Subject: Add a few configuration DPRINTFs.
X-Git-Tag: m5_1.0_beta2~338
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a0f3ee7e1770138edd4ee65a2ce6ba2a017d792e;p=gem5.git

Add a few configuration DPRINTFs.
Fix handling of chars (uint8_ts) in serialization.
Minor cleanup.

sim/param.cc:
    Add specialization of showParam for char: output as ints, not as characters.
    Clean up comments a bit.
