I am trying to support an emulator which has a half-done emulation of the PL111 registers. The other panels actually attached to real world instances of PL111 made in silicon, all have proper drivers in drivers/gpu/drm/panel already. All real electronics are already covered. They use: drivers/gpu/drm/panel/panel-arm-versatile.c drivers/gpu/drm/bridge/dumb-vga-dac.c All QEMU emulators are already covered (by making QEMU emulation behave like real hardware). It now uses DDC by way of dumb-vga-dac.c. This virtual display in this emulator is the missing final piece to convert the PL111 fbdev driver over to use DRM.
