There's more stuff that can be shared in the constructor, will be merged together again later. Signed-off-by: -

This is in preparation for extending the support to the remaining chipsets, to allow for sharing more functions. Signed-off-by: -

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. Acked-by:

Again only minimal changes to make kerneldoc no longer shout. Plus a little introduction in the form of a inline DOC: section to quickly explain what this is all about. v2: Fixup spelling fail. Acked-by:

- 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 - Fixup any outdated stuff in existing sections.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.

Those tend to be totally not interesting for end-users, and for debugging we tend to dump the entire noise anyway by enabling all debug messages. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=57388Signed-off-by:

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.

Instead of using the stride derived from the display mode, use the pitch associated with the currently active framebuffer. This fixes a bug where the LCD display content would be skewed when enabling HDMI with a video mode different from that of the LCD. Signed-off-by:

While hashtab should now be RCU-safe, Add a drm_ht_xxx_api for consumers to use to make it obvious what locking mechanism is used. Document the way the rcu-safe interface should be used. Don't use rcu-safe list traversal in modify operations where we should use a spinlock / mutex anyway. Signed-off-by:

Refactor resource management to make it easy to hook up resources that are backed up by buffers. In particular, resources and their backing buffers can be evicted and rebound, if supported by the device. To avoid query deadlocks, the query code is also modified somewhat. Signed-off-by:

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. Signed-off-by:

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:

Thomas Hellstrom authored
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.
