摘要： Mechanisms are provided, in a data processing system having a processor and a transactional memory, for executing a transaction in the data processing system. These mechanisms execute a transaction comprising one or more instructions that modify at least a portion of the transactional memory. The transaction is suspended in response to a transaction suspend instruction being executed by the processor. A suspended block of code is executed in a non-transactional manner while the transaction is suspended. A determination is made as to whether an interrupt occurs while the transaction is suspended. In response to an interrupt occurring while the transaction is suspended, a transaction abort operation is delayed until after the transaction suspension is discontinued.

摘要： Mechanisms are provided for performing escape actions within transactions. These mechanisms execute a transaction comprising a transactional section and an escape action. The transactional section is comprised of one or more instructions that are to be executed in an atomic manner as part of the transaction. The escape action is comprised of one or more instructions to be executed in a non-transactional manner. These mechanisms further populate at least one actions list data structure, associated with a thread of the data processing system that is executing the transaction, with one or more actions associated with the escape action. Moreover, these mechanisms execute one or more actions in the actions list data structure based upon whether the transaction commits successfully or is aborted.

摘要： Mechanisms for executing a transaction in the data processing system are provided. A transaction checkpoint data structure is generated in internal registers of a processor. The transaction checkpoint data structure stores transaction checkpoint data representing a state of program registers at a time prior to execution of a corresponding transaction. The transaction, which comprises a first portion of code that is to be executed by the processor, is executed. An interrupt of the transaction is received while executing the transaction and, as a result, the transaction checkpoint data is stored to a data structure in a memory of the data processing system. A second portion of code is then executed. A state of the program registers is restored using the data structure in the memory of the data processing system in response to an event occurring causing a switch of execution of the processor back to execution of the transaction.

摘要： There is provided a method for detecting a conflict between a transaction and a TLB (Translation Lookaside Buffer) shootdown in a transactional memory in which a TLB shootdown operation message is received by a processor to invalidate at least one entry in a TLB of the processor corresponding to at least one page. The processor tracks pages touched by the transaction. The processor determines whether the received TLB shootdown operation message is associated with one of the touched pages. The processor aborts the transaction in response to determining that the received TLB shootdown operation message is associated with one of the touched pages.

摘要： Apparatus and methods for hardware assisted scheduling of software tasks in a computer system are disclosed. For example, a computer system comprises a first pool for maintaining a set of executable software threads, a first scheduler, a second pool for maintaining a set of active software threads, and a second scheduler. The first scheduler assigns a subset of the set of executable software threads to the set of active software threads and the second scheduler dispatches one or more threads from the set of active software threads to a set of hardware threads for execution. In one embodiment, the first scheduler is implemented as part of the operating system of the computer system, and the second scheduler is implemented in hardware.
