Struct wlroots::backend::Drm

pub struct Drm { /* fields omitted */ }

When the compositor is ran on a TTY and has full control of the system resources.

This is primarily the backend that end users will use, as they usually want the compositor to run standalone.

Note that because you have full control of the TTY (and the keyboard, the mouse, and just about everything else) that if there's an infinite loop then you could hard-lock yourself out of the system. At that point you must reboot your computer (or use SysRq).

Note that if the process exits for any reason (a panic, an abort, or a clean exit) all of the resource handles will automatically be cleaned up properly by the OS.

Methods

impl Drm

pub unsafe fn new(     display: *mut wl_display,     session: Session,     gpu_fd: c_int,     parent: Option<Drm>,     render_setup_func: Option<UnsafeRenderSetupFunction> ) -> Self

Creates a DRM backend using the specified GPU file descriptor (typically from a device node in /dev/dri).

To slave this to another DRM backend, pass it as the parent (which must be a DRM backend, other kinds of backends raise SIGABRT).

pub fn output_is_drm(&self, output: &Output) -> bool

pub unsafe fn as_ptr(&self) -> *mut wlr_backend
