Description mrc_munir 2017-01-22 12:38:59 UTC 
Tested with RPCS3 app 

From branch implemented Vulkan for linux

https://github.com/rcaridade145/rpcs3

Returned St13runtime_error thrown: No hardware support for z24s8

Acording the rpcs3/Emu/RSX/VK/VKFormats.cpp

	case rsx::surface_depth_format::z16: return VK_FORMAT_D16_UNORM;
	case rsx::surface_depth_format::z24s8:
	{
		if (support.d24_unorm_s8) return VK_FORMAT_D24_UNORM_S8_UINT;
		if (support.d32_sfloat_s8) return VK_FORMAT_D32_SFLOAT_S8_UINT;
		fmt::throw_exception("No hardware support for z24s8" HERE)


Tested on HW Ivy bridge Vulkan driver with Mesa 17.1.0-devel (git-494b63f525)

Update actually  has in the master mainline code

The drivers not changes to much on this

FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT or FORMAT_FEATURE_SAMPLED_IMAGE_BIT not supported in VK_FORMAT_D24_UNORM_S8_UINT or VK_FORMAT_D32_UNORM_S8_UINT extensions?

Vulkaninfo only returned 

	optimalTiling  FormatFeatureFlags:
		VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT
		VK_FORMAT_FEATURE_BLIT_SRC_BIT
		VK_FORMAT_FEATURE_BLIT_DST_BIT

Yes, stencil texturing is still not supported on gen7.  I've recently done some work which adds some of the infrastructure we need in order to do this but it's still quite a bit of work.

I'm having the same problem using Haswell with Mesa 17.3.0-2 in Archlinux

Mesa 19.2 (Git) in Archlinux same with Gen7 (Intel HD4000)
