I don't run anything more complicated than Kodi (which is simple) but hardkernel picked patches from me and report improvements with them for desktop-ish things
<pmjdebruijn>
ok, good to know, will take a close look tonight
<pmjdebruijn>
that's in teresting, given I was having some performance issues with lima as well, and lima has similar code
<pmjdebruijn>
chewitt: btw, wrt to that patch, there a Kconfig that should probably also should be adapted: select DEVFREQ_GOV_SIMPLE_ONDEMAND

pmjdebruijn I'm not the best a reading code, but I'm not sure the others (PERFORMANCE etc.) are supported
<chewitt>
Kodi isn't a heavy app, but I didn't see the GPU change from the minimum opp point to anything larger
<pmjdebruijn>
chewitt: I meant, you've changed the code to use PERFORMANCE, but the Kconfig doesn't enforce PERFORMANCE is compiled in, so there a possiblity for the kernel not to compile with merely the code change, and not the Kconfig change
<pmjdebruijn>
probably not likely in real world, but possible

ahh, okay
<chewitt>
the hack seems to work for Kodi .. I didn't get around to nagging panfrost folks about it yet
<chewitt>
(they need a break from me)
<chewitt>
(they already did much in Q4/20!)

btw, to what extent is LIMA dependant on Meson specific bits for stuff like vsync?
* pmjdebruijn
suspects vsync not to be working on Odroid C2

<narmstrong>
pmjdebruijn: if you see a picture on HDMI, vsync works
<pmjdebruijn>
ok?
<pmjdebruijn>
you mean as far as the meson parts are concerned, aside from lima
<narmstrong>
don't expect LIMA to have the same perfs as the ARM blob
<pmjdebruijn>
I don't

chewitt: would that performance governor hack work for lima too?
<chewitt>
asdf28 I didn't do much on GXBB/GXM recently so didn't look
<chewitt>
poking around on a GXBB box briefly the other night the Kodi GUI was quite snappy so I suspect it's running at max alreaady
<asdf28>
hmm okay
<asdf28>
some weeks ago, i found out that you can set the GPU frequency for lima via the command line
<pmjdebruijn>
asdf28: it does
<asdf28>
but sadly, it had no effect whatsoever
<pmjdebruijn>
the governor hack I mean
<asdf28>
pmjdebruijn: cool... for lima? so it did make a difference for you?
<pmjdebruijn>
I think so
<asdf28>
i had something happen where applications ran at 1 fps
<asdf28>
i don't know if it was the same for you
<asdf28>
but it wasn't always like that, it happened from kernel 5.9 and onwards
<pmjdebruijn>
my case wasn't that severe
<asdf28>
did you just try the hack with lima?
<pmjdebruijn>
yeah
<pmjdebruijn>
very briefly
<asdf28>
interesting that it made a difference, i'll try it too
<pmjdebruijn>
my benchmarking was rather quick, so I wouldn't testify in court :)
<asdf28>
btw, regarding the sound, there's a bug where you have no sound when you plug the HDMI cable in after you started the box
<pmjdebruijn>
ah, good to know
<asdf28>
just in case :-)
<pmjdebruijn>
I've experienced something similar with USB oddly enough, though I can't reproduce that now, so I might have been a kernel bug fixed already

btw, do any of the meson platforms have overscan handling on hdmi?
<pmjdebruijn>
so I can have a black edge around my output?

btw on my odroidc2 I'm also noticing that reboot usually doesn't work. some folks seem to think it might be related to the SD card
