2019-01-31tests: Add a helper to run external scriptsAndreas Sandberg
Some tests are really just a wrapper around a test script in configs/. Add a helper method to wrap these scripts to make sure they are executed in a consistent environment. This wrapper sets up a global environment that is identical to that created by main() when it executes the script. Unlike the old wrappers, it updates the module search path to make relative imports work correctly in Python 3.

2018-09-12cpu: Replace the fastmem with a new CPU modelAndreas Sandberg
The AtomicSimpleCPU used to be able to access memory directly to speed up simulation if no caches are used. This is fine as long as no switching between CPU models is required. In order to switch to a new CPU model that requires caches, we currently need to checkpoint the system and restore it into a new configuration. The new 'atomic_noncaching' memory mode provides a solution that avoids this issue since caches are bypassed in this mode. This changeset removes the old fastmem option from the AtomicSimpleCPU and introduces a new CPU, NonCachingSimpleCPU, which derives from the AtomicSimpleCPU. The NonCachingSimpleCPU uses the same mechanism as the AtomicSimpleCPU used to use when accessing memory in when fastmem was enabled. This changeset also introduces a new switcheroo test that tests switching between a NonCachingSimpleCPU and a TimingSimpleCPU with caches.

2018-06-15tests,style: add RISC-V assembly testsTuan Ta
This patch adds a subset (rv64*) of RISC-V assembly tests. The original riscv-test project can be found here: https://github.com/riscv/riscv-tests. The riscv-test project is under the BSD license (https://github.com/riscv/riscv-tests/blob/master/LICENSE) and is maintained separately from gem5 project. The tests have been slightly modified to work in gem5 SE mode: (1) Removed a trap handler used in riscv-tests for bare-metal systems (2) Instead of throwing an exception, the tests call the exit syscall with the exit code of - '0' if SUCCESS - Failed test case's number (non-zero) if FAILURE The exit code can be captured after a simuation completes. In addition to original RISC-V assembly tests, this patch adds several assembly tests specifically for AMO, LR, SC and system calls. Those tests target a multi-core system. (1) rv64uamt: multi-threaded tests for A-extension instructions (2) rv64samt: multi-threaded tests for clone and futex system calls This patch also makes the style checker ignore RISC-V assembly test directory. The assembly tests are maintained in an external project that does not follow the gem5 coding conventions. Please find more details in the README file included in this patch.

Interestingly, RISC-V specifies that instructions with unsigned immediate operands still need to sign-extend the immediates from 12 (or 20) bits to 64 bits, so that is left alone.

2017-06-13scons: Make MOESI_CMP_directory the default ARM ruby protocolNikos Nikoleris
Previously ARM binaries were by default compiled with the MI_example protocol. The MI_example protocol cannot properly support load/store exclusive instructions and therefore it cannot be used to simulate multicore ARM systems. This change changes to MOESI_CMP_directory as the default ruby protocol for ARM systems.

2017-05-02python: Use PyBind11 instead of SWIG for Python wrappersAndreas Sandberg
Use the PyBind11 wrapping infrastructure instead of SWIG to generate wrappers for functionality that needs to be exported to Python. This has several benefits: * PyBind11 can be redistributed with gem5, which means that we have full control of the version used. This avoid a large number of hard-to-debug SWIG issues we have seen in the past. * PyBind11 doesn't rely on a custom C++ parser, instead it relies on wrappers being explicitly declared in C++. The leads to slightly more boiler-plate code in manually created wrappers, but doesn't doesn't increase the overall code size. A big benefit is that this avoids strange compilation errors when SWIG doesn't understand modern language features. * Unlike SWIG, there is no risk that the wrapper code incorporates incorrect type casts (this has happened on numerous occasions in the past) since these will result in compile-time errors. As a part of this change, the mechanism to define exported methods has been redesigned slightly. New methods can be exported either by declaring them in the SimObject declaration and decorating them with the cxxMethod decorator or by adding an instance of PyBindMethod/PyBindProperty to the cxx_exports class variable. The decorator has the added benefit of making it possible to add a docstring and naming the method's parameters. The new wrappers have the following known issues: * Global events can't be memory managed correctly. This was the case in SWIG as well.
