摘要： An apparatus, and computer program product are disclosed in a processor for dynamically, during runtime, allocating memory for in-memory hardware tracing. The processor is included within a data processing system. The processor includes multiple processing units that are coupled together utilizing a system bus. The processing units include a memory controller that controls a system memory. A particular size of the system memory is determined that is needed for storing trace data. A hardware trace facility requests, dynamically after the data processing system has completed booting, the particular size of the system memory to be allocated to the hardware trace facility for storing trace data that is captured by the hardware trace facility. The firmware selects particular locations within the system memory. All of the particular locations together are the particular size. The firmware allocates the particular locations for use exclusively by the hardware trace facility.

摘要： An apparatus and computer program product are disclosed for performing in-memory hardware tracing in a processor using an existing system bus. The processor includes multiple processing units that are coupled together utilizing the system bus. The processing units include a memory controller that controls a system memory. Information is transmitted among the processing units utilizing the system bus. The information is formatted according to a standard system bus protocol. Hardware trace data is captured utilizing a hardware trace facility that is coupled directly to the system bus. The system bus is utilized for transmitting the hardware trace data to the memory controller for storage in the system memory. The memory controller is coupled directly to the system bus. The hardware trace data is formatted according to the standard system bus protocol for transmission via the system bus.
