I didn't bother with documenting the really trivial new "extract something from dpcd" helpers, but the i2c over aux ch is now documented a bit. v2: Clarify the comment for i2c_dp_aux_add_bus a bit. v3: Fix more spelling fail spotted by Laurent Pinchart.

- Add the missing doc for drm_helper_move_panel_connectors_to_head. - Fixup any outdated stuff in existing sections. I've only looked at those kerneldoc headers that actually resulted in a complaint from the kerneldoc parser tool. v2: - Actually include the docbook snippet in the right patch. - Fix spelling fail. v3: It's now called drm_crtc_helper_set_mode, spotted by Laurent Pinchart.

Prevent ati_pcigart.c being built unless PCI is enabled. The exported functions in this file are only used by drivers which depend on PCI (namely r128 and radeon), and it tries to use PCI specific functions (pci_unmap_page, pci_map_page, and pci_dma_mapping_error) that cause compiler errors when PCI is disabled.

Reservation locking currently always takes place under the LRU spinlock. Hence, strictly there is no need for an atomic_cmpxchg call; we can use atomic_read followed by atomic_write since nobody else will ever reserve without the lru spinlock held. At least on Intel this should remove a locked bus cycle on successful reserve. Note that thit commit may be obsoleted by the cross-device reservation work.

The mostly used lookup+get put+potential_destroy path of TTM objects is converted to use RCU locks. This will substantially decrease the amount of locked bus cycles during normal operation. Since we use kfree_rcu to free the objects, no rcu synchronization is needed at module unload time. v2: Don't touch include/linux/kref.h v3: Adapt to kref_get_unless_zero return value change Signed-off-by: NThomas Hellstrom <thellstrom@vmware.com> Signed-off-by: NDave Airlie <airlied@redhat.com>

This function is intended to simplify locking around refcounting for objects that can be looked up from a lookup structure, and which are removed from that lookup structure in the object destructor. Operations on such objects require at least a read lock around lookup + kref_get, and a write lock around kref_put + remove from lookup structure. Furthermore, RCU implementations become extremely tricky. With a lookup followed by a kref_get_unless_zero *with return value check* locking in the kref_put path can be deferred to the actual removal from the lookup structure and RCU lookups become trivial. v2: Formatting fixes. v3: Invert the return value.

When trying to obtain an accurate timestamp for the last vsync interrupt in vblank_disable_and_save() we loop until the vsync counter after reading the time stamp is identical to the one before. In the case where no hardware timestamp can be obtained there is probably no point in trying to make sure we remain within the same vsync during the time we obtain the counter. Furthermore we should make sure there's an 'emergency exit' so that we don't end up in an endless loop when the driver get_vblank_timestamp() function doesn't manage to return within the same vsync. This may happen when this function prints out debugging information over a slow (ie serial) line. Signed-off-by: NEgbert Eich <eich@suse.de> Signed-off-by: NDave Airlie <airlied@redhat.com>

... by properly checking connector->polled. This doesn't matter too much because the polling work itself gets this slightly more right and doesn't set repoll if there's nothing to do. But we can do better. v2: Chris Wilson noticed that I broke polling, since repoll will never ever be set true. Fix this up, and simplify the logic a bit while at it.
