      drm/i915: Flush buffer pools on driver remove · 74af1e2c
      Janusz Krzysztofik authored
      We currently do an explicit flush of the buffer pools within the call path
      of drm_driver.release(); this removes all buffers, regardless of their age,
      freeing the buffers' associated resources (objects, address space areas).
      However there is other code that runs within the drm_driver.release() call
      chain that expects objects and their associated address space areas have
      already been flushed.
      
      Since buffer pools auto-flush old buffers once per second in a worker
      thread, there's a small window where if we remove the driver while there
      are still objects in buffers with an age of less than one second, the
      assumptions of the other release code may be violated.
      
      By moving the flush to driver remove (which executes earlier via the
      pci_driver.remove() flow) we're ensuring that all buffers are flushed and
      their associated objects freed before some other code in
      pci_driver.remove() flushes those objects so they are released before
      _any_ code in drm_driver.release() that check completness of those
      flushes executes.
      
      v2: Reword commit description as suggested by Matt.

      drm/i915/guc, docs: Fix pdfdocs build error by removing nested grid · 017792a0
      Akira Yokosawa authored
      Nested grids in grid-table cells are not specified as proper ReST
      constructs.
      Commit 572f2a5c ("drm/i915/guc: Update firmware to v62.0.0")
      added a couple of kerneldoc tables of the form:
      
        +---+-------+------------------------------------------------------+
        | 1 |  31:0 |  +------------------------------------------------+  |
        +---+-------+  |                                                |  |
        |...|       |  |  Embedded `HXG Message`_                       |  |
        +---+-------+  |                                                |  |
        | n |  31:0 |  +------------------------------------------------+  |
        +---+-------+------------------------------------------------------+
      
      For "make htmldocs", they happen to work as one might expect,
      but they are incompatible with "make latexdocs" and "make pdfdocs",
      and cause the generated gpu.tex file to become incomplete and
      unbuildable by xelatex.
      
      Restore the compatibility by removing those nested grids in the tables.
      
      Size comparison of generated gpu.tex:
      
                        Sphinx 2.4.4  Sphinx 4.2.0
        v5.14:               3238686       3841631
        v5.15-rc1:            376270        432729
        with this fix:       3377846       3998095
