This has proven immensely useful for debugging memory leaks and overallocation (which is a rather serious concern on the platform, given that we typically run at about 256MB of CMA out of up to 1GB total memory, with framebuffers that are about 8MB ecah). The state of the art without this is to dump debug logs from every GL application, guess as to kernel allocations based on bo_stats, and try to merge that all together into a global picture of memory allocation state. With this, you can add a couple of calls to the debug build of the 3D driver and get a pretty detailed view of GPU memory usage from /debug/dri/0/bo_stats (or when we debug print to dmesg on allocation failure). The Mesa side currently labels at the gallium resource level (so you see that a 1920x20 pixmap has been created, presumably for the window system panel), but we could extend that to be even more useful with glObjectLabel() names being sent all the way down to the kernel. (partial) example of sorted debugfs output with Mesa labeling all resources: kernel BO cache: 16392kb BOs (3) tiling shadow 1920x1080: 8160kb BOs (1) resource 1920x1080@32/0: 8160kb BOs (1) scanout resource 1920x1080@32/0: 8100kb BOs (1) kernel: 8100kb BOs (1) v2: Use strndup_user(), use lockdep assertion instead of just a comment, fix an array[-1] reference, extend comment about name freeing.

In order to support CEC the hsm clock needs to be enabled in vc4_hdmi_bind(), not in vc4_hdmi_encoder_enable(). Otherwise you wouldn't be able to support CEC when there is no hotplug detect signal, which is required by some monitors that turn off the HPD when in standby, but keep the CEC bus alive so they can be woken up. The HDMI core also has to be enabled in vc4_hdmi_bind() for the same reason.

FB helper code falls back to a 1024x768 mode if no outputs are connected or don't report back any modes upon initialization. This can be annoying because outputs that are added to FB helper later on can't be used with FB helper if they don't support a matching mode. The fallback is in place because VGA connectors can happen to report an unknown connection status even when they are in fact connected. Some drivers have custom solutions in place to defer FB helper setup until at least one output is connected. But the logic behind these solutions is always the same and there is nothing driver-specific about it, so a better alterative is to fix the FB helper core and add support for all drivers automatically. This patch adds support for deferred FB helper setup. It checks all the connectors for their connection status, and if all of them report to be disconnected marks the FB helper as needing deferred setup. Whet setup is deferred, the FB helper core will automatically retry setup after a hotplug event, and it will keep trying until it succeeds. v2: Rebase onto my entirely reworked fbdev helper locking. One big difference is that this version again drops&reacquires the fbdev lock (which is now fb_helper->lock, but before this patch series it was mode_config->mutex), because register_framebuffer must be able to recurse back into fbdev helper code for the initial screen setup. v3: __drm_fb_helper_initial_config must hold fb_helper->lock upon return, I've fumbled that in the deferred setup case (Liviu). v4: I was blind, redo this all. __drm_fb_helper_initial_config shouldn't need to reacquire fb_helper->lock, that just confuses callers. I myself got confused by kernel_fb_helper_lock and somehow thought it's the same as fb_helper->lock. Tsk. Also simplify the logic a bit (we don't need two functions to probe connectors), we can stick much closer to the existing code.

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.
