drm-dotnet

drm-dotnet are .NET bindings for libdrm, the userspace library for the Linux Direct Rendering Manager.

Usage

using Drm;

using var device = DrmDevice.Open("/dev/dri/card0");
Console.WriteLine($"Driver: {device.GetVersion()}");

var resources = device.GetResources();
var connector = resources.ConnectorIds
    .Select(id => device.GetConnector(id))
    .First(c => c.Status == DrmConnectionStatus.Connected && c.Modes.Count > 0);
var mode = connector.Modes.First(m => m.IsPreferred);

using var buffer = device.CreateDumbBuffer(mode.HorizontalDisplay, mode.VerticalDisplay);
buffer.AsSpan().Fill(0xFF); // draw something

using var framebuffer = device.AddFramebuffer(buffer);
device.SetCrtc(resources.CrtcIds[0], framebuffer.Id, 0, 0, [connector.ConnectorId], mode);

using Drm.Native;

unsafe
{
    var res = Libdrm.drmModeGetResources(fd);
    // ...
    Libdrm.drmModeFreeResources(res);
}

You can get a seat from seatd, which is bound with seatd-dotnet.

using var seatDevice = seat.OpenDevice("/dev/dri/card0");
using var drm = DrmDevice.FromFd(seatDevice.Fd, ownsFd: false);

Testing

sudo modprobe vkms
sudo chmod a+rw /dev/dri/card*   # or run as a user with access
dotnet test

Sample

samples/Drm.NET.Sample picks the first connected connector, draws a gradient into a dumb buffer, scans it out for a few seconds and restores the previous state. Run it from a VT (or against vkms), not from inside a desktop session:

dotnet run --project samples/Drm.NET.Sample -- /dev/dri/card0 5

Regenerating the bindings

git submodule update --init
dotnet tool restore
sh eng/generate.sh

Requires a system clang for its builtin-header resource directory.
