But disabled by default. This essentially reverts commit bcd5023c Author: Dave Airlie <airlied@redhat.com> Date: Mon Mar 14 14:17:55 2011 +1000 drm/i915: disable opregion lid detection for now but leaves the autodetect mode disabled. There's also the explicit lid status option added in commit fca87409 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Feb 17 13:44:48 2011 +0000 drm/i915: Add a module parameter to ignore lid status Which overloaded the meaning for the panel_ignore_lid parameter even more. To fix up this mess, give the non-negative numbers 0,1 the original meaning back and use negative numbers to force a given state. So now we have 1 - disable autodetect, return unknown 0 - enable autodetect -1 - force to disconnected/lid closed -2 - force to connected/lid open v2: My C programmer license has been revoked ... v3: Beautify the code a bit, as suggested by Chris Wilson.

In order to prevent reaping of the object whilst setting it up to handle the pagefault, we need to mark it as pinned. This has the nice side-effect of eliminating some special cases from the pagefault handler as well! Signed-off-by:

In the circumstances that the shrinker is allowed to steal the mutex in order to reap pages, we need to be careful to prevent it operating on the current object and shooting ourselves in the foot. Signed-off-by:

The intention of checking obj->gtt_offset!=0 is to verify that the target object was listed in the execbuffer and had been bound into the GTT. This is guarranteed by the earlier rearrangement to split the execbuffer operation into reserve and relocation phases and then verified by the check that the target handle had been processed during the reservation phase. However, the actual checking of obj->gtt_offset==0 is bogus as we can indeed reference an object at offset 0. For instance, the framebuffer installed by the BIOS often resides at offset 0 - causing EINVAL as we legimately try to render using the stolen fb. Signed-off-by:

Now that we always restore the HWS registers (both physical and GTT virtual addresses) when re-initialising the rings, we can eliminate the superfluous save/restore of the register across suspend and resume. Signed-off-by:

Jani Nikula noticed that the parentheses are wrong and we & the bit with the register address instead of the read-back value. He sent a patch to correct that. On second look, we write the same register in the previous line, and the w/a seems to be to set FDI_RX_PHASE_SYNC_POINTER_OVR to enable the logic, then keep always set FDI_RX_PHASE_SYNC_POINTER_OVR and toggle FDI_RX_PHASE_SYNC_POINTER_EN before/after enabling the pc transcoder. So the right things seems to be to simply kill the 2nd write. Cc: Jani Nikula <jani.nikula@intel.com> Reviewed-by:

The bspec was recently updated to remove the ability to update the semaphore using the MI_SEMAPHORE_BOX command, the ability to wait upon the semaphore value remained. Instead the advice is to update the register using the MI_LOAD_REGISTER_IMM command. In cursory testing, semaphores continue to function - the question is whether this fixes some of the deadlocks where the semaphore registers contained stale values? 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:

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:

... 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. Signed-off-by:
