Mode setting is a software operation that activates a display mode (screen resolution, color depth, and refresh rate) for a computer's display controller by using VESA BIOS Extensions or UEFI Graphics extensions (on more modern computers).
In 2015, version 358.09 (beta) of the proprietary Nvidia GeForce driver received support for the DRM mode-setting interface implemented as a new kernel blob called nvidia-modeset.ko. This new driver component works in conjunction with the nvidia.ko kernel module to program the display engine (i.e. display controller) of the GPU. [197]
Their 2D X.Org driver is called xf86-video-intel. The kernel mode-setting driver in the Linux kernel does not use the video BIOS for switching video modes; since some BIOSes have a limited range of modes, this provides more reliable access to those supported by Intel video adapters.
Display Diagnostics, with Kernel mode device driver interface changes to allow the driver for a display controller to report diagnostic events to the operating system. Shared graphics power components , allowing non-graphics drivers to participate in the power management of a graphics device.
The Kernel-Mode Driver Framework (KMDF) is a driver framework developed by Microsoft as a tool to aid driver developers create and maintain kernel mode device drivers for Windows 2000 [a] and later releases. It is one of the frameworks included in the Windows Driver Frameworks. [1]
In the middle: the FOSS stack, composed out of DRM & KMS driver, libDRM and Mesa 3D.Right side: Proprietary drivers: Kernel BLOB and User-space components. nouveau (/ n uː ˈ v oʊ /) is a free and open-source graphics device driver for Nvidia video cards and the Tegra family of SoCs written by independent software engineers, with minor help from Nvidia employees.
The user will only see the blue screen if the system is not configured to automatically restart (which became the default setting in Windows XP SP2). Otherwise, it appears as though the system simply rebooted (though a blue screen may be visible briefly). In Windows, bug checks are only supported by the Windows NT kernel.
Graphics device drivers are implemented using two components: a UMD (user-mode driver) and a KMD (kernel-mode driver). Starting with Linux kernel 4.2 AMD Catalyst and Mesa will share the same Linux kernel driver: amdgpu. Amdgpu provides interfaces defined by DRM and KMS.
