Vulkan format request: VK_FORMAT_S8_UINT #104

Description and steps to reproduce [Required]

The VK_FORMAT_S8_UINT format is currently not supported by any Intel Windows Vulkan driver. This is used in Nintendo Switch emulation, with emulators such as yuzu. I have implemented the use of this format in the following PR within yuzu, however, Intel does not have support for this format. At the moment, only NVIDIA has support for this format on their proprietary Windows drivers.

This format is available on OpenGL as GL_STENCIL_INDEX8. Is it possible to implement in Vulkan?

@EstebanIntel can you reconsider this issue?

Hi @Valkirie,

The problem with emulator issues, is that we have no legal way of reproducing the issues, as the games can't be legally acquired.

My advice actually get this resolved would be to have the developers of Yuzu to post their issue on our Developer Forum, where our support engineers specialized on the topic will pick it up.

Hi @EstebanIntel,

there is no need for games nor yuzu, the OP request is to implement a vulkan extension that is not available in windows intel vulkan driver, that, if i'm not wrong, is available in intel anv driver (mesa)

Hi @Morph1984, after consulting with our development team, due to their limited resources and needing to work on other higher priority game issues, VK_FORMAT_S8_UINT won't be supported on Arc A-Series GPUs.
