2013-04-23	x86: regressions: add switcher full test	Nilay Vaish

2013-04-22	tests: Add support for testing KVM-based CPUs	Andreas Sandberg
	This changeset adds support for initializing a KVM VM in the BaseSystem test class and adds the following methods in run.py: require_file -- Test if a file exists and abort/skip if not. require_kvm -- Test if KVM support has been compiled into gem5 (i.e., BaseKvmCPU exists) and the KVM device exists on the host.
2013-01-07	tests: Add CPU switching tests	Andreas Sandberg
	This changeset adds a set of tests that stress the CPU switching code. It adds the following test configurations: * tsunami-switcheroo-full -- Alpha system (atomic, timing, O3) * realview-switcheroo-atomic -- ARM system (atomic<->atomic) * realview-switcheroo-timing -- ARM system (timing<->timing) * realview-switcheroo-o3 -- ARM system (O3<->O3) * realview-switcheroo-full -- ARM system (atomic, timing, O3) Reference data is provided for the 10.linux-boot test case. All of the tests trigger a CPU switch once per millisecond during the boot process. The in-order CPU model was not included in any of the tests as it does not support CPU handover.
2013-01-07	config: Do not use hardcoded physmem in fs script	Andreas Hansson
	This patch generalises the address range resolution for the I/O cache and I/O bridge such that they do not assume a single memory. The patch involves adding a parameter to the system which is then defined based on the memories that are to be visible from the I/O subsystem, whether behind a cache or a bridge. The change is needed to allow interleaved memory controllers in the system.
2013-01-07	tests: Create base classes to encapsulate common test configurations	Andreas Sandberg
	Most of the test cases currently contain a large amount of duplicated boiler plate code. This changeset introduces a set of classes that encapsulates most of the functionality when setting up a test configuration. The following base classes are introduced: * BaseSystem - Basic system configuration that can be used for both SE and FS simulation. * BaseFSSystem - Basic FS configuration uni-processor and multi-processor configurations. * BaseFSSystemUniprocessor - Basic FS configuration for uni-processor configurations. This is provided as a way to make existing test cases backwards compatible. Architecture specific implementations are provided for ARM, Alpha, and X86.
