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:

https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units

That got me close enough, mine is Ironlake.

Thanks,
Richard
