Description Paul le Roux 2016-05-23 10:32:43 UTC

When calling vkEnumeratePhysicalDevices it ends up failing at the ioctl call within anv_physical_device_init. It correctly opens the device /dev/dri/renderD128, but then fails with invalid argument when it tries to get the chipset id.

This is run on a i7-3630QM with a HD4000. There is also a GTX 675MX present, but it's not used.

Im running an updated Arch-Linux system (23 May 2016)

I build mesa with debug enabled and used the intel_vulkan library, but when trying to run any vulkan application (like vulkaninfo) it fails with 

anv_device.c:77: failed to get chipset id: Invalid argument (VK_ERROR_INITIALIZATION_FAILED)

Can you try it with the wip/anv-multi-device branch on my freedesktop.org:

https://cgit.freedesktop.org/~jekstrand/mesa/

It has a couple of patches that *should* let it work even if there are multiple GPUs in the system.

Running it with J. Ekstrand git branch:

I just get this warning

WARNING: Ivy Bridge Vulkan support is incomplete

The cube and triangle demo works, but when running vulkaninfo

vulkaninfo: anv_formats.c:268: anv_get_format: Assertion `vk_format_aspects(vk_format) == VK_IMAGE_ASPECT_COLOR_BIT' failed.

Although I think this is now a seperate issue.

Cool.  I just pushed the multi-gpu patches.

Yes, and I just fixed it!  I'm closing this bug now.  If you continue to have issues, please file them under a new bug.
