Vulkan + Win10 x64 + Intel Skull Canyon NUC (Iris Pro 580) = Broken

[xhsmd]

I'm not entirely daft, so I'll try and help out as much as I can.

Intel Skull Canyon NUC (NUC6i7KYB) works perfectly on Linux (tested on Fedora 26, OpenGL and/or Vulkan, no issues). On Windows 10, Vulkan will not work.

Using the latest build (as at right now: 5.0-4337) and some previous builds, Dolphin will hang and eventually crash before anything is displayed.

Compiling and running Dolphin in debug, the last line of code before it eventually hangs and subsequently crashes is in ./Core/VideoBackends/Vulkan/ObjectCache.cpp Line 362/363:

Code:

VkResult res = vkCreateGraphicsPipelines(g_vulkan_context->GetDevice(), m_pipeline_cache, 1,
                                          &pipeline_info, nullptr, &pipeline);

Trying to follow the code from this point leads me to: /Windows/System32/DriverStore/FileRepository/igdlh64.inf_amd64_6d1fd205efa7f979/igc64.dll

Dolphin will not reach line 364:

Code:

if (res != VK_SUCCESS)

Eventually it will crash after pretty much consuming all available ram (in this case, 32GB).

The error message is as follows:

Code:

Unhandled exception at 0x00007FFD4F8EBBEF (ntdll.dll) in DolphinD.exe: 0xC0000005: Access violation writing location 0x0000000000000024. occurred]

PS: I'm only a hobbyist programmer. I've coded a fair few applications in C/C++ before but have never worked on any team based projects, only my own, and have never really used Visual Studio to it's full before. I can help diagnose this issue as much as possible but you will have to point me in the right direction (Basically, talk to me like I'm an idiot, tell me what to click and tell me what to copy and paste).

I think theres a known issue in Intel's Vulkan driver on Windows. None of the graphics devs can reproduce it though so nobody has looked into seeing if a workaround could be implemented because reporting driver bugs to Intel is impossible afaik

As it appears my system may be one of the ones affected, and as I have no real sensitive information on my Windows installation, if any graphic developers are interested in figuring this out I'm more than happy allowing them to remote my machine to try and work it out.

[shuffle2]

If you compile and run debug build of dolphin, visual studio should show you the callstack when it crashes. can you paste that here?
You could also use VS to create a dump (e.g. https://blogs.msdn.microsoft.com/debugger/2009/12/30/what-is-a-dump-and-how-do-i-create-one/ ) and then post a link here so someone can look at it.
However, since it is likely an intel problem, it may be the most we can do is find out what intel is doing wrong.

Dump will take a while for me to upload with the heap (56GB).

[shuffle2]

thanks for the info. could you post your igc64.dll, and also repaste the callstack after loading/showing symbols for ntdll? (right click on ntdll and load symbols. you may have to go into settings and enable the microsoft symbol server).
A dump without the heap is probably ok. fwiw it probably compresses well.

I've let it compress while at work. I'll get back to you with this info in ~8hrs time.

[shuffle2]

Thanks for the stuff. Here is the cause of the crash:

igc64.dll is causing the crash because it uses an uninitialized critical section object.

Code:

.data:000000018092CFD8 ; struct _RTL_CRITICAL_SECTION g_crit_sec_bad
.data:000000018092CFD8 g_crit_sec_bad _RTL_CRITICAL_SECTION <?>
.data:000000018092CFD8                                         ; DATA XREF: sub_180676E50+Ao
.data:000000018092CFD8                                         ; sub_180676E50:loc_180676F3Fo

sub_180676E50 is the only use of this object, and the function only calls EnterCriticalSection/LeaveCriticalSection.
As documented on msdn, these objects must be initialized (usually with InitializeCriticalSection): https://msdn.microsoft.com/en-us/library/windows/desktop/ms682608(v=vs.85).aspx


If you want, I could provide a build which patches in the correct functionality, but I would not want to add that hack to dolphin permanently. This is a problem Intel has to solve unfortunately. You could try to see if some drivers from their site are more recent and have a fix?

I wouldn't want you to go out of your way for something that is probably only affecting a minority of Dolphin users. I mostly use Linux on this machine where it works perfectly already. I would be lying though if I said I wasn't curious as to what the fix is.

I'm aware that Intel have really dropped the ball with their GPU drivers. I got this machine pretty much at release because I was/am interested in learning Vulkan. I'll have a look to see if there are any more recent updates for their other GPUs and see if that works.

Anyway, thank you for looking into this.
