-/* T5 and later support a new BAR2-based doorbell mechanism for Egress Queues.
- * The User Doorbells are each 128 bytes in length with a Simple Doorbell at
- * offsets 8x and a Write Combining single 64-byte Egress Queue Unit
- * (X_IDXSIZE_UNIT) Gather Buffer interface at offset 64. For Ingress Queues,
- * we have a Going To Sleep register at offsets 8x+4.
- *
- * As noted above, we have many instances of the Simple Doorbell and Going To
- * Sleep registers at offsets 8x and 8x+4, respectively. We want to use a
- * non-64-byte aligned offset for the Simple Doorbell in order to attempt to
- * avoid buffering of the writes to the Simple Doorbell and we want to use a
- * non-contiguous offset for the Going To Sleep writes in order to avoid
- * possible combining between them.

-/*
- To understand this stuff, an understanding of keys and all their bits is
- necessary. Every node in the trie has a key associated with it, but not
- all of the bits in that key are significant.
-
- Consider a node 'n' and its parent 'tp'.
-
- If n is a leaf, every bit in its key is significant. Its presence is
- necessitated by path compression, since during a tree traversal (when
- searching for a leaf - unless we are doing an insertion) we will completely
- ignore all skipped bits we encounter. Thus we need to verify, at the end of
- a potentially successful search, that we have indeed been walking the
- correct key path.
-
- Note that we can never "miss" the correct key in the tree if present by
- following the wrong path. Path compression ensures that segments of the key
- that are the same for all keys with a given prefix are skipped, but the
- skipped part *is* identical for each node in the subtrie below the skipped
- bit! trie_insert() in this implementation takes care of that - note the
- call to tkey_sub_equals() in trie_insert().
-
- if n is an internal node - a 'tnode' here, the various parts of its key
- have many different meanings.
-
- Example:
- _________________________________________________________________
- | i | i | i | i | i | i | i | N | N | N | S | S | S | S | S | C |
- -----------------------------------------------------------------
- 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
-
- _________________________________________________________________
- | C | C | C | u | u | u | u | u | u | u | u | u | u | u | u | u |
- -----------------------------------------------------------------
- 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
-
- tp->pos = 7
- tp->bits = 3
- n->pos = 15
- n->bits = 4
-
- First, let's just ignore the bits that come before the parent tp, that is
- the bits from 0 to (tp->pos-1). They are *known* but at this point we do
- not use them for anything.
-
- The bits from (tp->pos) to (tp->pos + tp->bits - 1) - "N", above - are the
- index into the parent's child array. That is, they will be used to find

+/* To understand this stuff, an understanding of keys and all their bits is
+ * necessary. Every node in the trie has a key associated with it, but not
+ * all of the bits in that key are significant.
+ *
+ * Consider a node 'n' and its parent 'tp'.
+ *
+ * If n is a leaf, every bit in its key is significant. Its presence is
+ * necessitated by path compression, since during a tree traversal (when
+ * searching for a leaf - unless we are doing an insertion) we will completely
+ * ignore all skipped bits we encounter. Thus we need to verify, at the end of
+ * a potentially successful search, that we have indeed been walking the
+ * correct key path.
+ *
+ * Note that we can never "miss" the correct key in the tree if present by
+ * following the wrong path. Path compression ensures that segments of the key
+ * that are the same for all keys with a given prefix are skipped, but the
+ * skipped part *is* identical for each node in the subtrie below the skipped
+ * bit! trie_insert() in this implementation takes care of that.
+ *
+ * if n is an internal node - a 'tnode' here, the various parts of its key
+ * have many different meanings.
+ *
+ * Example:
+ * _________________________________________________________________
+ * | i | i | i | i | i | i | i | N | N | N | S | S | S | S | S | C |
+ * -----------------------------------------------------------------
+ * 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16
+ *
+ * _________________________________________________________________
+ * | C | C | C | u | u | u | u | u | u | u | u | u | u | u | u | u |
+ * -----------------------------------------------------------------
+ * 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
+ *
+ * tp->pos = 22
+ * tp->bits = 3
+ * n->pos = 13
+ * n->bits = 4
+ *
+ * First, let's just ignore the bits that come before the parent tp, that is
+ * the bits from (tp->pos + tp->bits) to 31. They are *known* but at this
+ * point we do not use them for anything.
+ *
+ * The bits from (tp->pos) to (tp->pos + tp->bits - 1) - "N", above - are the
+ * index into the parent's child array. That is, they will be used to find
+ * 'n' among tp's children.
+ *
+ * The bits from (n->pos + n->bits) to (tn->pos - 1) - "S" - are skipped bits
+ * for the node n.
+ *
+ * All the bits we have seen so far are significant to the node n. The rest
+ * of the bits are really not needed or indeed known in n->key.
+ *
+ * The bits from (n->pos) to (n->pos + n->bits - 1) - "C" - are the index into

- * Telecommunications, page 6:
- * "A node is doubled if the ratio of non-empty children to all
- * children in the *doubled* node is at least 'high'."
- *
- * 'high' in this instance is the variable 'inflate_threshold'. It
- * is expressed as a percentage, so we multiply it with
- * tnode_child_length() and instead of multiplying by 2 (since the
- * child array will be doubled by inflate()) and multiplying
- * the left-hand side by 100 (to handle the percentage thing) we
- * multiply the left-hand side by 50.
- *
- * The left-hand side may look a bit weird: tnode_child_length(tn)
- * - tn->empty_children is of course the number of non-null children
- * in the current node. tn->full_children is the number of "full"
- * children, that is non-null tnodes with a skip value of 0.
- * All of those will be doubled in the resulting inflated tnode, so
- * we just count them one extra time here.
- *
- * A clearer way to write this would be:
- *
- * to_be_doubled = tn->full_children;
- * not_to_be_doubled = tnode_child_length(tn) - tn->empty_children -
- * tn->full_children;
- *
- * new_child_length = tnode_child_length(tn) * 2;
- *
- * new_fill_factor = 100 * (not_to_be_doubled + 2*to_be_doubled) /
- * new_child_length;
- * if (new_fill_factor >= inflate_threshold)
- *
- * ...and so on, tho it would mess up the while () loop.
- *
- * anyway,
- * 100 * (not_to_be_doubled + 2*to_be_doubled) / new_child_length >=
- * inflate_threshold
- *
- * avoid a division:
- * 100 * (not_to_be_doubled + 2*to_be_doubled) >=
- * inflate_threshold * new_child_length
- *
- * expand not_to_be_doubled and to_be_doubled, and shorten:
- * 100 * (tnode_child_length(tn) - tn->empty_children +
- * tn->full_children) >= inflate_threshold * new_child_length
- *
- * expand new_child_length:
- * 100 * (tnode_child_length(tn) - tn->empty_children +
- * tn->full_children) >=
- * inflate_threshold * tnode_child_length(tn) * 2
- *
- * shorten again:
- * 50 * (tn->full_children + tnode_child_length(tn) -
- * tn->empty_children) >= inflate_threshold *

+/* From "Implementing a dynamic compressed trie" by Stefan Nilsson of
+ * the Helsinki University of Technology and Matti Tikkanen of Nokia
+ * Telecommunications, page 6:
+ * "A node is doubled if the ratio of non-empty children to all
+ * children in the *doubled* node is at least 'high'."
+ *
+ * 'high' in this instance is the variable 'inflate_threshold'. It
+ * is expressed as a percentage, so we multiply it with
+ * tnode_child_length() and instead of multiplying by 2 (since the
+ * child array will be doubled by inflate()) and multiplying
+ * the left-hand side by 100 (to handle the percentage thing) we
+ * multiply the left-hand side by 50.
+ *
+ * The left-hand side may look a bit weird: tnode_child_length(tn)
+ * - tn->empty_children is of course the number of non-null children
+ * in the current node. tn->full_children is the number of "full"
+ * children, that is non-null tnodes with a skip value of 0.
+ * All of those will be doubled in the resulting inflated tnode, so
+ * we just count them one extra time here.
+ *
+ * A clearer way to write this would be:
+ *
+ * to_be_doubled = tn->full_children;
+ * not_to_be_doubled = tnode_child_length(tn) - tn->empty_children -
+ * tn->full_children;
+ *
+ * new_child_length = tnode_child_length(tn) * 2;
+ *
+ * new_fill_factor = 100 * (not_to_be_doubled + 2*to_be_doubled) /
+ * new_child_length;
+ * if (new_fill_factor >= inflate_threshold)
+ *
+ * ...and so on, tho it would mess up the while () loop.
+ *
+ * anyway,
+ * 100 * (not_to_be_doubled + 2*to_be_doubled) / new_child_length >=
+ * inflate_threshold
+ *
+ * avoid a division:
+ * 100 * (not_to_be_doubled + 2*to_be_doubled) >=
+ * inflate_threshold * new_child_length
+ *
+ * expand not_to_be_doubled and to_be_doubled, and shorten:
+ * 100 * (tnode_child_length(tn) - tn->empty_children +
+ * tn->full_children) >= inflate_threshold * new_child_length
+ *
+ * expand new_child_length:
+ * 100 * (tnode_child_length(tn) - tn->empty_children +
+ * tn->full_children) >=
+ * inflate_threshold * tnode_child_length(tn) * 2
+ *
+ * shorten again:
