    gallium/freedreno: move cast to avoid integer overflow
    
    Previously, the bitshift would be performed on a simple int (32 bits on
    most systems), overflow, and then be cast to 64 bits.

    freedreno: drop needs_rb_fbd
    
    We need to emit RB_FRAME_BUFFER_DIMENSION once per batch.. tracking this
    in fd_context is wrong when the gmem code executes asynchronously from
    the flush_queue worker.  But in fact we don't really need to track it at
    all.  We cannot assume previous value at the beginning of the batch
    (because of other processes potentially using the GPU), so just drop the
    tracking and emit it in _tile_init().

    freedreno: move needs_wfi into batch
    
    This is also used in gmem code, which executes from the "bottom half"
    (ie. from the flush_queue worker thread), so it cannot be in fd_context.

    freedreno: drop mem2gmem/gmem2mem query stages
    
    They weren't really used, and it gets somewhat more complicated to deal
    with if batches are flushed asynchronously (on another thread).  So just
    drop them, and move _query_set_state(NULL) call into batch (so it is not
    happening on background thread).

    freedreno: threaded batch flush
    
    With the state accessed from GMEM+submit factored out of fd_context and
    into fd_batch, now it is possible to punt this off to a helper thread.
    And more importantly, since there are cases where one context might
    force the batch-cache to flush another context's batches (ie. when there
    are too many in-flight batches), using a per-context helper thread keeps
    various different flushes for a given context serialized.
    
    TODO as with batch-cache, there are a few places where we'll need a
    mutex to protect critical sections, which is completely missing at the
    moment.

    freedreno: track batch/blit types
    
    Add a bit of extra book-keeping about blits and back-blits (from
    resource shadowing).  If the app uploads all mipmap levels, as opposed
    to uploading the first level and then glGenerateMipmap(), we can discard
    the back-blit (as opposed to being naive and shadowing the resource for
    each mipmap level).  Also, after a normal blit, we might as well flush
    the batch immediately, since there is not likely to be further rendering
    to the surface.

    freedreno: re-order support for hw queries
    
    Push query state down to batch, and use the resource tracking to figure
    out which batch(es) need to be flushed to get the query result.
    
    This means we actually need to allocate the prsc up front, before we
    know the size.  So we have to add a special way to allocate an un-
    backed resource, and then later allocate the backing storage.

    freedreno: use prsc for hw queries
    
    Switch to using a pipe_resource (rather than an fd_bo directly) for hw
    query result buffers.  This is first step towards making queries work
    properly with reordered batches, since we'll need the additional
    dependency tracking to know which batches to flush.

    freedreno: support discarding previous rendering in special cases
    
    Basically, to "DCE" blits triggered by resource shadowing, in cases
    where the levels are immediately completely overwritten.  For example,
    mid-frame texture upload to level zero triggers shadowing and back-blits
    to the remaining levels, which are immediately overwritten by
    glGenerateMipmap().

    freedreno: shadow textures if possible to avoid stall/flush
    
    To make batch re-ordering useful, we need to be able to create shadow
    resources to avoid a flush/stall in transfer_map().  For example,
    uploading new texture contents or updating a UBO mid-batch.  In these
    cases, we want to clone the buffer, and update the new buffer, leaving
    the old buffer (whose reference is held by cmdstream) as a shadow.
    
    This is done by blitting the remaining other levels (and whatever part
    of current level that is not discarded) from the old/shadow buffer to
    the new one.

    freedreno: add batch-cache and batch reordering
    
    Note that I originally also had a entry-point that would construct a key
    and do lookup from a pipe_surface.  I ended up not needing that (yet?)
    but it is easy-enough to re-introduce later if we need it for the blit
    path.
    
    For now, not enabled by default, but can be enabled (on a3xx/a4xx) with
    FD_MESA_DEBUG=reorder.

    freedreno: move more batch related tracking to fd_batch
    
    To flush batches out of order, the gmem code needs to not depend on
    state from fd_context (since that may apply to a more recent batch).
    So this all moves into batch.
    
    The one exception is the gmem/pipe/tile state itself.  But this is
    only used from gmem code (and batches are flushed serially).  The
    alternative would be having to re-calculate GMEM layout on every
    batch, even if the dimensions of the render targets are the same.
    
    Note: This opens up the possibility of pushing gmem/submit into a
    helper thread.

    freedreno: introduce fd_batch
    
    Introduce the batch object, to track a batch/submit's worth of
    ringbuffers and other bookkeeping.  In this first step, just move
    the ringbuffers into batch, since that is mostly uninteresting
    churn.
    
    For now there is just a single batch at a time.  Note that one
    outcome of this change is that rb's are allocated/freed on each
    use.  But the expectation is that the bo pool in libdrm_freedreno
    will save us the GEM bo alloc/free which was the initial reason
    to implement a rb pool in gallium.
    
    The purpose of the batch is to eventually facilitate out-of-order
    rendering, with batches associated to framebuffer state, and
    tracking the dependencies on other batches.
