00:00fdobridge: <gfxstrand> This is fun.... My kernel is reporting about 100x the VRAM used as I have on the card. 🤔
00:01fdobridge: <gfxstrand> This seems like not my bug
00:05fdobridge: <gfxstrand> Do we have a nasty leak somewhere?
00:39RSpliet: didn't you just download some extra RAM?
00:42fdobridge: <gfxstrand> Not that I know of.
00:42fdobridge: <gfxstrand> I find it a bit hard to believe that TTM is just miscounting.
09:23fdobridge: <tom3026> what cpu are you hitting those hangs with? this 13900hx was really unstable until i actually undervolted it lol. it was like it was hitting some thermal throttle and simply couldnt downclock fast enough and shit hit the fan
09:25fdobridge: <tom3026> the legion powersave/balanced mode mitigated it. but the "perf mode" i dead locked in mprime stress test in seconds, and had various crash and burns in just normal tasks until undervolt applied. this was with blob, have just about finally setup the install again so i can test nvk again on this 4080 :p
10:31fdobridge: <mohamexiety> yeah it's also possible that the hangs are due to unstability somewhere if nobody else can replicate them at all, but this is quite rare. given she mentions 18 cores, there's only one CPU that fits that criteria; the the 10980XE (or the 9980XE, but it's the same, really)
13:26fdobridge: <!DodoNVK (she) 🇱🇹> Why is gamescope support being locked behind ReBAR? 🐸
15:11fdobridge: <gfxstrand> Why does gamescope require ReBAR?
15:12fdobridge: <Sid> it doesn't, afaik
15:12fdobridge: <Sid> worked fine on my machine before I hacked ReBAR into it
15:14fdobridge: <gfxstrand> If you're asking why exposing the BAR heap is locked behind ReBAR, it's because the nouveau KMD doesn't do a good job at handling scenarios where we request lots of mapped VRAM. If we can fix that, I'm happy to expose it everywhere.
15:16fdobridge: <!DodoNVK (she) 🇱🇹> That's what I'm asking
15:45fdobridge: <gfxstrand> Ideally, nouveau would just migrate mapped stuff to system RAM if there's too much of it to fit in 256 MiB. In reality, it doesn't do a great job of that and I start seeing faults, hangs, and even the odd SIGBUS.
15:46fdobridge: <gfxstrand> It may be okay in practice and it's just my crazy CTS stress testing that's breaking it but I still don't fully trust it.
18:17Ilgaz: hey people, for some unknown time, nvidia 9400 brightness not being able to set issue is back. I had some issues so I am not sure when it has begun. putting backlight=native etc doesn't help too
18:18Ilgaz: I should switch to "vanilla opensuse kernel" to begin with I guess
18:46Ilgaz: bbl
22:03fdobridge: <airlied> Well nouveau doesn't really have visible vs invisible vram, you can map anything into the BAR using a page table, just not sure mgmt of that table is that good
22:23fdobridge: <gfxstrand> Yeah...
