Details

Mesa 22.3 split off [1] vulkan support for older Intel GPUs like Ivy Bridge into an additional driver called intel hasvk [2]. Please add support for it too.

It is as simple as adding "intel_hasvk" [2] to the '-D vulkan-drivers=' array line in the PKGBUILD, patch attached.

Short explanation:
The vulkan intel_hasvk driver was split off from ANV so that upstream (mostly Intel) could focus on newer features and they dropped support for older generations of intel GPUs before the final 22.3 release happened within ANV. In order to use vulkan on Ivy Bridge for instance, intel_hasvk has to be enabled in mesa.

[2]: https://gitlab.freedesktop.org/mesa/mesa/-/blob/22.3/meson_options.txt#L188


Additional info:
* mesa-22.3.0
* Get Vulkan support with older Intel GPUs

Steps to reproduce:
Use vulkaninfo, which displays an ERROR message: failed to detect any valid GPUs in the current config
Try to use vulkan, not working until explicitly enabled with intel_hasvk for older Intel GPUs, but still supported with mesa-22.3.

Also a few minor tweaks are necessary in the package_vulkan-intel() function, so that the new libvulkan_intel_hasvk.so and intel_hasvk_icd.x86_64.json file gets packaged in the right places.

_install fakeinstall/usr/share/vulkan/icd.d/intel_hasvk_icd.x86_64.json
_install fakeinstall/usr/lib/libvulkan_intel_hasvk.so
