From 2834c3e0140c3b0ed4422909dfa0607b7213d95d Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Mon, 8 Nov 2010 19:33:08 +0000 Subject: Add support for generating a systemtap tapset static probes This introduces generation of a qemu.stp/qemu-system-XXX.stp files which provides tapsets with friendly names for static probes & their arguments. Instead of probe process("qemu").mark("qemu_malloc") { printf("Malloc %d %p\n", $arg1, $arg2); } It is now possible todo probe qemu.system.i386.qemu_malloc { printf("Malloc %d %p\n", size, ptr); } There is one tapset defined per target arch. * Makefile: Generate a qemu.stp file for systemtap * tracetool: Support for generating systemtap tapsets Signed-off-by: Daniel P.
