From: Nathan Binkert Date: Fri, 22 Dec 2006 06:38:50 +0000 (-0800) Subject: Expose the C++ event queue to python via the python function X-Git-Tag: m5_2.0_beta3~224^2~34 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ecd1420341f6d96bd485cedf9b08a809d7e99176;p=gem5.git Expose the C++ event queue to python via the python function m5.internal.event.create(). It takes a python object and a Tick and calls process() when the Tick occurs. --HG-- extra : convert_revision : 5e4c9728982b206163ff51e6850a1497d85ad7a3 --- diff --git a/src/SConscript b/src/SConscript index 6f323b938..229418703 100644 --- a/src/SConscript +++ b/src/SConscript @@ -131,6 +131,8 @@ base_sources = Split(''' python/swig/init.cc python/swig/debug_wrap.cc python/swig/main_wrap.cc + python/swig/event_wrap.cc + python/swig/pyevent.cc sim/builder.cc sim/debug.cc diff --git a/src/python/SConscript b/src/python/SConscript index 1e49a18b2..df1464809 100644 --- a/src/python/SConscript +++ b/src/python/SConscript @@ -107,6 +107,7 @@ def swig_it(basename): swig_it('main') swig_it('debug') +swig_it('event') # Action function to build the zip archive.
