Development[edit]

AMDgpu is AMD's fully open source unified kernel driver for its GPUs on Linux. It takes the form of an in-tree kernel module.

As of 2022, AMD Kernel Fusion Driver (KFD) is now integrated in this one kernel module. AMD KFD development at AMD is part of ROCm, under the ROCk project.

Distribution[edit]

AMDgpu has been fully upstreamed and new developments continue to do so.

As AMDgpu is part of the monolithic Linux kernel, it is shipped by most Linux distributions directly. The package suite / install script amdgpu-pro, distributed by AMD directly from AMD Radeon Software, ships an AMDgpu kernel module somewhat reliably more up-to-date compared to that of kernels shipped in regular operating system distributions.

Community[edit]

The development of the kernel module happens between AMD and the Linux maintainers, discussions happen on the freedesktop.org mailing lists[3][4] - freedesktop being home to major Linux graphics projects such as Mesa, libdrm, Xorg, Wayland.

Support[edit]

AMDgpu officially supports cards built upon GCN 1.2 or higher, including new instruction sets such as RDNA1&2, CDNA.

Support issues[edit]

Though as of 2022 support for GCN 1.0/1.1 is incomplete,[5] it can be enabled by a kernel parameter[6][7] and some Linux distributions enabled it by default.[8]
