Because intel_dp_init_connector is too big for my poor little brain. No functional changes. Signed-off-by:

By the time we call intel_dp_destroy (which destroys the connector) the encoder may have been destroyed already, so if we use it we may be reading some free memory. That happens in drm_mode_config_cleanup() and also inside intel_dp_init_connector() when we detect a ghost eDP. I also hope this may solve some random memory bugs. Reported by kmemcheck.

This reverts commit 160954b7. This was rearming the workqueue with a 0 timeout, causing a WARN_ON, and possible loop. Daniel writes: "I've looked a bit into this and I think we need to have a separate work struct for recovering these lost hotplug events since the continuous self-rearming case is a real risk (e.g. if a connector flip-flops all the time). At least I don't see a sane way to block out re-arming with the current code in a simple way. So reverting the offender seems like the right thing and I'll go back to the drawing board for 3.12."

The drm_gem_mmap_obj() has to be protected with dev->struct_mutex, but some caller functions do not. So it adds mutex lock to missing callers and adds assertion to check whether drm_gem_mmap_obj() is called with mutex lock or not. Signed-off-by:

Now that the code is compatible in semantics, flip the switch. Use ww_mutex instead of the homegrown implementation. ww_mutex uses -EDEADLK to signal that the caller has to back off, and -EALREADY to indicate this buffer is already held by the caller. ttm used -EAGAIN and -EDEADLK for those, respectively. So some changes were needed to handle this correctly. Signed-off-by:

This commit converts the source of the val_seq counter to the ww_mutex api. The reservation objects are converted later, because there is still a lockdep splat in nouveau that has to resolved first. Signed-off-by:

Maarten Lankhorst authored
This adds support for a generic reservations framework that can be hooked up to ttm and dma-buf and allows easy sharing of reservations across devices. The idea is that a dma-buf and ttm object both will get a pointer to a struct reservation_object, which has to be reserved before anything is done with the contents of the dma-buf. Changes since v1: - Fix locking issue in ticket_reserve, which could cause mutex_unlock to be called too many times. Changes since v2: - All fence related calls and members have been taken out for now, what's left is the bare minimum to be useful for ttm locking conversion. Changes since v3: - Removed helper functions too. The documentation has an example implementation for locking. With the move to ww_mutex there is no need to have much logic any more. Signed-off-by:

Merge tag 'drm-intel-next-2013-06-18' of git://people.freedesktop.org/~danvet/drm-intel into drm-next Last 3.11 feature pull. I have a few odds bits and pieces and fixes in my queue, I'll sort them out later on to see what's for 3.11-fixes and what's for 3.12. But nothing to hold this here up imo. Highlights: - more hangcheck work from Mika and Chris to prepare for arb robustness - trickle feed fixes from Ville - first parts of the shared pch pll rework, with some basic hw state readout and cross-checking (this shuts up the confused pch pll refcount WARN that Linus just recently forwarded) - Haswell audio power well support from Wang Xingchao (alsa bits acked by Takashi) - some cleanups and asserts sprinkling around the plane/gamma enabling sequence from Ville - more gtt refactoring from Ben - clear up the adjusted->mode vs. pixel clock vs. port clock confusion - 30bpp support, this time for real hopefully * tag 'drm-intel-next-2013-06-18' of git://people.freedesktop.org/~danvet/drm-intel: (97 commits) drm/i915: remove a superflous semi-colon drm/i915: Kill useless "Enable panel fitter" comments drm/i915: Remove extra "ring" from error message drm/i915: simplify the reduced clock handling for pch plls drm/i915: stop killing pfit on i9xx drm/i915: explicitly set up PIPECONF (and gamma table) on haswell drm/i915: set up PIPECONF explicitly for i9xx/vlv platforms drm/i915: set up PIPECONF explicitly on ilk-ivb drm/i915: find guilty batch buffer on ring resets drm/i915: store ring hangcheck action drm/i915: add batch bo to i915_add_request() drm/i915: change i915_add_request to macro drm/i915: add i915_gem_context_get_hang_stats() drm/i915: add struct i915_ctx_hang_stats drm/i915: Try harder to disable trickle feed on VLV drm/i915: fix up pch pll enabling for pixel multipliers drm/i915: hw state readout and cross-checking for shared dplls drm/i915: WARN on lack of shared dpll drm/i915: split up intel_modeset_check_state drm/i915: extract readout_hw_state from setup_hw_state ...
