Created attachment 468362 [details] amdgpu-pro overlay The bug is related to this thread: https://forums.gentoo.org/viewtopic-t-1060214-start-0-postdays-0-postorder-asc-highlight-.html I have a multi gpu config, both of them are ati rx480. I really dont care about crossfire and increase the gpu performance using both of them, the problem is that when I have the 2 gpu in the system, vulkan dont work, works great with only one gpu connected. the error is: CreateSwapChain(): call to vkCreateSwapchainWSI returned an error I really dont know if its related to this error too: Xlib: extension "AMDGPU" missing on display ":0". direct rendering: Yes GLX_INTEL_swap_event, GLX_MESA_copy_sub_buffer, GLX_MESA_query_renderer, OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics GL_ARB_compute_shader, GL_ARB_conditional_render_inverted, Xlib: extension "AMDGPU" missing on display ":0". GL_KTX_buffer_region, GL_NV_blend_square, GL_NV_conditional_render, GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, Xlib: extension "AMDGPU" missing on display ":0". GL_KTX_buffer_region, GL_NV_blend_square, GL_NV_conditional_render, GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, GL_KTX_buffer_region, GL_NV_blend_square, GL_NV_conditional_render, this issue goes away too when I remove the second gpu of the system. I attach the overlay added to build amdgpu-pro - amdgpu-pro-dkms and I clone gentoo-sources too to avoid a dissapear of portage of my kernel
I don't know what I can possibly do from a distro perspective. Please file this upstream (https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/)
