[gem5-dev] Unix domain sockets for gdb/m5term connections
Hi foIks. On our network here at work, we have an issue where security processes will scan ports and blow up gem5 instances which happen to be listening for remote gdb or m5term connections. I was thinking it might be nice to make it so those connections could use Unix domain sockets instead of network sockets to prevent that issue. Does anybody have an opinion on that? Any recommendations as far as how something like that could be set up? I haven't looked at the actual code yet, but I was thinking of adding an option to gem5 itself to tell it to create the inodes named after where the thing connecting falls in the object hierarchy. m5term could potentially differentiate based on a flag or on the format of the thing it's being told to connect to. I'm not sure if gdb supports unix domain sockets so that could be a problem, although I haven't tried it yet either.

[gem5-dev] Alpha ISA compile for stream benchmark
Hello I am trying to run Gem5 in se mode with stream benchmark. I am able to run with x86 compile but not with alpha Isa ... It says fatal the object file not supported for this ISA (alpha)... Can any one tell me which GCC needs to be used ? Also in fs mode I have problems in getting dramsim2 latency number while running parsec benchmark.. any thought on what am missing ... Same modified dramsim2 works Well with marssx86 and gives bank latency numbers... Thanks for your help in advance.

syscall-emul: Hotfix for FreeBSD/Mac builds
The clone system call added in 236719892 relies on header files
from Linux systems. Obviously, this prevents compilation for
anyone using FreeBSD or Mac to compile the simulator. This
changeset is meant as a temporary fix to allow builds on
non-Linux systems until a proper solution is found.
