Subject: [Qemu-devel] [PATCH 0/3] Simpletrace v2: Support multiple args, strings.
Date: Thu,  3 May 2012 23:26:33 +0530	[thread overview]
Message-ID: <1336067796-5730-1-git-send-email-harsh@linux.vnet.ibm.com> (raw)

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
