Thanks for the update. I'm glad to see I wasn't imagining things or a user/hardware issue on my end. When Ubuntu updated the mesa packages to 17.2.2 I made sure apport had the extra packages installed it needed. I also manually installed the 4 vulkan ddbug packages before running the vulkan-smoketest. Apport kicked in and auto-reported it. Hopefully that generated report helped since it does a far better job that my first attempt.
After I rebuilt the Ubuntu vulkan-utils package and used quilt to restore the amd mesa source but was unable to rebuilt mesa for the mesa vulkan drivers so was unable to test them. I had observed what the patch was doing and came to the decision that radv was being disabled by design. Thats why I didn't report upstream I didn't want to waste dev time for what appeared to be a packaging choice. My apologies for that. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1720890 Title: vulkan-smoketest segfaults steam vulkan games segfault Status in mesa package in Ubuntu: Triaged Status in mesa source package in Xenial: New Status in mesa source package in Artful: New Bug description: $ lsb_release -rd Description: Ubuntu Artful Aardvark (development branch) Release: 17.10 $ apt-cache policy mesa-vulkan-drivers mesa-vulkan-drivers: Installed: 17.2.1-0ubuntu1 Candidate: 17.2.1-0ubuntu1 Version table: *** 17.2.1-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu artful/universe amd64 Packages 100 /var/lib/dpkg/status Easily reproducible : apt-get install mesa-vulkan-drivers apt-get install vulkan-utils Open a terminal type vulkan-smoketest instead of a glxgears type window it will segfault. message from kernel.log: Sep 29 16:23:53 Tardis-1 kernel: [17709.532915] vulkan-smoketes[11798]: segfault at 0 ip 00007fed61a17914 sp 00007ffedcb8f850 error 6 in libvulkan_radeon.so[7fed619ab000+18b000] syslog: Sep 28 10:38:13 Tardis-1 kernel: [18292.174313] vulkan-smoketes[13385]: segfault at 0 ip 00007f62705a7914 sp 00007ffd0edc6260 error 6 in libvulkan_radeon.so[7f627053b000+18b000] What should happen is a glxgears like window will open and render properly instead of segfaulting. It appears that the culprit is an old or broken libvulkan_radeon.so provided by mesa-vulkan-drivers. As a test I renamed the old lib and dropped in a newer version from oibaf's ppa. smoketest now passes steam's The Talos Princible and Mad Max now work properly in Vulkan mode as well instead of segfaulting. This issue is also present on Zesty and fixed in both Oibaf's and Padoka's ppa's since April back when they were rolling 17.2 mesa. I have no idea if libvulkan_intel.so also needs updating no hardware to check.
