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.

2018-01-10arch-riscv: Make use of ImmOp's polymorphismAlec Roelke
This patch makes use of ImmOp's polymorphism to remove unnecessary casting from the implementations of arithmetic instructions with immediate operands and to remove the CUIOp format by combining it with the CIOp format (compressed arithmetic instructions with immediate operands). 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.

2017-05-02python: 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.

2017-03-16tests: Warn not fail when reading invalid pickle status filesNikos Nikoleris
With this change, the test script will output a warning when it reads an incomplete (e.g., when a regression is still running) or corrupt status file instead of throwing an exception. When the scipt is used to show the results the corrupt file is skipped; when it is used to test if all regressions run successfully it will return an error value (2).

2017-02-27base: Refactor logging to make log level selection cleanerAndreas Sandberg
It's currently possible to change the log level in gem5 by tweaking a set of global variables. These variables are currently exposed to Python using SWIG. This mechanism is far from ideal for two reasons: First, changing the log level requires that the Python world enables or disables individual levels. Ideally, this should be a single call where a log level is selected. Second, exporting global variables is poorly supported by most Python frameworks. SWIG puts variables in their own namespace and PyBind doesn't seem to support it at all. This changeset refactors the logging code to create a more abstract interface. Each log level is associated with an instance of a Logger class. This class contains common functionality, an enable flag, and a verbose flag. Available LogLevels are described by the LogLevel class. Lower log levels are used for more critical messages (PANIC being level 0) and higher levels for less critical messages. The highest log level that is printed is controlled by calling Logger:setLevel().

The EIOProcess class was removed recently and it was the only other class which derived from Process. Since every Process invocation is also a LiveProcess invocation, it makes sense to simplify the organization by combining the fields from LiveProcess into Process.
2017-02-14mem: Update DRAM configuration namesWendy Elsasser
Names of DRAM configurations were updated to reflect both the channel and device data width. Previous naming format was: <DEVICE_TYPE>_<DATA_RATE>_<CHANNEL_WIDTH> The following nomenclature is now used: <DEVICE_TYPE>_<DATA_RATE>_<n>x<w> where n = The number of devices per rank on the channel x = Device width Total channel width can be calculated by n*w Example: A 64-bit DDR4, 2400 channel consisting of 4-bit devices: n = 16 w = 4 The resulting configuration name is: DDR4_2400_16x4 Updated scripts to match new naming convention. Added unique configurations for DDR4 for: 1) 16x4 2) 8x8 3) 4x16 Change-Id: Ibd7f763b7248835c624309143cb9fc29d56a69d1 Reviewed-by: Radhika Jagtap <radhika.jagtap@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com>

The system calls tested in rv64i.cpp in RISC-V's insttest suite have different behavior depending on the operating system and file system they are run on. This patch ignores the output of those tests and only ensures that the instructions in RV64I complete successfully. [Change deletion of ECALL test to block comment.] [Restore ECALL test but remove test output to test only for completion without error.] [Update patch description and again try to push EMPTY files for rv64i tests.]
