That got me close enough, mine is Ironlake.

The driver emits a warning chirp if the chipset isn't fully supported,
and will refuse to initialize on devices that are not supported at all:

dmt:~/fedora/anvil/anvil% grep -A13 -- '->is_haswell' src/vulkan/anv_device.c
   if (device->info->is_haswell) {
  fprintf(stderr, "WARNING: Haswell Vulkan support is incomplete\n");
   } else if (device->info->gen == 7 && !device->info->is_baytrail) {
  fprintf(stderr, "WARNING: Ivy Bridge Vulkan support is incomplete\n");
   } else if (device->info->gen == 7 && device->info->is_baytrail) {
  fprintf(stderr, "WARNING: Bay Trail Vulkan support is incomplete\n");
   } else if (device->info->gen >= 8) {
  /* Broadwell, Cherryview, Skylake, Broxton, Kabylake is as fully
   * supported as anything */
   } else {
  result = vk_errorf(VK_ERROR_INCOMPATIBLE_DRIVER,
 "Vulkan not yet supported on %s", device->name);
  goto fail;
   }

As far as earlier chipsets are concerned, Ironlake and earlier are
almost certainly never going to be supported. I don't know about Sandy
Bridge, but I doubt it. If you're unsure which Intel GPU you have:

% lspci -n -s 0:2
00:02.0 0300: 8086:0166 (rev 09)

and then match the device ID (here 0166) to the architecture code name
here:

Not necessarily. Until someone writes one, there are no plans to have one.

We have GL, I doubt we'll be writing compositors in Vulkan anytime soon,

fallbacks would probably be to use GL.

But eventually there will be Vulkan-only software and some fallback is 
needed for the hardware not supported by any hardware driver.

No, nothing concrete has been mentioned in this area at all.

sw rendering won't benefit from vulkan very much, in fact it would be worse
than GL in some cases, as Vulkan really works on the building up long 
command buffers and executing them, rather than direct execution in a context
that GL does.

What about software rendering? Is something like llvmpipe, or a port of the 
existing llvmpipe, in the works for Vulkan?

Looks good, but screen is not power off after 10 min, as configured.  I'm 
using KDE, so that could be an issue.

This is great, not only does the updated intel driver "enable" Vulkan, but it 
also seems to have fixed my tearing issue. I guess it what because DRI3 was

I had just installed vulkan on my Alienware m14x, and it seemed to erase my

No, AMD haven't shared any firm plans on Linux Vulkan support, I think the 
latest
is,

a binary stack will be released at some point supporting amdgpu using GPUs,
this binary stack at some undisclosed point after that will be open sourced.

DRI3 is a prerequisite, yes. The F23 builds of the intel driver had it
disabled until fairly recently, but this update should sort you out:

[ANNOUNCE] Fedora support for Vulkan

[Adam Jackson]

I'm pleased to announce support for Vulkan for Fedora!

== What is Vulkan? ==

Vulkan is a new generation graphics and compute API that provides high-
efficiency, cross-platform access to modern GPUs.

Or: Vulkan is to OpenGL as Wayland is to X11. It does many of the same
things, but - with the benefit of a few decades of experience - it's a
much better match for both the hardware it targets, and the
applications trying to use the hardware.

== How do I get it? ==

$ sudo dnf copr enable ajax/vulkan
$ sudo dnf install vulkan anvil vkcube
$ vulkaninfo

Currently the repository includes the driver loader, as well as Intel's
open source drivers for gen8+ (Broadwell, Cherryview, Skylake, Broxton
and Kabylake) GPUs. The Intel drivers also have incomplete support for
Ivybridge, Haswell, and Baytrail devices; I can vouch that the
Ivybridge support is good enough to run the vkcube demo.

Package reviews have been created so this can all be integrated into
the OS directly:

https://bugzilla.redhat.com/show_bug.cgi?id=1308985
https://bugzilla.redhat.com/show_bug.cgi?id=1308986

== What else can I do with it? ==

The Khronos group hosts a number of open source repositories related to
the Vulkan standard, including the specification and conformance test
suite:

https://github.com/KhronosGroup?utf8=%E2%9C%93=vulkan

A number of sample applications are available:

https://github.com/SaschaWillems/Vulkan
https://github.com/McNopper/Vulkan

The API reference is available online:

https://www.khronos.org/registry/vulkan/specs/1.0/refguide/Vulkan-1.0-web.pdf
https://www.khronos.org/registry/vulkan/specs/1.0/apispec.html

Your favorite hardware driver or 3D game engine quite likely could use
help in enabling a Vulkan port, if you feel like getting your hands
dirty. The vulkan branch of Mesa would be a good place to start:
