2017-11-08dev: Move generic serial devices to src/dev/serialAndreas Sandberg
Change-Id: I104227fc460f8b561e7375b329a541c1fce881b2 Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com> Reviewed-on: https://gem5-review.googlesource.com/4291 Reviewed-by: Gabe Black <gabeblack@google.com>
2017-11-08dev: Refactor UART->Terminal interfaceAndreas Sandberg
The UART models currently assume that they are always wired to a terminal. While true at the moment, this isn't necessarily a valid assumption. This change introduces the SerialDevice class that defines the interface for serial devices. Currently, Terminal is the only class that implements this interface.

2015-11-27base: Add support for changing output directoriesAndreas Sandberg
This changeset adds support for changing the simulator output directory. This can be useful when the simulation goes through several stages (e.g., a warming phase, a simulation phase, and a verification phase) since it allows the output from each stage to be located in a different directory. Relocation is done by calling core.setOutputDir() from Python or simout.setOutputDirectory() from C++. This change affects several parts of the design of the gem5's output subsystem. First, files returned by an OutputDirectory instance (e.g., simout) are of the type OutputStream instead of a std::ostream. This allows us to do some more book keeping and control re-opening of files when the output directory is changed. Second, new subdirectories are OutputDirectory instances, which should be used to create files in that sub-directory.

2015-08-07base: Rewrite the CircleBuf to fix bugs and add serializationAndreas Sandberg
The CircleBuf class has at least one bug causing it to overwrite the wrong elements when wrapping. The current code has a lot of unused functionality and duplicated code. This changeset replaces the old implementation with a new version that supports serialization and arbitrary types in the buffer (not just char).
2014-09-20dev: Refactor terminal<->UART interface to make it more genericAndreas Sandberg
The terminal currently assumes that the transport to the guest always inherits from the Uart class. This assumption breaks when implementing, for example, a VirtIO consoles. This patch removes this assumption by adding pointer to the from the terminal to the uart and replacing it with a more general callback interface. The Uart, or any other class using the terminal, class implements an instance of the callbacks class and registers it with the terminal.
