Hi
In order to use Intel PT with jitdump, changes are needed
because Intel PT uses TSC as a timestamp not the monotonic clock.
These patches enable TSC to be used which allows the following
using a simple HelloWorld java app:
perf record -e intel_pt//u -o java.perf.data java
-agentpath:/home/ahunter/git/linux-perf/tools/perf/jvmti/libjvmti.so
HelloWorldApp
perf inject -i java.perf.data --jit -o java.perf.data.jitted
perf report -i java.perf.data.jitted
perf script -i java.perf.data.jitted | less
Note, there will be some decoder errors because not all the
generated code is reported to the agent.
Lazily, there is also an unrelated patch:
perf tools: Use 64-bit shifts with (TSC) time conversion"
Adrian Hunter (8):
perf inject: Hit all DSOs for AUX data in JIT and other cases
perf session: Simplify tool stubs
perf tools: Add time conversion event
perf jit: Let jit_process() return errors
perf jit: Move clockid validation
perf jit: Add support for using TSC as a timestamp
perf intel-pt/bts: Define JITDUMP_USE_ARCH_TIMESTAMP
perf tools: Use 64-bit shifts with (TSC) time conversion
