Description LunarG 2019-02-06 21:45:03 UTC

[Hardware Info]
--Graphics Card--
[AMD/ATI] Ellesmere [Radeon RX 470/480] (rev c7)

--CPU Info--
Intel(R) Core(TM) i7-6700K CPU @ 4.00GH

[Sofware Info]
--Mesa Version tag--
mesa-19.0.0-rc1 and mesa-19.0.0-rc2

--llvm version--
7.0.1

--Kernel Version--
4.10.0-38-generic

[Problem Description]
Trying to run any of the Sascha Willems samples (https://github.com/SaschaWillems/Vulkan) or LunarG's Cube examples from the SDK (vulkan.lunarg.com) will freeze the system.

I've tried both building with both Meson and Autotools, with the same result. Am I missing a requirement or could something be out of date?

Possibly related to bug https://bugs.freedesktop.org/show_bug.cgi?id=109543

Comment 2 Bas Nieuwenhuizen 2019-02-06 22:57:32 UTC

Say I have a computer with similar GPU sitting around just for testing.

What would be the way to get to a similar software setup? What distro do you use, what is your compiler, where did your kernel come from and how did you compile mesa?

Comment 3 LunarG 2019-02-06 23:03:53 UTC

--Distro--
Ubuntu 16.04

--Kernel from Ubuntu's PPA--
https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/

--GCC version--
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609

Compiled Mesa using autotools with the following command:
./autogen.sh PKG_CONFIG_PATH=/opt/Mesa/lib/pkgconfig:/opt/Mesa/share/pkgconfig --prefix=/opt/Mesa --with-dri-drivers="radeon" --with-gallium-drivers="radeonsi" --with-platforms="x11,drm" --with-vulkan-drivers=radeon --enable-autotools --enable-dri3

Comment 4 LunarG 2019-02-07 17:10:15 UTC

I'm also seeing this same system crash on Ubuntu 18.04.1 using Radeon R9 380 card.

Happens when trying to run Sascha Willems Bloom sample.

Comment 5 Samuel Pitoiset 2019-02-11 08:28:47 UTC

What kernel version do you have on 18.04.1 btw?

Comment 6 Samuel Pitoiset 2019-02-11 15:05:21 UTC

Does it work with mesa 18.3.3?

Comment 7 LunarG 2019-02-11 16:56:29 UTC

> What kernel version do you have on 18.04.1 btw?
It's 4.15.0-45 generic

> Does it work with mesa 18.3.3?
Yes, I'm not seeing any problems running any Vulkan apps

Comment 8 Samuel Pitoiset 2019-02-11 17:18:36 UTC

Can you bisect?

Comment 9 LunarG 2019-02-12 00:17:05 UTC

After bisecting, it looks like commit f425d9ee74 is the first bad one.

I only used llvm-7 when trying to bisect.

Comment 10 Samuel Pitoiset 2019-02-12 07:30:23 UTC

Interesting, thanks for bisecting. I will investigate.

Comment 11 Samuel Pitoiset 2019-02-12 07:53:21 UTC

Can you try this patch https://patchwork.freedesktop.org/series/56522/ ?

Comment 12 Samuel Pitoiset 2019-02-12 07:59:35 UTC

Please, try v2.

Comment 13 LunarG 2019-02-12 16:31:35 UTC

Yes! this patch worked for me on my Ubuntu 18.04 - AMD R9 380 system! I will check with my other AMD systems today.

Comment 14 Samuel Pitoiset 2019-02-12 16:39:36 UTC

Fixed.

Thanks for confirming. I guess it should also work on Ubuntu 16.04.
