Subject: Ruby: Ensure snoop requests are sent using sendTimingSnoopReq
X-Git-Tag: stable_2012_06_28~95
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=15e28c5ba6ef0a436d05468e3113304987257b0b;p=gem5.git

Ruby: Ensure snoop requests are sent using sendTimingSnoopReq

This patch fixes a bug that caused snoop requests to be placed in a
packet queue. Instead, the packet is now sent immediately using
sendTimingSnoopReq, thus bypassing the packet queue and any normal
responses waiting to be sent.
