Abstract:
According to a first aspect, efficient data transfer operations can be achieved by: decoding by a processor device, a single instruction specifying a transfer operation for a plurality of data elements between a first storage location and a second storage location; issuing the single instruction for execution by an execution unit in the processor; detecting an occurrence of an exception during execution of the single instruction; and in response to the exception, delivering pending traps or interrupts to an exception handler prior to delivering the exception.

Abstract:
A processing device implementing tracking of deferred data packets in a debug trace architecture is disclosed. The processing device is to determine an order number corresponding to an order in which an instruction was executed relative to other executed instructions that correspond to an instruction type within a sequence of executed instructions, identify a first data packet corresponding to a first packet type and sequentially ordered, according to the order number, with respect to data packets of the first packet type within a data trace log, identify a second data packet corresponding to a second packet type and sequentially ordered, according to the order number, with respect to data packets of the second packet type within the data trace log, and map the identified first and second data packets to the instruction, wherein at least one of the first or second data packets was generated post-retirement of the instruction.
Abstract:
In one embodiment, a processor includes an execution unit and at least one last branch record (LBR) register to store address information of a branch taken during program execution. This register may further store a transaction indicator to indicate whether the branch was taken during a transactional memory (TM) transaction. This register may further store an abort indicator to indicate whether the branch was caused by a transaction abort. Other embodiments are described and claimed.
Abstract:
In accordance with embodiments disclosed herein, there is provided systems and methods for providing status of a processing device with a periodic synchronization point in an instruction tracing system. For example, the method may include generating a boundary packet based on a unique byte pattern in a packet log. The boundary packet provides a starting point for packet decode. The method may also include generating a plurality of state packets based on status information of the processor. The plurality of state packets follows the boundary packet when outputted into the packet log.
Abstract:
In an embodiment, a processor includes a core that is to include fetch logic to fetch instructions that include first instructions and a second instruction. The core also includes execution logic to execute the instructions. The execution logic is to retrieve an operand value that is one of an immediate value, a register value, and a memory value stored in a memory location, responsive to execution of the second instruction. The core also includes logic to output a packet that includes a representation of the operand value responsive to execution of the second instruction. The core also includes processor trace (PT) logic to generate a processor trace that includes a plurality of PT packets, where each PT packet correspond to an outcome of execution of a respective first instruction. The processor trace logic is further to include the packet within the processor trace. Other embodiments are described and claimed.
