Random freezes when booting a game on Lubuntu 18.04 #603

Closed verybadsoldier closed 5 years ago

verybadsoldier commented 5 years ago

I have a problem that all games (at least the 3 that I have tested) do freeze early just after booting. Sometimes while the Sega logo is showing, sometimes in the main menu and sometimes I even make it into the game. When it happens then retroarch just freezes hard. There is no log output and even a SIGTERM is ignored. I have to SIGKILL it.

strace is very busy before the freeze and then also just hangs up when it's happening:

Note that the last log line appears early and then there is nothing until it actually freezes.

Is there anything else I could provide to help out? Thanks!

fastpop72 commented 5 years ago

I had a similar bug using my hardware (i5, 12GB, Intel integrated graphics).

Every games freeze after some seconds (i tested only NAOMI games).

I solved on installing my environment on Debian 10 instead of Ubuntu Server.

flyinghead commented 5 years ago

If possible, try to attach to the frozen retroarch process using gdb and post a stack trace of the various threads.

verybadsoldier commented 5 years ago

I tried but sadly it behaves differently and crashes instantly after half a second:

flyinghead commented 5 years ago

This is because flycast uses SIGSEGV signals internally.

Execute handle SIGSEGV nostop noprint in gdb before starting RA.

verybadsoldier commented 5 years ago

Ok I see. This is it: https://pastebin.com/77f8B007

flyinghead commented 5 years ago

It looks like another Mesa deadlock. Many people seem to have this problem on various linux flavors. Not sure what causes this but it's clearly a driver problem.

Try upgrading/downgrading the Mesa version.

verybadsoldier commented 5 years ago

Hm, Ok I upgraded Mesa from 19.0.2 to 19.1.2 but the problem still persists.

Not sure if my first stacktrace was accurate since I used a VNC session so I did a new one (with new Mesa) but it looks identical to me: https://pastebin.com/RDbvnefQ

Yes, the problem is the same. The main thread (thread 1) is locked executing gl_swap(). There's no reason it would deadlock there unless there's a driver bug.

Most likely a duplicate of https://github.com/libretro/flycast/issues/232, that's a driver bug indeed, the only known fix is to set DRI to 2 in your xorg conf : 

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "DRI"            "2"
EndSection

Wow thanks, that fixed it! Not sure what the drawbacks of DRI2 vs DRI3 are but this works. Is is reasonable to hope that this driver bug will be fixed at some point?

Well, as mentioned in the issue above, that's a regression with flycast/reicast when moving from mesa-17. Sadly, intel gpus have poor linux drivers, they might have worse drivers on windows, and to be pragmatic : finding good workarounds for intel's misshaps is not really the job of small team of developpers like ours.

You can try bringing the issue to the mesa team but don't expect too much, the fix above is actually a recommendation from them when things go wrong with intel gpus (which happen with a lot of software).

As a drawback, i'm pretty sure dri2 is supposed to be a bit slower.

I'll close.
