Vulkaninfo's log

Description of problem:
Mesa fails to load the vulkan driver on Intel HD630 integrated graphics (and possibly on AMD GPUs too).

Version-Release number of selected component (if applicable): 
vulkan-loader-1.2.148.0-1.fc33
vulkan-loader-1.2.148.0-1.fc33.i686

How reproducible:
Everytime you run vulkaninfo, it'll show the following errors:
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_intel.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_radeon.so: wrong ELF class: ELFCLASS32
INTEL-MESA: warning: Performance support disabled, consider sysctl dev.i915.perf_stream_paranoid=0 

Running an application like PPSSPP, which supports Vulkan, will fail to load its Vulkan renderer, and it'll default to OpenGL.

Steps to Reproduce:
1. Run vulkaninfo

Actual results:
Vulkan drivers are not loading.

Expected results:
Vulkan drivers should load, and vulkaninfo shouldn't show those errors.

Additional info:
Tested with Fedora's 33 Beta version, in X11 and Wayland Gnome sessions. I have both 32-bit and 64-bit packages installed due to Wine requiring at least the 32-bit one.

According to a different bug report that I've came across, (https://github.com/ValveSoftware/steam-for-linux/issues/7368) the vulkan drivers are not working due to a regression in the Vulkan-Loader package from Khronos, which has already been fixed, apparently, in a newer version.

does the package attached to this help?

https://bodhi.fedoraproject.org/updates/FEDORA-2020-76707d83ef

I've built the 1.2.148.1 sdk release.

Still not working, same error:
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_intel.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_radeon.so: wrong ELF class: ELFCLASS32
INTEL-MESA: warning: Performance support disabled, consider sysctl dev.i915.perf_stream_paranoid=0
Comment 5 Dave Airlie 2020-10-08 04:23:34 UTC 
So doesn't seem like the same bug reported in valve then, since the sdk release should fix it.

the wrong ELF class errors are fine, they shouldn't cause any issues
and the INTEL-MESA warning is fine.

Does vulkaninfo fail to display anything or is it just PPSPP?

Just tested vkcube, the cube is displayed correctly and the output shows the same warning: "INTEL-MESA: warning: Performance support disabled, consider sysctl dev.i915.perf_stream_paranoid=0". 

Now if I add the flag --validate to vkcube I get this, but the cube is still displayed correctly:
ERROR : GENERAL - Message Id Number: 0 | Message Id Name: Loader Message
	/usr/lib/libvulkan_intel.so: wrong ELF class: ELFCLASS32

	Objects - 1
		Object[0] - VK_OBJECT_TYPE_INSTANCE, Handle 0x557dd7bcbe40

ERROR : GENERAL - Message Id Number: 0 | Message Id Name: Loader Message
	/usr/lib/libvulkan_radeon.so: wrong ELF class: ELFCLASS32

		Object[0] - VK_OBJECT_TYPE_INSTANCE, Handle 0x557dd7bcbe40

INTEL-MESA: warning: Performance support disabled, consider sysctl dev.i915.perf_stream_paranoid=0

I've also tried this tester https://github.com/srmojuze/Refresh2025, which also displays correctly and shows only the Intel warning. 

Could this be a bug in PPSSPP?
