From: Gabe Black Date: Thu, 21 Feb 2019 00:36:57 +0000 (-0800) Subject: systemc: Add m5.systemc and m5.tlm python modules. X-Git-Tag: v19.0.0.0~1095 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9bc9b2408395f93297a38aa1f54df562291f7752;p=gem5.git systemc: Add m5.systemc and m5.tlm python modules. These will be how systemc and tlm APIs which are not attached to SimObjects will be exposed. This avoids having to artificially attach them to wrapping SimObjects for instance, which is a bit awkward and non-obvious. The python code which attaches the systemc and tlm modules to the m5 modules lives in src/python/m5/__init__.py, but the modules themselves live in src/systemc/python to keep all the systemc code grouped together. It might be a little confusing to have a small part of the glue that adds those modules in a separate place (__init__.py), but that is, as far as I can tell, unavoidable, and it's better in my opinion to keep the systemc code grouped together than to put it alongside the other python code and __init__.py.
