2014-09-02drm/vmwgfx: rework to new fence interface, v2Maarten Lankhorst
Use the new fence interface on vmwgfx too. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> --- Changes since v1: Fix a sleeping function called from invalid context in enable_signaling.
2014-09-02drm/vmwgfx: get rid of different types of fence_flags entirelyMaarten Lankhorst
Only one type was ever used. This is needed to simplify the fence support in the next commit. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com>
2014-09-01drm/radeon: use common fence implementation for fences, v4Maarten Lankhorst
Changes since v1: - Kill the sw interrupt dance, add and use radeon_irq_kms_sw_irq_get_delayed instead. - Change custom wait function, lockdep complained about it. Holding exclusive_lock in the wait function might cause deadlocks. Instead do all the processing in .enable_signaling, and wait on the global fence_queue to pick up gpu resets. - Process all fences in radeon_gpu_reset after reset to close a race with the trylock in enable_signaling. Changes since v2: - Small changes to work with the rewritten lockup recovery patches. Changes since v3: - Call radeon_fence_schedule_check when exclusive_lock cannot be acquired to always cause a wake up. - Reset irqs from hangup check. - Drop reading seqno in the callback, use cached value. - Fix indentation in radeon_fence_default_wait - Add a radeon_test_signaled function, drop a few test_bit calls. - Make to_radeon_fence global.

2014-09-01drm/ttm: kill off some members to ttm_validate_bufferMaarten Lankhorst
This reorders the list to keep track of what buffers are reserved, so previous members are always unreserved. This gets rid of some bookkeeping that's no longer needed, while simplifying the code some. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com>

2014-09-01drm/nouveau: add reservation to nouveau_gem_ioctl_cpu_prepMaarten Lankhorst
Apart from some code inside ttm itself and nouveau_bo_vma_del, this is the only place where ttm_bo_wait is used without a reservation. Fix this so we can remove the fence_lock later on.

2014-08-18drm/i915: fix HPD IRQ reenable work cancelationImre Deak
Atm, the HPD IRQ reenable timer can get rearmed right after it's canceled. Also to access the HPD IRQ mask registers we need to wake up the HW. Solve both issues by converting the reenable timer to a delayed work and grabbing a runtime PM reference in the work. By this we can also forgo canceling the timer during runtime suspend, since the only important thing there is that the HW is awake when we write the registers and that's ensured by the RPM ref. So do the cancelation only during driver unload time; this is also a requirement for an upcoming patch where we want to cancel all HPD related works only during system suspend and driver unload time, but not during runtime suspend. Note that there is still a race between the HPD IRQ reenable work and drm_irq_uninstall() during driver unload, where the work can reenable the HPD IRQs disabled by drm_irq_uninstall(). This isn't a problem since the HPD IRQs will still be effectively masked by the first level interrupt mask. v2-3: - unchanged v4: - use proper API for changing the expiration time for an already pending delayed work (Jani) Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (v2) Cc: stable@vger.kernel.org (3.16+) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
