[Qemu-devel] [PATCH v3 0/3] Simpletrace v2: Support multiple args, strin


From: Harsh Prateek Bora
Subject: [Qemu-devel] [PATCH v3 0/3] Simpletrace v2: Support multiple args, strings.
Date: Tue, 12 Jun 2012 17:02:31 +0530

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

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.
  Update simpletrace.py for new log format
