After drm_fb_helper_fbdev_setup calls drm_fb_helper_init, "dev->fb_helper" will be initialized (and thus drm_fb_helper_fini will have some effect). After that, drm_fb_helper_initial_config is called which may call the "fb_probe" driver callback. This driver callback may call drm_fb_helper_defio_init (as is done by drm_fb_helper_generic_probe) or set a framebuffer (as is done by bochs) as documented. These are normally cleaned up on exit by drm_fb_helper_fbdev_teardown which also calls drm_fb_helper_fini. If an error occurs after "fb_probe", but before setup is complete, then calling just drm_fb_helper_fini will leak resources. This was triggered by df2052cc ("bochs: convert to drm_fb_helper_fbdev_setup/teardown"): [ 50.008030] bochsdrmfb: enable CONFIG_FB_LITTLE_ENDIAN to support this framebuffer [ 50.009436] bochs-drm 0000:00:02.0: [drm:drm_fb_helper_fbdev_setup] *ERROR* fbdev: Failed to set configuration (ret=-38) [ 50.011456] [drm] Initialized bochs-drm 1.0.0 20130925 for 0000:00:02.0 on minor 2 [ 50.013604] WARNING: CPU: 1 PID: 1 at drivers/gpu/drm/drm_mode_config.c:477 drm_mode_config_cleanup+0x280/0x2a0 [ 50.016175] CPU: 1 PID: 1 Comm: swapper/0 Tainted: G T 4.20.0-rc7 #1 [ 50.017732] EIP: drm_mode_config_cleanup+0x280/0x2a0 ...

If register_framebuffer() fails during fbdev setup we will leak the framebuffer, the GEM buffer and the shadow buffer for defio. This is because drm_fb_helper_fbdev_setup() just calls drm_fb_helper_fini() on error not taking into account that register_framebuffer() can fail. Since the generic emulation uses DRM client for its framebuffer and backing buffer in addition to a shadow buffer, it's necessary to open code drm_fb_helper_fbdev_setup() to properly handle the error path. Error cleanup is removed from .fb_probe and is handled by one function for all paths. Fixes: 9060d7f4 ("drm/fb-helper: Finish the generic fbdev emulation") Reported-by:

Now that the plane code takes the margins setup into account, we can safely attach margin props to the HDMI connector. We also take care of filling AVI infoframes correctly to expose the top/botton/left/right bar. Note that those margin props match pretty well the overscan_{left,right,top,bottom} properties defined in config.txt and parsed by the VC4 firmware.
