Vulkan Issues / Discussion

[DrChat]

Note: Add the flag --gpu=vulkan to enable the Vulkan backend!

@krzysztof860 - Can you attach the log file as well?

[krzysztof860]

@DrChat Here you go - http://www94.zippyshare.com/v/jVNNgujm/file.html

[DrChat]

Neat - this looks like a new crash now.

[dbz400]

thanks @DrChat

[DrChat]

Okay - AMD is gonna be on hold til Monday.

I think this crash was posted before, but I can't find it right now.

AMD people - Try it again with 75908a9865b27b2eeaa21a15e3b14c9777b00d56.

[sephiroth99]

Tried 9abfc52 still crashes at the same place.

I had tried the SPIR-V validator before, it did not find any issues; it is still very much a work in progress.

I will upload the newly generated shaders to the AMD thread.

[DrChat]

@sephiroth99 Alrighty - if you want you can take over that thread and I'll keep an eye on it.

[DrChat]

Neat - AMD is no longer crashing as of 14a6fd838a362031195de05a37fafd0941e689a9.

[DrChat]

@Gh0stblade Which games?

[SakataGintokiYT]

@krzysztof860 @woody2014 @Gamedev1909

Try latest build

[woody2014]

Good job it`s not crashing But have a blank screen.

[Gh0stBlade]

@DrChat Nevermind, no crashes. Looks like Github desktop app didn't properly pull down the latest commits.

@woody2014 Same here, just black screen.

[kkthxbye-code]

@DrChat - Can confirm that AMD doesn't crash anymore, but that it only shows black screen. Tested Banjo and Kazooie and Bomberman. They both play audio and accept input, just no video output.

[DrChat]

Wonderful - Someone with experience in renderdoc, can you capture a trace and start analyzing it? Launch Xenia with renderdoc using these flags: "--flagfile=scratch/flags.txt --vulkan_primary_queue_only=true"

When in-game, press F4 to capture a trace and close Xenia after it's finished writing it.

I can't do anything with the tracefile from here, so don't upload it.

[woody2014]

can we open a file in the vulkan backend then trace file.

[kkthxbye-code]

@Gamedev1909 - did you build it yourself? Otherwise you wont have the flags.txt file and it wont open. I managed to generate the trace, but renderdoc can't open the file, so I'm probably doing the wrong. I'm not really qualified to debug it anyway, but if you have any insight into why it wont open (says wrong magic header) @DrChat ?

[DrChat]

Nope. Still need someone competent to run a trace on an AMD card.

[ikki84]

Tested with 16.7.2 Hotfix, still the same. Radeon R7 200

[RenegadeSaiyan]

So now all Xenia does with Vulkan on AMD is Crash. GG AMD

[ikki84]

Tested again with Minecraft. Crashed after load the file.

-Radeon R7 200 -Driver 16.7.3 AMD Crimson Edition 28/07/2016 -Xenia build f81a99e 29/07/2016

[RenegadeSaiyan]

I tried some games that were proven to work, same result.

[RenegadeSaiyan]

I tried Sonic 2006, And Naruto Storm 2

[DrChat]

AMD people: I'm working on the crashes and blackscreens - be patient.

[SakataGintokiYT]

@DrChat

Progress :)

[SakataGintokiYT]

@Gamedev1909 Build from appveyor https://ci.appveyor.com/project/benvanik/xenia/build/1.0.451-master/artifacts

[Gh0stBlade]

@SakataGintokiYT

I get some exception here (AMD): xenia.exe!xe::gpu::vulkan::CachedRenderPass::CachedRenderPass(VkDevice_T * device, const xe::gpu::vulkan::RenderConfiguration & desired_config) Line 441 C++

Vulkan backend in a nutshell: https://youtu.be/68ugkg9RePc

[SakataGintokiYT]

@DrChat look at this : [Work around semi-broken dual-source blending on AMD.] / Dolphin https://github.com/dolphin-emu/dolphin/pull/3935/commits/e253a1673905b0b7df1fc59035b416c53b6d8d85

[sephiroth99]

I think the current issue with Vulkan crash on AMD is due to this (extracted from Vulkan spec here):

Multiple attachments that alias the same memory must not be used in a single subpass

I tried to separate the 4 color attachments into 4 subpasses, and the subpass create command does not crash anymore. Now, of course the rest of the code is not made for 4 subpasses so I had other issues e.g. dependencies, but the crash is due to the single subpass I think.

[krzysztof860]

Sorry for off-topic, but @DrChat someone wants to give you a R9 270X (2GB) https://www.reddit.com/r/xenia/comments/4y25ag/help_with_donating_a_gpu_to_the_xenia_devs/

[MrSapps]

I would assume he wants a full system, ripping out a working gpu in your own personal system with one some randomer has sent you to fix 1 issue probably isn't a great idea :s

[SakataGintokiYT]

@DrChat Progress !!! Xenia Vulkan build : [9457c63] _Video : https://www.youtube.com/watch?v=GUzDHodfmE4_

[Margen67]

I hope DX12 is added anyway so the speed can be compared to Vulkan.

[D1SMBD1D]

All NFS games using EAGL4 (Most Wanted, Carbon and Prostreet) crash at startup on Vulkan despite being close to playable on OpenGL Here's the Carbon log for example

[ikki84]

any news?

[NuclearC]

amd released new drivers that 'supports' glsl 4.5

[Razzile]

only a year or so too late lmao

[ikki84]

I will update the driver and test here.

Tested: still the same results

[Margen67]

[NuclearC]

anyone thinks to write D3D12 back-end for Xenia?

[gibbed]

The Vulkan backend is a work in progress.

[NuclearC]

but fcking DirectX 11 is faster than Vulkan

EDIT: here is some benchmark http://arstechnica.com/gaming/2016/02/vulkan-benchmarks-a-boost-for-amd-and-nvidia-but-theres-work-to-be-done/

[gibbed]

If you think so, feel free to implement a DX11 or DX12 backend yourself.

[NuclearC]

i didnt say i can do it better, but i want to understand why @benvanik removed DX11 backend from start

[gibbed]

Because DX11 was not meeting the demands of the emulator.

[NuclearC]

btw im getting 'Access violation reading location' exception on this line when using Vulkan on AMD driver:

return disp->CreateRenderPass(device, pCreateInfo, pAllocator, pRenderPass);

Thats the line 1653 in file 'trampoline.c' function vkCreateRenderPass which is called from CachedRenderPass(...) Here is the image:

What can i do to fix this?
