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:

cli->mutex was inverted with reservations, and multiple reservations were used without a ticket, fix both. This commit had to be done after the previous commit, because otherwise ttm_eu_* calls would use a different seqno counter.. 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:

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:

Mutexes should not be acquired in interrupt context. While the trylock fastpath is arguably safe on all implementations, the slowpath unlock path definitely isn't. 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 ...
