Mechanism for program-assisted tracing actions
Issued US 7568185
A method for tracing an instrumented application, including loading the instrumented application into a kernel level to obtain a corresponding instrumented process, registering a helper action with a tracing framework, tracing the instrumented process using the tracing framework, wherein tracing comprises triggering a probe in the instrumented process, determining whether the helper action is associated with the probe, and performing the helper action if the helper action is associated with the…

Method and system for creation and use of embedded trace description
Issued US 7409677
A method of generating an embedded file involving embedding a plurality of probe calls into source code to obtain embedded source code, compiling the embedded source code to generate object code including a probe relocation for each of the plurality of probe calls, post processing the object code to obtain a plurality of modified object code, wherein the plurality of modified object code includes object code containing a no-operation instruction in place of the probe relocation and object code…

Mechanism for lossless tracing in an arbitrary context
Issued US 7305662
A method for tracing an instrumented program, including triggering a probe in the instrumented program, obtaining an original instruction associated with the probe, loading the original instruction into a scratch space, and executing the original instruction in the scratch space using the thread, wherein executing the original instruction results in placing the instrumented program in a state equivalent to natively executing the original instruction.

Mechanism for lossless tracing in an architecture having a delay slot
Issued EU 7305661
A method for tracing an instrumented program using a thread, including transferring control of the instrumented program to a trap handler to obtain an original instruction associated with a probe, loading the original instruction into a scratch space, setting a program counter to point to the scratch space, setting a next program counter to point to a next instruction, and executing the original instruction in the scratch space using the thread, wherein executing the original instruction…
