<tomeu> tlwoerner: do you refer to warnings in the kernel, or in userspace?
<tlwoerner> tomeu: give me a sec to re-create them... i believe they were kernel, perhaps complaining about memory (?)
<tlwoerner> interesting... the previous image had upstream kernel.org linux-5.4.2, this new image has linux-5.4.16. i'm not seeing issues with mpv-0.32.0 (maybe i have to do more with the system before they show up?)
<tlwoerner> i have one or two from chromium-79.0.3945.117

<tomeu> tlwoerner: you may want to try with this branch: https://gitlab.freedesktop.org/tomeu/linux/commits/v5.5-rc5-panfrost-fixes
<tomeu> it has proved quite stable in my local testing, and it's what we are using in CI
<tlwoerner> tomeu: sounds good, thanks!
<tomeu> tlwoerner: np, I'm curious about how it will work
<nhp> Did those fixes make it into final 5.5?
<tomeu> nhp: not sure about the last one
<nhp> Been running 5.5 on my Pinebook Pro since it came out, there was a conflict with those patches when I tried to apply them so I didn't
<nhp> I should've probably looked into what that conflict actually was...

<bbrezillon> tomeu, tlwoerner, nhp: if you hit this warning that's a sign that something else is going wrong (job timeout), but yes, we should find a solution for that one

<alyssa> tlwoerner: woo!
* alyssa wonders why all the bugs seem to be in the newer kernels
<alyssa> I don't think I've ever hit a bug relating to panfrost kernel in 5.2
<alyssa> of course it's missing some shiny features, I guess growable and separate as adds a ton of complexity

<HdkR> Hardkernel's ODROID-Go Advance is for sale finally. So I nabbed a handful :D
<HdkR> Cute tiny Bifrost

<robmur01> aww shucks, that means I have to actually address the "I want one but I really don't need one" conundrum now :P
<alyssa> Pff
<HdkR> :D
<tlwoerner> tomeu: i get a kernel oops when booting :-( [ 4.199878] pc : mdiobus_get_phy+0x4/0x20
<robmur01> tlwoerner: that should be fixed as of a week or two ago
<robmur01> yup, looks like it's filtered through to stable too
afaerber has quit [Read error: Connection reset by peer]
<tlwoerner> robmur01: yes! much better :-)
<tlwoerner> tomeu: looks like you're missing a critical patch ^
afaerber has joined #panfrost
<tlwoerner> tomeu: https://gitlab.freedesktop.org/tomeu/linux/commits/v5.5-rc5-panfrost-fixes doesn't change anything wrt gpu sched timeouts, in fact if /feels/ like there's more of them (e.g. i wasn't getting any with mpv, now i am again)
<tlwoerner> bbrezillon: would you like me to try applying that patch series?
<bbrezillon> tlwoerner: they should have been all applied except patch 1 and 9
<bbrezillon> sorry, 8 not 9
<bbrezillon> tlwoerner: you're testing 5.5, right?
<tlwoerner> yes, tomeu's branch at https://gitlab.freedesktop.org/tomeu/linux/commits/v5.5-rc5-panfrost-fixes (with the mdiobus patch on top)
<tlwoerner> xserver: 2_1.20.6
<tlwoerner> mesa: 2_19.3.1
<tlwoerner> bbrezillon: in tomeu's tree i see patches 1, 5, 4, 3
<bbrezillon> make sure patch 7 is applied
<tlwoerner> bbrezillon: is there another tree i could try?
<bbrezillon> but it should normally be part of 5.5 (probably not in -rc5 though)
<bbrezillon> vanilla 5.5?
<bbrezillon> unless you already tried and it didn't work
<tlwoerner> okay
<bbrezillon> what's the platform again?
<bbrezillon> I can probably try to update myself and see how that goes
<tlwoerner> no, not yet. i had tried 5.4.16, then tomeu's tree
<bbrezillon> ok, then yes, try 5.5

<tlwoerner> bbrezillon: nice! yes in 5.5 (working from the linux-5.5.y branch) the kernel dumps are gone (job timeouts)
<tlwoerner> mpv has no issues
<tlwoerner> chromium still has a lot of "Unhandled Page fault in AS0 at VA 0x0000000000000000", but there's definite improvement :-)

<bbrezillon> but I doubt it will solve this problem

<tlwoerner> confirmed (issues still there after patch 8, but it does *feel* like there are fewer)
