25 /* Maximum number of TREs in an IPA immediate command transaction */
29  * struct gsi_trans - a GSI transaction
31  * Most fields in this structure for internal use by the transaction core code:
33  * @channel_id: Channel number transaction is associated with
34  * @cancelled:	If set by the core code, transaction was cancelled
35  * @rsvd_count:	Number of TREs reserved for this transaction
37  * @len:	Number of bytes sent or received by the transaction
38  * @data:	Preserved but not touched by the core transaction code
43  * @completion:	Completed when the transaction completes
44  * @byte_count:	TX channel byte count recorded when transaction committed
45  * @trans_count: Channel transaction count when committed (for BQL accounting)
47  * The @len field is set when the transaction is committed.  For RX
55 	bool cancelled;			/* true if transaction was cancelled */
77  * @pool:	GSI transaction pool pointer
138  * @channel_id:	Channel the transaction is associated with
146  * gsi_channel_trans_alloc() - Allocate a GSI transaction on a channel
148  * @channel_id:	Channel the transaction is associated with
149  * @tre_count:	Number of elements in the transaction
152  * Return:	A GSI transaction structure, or a null pointer if all
160  * gsi_trans_free() - Free a previously-allocated GSI transaction
161  * @trans:	Transaction to be freed
166  * gsi_trans_cmd_add() - Add an immediate command to a transaction
167  * @trans:	Transaction
177  * gsi_trans_page_add() - Add a page transfer to a transaction
178  * @trans:	Transaction
187  * gsi_trans_skb_add() - Add a socket transfer to a transaction
188  * @trans:	Transaction
191  * Return:	0, or -EMSGSIZE if socket data won't fit in transaction.
196  * gsi_trans_commit() - Commit a GSI transaction
197  * @trans:	Transaction to commit
203  * gsi_trans_commit_wait() - Commit a GSI transaction and wait for it
205  * @trans:	Transaction to commit
215  * This is not a transaction operation at all.  It's defined here because
216  * it needs to be done in coordination with other transaction activity.
