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. 9036:6385cf85bf12 Thu May 31 13:30:00 EDT 2012 Andreas Hansson <andreas.hansson@arm.com> Bus: Split the bus into a non-coherent and coherent bus This patch introduces a class hierarchy of buses, a non-coherent one, and a coherent one, splitting the existing bus functionality. By doing so it also enables further specialisation of the two types of buses. A non-coherent bus connects a number of non-snooping masters and slaves, and routes the request and response packets based on the address. The request packets issued by the master connected to a non-coherent bus could still snoop in caches attached to a coherent bus, as is the case with the I/O bus and memory bus in most system configurations. No snoops will, however, reach any master on the non-coherent bus itself. The non-coherent bus can be used as a template for modelling PCI, PCIe, and non-coherent AMBA and OCP buses, and is typically used for the I/O buses. A coherent bus connects a number of (potentially) snooping masters and slaves, and routes the request and response packets based on the address, and also forwards all requests to the snoopers and deals with the snoop responses. The coherent bus can be used as a template for modelling QPI, HyperTransport, ACE and coherent OCP buses, and is typically used for the L1-to-L2 buses and as the main system interconnect. The configuration scripts are updated to use a NoncoherentBus for all peripheral and I/O buses. A bit of minor tidying up has also been done. 8839:eeb293859255 Mon Feb 13 06:43:00 EST 2012 Andreas Hansson <andreas.hansson@arm.com> MEM: Introduce the master/slave port roles in the Python classes This patch classifies all ports in Python as either Master or Slave and enforces a binding of master to slave. Conceptually, a master (such as a CPU or DMA port) issues requests, and receives responses, and conversely, a slave (such as a memory or a PIO device) receives requests and sends back responses. Currently there is no differentiation between coherent and non-coherent masters and slaves. The classification as master/slave also involves splitting the dual role port of the bus into a master and slave port and updating all the system assembly scripts to use the appropriate port. Similarly, the interrupt devices have to have their int_port split into a master and slave port. The intdev and its children have minimal changes to facilitate the extra port. Note that this patch does not enforce any port typing in the C++ world, it merely ensures that the Python objects have a notion of the port roles and are connected in an appropriate manner. This check is carried when two ports are connected, e.g. bus.master = memory.port. The following patches will make use of the classifications and specialise the C++ ports into masters and slaves. |

However, by default these will check the file extention for .gz, and create a gzip compressed stream if the file ending matches. When writing out files, we want to write them out exactly as they are in the guest simulation, and never want to compress them with gzio. Additionally, this causes m5 writefile to fail when checking the error flags for the output steam. With this patch we add an additional no_gz argument to OutputDirectory::create and OutputDirectory::openFile which allows us to override the gzip compression. Therefore, for m5 writefile we disable the filename check, and always create a standard ostream. 9398:6a348f61220c Mon Jan 07 13:05:00 EST 2013 Andreas Hansson <andreas.hansson@arm.com> mem: Add tracing support in the communication monitor This patch adds packet tracing to the communication monitor using a protobuf as the mechanism for creating the trace.

H A D | remote_gdb.hh | 8931:7a1dfb191e3f Fri Apr 06 13:46:00 EDT 2012 Andreas Hansson <andreas.hansson@arm.com> MEM: Enable multiple distributed generalized memories This patch removes the assumption on having on single instance of PhysicalMemory, and enables a distributed memory where the individual memories in the system are each responsible for a single contiguous address range. All memories inherit from an AbstractMemory that encompasses the basic behaviuor of a random access memory, and provides untimed access methods. What was previously called PhysicalMemory is now SimpleMemory, and a subclass of AbstractMemory. All future types of memory controllers should inherit from AbstractMemory. To enable e.g. the atomic CPU and RubyPort to access the now distributed memory, the system has a wrapper class, called PhysicalMemory that is aware of all the memories in the system and their associated address ranges. This class thus acts as an infinitely-fast bus and performs address decoding for these "shortcut" accesses. Each memory can specify that it should not be part of the global address map (used e.g. by the functional memories by some testers). Moreover, each memory can be configured to be reported to the OS configuration table, useful for populating ATAG structures, and any potential ACPI tables. Checkpointing support currently assumes that all memories have the same size and organisation when creating and resuming from the checkpoint. A future patch will enable a more flexible re-organisation. 8229:78bf55f23338 Fri Apr 15 13:44:00 EDT 2011 Nathan Binkert <nate@binkert.org> includes: sort all includes 3571:ced6d2818217 Wed Nov 08 02:13:00 EST 2006 Gabe Black <gblack@eecs.umich.edu> Changed the getReg and setReg functions so that they work like netbsd.

H A D | InvalidateGenerator.cc | 8975:7f36d4436074 Tue May 01 13:40:00 EDT 2012 Andreas Hansson <andreas.hansson@arm.com> MEM: Separate requests and responses for timing accesses This patch moves send/recvTiming and send/recvTimingSnoop from the Port base class to the MasterPort and SlavePort, and also splits them into separate member functions for requests and responses: send/recvTimingReq, send/recvTimingResp, and send/recvTimingSnoopReq, send/recvTimingSnoopResp. A master port sends requests and receives responses, and also receives snoop requests and sends snoop responses. A slave port has the reciprocal behaviour as it receives requests and sends responses, and sends snoop requests and receives snoop responses. For all MemObjects that have only master ports or slave ports (but not both), e.g. a CPU, or a PIO device, this patch merely adds more clarity to what kind of access is taking place. For example, a CPU port used to call sendTiming, and will now call sendTimingReq. Similarly, a response previously came back through recvTiming, which is now recvTimingResp. For the modules that have both master and slave ports, e.g. the bus, the behaviour was previously relying on branches based on pkt->isRequest(), and this is now replaced with a direct call to the apprioriate member function depending on the type of access. Please note that send/recvRetry is still shared by all the timing accessors and remains in the Port base class for now (to maintain the current bus functionality and avoid changing the statistics of all regressions). The packet queue is split into a MasterPort and SlavePort version to facilitate the use of the new timing accessors. All uses of the PacketQueue are updated accordingly. With this patch, the type of packet (request or response) is now well defined for each type of access, and asserts on pkt->isRequest() and pkt->isResponse() are now moved to the appropriate send member functions. It is also worth noting that sendTimingSnoopReq no longer returns a boolean, as the semantics do not alow snoop requests to be rejected or stalled. All these assumptions are now excplicitly part of the port interface itself. 8232:b28d06a175be Fri Apr 15 13:44:00 EDT 2011 Nathan Binkert <nate@binkert.org> trace: reimplement the DTRACE function so it doesn't use a vector At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing.

These are IntReg, FloatReg, FloatRegBits, and MiscReg. These have been supplanted by the global types RegVal and FloatRegVal.

This basically just handles setting and getting the values of the interrupt-pending and interrupt-enable CSRs according to the privileged ISA reference chapter 3.1.14. Note that it does NOT implement the PLIC as defined in chapter 7, as that is used for handling external interrupts which are defined based on peripherals that are available.

Additionally, a new fault was implemented. It is executed once the CPU is initialized. This fault clears all interrupts and sets the pc to a reset vector.

In order to accommodate speculation with variable instruction widths, a few assertions in decoder had to be changed to returning faults as the specification describes should normally happen. The rest of these assertions will be changed in a later patch. [Remove commented-out debugging line and add clarifying comment to registerName in utility.hh.] Change-Id: I3f333008430d4a905cb59547a3513f5149b43b95 Reviewed-on: https://gem5-review.googlesource.com/4041 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Alec Roelke <ar4jc@virginia.edu> |
