List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: stefanha@gmail.com, qemu-devel@nongnu.org, stefanha@linux.vnet.ibm.com Cc: Harsh Prateek Bora Existing simpletrace backend allows to trace at max 6 args and does not support strings. This newer tracelog format gets rid of fixed size records and therefore allows to trace variable number of args including strings. Sample trace: v9fs_version 0.000 tag=0xffff id=0x64 msize=0x2000 version=9P2000.L v9fs_version_return 6.705 tag=0xffff id=0x64 msize=0x2000 version=9P2000.L v9fs_attach 174.467 tag=0x1 id=0x68 fid=0x0 afid=0xffffffffffffffff uname=nobody aname= v9fs_attach_return 4720.454 tag=0x1 id=0x68 type=0xffffffffffffff80 version=0x4f2a4dd0 path=0x220ea6 v6: - Corrected flush condition and reverted un-necessary check in get_trace_record - moved idx refresh out of while-loop in writeout_thread, see comments in code. v5: - Addressed Stefan's review comments on v4 series. - Inroduced code to handle corrupted records due to racing tracers. v4: - removed unused safe_strlen interface (missed in v3). v3: - Addressed Stefan's review comments on v2 series v2: - moved elimination of st_print_trace to 1/3 patch - use sizeof(TraceRecord) for #define ST_REC_HDR_LEN v1: - Simpletrace v2 for the new (pythonized) tracetool Harsh Prateek Bora (3): monitor: remove unused do_info_trace Simpletrace v2: Support multiple arguments, strings.
