Counters For Ensuring Transactional Ordering in I/O Agent
Techniques are disclosed relating to an I/O agent circuit. The I/O agent circuit may include a transaction pipeline and a pool of counters. The I/O agent circuit may initialize a first counter included in the pool of counters with an initial counter value. The I/O agent circuit may assign the first...

| description | Techniques are disclosed relating to an I/O agent circuit. The I/O agent circuit may include a transaction pipeline and a pool of counters. The I/O agent circuit may initialize a first counter included in the pool of counters with an initial counter value. The I/O agent circuit may assign the first counter to a specific transaction type. The I/O agent circuit may increment the first counter as a part of allocating a transaction of a transaction type included in a set of transaction types different than the specific transaction type. Based on receiving a transaction request to process a first transaction of the specific transaction type, the I/O agent circuit may bind the first transaction to the first counter. The I/O agent circuit may issue the first transaction to the transaction pipeline based on a counter value stored by the first counter matching the initial counter value. |
