Hi,
i try to use gem5 for a small project at the university. Since 4 weeks
i try to run parsec on gem5, but i am not abel to do this.
Ok first what i have done.
A: Download gem5.tarball -> ok no good idea...
B: get the gem5.stable repository from the server with mercurial
C: get the FS-files from the gem5 download page
D: get the Parsec-2.1 disk img, .rcS Script and the Linux 2.6.27
kernel img from http://www.cs.utexas.edu/~parsec_m5/
E: follow the instruction in the manual for the parsec benchmarks. Now
there is my first problem. The kernel.org page is offline. I think
this is not a problem, because of the linux 2.6.27 kernel. I think it
is compiled etc. so i just renamed the vmlinux....2.6.27 file into
vmlinux and replace the vmlinux file from the FS-file package.
Now i think every thing should work, but when i try to compile gem5 with
scons /build/ALPHA_FS/
a lot of seltests failed.
For example this one:
diff -ubrs -I '^command line:' -I '^M5 compiled ' -I '^M5 started ' -I
'^M5 executing on ' -I '^Simulation complete at' -I '^Listening for'
-I 'listening for remote gdb' --exclude=stats.txt --exclude=outdiff

build/ALPHA_FS/tests/debug/long/10.linux-boot/alpha/linux/tsunami-o3 >
build/ALPHA_FS/tests/debug/long/10.linux-boot/alpha/linux/tsunami-o3/outdiff
scons: *** Error 1

It also the tests take very long time, some hours.
I tried hard, so solve the problem by my self, but now i have no more
ideas, how to solve the problem.
By the way, when i try to boot linux i get this output:
$ ./build/ALPHA_FS/m5.debug configs/example/fs.py

after that nothing happens for 20h+
I think it is broken.
Thank you very much for your help.
