perf jvmti: Plug compilation into perf build

2016-11-14T15:42:47+00:00

Compile jvmti agent as part of the perf build. The agent library is called libperf-jvmti.so and is installed in default place together with other files: $ make libperf-jvmti.so BUILD: Doing 'make -j4' parallel build ...

perf jit: Remove unecessary padding in jitdump file

2016-10-24T14:07:38+00:00

This patch removes all the string padding generated in the jitdump file. They are not necessary and were adding unnecessary complexity. Modern processors can handle unaligned accesses quite well. The perf.data/ jitdump file are always post-processed, no need to add extra complexity for no real gain.

perf jit: Improve error messages from JVMTI

2016-10-24T14:07:37+00:00

This patch improves the usefulness of error messages generated by the JVMTI interfac.e This can help identify the root cause of a problem by printing the actual error code. The patch adds a new helper function called print_error().

perf jit: Fix build issue on Ubuntu

2016-10-17T14:25:34+00:00

When building on Ubuntu 16.04, I get the following error: Makefile:49: *** the openjdk development package appears to me missing, install and try again. Stop. The problem is that update-java-alternatives has multiple spaces between fields, and cut treats each space as a new delimiter: java-1.8.0-openjdk-ppc64el 1081 /usr/lib/jvm/java-1.8.0-openjdk-ppc64el Fix this by using awk, which handles this fine.

perf jit: Remove some no-op error handling

2016-07-18T15:20:00+00:00

The 'info.e_machine' struct member is an uint16_t so 'm' is never less than zero. It looks like this was maybe left over code from earlier versions so I've just removed it.

perf jit: Add support for using TSC as a timestamp

2016-04-01T21:42:55+00:00

Intel PT uses TSC as a timestamp, so add support for using TSC instead of the monotonic clock. Use of TSC is selected by an environment variable "JITDUMP_USE_ARCH_TIMESTAMP" and flagged in the jitdump file with flag JITDUMP_FLAGS_ARCH_TIMESTAMP.
