Add forward declaration and pull in include file to make drm_framebuffer.h self contained. While add it order include files alphabetically. The use of TASK_COMM_LEN is the reason for including sched.h. I could not see any good way to avoid this dependency, and users of drm_framebuffer.comm already use TASK_COMM_LEN to check for length etc. v2: - Added forward declaration of drm_gem_object (Noralf) - Added ack from Noralf Signed-off-by:

Move DRM_SWITCH_POWER out of drmP.h to allow users to get rid of the drmP include. Moved to drm_device.h because drm_device.switch_power_state is the only user. Converted to enum and added sparse kerneldoc comments. Signed-off-by:

Updated comment style to kernel-doc format in drm_device.h In struct drm_device there are 12 struct members without doc: - registered - filelist_mutex - filelist - irq - vbl_lock - event_lock - hose - sigdata - sigdata.context - sigdata.lock - agp_buffer_map - agp_buffer_token They all need proper documentation, a task left for someone that knows their usage. drm_device is not plugged into Documentation/gpu/drm-internals.rst as this would create a new load of warnings.

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

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.
