Hi Sandeepa,
Yes, the Foundation model is very slow. I have read that there has been some work to get aarch64 support in qemu, but I have not personally tried it:
http://news.opensuse.org/2013/10/01/suse-speeds-up-building-aarch64-software-in-qemu/
For systemtap your best bet is to use a git clone which has the current aarch64 patches:
git clone git://sourceware.org/git/systemtap.git
Then build (you may need to do a "yum-builddep systemtap" as root to pull in dependencies that systemtap needs to build):
cd systemtap
./configure --disable-docs
make
make install
At this point should have a systemtap that will build stuff for aarch64
For the current state of aarch64 package you can look at what is in http://arm-temp.ausil.us/pub/fedora-arm/stage4/
Each of the packages is in a subdirectory. You should be able to do something like the following to get the sources:
wget http://arm-temp.ausil.us/pub/fedora-arm/stage4/kernel-3.12.0-0.rc4.git0.1.x2.fc19/kernel-3.12.0-0.rc4.git0.1.x2.fc19.src.rpm
rpm -Uvh kernel*.src.rpm
cd rpmbuild/SPECS
yum-builddep kernel
rpmbuild -bp kernel.spec
Generally when fedora builds kernels it produces a /boot/config-`uname -r` file describing the configure used to build the kernel. This is in the kernel rpm. I don't recall if the kernel rpm is installed in the basic aarch64 image. You may need to do a "yum install kernel" to get that installed on the machine.
