Panagiotis Grivas <griva <at> ceid.upatras.gr> writes:CC,CFLAGS,and
LDFLAGS
Hi! I am new to gem5, i want to get a Alpha executable of FFT (splash
benchmarks) using alpha cross compiler. I follow the the Guide is
aimed
at the M5 beginners (gem5.org) by modifying CC, CFLAGS, and LDFLAGS,
but
i am getting: "make: *** [fft.o] Error 127". Can anyone give me
instractions (full steps) in order to get the executable;
Thanks in advance!
wget
http://www.m5sim.org/dist/current/alphaev67-unknown-linux-gnu.tar.bz2
tar -xjvf alphaev67-unknown-linux-gnu.tar.bz2
(This is for 64 bit Ubuntu,if your Ubuntu is 32 bit,download
here:http://www.gem5.org/Download)
Change Makefile.config to use the crosscompiler by modifying
CC,CFLAGS,and
LDFLAGS
cc:=/path/to/alphaev67-unknown-linux-gnu/bin/alphaev67-unknown-linux-gnu-
gcc
CFLAGS:=$(CFLAGS)
-I/path/to/alphaev67-unknown-linux-gnu/alphaev67-unknown-
linux-gnu/sys-root/usr/include
LDFLAGS:=$(LDFLAGS) -L/path/to/alphaev67-unknown-linux-gnu/alphaev67-
unknown-linux-gnu/lib/
You also need to modify the Makefile to compile statically,since the
disk
image doesn't have the correct libraries to dynamically link to.
CFLAGS := $(CFLAGS) -static -static-libgcc
Then,cd benchmark and make.
Run FFT in M5:
1)mount -o loop,offset=32256 linux-parsec-2-1-m5.img /mnt/m5_disk(make
m5_disk first)
mkdir -p /mnt/m5_disk/benchmarks/
cp FFT /mnt/m5_disk/benchmarks/ (cd directory of benchmarks)
2)add a fft benchmark to configs/common/Benchmarks.py.Add the following
data to the Benchmarks data structure:
'fft': [SysConfig('fft.rcS','512MB')],
3)make the rcS script at configs/boot/fft.rcS.This is the script m5
will
run when it boots linux
#! /bin/sh
cd benchmarks
Echo "Running FFT now..."
./FFT -t -p1
#Gracefully exit M5
/sbin/m5 exit
Now run M5:
./build/ALPHA/m5.opt configs/example/fs.py -n 1 -b fft
To check the progress of your simulation,you can telnet into the
booting
linux machine using m5term.Or you can wait until it's done and examine
m5out/system.terminal.At the bottom you should see TEST PASSED
