* Output JSON file for post-processing * Debug utility for parsing the SCSI data * Prototype app for parsing scsi captures * correct arg parsing * output html * Cleanupt html output * Add missing include * Allow compilation on non-Linux platforms * Refactored scsimon to be in multiple files * Refactored away * Restructured scsimon into smaller pieces * Added ability to read in pre-generated .json file and re-parse it * Delete scsiparse.cpp * Fix argument parsing and code cleanup * Ran vscode c++ formatting utility * Restore the -Wno-psabi flag for Linux only * Address compiler warnings * Updated to use C++ style ostreams * Cleanup conversion to c++ style ostreams * Updated to use ofstream instead of fprintf * Delete src/raspberrypi/scsimon directory Co-authored-by: akuker <akuker@gmail.com>
