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().

2016-11-30riscv: [Patch 8/5] Added some regression tests to RISC-VAlec Roelke
This patch is the eighth patch in a series adding RISC-V to gem5, and third of the bonus patches to the original series of five. It adds some regression tests to RISC-V. Regression tests included: - se/00.hello - se/02.insttest (split into several binaries which are not included due to large size) The tests added to 00.insttest will need to be build manually; to facilitate this, a Makefile is included. The required toolchain and compiler (riscv64-unknown-elf-gcc) can be built from the riscv-tools GitHub repository at https://github.com/riscv/riscv-tools. Note that because EBREAK only makes sense when gdb is running or while in FS mode, it is not included in the linux-rv64i insttest. ERET is not included because it does not make sense in SE mode and, in fact, causes a panic by design. Note also that not every system call is tested in linux-rv64i; of the ones defined in linux/process.hh, some have been given numbers but not definitions for the toolchain, or are merely stubs that always return 0. Of the ones that do work properly, only a subset are tested due to similar functionality. Signed-off by: Alec Roelke Signed-off by: Jason Lowe-Power <jason@lowepower.com>

All we need is the memory system, so there is really no need to compile the ISA over and over again.

Continue along the same line as the recent patch that made the Ruby-related config scripts Python packages and make also the configs/common directory a package. All affected config scripts are updated (hopefully). Note that this change makes it apparent that the current organisation and naming of the config directory and its subdirectories is rather chaotic. We mix scripts that are directly invoked with scripts that merely contain convenience functions. While it is not addressed in this patch we should follow up with a re-organisation of the config structure, and renaming of some of the packages.

2016-10-13ruby: Fix regressions and make Ruby configs Python packagesAndreas Hansson
This patch moves the addition of network options into the Ruby module to avoid the regressions all having to add it explicitly. Doing this exposes an issue in our current config system though, namely the fact that addtoPath is relative to the Python script being executed. Since both example and regression scripts use the Ruby module we would end up with two different (relative) paths being added. Instead we take a first step at turning the config modules into Python packages, simply by adding a __init__.py in the configs/ruby, configs/topologies and configs/network subdirectories. As a result, we can now add the top-level configs directory to the Python search path, and then use the package names in the various modules. The example scripts are also updated, and the messy path-deducing variations in the scripts are unified.

As a workaround, add a file named EMPTY to the list of ignored files in the test harness. This file can be used as a placeholder in otherwise empty test directories.

2016-06-20mem: Resolve TrafficGen trace relative to the configAndreas Sandberg
The traffic generator currently resolves relative trace paths relative to gem5's current working directory. This can lead to surprising results for relative paths where the expectation would normally be that they are resolved relative to the configuration file. This changeset implements config-relative trace file lookups. The old behavior is kept as a fallback for configs that expect that behavior.
