Lionel Landwerlin 829699ba63 anv: implement shareable timeline semaphores
This implements timeline semaphores using a new type of dma-fence
stored into drm-syncobjs. We use a thread to implement delayed
submissions.

v2: Drop cloning of temporary semaphores and just transfer their ownership (Jason)
    Drain queue when dealing with binary semaphore
    Ensure we don't submit to the thread as long as we don't need to

v3: Use __u64 not uintptr_t for kernel pointers
    Fix commented code for INTEL_DEBUG=bat
    Set DRM_I915_GEM_EXECBUFFER_EXT_TIMELINE_FENCES in timeline fence execbuf extension
    Add new anv_queue_set_lost()
    Drop multi queue stuff meant for the fake multi queue patch
    Rework temporary syncobj handling
    Don't use syncobj when not available (DeviceWaitIdle/CreateDevice)
    Use ANV_MULTIALLOC
    And a few more tweaks...

v4: Drop drained condition helper (Lionel)
    Fix missing EXEC_OBJECT_WRITE on BOs we want to wait on (Jason)

v5: Add missing device->lost_reported in _anv_device_report_lost (Lionel)
    Fix missing free on submit->simple_bo (Lionel)
    Don't drop setting the device in lost state on QueueSubmit error (Jason)
    Store submit->fence_bos as an array of uintptr_t (Jason)

v6: condition device->has_thread_submit to i915 & core DRM support (Jason)

v7: Fix submit->in_fence leakage on error (Jason)
    Keep dummy semaphore with no thread submission (Jason)

v8: Move ownership of submit->out_fence to submit (Jason)

v9: Don't forget to read the VkFence's syncobj binary payload (Lionel)

v10: Take the mutex lock on anv_gem_close() (Jason/Lionel)

v11: Fix void* -> u64 cast on 32bit (Lionel)

v12: Rebase after BO backed timeline semaphore (Lionel)

v13: Fix missing snippets lost after rebase (Lionel)

v14: Drop update_binary usage (Lionel)

v15: Use ANV_MULTIALLOC (Lionel)

v16: Fix some realloc issues (Ivan)

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
