Subject: [PATCH 0/5] drm/sysfb: Support basic power management
Date: Wed, 8 Apr 2026 14:03:13 +0200 [thread overview]
Message-ID: <20260408120722.328769-1-tzimmermann@suse.de> (raw)
Add callbacks for suspending and resuming to the sysfb drivers. The
helpers store and restore DRM state across the suspend/resume cycle.
While most hardware loses the system framebuffer setup on suspends,
some systems do retain the configuration; notable emulators. Adding
PM support makes it work with DRM.
Tested with vesadrm on qemu's bochs device.
