Emulator

It's a random issue in the past. Unless you can trace down a particular build in which this becomes common, this will just be rolled into the dualcore problems.

The range you left is too wide, and I have doubts that this started on a particular build. Feel free to prove me wrong; it'd always be great to narrow it down and fix it.

I think this issue is related to Issue 7656.

I think this is what just happened to me. Here is the log file as of the time the GPU crash message box popped up (I haven't clicked OK yet as I write this). The last 7 lines are the ones generated in response to this crash. Also, this has happened multiple times in the last 15 minutes, but the game usually just resets instead of causing Dolphin to crash (that's what the earlier parts of the log file are, the game resetting on error instead of crashing Dolphin, though its probably the same error causing all of it). I'm currently running Dolphin 4.0-3186 (no more than a week or two old I think). I'm attaching a zip file with a screen shot of the crash dialog (over the game and a log viewer sidebar) as well as configuration files and any other files I think are relevant.

(written as I'm gathering files):
Some of the configuration files might have information in them from old versions of Dolphin or may not be used in this version of Dolphin (i.e. DSP.ini). I've been using Dolphin since 3.5 and I've just copied my user data from version to version. Also I apparently have two instances of Dolphin open right now, though one is just sitting at the game select screen and isn't doing anything at the moment.

Addendum to the previous comment. Just clicked the OK button and then had to click through 5 more crash dialogs. I've attached screenshots of all 6. After clicking through all of them, the game reset and continued to work just fine like it did every other time this happened (only this once has it triggered error dialogs). I've also included the additional log information generated from the crash (the extra 30 minutes between log entries is the time I spent making an error report while avoiding clicking the OK button on the first crash dialog. Another observation is that the game seems to go longer each time without crashing (the first couple times it crashed immediately on loading the title screen, later it was able to get to machine select, and then later crashed on loading a track (actually trying a race). I also apologize for the screenshots being so big. They were taken with print-screen and Word saved the entire image rather than the single screen I cropped it to.

Final post from me for now:
It just happened again and I didn't want to report it because I didn't want to spam the comments section, but the dialog said to report it. The game crashed again and after clicking through 6 more crash dialogs for the event, with the same log output as the last time even though the particulars changed (GPU FIFO crashed with a different opcode) a new dialog popped up reporting:

Negative fifo.CPReadWriteDistance = -224832 in FIFO Loop ?
Than can produce instability in the game. Please report it.

It's a Yes/No dialog box, so I'm not sure what I'm supposed to click but I ended up clicking Yes.

This crash seems to be happening fairly consistently (consistent in that it happens, not consistent in when) so if anyone wants me to test further I would be willing to do so. Just let me know.

Feel free to keep reporting this, it happens in regular dualcore too, so it's obviously a serious issue.

Alright. I've moved the images to imgur and I'm attaching the configuration files directly to this post.

Is there a way I could get more information about what is actually going on? I have the build released on the download page for this revision, but I'm not sure if I need a special build to have debugging features enabled to get more information. I'm just not sure what else I can report at this point that wouldn't be a variation on what I've already reported.

I think you should keep going backwards in builds, maybe bisect (try build 4.0-1600ish, see if it happens, if it does, go to 800, if it doesn't, go to 2400) until you find the first build that the behavior changed.

I've been testing and found this to be an issue as far back as Dolphin 4.0-100, though it isn't an issue in 4.0.2. Another interesting point is that it always resets (crashes the game without crashing Dolphin) on trying to load the title screen (it displays the logos and loads the save data just fine) the first time. However, letting it run after that may not reset the game. Alternatively, exiting the game (but not Dolphin) after the first reset and then starting the game again manually doesn't crash the game (the behavior is as if the game had remained running). In order to reliably reproduce the crash you need to exit Dolphin completely in between tests.

Tried some other configurations and found that enabling DSP-LLE with DSP-LLE on Thread seems to fix the problem more permanently up to at least 4.0-1601 (note that the only setting I changed was from DSP-HLE to DSP-LLE with JIT). Not sure why this is, but it may be that 3 threads competing for 2 cores alters the synchronization race a little. What is especially confusing is that this solution persists after reverting to DSP-HLE and completely exiting Dolphin. I'm going to try running through all of the tests again after rebooting my computer to see if there's any caching involved that's changing my results.

Fzero has a game timeout so any delayed in the GPU threads produce the Reset Loop, for example the shaders compilation, etc.

This is unrelated to shader compilation as far as i can tell. It can happen just sitting in the main menu.

I said "etc", anwyay what is "sync GPU" the old counters in OP or the new comex code?

Old stuff; it's skid_au's sync GPU. Comex's doesn't support F-Zero GX at all.

I never explicitly enabled sync GPU, so it should only be enabled for me if the game specific settings that come with Dolphin force it on (which I think only happens in some of the versions I tested on).

Since the issue goes so far back in revisions, I'm curious if the problem was created during the GPU rewrite that removed D3D9 and merged parts of the code for D3D11 and OGL.

That wouldn't have affected fifo; just how strenuous the GPU thread is on the actual graphics card.

Another report: Still on version 4.0-100. If I delete the cache files from the User directory the reset happens even with DSP-LLE enabled. Furthermore, even without restarting my computer it is again happening consistently.

This happens as far back as Dolphin 3.5-1936

I've been experimenting with this and I realized that I hadn't enabled Sync GPU because it has to be enabled manually in the game config (it isn't by default). Without Sync GPU, the crashing behavior happens on both the D3D and OGL backends. I enabled it on 4.0-3471 and the game seems to be stable, though with lower performance than Single Core mode as noted in the OP. However, I can still crash it at will by toggling the frame limiter with TAB. This applies to both D3D and OGL backends regardless of whether Sync GPU is enabled or not. Is this new behavior or has this already been dealt with? Looking at the pull request for Sync GPU it appears that F-Zero was already known to have problems to begin with. Should I keep investigating? If so, how should I proceed?

crash-free WITHOUT GPU sync in OpenGL as of 4.0-3496 -please confirm

Ok guys so have been carrying out more experimentation esp in light of all the CPU updates -I'm pleased to say (but would appreciate some input from others) that as of the latest build I no longer experience crashes in OpenGL at all without GPU sync (which still seems horribly broken for me when i do try it)

To state the obvious D3D still crashes left, right and centre...

also fast disc access seems to help slightly with the initial slowdown at the beginning of most levels...

Just tried without GPU sync with OpenGL in 4.0-3496 and it consistently resets on first load of the title screen for me. Tried playing a little bit and I just got the dialog box for GFX FIFO: Unknown Opcode and the other trail of dialog boxes I got in earlier reports followed by the game resetting. I can also still crash it at will by disabling the frame limiter with TAB. D3D also still has all the same problems as above, though it has been more stable for me so far (after the initial reset it only crashed when I disabled the frame limiter).

Should the ability to crash the game at will by just disabling the frame limiter be considered a bug? Also the log output isn't very helpful here for diagnosing what's going wrong, even with the minimum logging level set to the lowest shown and all loggers enabled. Besides general slowdown I'm not noticing any problems mentioned in the wiki page besides the crash from de-sync. Is there a way to get more log output from Dolphin's internals that would be useful or is there no way to log output that would be useful in diagnosing this?

The game tells us what is wrong in the log:

29:52:199 Src\HW\EXI_DeviceIPL.cpp:284 N[OSREPORT]: [warning] GP WAIT Timeout... (sending object 0/3)

The issue is that the CPU thread and the GPU thread are running at different rates unlike the real hardware. The game detects this and resets.

One possibility is that there is a sync'ing mechanism in the GC FIFO/Command Processor hardware that we have not discovered yet.

Hi guys some more details in case it helps -I'm still having a crash-free experience in OpenGL BUT only it seems because I have locked my cores(?)

Have a i7 980x/GTX580 with Dolphin locked to alternative cores (so like no hyperthreading) -I see utilisation across 5+ ccores, is this an OpenGL driver thing?

Sorry if this is vague, am at the limits of my understanding!

PS if I don't frame limit I too FIFO crash...
