perf intel-pt/bts: Tidy instruction buffer size usage

2016-10-24T13:31:32Z

Tidy instruction buffer size usage in preparation for copying the instruction bytes onto samples. The instruction buffer is presently used for debugging, so rename its size macro from INTEL_PT_INSN_DBG_BUF_SZ to INTEL_PT_INSN_BUF_SZ, and use it everywhere. Note that the maximum instruction size is 15 which is a less efficient size to copy than 16, which is why a separate buffer size is used.

perf intel-pt: Make logging slightly more efficient

2015-09-28T19:45:26Z

Logging is only used for debugging. Use macros to save calling into the functions only to return immediately when logging is not enabled.

perf tools: Add Intel PT log

2015-08-17T14:11:36Z

Add a facility to log Intel Processor Trace decoding. The log is intended for debugging purposes only. The log file name is "intel_pt.log" and is opened in the current directory. The log contains a record of all packets and instructions decoded and can get very large (10 MB would be a small one).
