NBLog.h\nnow includes all of these new headers except Merger.h, which is managed\nexclusively by MediaLogService.\n\nOther changes:\n- changed NBLog from a class to a namespace\n- changed NBLog::thread_info_t.type to enum and replaced magic numbers\n- fixed some fragile build dependencies in libaudioclient and medialog\n\nNo other changes were made, and all functionalities that existed prior\nto this commit remain the same.\n\nTest: build, dumpsys media.log\nBug: 68148948\nChange-Id: I1ce6dcb7b30d004f90584edfad7103a89f7bab0c\n"

      "message": "NBLog: Make separate readers for dumping logs and histograms\n\nPrior to this commit, the dumping of log contents and histograms from\nPerformanceAnalysis were in conflict because histograms obtained data\nfrom the merger\u0027s buffer, and the merger used the same readers as the\nlog dumps. One read would consume the whole buffer, which would cause\neither a lossy dump or an lossy merge. Now, both operations can exist\nwithout loss of information from sharing the same reader.\n\nThe step of merging contents of each writer\u0027s local buffer into a bigger\nbuffer has effectively been removed. PerformanceAnalysis now directly\nreads from each writer\u0027s buffer instead of reading from the merger\u0027s\nbigger buffer.\n\nTest: dumpsys media.log -r\nBug: 68148948\nChange-Id: I6d8ea6a8f6a43555183a6d8f17af567506a102f1\n"

Eventually, the\nreaders for the two functionalities will need to be separated to avoid\nconflict. The dump of the merged buffer is also disabled, which removes\nthe dumping of histograms.\n\nThe new types added are monotonic thread cycle time, CPU thread cycle\ntime, CPU frequency, and latency (which will need to be specified in\nfurther detail later).
