Fairly commonly we want to inspect the node list on the struct drm_mm, which is buried within an embedded node. Bring it to the surface with a bit of syntatic sugar. Note this was intended to be split from commit ad579002 ("drm: Add drm_mm_for_each_node_safe()") before being applied, but my timing sucks.

The requirements for connector_list locking are a bit tricky: - We need to be able to jump over zombie conectors (i.e. with refcount == 0, but not yet removed from the list). If instead we require that there's no zombies on the list then the final kref_put must happen under the list protection lock, which means that locking context leaks all over the place. Not pretty - better to deal with zombies and wrap the locking just around the list_del in the destructor. - When we walk the list we must _not_ hold the connector list lock. We walk the connector list at an absolutely massive amounts of places, if all those places can't ever call drm_connector_unreference the code would get unecessarily complicated. - connector_list needs it own lock, again too many places that walk it that we could reuse e.g. mode_config.mutex without resulting in inversions. - Lots of code uses these loops to look-up a connector, i.e. they want to be able to call drm_connector_reference. But on the other hand we want connectors to stay on that list until they're dead (i.e. connector_list can't hold a full reference), which means despite the "can't hold lock for the loop body" rule we need to make sure a connector doesn't suddenly become a zombie. At first Dave&I discussed various horror-show approaches using srcu, but turns out it's fairly easy: - For the loop body we always hold an additional reference to the current connector. That means it can't zombify, and it also means it'll stay on the list, which means we can use it as our iterator to find the next connector. - When we try to find the next connector we only have to jump over zombies. To make sure we don't chase bad pointers that entire loop is protected with the new connect_list_lock spinlock. And because we know that we're starting out with a non-zombie (need to drop our reference for the old connector only after we have our new one), we're guranteed to still be on the connector_list and either find the next non-zombie or complete the iteration. - Only downside is that we need to make sure that the temporary reference for the loop body doesn't leak. iter_get/put() functions + lockdep make sure that's the case. - To avoid a flag day the new iterator macro has an _iter postfix. We can rename it back once all the users of the unsafe version are gone (there's about 100 list walkers for the connector_list). For now this patch only converts all the list walking in the core, leaving helpers and drivers for later patches. The nice thing is that we can now finally remove 2 FIXME comments from the register/unregister functions. v2: - use irqsafe spinlocks, so that we can use this in drm_state_dump too. - nuke drm_modeset_lock_all from drm_connector_init, now entirely cargo-culted nonsense. v3: - do {} while (!kref_get_unless_zero), makes for a tidier loop (Dave). - pretty kerneldoc - add EXPORT_SYMBOL, helpers&drivers are supposed to use this. v4: Change lockdep annotations to only check whether we release the iter fake lock again (i.e. make sure that iter_put is called), but not check any locking dependecies itself. That seams to require a recursive read lock in trylock mode.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

On most platforms, there exists this ifdef: #define atomic_inc_not_zero(v) atomic_add_unless((v), 1, 0) This makes this patch functionally useless. However, on PPC, there is actually an explicit definition of atomic_inc_not_zero with its own assembly that is slightly more optimized than atomic_add_unless. So, this patch changes kref to use atomic_inc_not_zero instead, for PPC and any future platforms that might provide an explicit implementation. This also puts this usage of kref more in line with a verbatim reading of the examples in Paul McKenney's paper [1] in the section titled "2.4 Atomic Counting With Check and Release Memory Barrier", which uses atomic_inc_not_zero.

No one looks at the major/minor versions except the unique/busid stuff. If we protect that with the master_mutex (since it also affects the unique of each master, oh well) we can mark these two IOCTL with DRM_UNLOCKED. While doing this I realized that the comment for the magic_map is outdated, I've forgotten to update it in: commit d2b34ee6 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jun 17 09:33:21 2016 +0200 drm: Protect authmagic with master_mutex Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: NChris Wilson <chris@chris-wilson.co.uk> Reviewed-by: NEmil Velikov <emil.l.velikov@gmail.com> Signed-off-by: NDaniel Vetter <daniel.vetter@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20161210215255.7765-1-daniel.vetter@ffwll.ch

Not setting the fb modifiers flag is something different from setting the fb modifiers to 0 (which means explicitly linear). We kinda failed to document that properly. Spotted by Kristian.

Some generic TV connector properties are exposed in drm_mode_config, but they are currently handled independently in each DRM encoder driver. Extend the drm_connector_state to store TV related states, and modify the drm_atomic_connector_{set,get}_property() helpers to fill the connector state accordingly. Each driver is then responsible for checking and applying the new config in its ->atomic_mode_{check,set}() operations.

With binutils-2.26 and before, a weak missing symbol was kept during the final link, and a missing CRC for an export would lead to that CRC being treated as zero implicitly. With binutils-2.27, the crc symbol gets dropped, and any module trying to use it will fail to load. This sets the weak CRC symbol to zero explicitly, making it defined in vmlinux, which in turn lets us load the modules referring to that CRC. The comment above the __CRC_SYMBOL macro suggests that this was always the intention, although it also seems that all symbols defined in C have a correct CRC these days, and only the exports that are now done in assembly need this.

Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.

Hugetlb pages have ->index in size of the huge pages (PMD_SIZE or PUD_SIZE), not in PAGE_SIZE as other types of pages. This means we cannot user page_to_pgoff() to check whether we've got the right page for the radix-tree index. Let's introduce page_to_index() which would return radix-tree index for given page. We will be able to get rid of this once hugetlb will be switched to multi-order entries.
