Hehe, but the fun fact is that it works
@facboy sorry for the tag... do you think these values are correct?

Anyway no idea why the DUMB method is a direct way to get the current freq of the system... It does never fail.... for some reasons....
it seems a bit odd it got slower? your first run at 1.4g it hit 750mib, then at 1.7 it only did 640mib and after that everything seemed a bit slower.
fwiw mine hits 780mib at 1.7g, i'm on a few months old master build - have my own custom branch but its ~r17783.
is memcpy and memblock important? this with the l2 workaround reverted... will check if i gets different results with that up... Still can't understand why dumb values are correct but memcpy aren't...
Quiet here, any update on the scaling issue/crash?
My R7800 just passed 100 days of uptme with minfreq raised to 800Mhz... so I have to say it's stable as a rock with the workaround.
I'm also using the ath10k driver and firmware-5.bin_10.4-3.9.0.2-00156 FW from QCA.
I've been running mine with the performance governor always at max 1.7GHz for years without any problems. Not sure it's worth the constant scaling, it's not a phone running on battery and the temp increase is negligible 2-3C in my experience.
Also on mainline driver and firmware
Now, I hope someone will figure out a fix for the AQL issue ... I'm stuck on 21.02.1 because of it
Hello
I'm facing a constant kernel oops with IPSec/Strongswan on 5.15 (since .33).
The crash occurs when doing a NAT mapping event (client switches to another IP) in xfrm part of the kernel: https://github.com/strongswan/strongswan/issues/992
I spent something like 24 hours on this issue and I now think it might be related to some patches applied on the kernel.
Does "someone who knows" could please take a look ?
To keep the temps down, if you're running performance governor or other higher clock speeds, I noticed that putting the router on a "vented" surface instead of a flat table helps quite a lot with the temps.
I have mine on a window sill that has gaps between the wood pieces.
My router is placed on a Foot stove (Netherland's model) because then I could use the holes on the top to route power and network cables for 2 SBCs stored in it.
I also think it looks kind of 'cute'.
Never thought (about) that it would (also) help with cooling
If anyone wants to test i'm currently cleaning the 5.15 patches
(so to test this enable testing kernel version)
I'm trying a different implementation of the cache scaling driver... No fixes about the power loss but it's just a cleanup where i replace patches with upstream version.
Would love some feedback
https://git.openwrt.org/?p=openwrt/staging/ansuel.git;a=shortlog;h=refs/heads/ipq806x-cleanup
no idea if it's luck but the changes are producing more uptime...
would love more testing tho....
Hey @quarky, I noticed sometimes my Wifi becomes very slow, it's hardly usable, it goes away after maybe 5-10 minutes. Sounds familiar?
I see this when my R7800 is running the virtual time-based airtime scheduler. Since it was reverted back to the round-robin scheduler plus enhancement patch my R7800 appears to be good.
Were there any other workaround other than patching? I don't quite remember.
I don't feel like poking around too much since the build is very stable apart from the occasional wifi slowness.
Restarting WiFi clears up the problem for me, so maybe you may want to write a script to restart WiFi every day?
Just upgrade your router to 22.03 RC5. It should fix your WIFI issue.
Yeah, it does for me too, I thought about it.
@vochong Hmm, are you sure? The problem lies in the airtime scheduler, is that fixed now?
EDIT: I guess so... maybe it's this fix: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=6d49a25804d78d639e08a67c86b26991ce6485d8
And another fix today for multicast-induced latency bug:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=ec9f82fa18c7c8deb4875152d7907855d186f4c6
Initial impression is that Wi-Fi is behaving nicely after those changes. Feels more responsive too.
Let's hope the uptime will be as good as the last bulld I had.
@shelterx Good to hear.
I hope someone can persuade @nbd to commit the fixes to 21.02 branch as well, so the WIFI in the next 21.02.04 release will be good again. As of now, 21.02.1 WIFI is the only good one in the 21.02 series, because the 21.02.2 / 21.0.2.3 releases had this VTBA scheduler commit:
