Mostly nothing special (except making sure that really all error paths and friends call iter_put). v2: Don't forget the raw connector_list walking in drm_helper_move_panel_connectors_to_head. That one unfortunately can't be converted to the iterator helpers, but since it's just some list splicing best to just wrap the entire thing up in one critical section. v3: Bail out after iter_put (Harry).

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.

Rather than compare the format u32s of two format infos, we can direclty compare the format info pointers themselves. Noramlly all the ->format pointers all point to somwehere in the big array, so this is a valid way to test for equality. Also drivers may want to point ->format at a private format info struct instead (eg. for special compressed formats with extra planes), so just comparing the pixel format values wouldn't necessaritly even work.

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8. Less duplicated information is a good thing. Note that I didn't put parens around the cpp*8 in the below cocci script, on account of not wanting spurious parens all over the place. Instead I did the unsafe way, and tried to look over the entire diff to spot if any dangerous expressions were produced. I didn't see any. There are some cases where previously the code did X*bpp/8, so the division happened after the multiplication. Those are now just X*cpp so the division effectively happens before the multiplication, but that is perfectly fine since bpp is always a multiple of 8. @@ struct drm_framebuffer *FB; expression E; @@ drm_helper_mode_fill_fb_struct(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ i9xx_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ ironlake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ skylake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer FB; expression E; @@ ( - E * FB.bits_per_pixel / 8 + E * FB.format->cpp[0] | - FB.bits_per_pixel / 8 + FB.format->cpp[0] | - E * FB.bits_per_pixel >> 3 + E * FB.format->cpp[0] | - FB.bits_per_pixel >> 3 + FB.format->cpp[0] | - (FB.bits_per_pixel + 7) / 8 + FB.format->cpp[0] | - FB.bits_per_pixel + FB.format->cpp[0] * 8 | - FB.format->cpp[0] * 8 != 8 + FB.format->cpp[0] != 1 ) @@ struct drm_framebuffer *FB; expression E; @@ ( - E * FB->bits_per_pixel / 8 + E * FB->format->cpp[0] | - FB->bits_per_pixel / 8 + FB->format->cpp[0] | - E * FB->bits_per_pixel >> 3 + E * FB->format->cpp[0] | - FB->bits_per_pixel >> 3 + FB->format->cpp[0] | - (FB->bits_per_pixel + 7) / 8 + FB->format->cpp[0] | - FB->bits_per_pixel + FB->format->cpp[0] * 8 | - FB->format->cpp[0] * 8 != 8 + FB->format->cpp[0] != 1 ) @@ struct drm_plane_state *state; expression E; @@ ( - E * state->fb->bits_per_pixel / 8 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel / 8 + state->fb->format->cpp[0] | - E * state->fb->bits_per_pixel >> 3 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel >> 3 + state->fb->format->cpp[0] | - (state->fb->bits_per_pixel + 7) / 8 + state->fb->format->cpp[0] | - state->fb->bits_per_pixel + state->fb->format->cpp[0] * 8 | - state->fb->format->cpp[0] * 8 != 8 + state->fb->format->cpp[0] != 1 ) @@ @@ - (8 * 8) + 8 * 8 @@ struct drm_framebuffer FB; @@ - (FB.format->cpp[0]) + FB.format->cpp[0] @@ struct drm_framebuffer *FB; @@ - (FB->format->cpp[0]) + FB->format->cpp[0] @@ @@ struct drm_framebuffer { ... - int bits_per_pixel; ... }; v2: Clean up the 'cpp*8 != 8' and '(8 * 8)' cases (Laurent) v3: Adjusted the semantic patch a bit and regenerated due to code changes Signed-off-by: -
