As a userspace developer, creating graphical applications is a common task. While software and frameworks like Weston or Qt make it straightforward to display content on a screen, ensuring compatibility across various displays poses significant challenges. Users may have different screen sizes, resolutions, and capabilities, making comprehensive testing complex. How will your application perform on a small screen? What about an extremely large one? How does it react to displays being connected/disconnected? Moreover, if your application must run on diverse devices, how will it leverage or adapt to varying hardware capabilities?
VKMS addresses these challenges by enabling graphic testing without the need for physical hardware. VKMS is a Linux kernel DRM driver that allows you to emulate a wide range of display configurations on any device. This talk will introduce VKMS, highlight its current capabilities, demonstrate practical test examples, and provide details on additional features we are currently working on upstreaming into VKMS.
