Dear Mesa developers,
I'm looking into further improving adriconf[1] as a tool to configure mesa
driver options.
Vulkan mesa drivers can now read their configuration options from the .drirc
configuration file.
With this in mind I have the following question to mesa developers:
- Are Vulkan drivers using the same options as their OpenGL drivers?
eg: Does Intel ANV uses the same options as i965?
You can check the options used by anv at the top of
src/intel/vulkan/anv_device.c
Almost nothing in common with i965.
- In case the options are different (which is quite likely), how do we query
the available options?
For OpenGL we have glXGetScreenDriver/glXGetDriverConfig
For EGL we have eglGetDisplayDriverName/eglGetDisplayDriverConfig [2]
What about Vulkan? How can we query such options?
I guess you'll have to add an extension to provide the same feature.

Kind regards,
