In June 2014, Codethink reportedly ran a Wayland-based Weston compositor with Linux kernel 3.15, using EGL and a "100% open-source graphics driver stack" on a Tegra K1. [46] A feature matrix is available. [47] In July 2014, Nouveau was unable to outperform the Nvidia GeForce driver due to missing re-clocking support.
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 most prominent alternative driver is the reverse-engineered free and open-source nouveau graphics device driver. Nvidia has publicly announced to not provide any support for such additional device drivers for their products, [60] although Nvidia has contributed code to the Nouveau driver. [61]
If a WDDM driver hangs or encounters a fault, the graphics stack will restart the driver. [2] [9] A graphics hardware fault will be intercepted and if necessary the driver will be reset. Drivers under Windows XP were free to deal with hardware faults as they saw fit either by reporting it to the user or by attempting to recover silently.
[33] [34] The issue was initially attributed to Nvidia GeForce graphics drivers; however, in a driver update published on April 13, 2024, Nvidia acknowledged the instability problem as being associated with the Intel 13th/14th generation CPUs, and that owners of them should contact Intel customer support for further assistance. [35]
As of Windows Vista Beta 2, the NVIDIA GeForce 6 series and later, the ATI Radeon 9500 and later, Intel's GMA 950 and later integrated graphics, and a handful of VIA chipsets and S3 Graphics discrete chips are supported. Although originally supported, the GeForce FX 5 series has been dropped from newer drivers from NVIDIA.
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. [9] A display server using the Wayland protocol is called a Wayland compositor, because it additionally performs the task of a compositing window manager.
Raspberry Pi can use a VideoCore IV GPU via a binary blob, which is loaded into the GPU at boot time from the SD-card, and additional software, that initially was closed source. [225] This part of the driver code was later released. [226] However, much of the actual driver work is done using the closed source GPU code.
