The only 32-bit image format supported by X11 is B8G8R8A8_UNORM which is not one of the standard storage image formats. I think Wayland is basically the same. Since anv requires a format to be specified in the shader for storage image reads, it's a bit tricky to support B8G8R8A8_UNORM because there is no SPIR-V enum for it. I've actually been looking into how to best support it for the last couple of weeks and have a few ideas but nothing solid yet.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
