A new option has been added to Vkrunner (the Vulkan shader testing tool written by Neil Roberts) to allow selecting the Vulkan device for each shader test.
Usage:
|
1 |
vkrunner --device-id <number> [OPTION]... SCRIPT |
or
|
1 |
vkrunner --device-id=<number> [OPTION]... SCRIPT |
When the device id is not set, the default GPU is used. IDs start from 1 to match the convention of the VK-GL-CTS conformance tests by Khronos.
Also, Vkrunner now supports long options. You can use the options --help or -h to see them.
