LunarG updated the vulkaninfo program to improve the user experience. This program is located in the Vulkan SDK available on the LunarXchange website. Two changes were made to vulkaninfo — the addition of the 1) -html and 2) -j and -json options.

Overview of Vulkan Info improvements

Developers can use the vulkaninfo program to help characterize a system by outputting a variety of pertinent Vulkan information to standard output. To improve the user experience, the added -html option redirects this output and organizes the same information in a convenient, more visually appealing HTML format. The user can then open the vulkaninfo.html file in a favorite browser to view their system’s information. The collapsibility of the sections gives the user more control over which piece of hardware and/or type of Vulkan information receives the most visibility at the time of viewing.

LunarG also added the -j and -json options. These additions introduce the ability to organize vulkaninfo output into a DevSim-schema-compatible JSON file. DevSim refers to the LunarG Device Simulation tool that is also found on the LunarXchange.com website. This option takes the original vulkaninfo output and organizes the information in a different format — JSON. The JSON text isn’t necessarily easier to read but can be used with other tools in the Vulkan toolbox, specifically the VK_LAYER_LUNARG_device_simulation layer.
