPU temperature is slightly lower (4-5°) than before the update (same environment conditions). Maybe it is in context of AMD CPB activation.
Have a fine Weekend,

fireodoYes, the CPU can now enter C6 idle-state as well when needed which is a deeper power saving state. More power saving = less heat.
-
Is it useful to enable PowerD now?
-
@qinn No. CPB is not describe in ACPI so, powerd doesn't know.
-
Thanks

Does anyone else use the gwled package for the other 2 lights on the front?
I noticed that it’s using massive amounts of CPU, pushing the load average well above 20. Even disabling doesn’t fix it, only removing the package helps. Below is only a snippet of "px auxw", there are still many more processes of the same.

Hmm, odd. Actual CPU time on those processes is all pretty small though. You see it generating those everytime at boot?

Is it a best practice to disable powerd then?
-
Powerd doesn't do anything on the APU anyway, there's no driver for cpufreq to use.
Mar 17 17:48:47 php-fpm 92195 /system_advanced_misc.php: The command '/usr/sbin/powerd -b 'hadp' -a 'hadp' -n 'hadp'' returned exit code '69', the output was 'powerd: no cpufreq(4) support -- aborting: No such file or directory'Steve

Hmm, I’ll have to check what it is at boot. I haven’t put much time into investigating it. Looking at the SNMP though, this is the first time the CPU has dropped down (after uninstalling the package). So, I guess it starts up pretty quick after boot since I don’t even see a dent in the SNMP.
Just watching “top”, it seems to come in bursts, like every 10 seconds for 5 seconds long for example.
A wild guess is that that’s how often it polls the gateways.I just re-installed pfSense from scratch, not restoring any backups, and it still does it.
Since there’s not much to configure, I assume anyone could reproduce it. If not, I’m really curious as to what’s so special about my system.
You can basically choose what the last 2 lights are, which I have as:
2 - WAN_DHCP4
3 - VPNI've made a new topic for this here
