<SpieringsAE>
it has been a while since I had the hdmi connected maybe some new plasma bug, I've been getting an odd bug on my work pc lately where one display stays black for quite a while
<SpieringsAE>
cursor is visible on it though during that time, so it is properly connected

SpieringsAE: turns out it was some local crap for a pre-release kwin, so it may or may not break in 6.5, I should check if mater is ok ig later..

akhilpo: I played a bit with the scheduler and idle latency (with pm_qos_resume_latency_us), and I realized it helped a lot on the animations stutter on hyprland, and I think I figured out a better scenario to replicate the problem
<anthony25>
I tried scx scheds, and I realized that they lowered the stutters
<anthony25>
but the power consumption pretty much doubled on most of them, that or it was really laggy
<anthony25>
I understood that it was linked to the idle QoS latency, that some scheds set
<anthony25>
so I tried to set it manually, and setting pm_qos_resume_latency_us to lower than 1000 helps (but it makes it harder for the cores to idle, if I understand correctly)
<anthony25>
so what I found to work the best, is using scx_lavd in balance mode, and setting a core preference list to 1 core, and lowering the pm_qos_resume_latency_us for this core
<anthony25>
sorry: I meant setting a core preference to: "8,9-11,4-7,0-3", so it'll prefer core 8, and I bias the idle time for it
<anthony25>
also, I realized that the stutters happen only when there is a "heavy" app to render
<anthony25>
and they seem to happen only for workspace switching
<anthony25>
so it happens when I have firefox on one workspace, thunderbird on another one, and switching between the 2 creates some CPU load by the thunderbird or firefox process
<anthony25>
I'll try to replicate that on gnome, but it didn't seem to happen last time I tried
<anthony25>
could it be that the slim 7x set a high qos idle latency?
<anthony25>
also, using lavd (with the settings I listed above) doesn't increase the power consumption, it seems to be the same or lower than with EEVDF

<anthony25> could it be that the slim 7x set a high qos idle latency? <<< I mean, it doesn't seem to be the only problem, I still have way less stutter using lavd than with EEVDF and a low qos idle latency
<anthony25>
and it's interesting with thunderbird/firefox, if I switch to an empty tab, the animations don't stutter

hmm, /sys/devices/system/cpu/cpu*/power/pm_qos_resume_latency_us is all 0 for me ... idk if something in userspace/gnome is adjusting those?
<anthony25>
robclark: by default, for me too, but 0 is using the default platform value (I don't know what sets it?)

Hmm not available?
<maz>
definitely available here for £480... Guess I need to click the button...
<JensGlathe[m]>
aaargh why
<JensGlathe[m]>
you do have a devkit no
<JensGlathe[m]>
its €800 or so here
<maz>
I do have a devkit. but that's to replace my home "pile everything that runs" box.
<JensGlathe[m]>
And I had it in the cart maybe 4 times or so
<JensGlathe[m]>
That's a good excuse tbh

let us know how it is.. a nuc type form factor would probably be more useful for CI farm..

robclark: Probably the 0 values you see for CPU nodes could be due to the hardened CPU dcvs. I think Oryon cores have hw implementation of dcvs.
<akhilpo>
Yeah, if cpu idling is very aggressive, that can cause issues.
<robclark>
hmm, could be.. I've not looked closely at cpufreq on these things

as soon as i finish grabbing logs for development, i nuke it and replace it with linux
