Subject: Enable MP systems via cmd-line flag in fs.py.
X-Git-Tag: m5_2.0_beta2~73^2~10
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=05c487ef3ce6eb015bc8716df7e9caeedfe520da;p=gem5.git

Enable MP systems via cmd-line flag in fs.py.

configs/example/fs.py:
    Add flag for MP server systems.
src/python/m5/objects/AlphaConsole.py:
src/python/m5/objects/IntrControl.py:
    Change CPU from 'any' to 'cpu[0]' to work better with MP sytems.
tests/configs/tsunami-simple-atomic-dual.py:
tests/configs/tsunami-simple-timing-dual.py:
    Don't need to set console & intrcontrol cpu
    params anymore (default is fixed now).
