            Bug ID: 49813
           Summary: Implement debugging feedback extensions
                    (VK_EXT_debug_utils/VK_EXT_debug_report) to forward
                    data to Linux impl
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: winevulkan
          Assignee: wine-bugs at winehq.org
          Reporter: loothelion at nvidia.com
      Distribution: ---

Was discussing the following earlier with Georg Lehmann and Hans-Kristian
Arntzen:

Looking for a way to forward application Vulkan API debugging info (tagged
objects / perfmarkers / queue-labels) such that the host loader will receive
these calls from the windows application.

I believe that VK_EXT_debug_marker should pass-through fine with ToT
winevulkan, but that should be confirmed.

A few thoughts on test cases to verify this missing functionality / verify an
implementation:

- Sascha Willems' debugmarker example -
https://github.com/SaschaWillems/Vulkan/tree/master/examples/debugmarker (uses
VK_EXT_debug_marker)

- Quake 2 RTX - https://github.com/NVIDIA/Q2RTX (uses
VK_EXT_debug_utils/VK_EXT_debug_report)

- Should add to dlls/vulkan-1/tests for a simple usage of tagging an object
(similar to the private data test). Maybe a small companion layer that just
plainly prints out debug information would also be of use.

Connecting to these applications via a graphics debugging tool should yield
Vulkan debug information from the application.


Some potential challenges that may be hit:

- Implementation of debug utils messenger callback in concern with
calling-convention and alignment

- make_vulkan currently notes interaction issues with VK_EXT_debug_marker and
VK_EXT_debug_utils and implementations within LunarG's vulkan-1.dll, we may
wish to conditionally expose this functionality either via a regkey, or if we
detect WINE's vulkan-1.dll implementation is in use.
