      drm/i915/gem: hide new uAPI behind CONFIG_BROKEN · 0a46be95
      Matthew Auld authored
      Treat it the same as the fake local-memory stuff, where it is disabled
      for normal kernels, in case some random UMD is tempted to use this. Once
      we have all the other bits and pieces in place, like the TTM conversion,
      we can turn this on for real.

      drm/i915/gem: clear userspace buffers for LMEM · 0e997a36
      Matthew Auld authored
      All userspace objects must be cleared when allocating the backing store,
      before they are potentially visible to userspace.  For now use simple
      CPU based clearing to do this for device local-memory objects, note that
      in the near future this will instead use the blitter engine.

      drm/i915/lmem: support optional CPU clearing for special internal use · 4f869f1d
      Matthew Auld authored
      For some internal device local-memory objects it would be useful to have
      an option to CPU clear the pages upon gathering the backing store. Note
      that this might be before the blitter is useable, which is the case for
      some internal GuC objects.

      drm/i915/uapi: implement object placement extension · 2459e56f
      Matthew Auld authored
      Add new extension to support setting an immutable-priority-list of
      potential placements, at creation time.
      
      If we use the normal gem_create or gem_create_ext without the
      extensions/placements then we still get the old behaviour with only
      placing the object in system memory.
      
      v2(Daniel & Jason):
          - Add a bunch of kernel-doc
          - Simplify design for placements extension

      drm/i915/uapi: introduce drm_i915_gem_create_ext · ebcb4029
      Matthew Auld authored
      Same old gem_create but with now with extensions support. This is needed
      to support various upcoming usecases.
      
      v2:(Chris)
          - Use separate ioctl number for gem_create_ext, instead of hijacking
            the existing gem_create ioctl, otherwise we run into the issue
            with being unable to detect if the kernel supports the new extension
            behaviour.
          - We now have gem_create_ext.flags, which should be zeroed.
          - I915_GEM_CREATE_EXT_SETPARAM value is now zero, since this is the
            index into our array of extensions.
          - Setup a "vanilla" object which we can directly apply our extensions
            to.
      v3:(Daniel & Jason)
          - drop I915_GEM_CREATE_EXT_SETPARAM. Instead just have each extension
            do one thing only, instead of generic setparam which can cover
            various use cases.
          - add some kernel-doc.

        - add a note for set/get caching stuff
        - add some more docs for existing query and extensions stuff
        - add an actual code example for regions query
        - bunch of other stuff
       (Jason)
        - uAPI change(!):
      	- try a simpler design with the placements extension
      	- rather than have a generic setparam which can cover multiple
      	  use cases, have each extension be responsible for one thing
      	  only
      v4:
       (Daniel)
        - add some more notes for ttm conversion
        - bunch of other stuff
       (Jason)
        - uAPI change(!):

      	  region_info, just keep the bare minimum needed for padding
      v5:
      (Jason)
        - for the upstream plan, add a requirement that we send the uAPI bits
          again for final sign off before turning it on for real
        - document how we intend to extend the rsvd bits for the region query
      (Kenneth)
        - improve the comment for the smem+lmem mmap mode and caching

      Changes since v1:
      - Add lockdep annotations during init, to ensure that lockdep is primed.
        This also fixes a false positive when reading /proc/lockdep_stats
        during module reload.

      drm/i915: Fix crash in auto_retire · ca419f40
      Stéphane Marchesin authored
      The retire logic uses the 2 lower bits of the pointer to the retire
      function to store flags. However, the auto_retire function is not
      guaranteed to be aligned to a multiple of 4, which causes crashes as
      we jump to the wrong address, for example like this:
