2012-08-21Clock: Move the clock and related functions to ClockedObjectAndreas Hansson
This patch moves the clock of the CPU, bus, and numerous devices to the new class ClockedObject, that sits in between the SimObject and MemObject in the class hierarchy. Although there are currently a fair amount of MemObjects that do not make use of the clock, they potentially should do so, e.g. the caches should at some point have the same clock as the CPU, potentially with a 1:n ratio. This patch does not introduce any new clock objects or object hierarchies (clusters, clock domains etc), but is still a step in the direction of having a more structured approach clock domains. The most contentious part of this patch is the serialisation of clocks that some of the modules (but not all) did previously. This serialisation should not be needed as the clock is set through the parameters even when restoring from the checkpoint. In other words, the state is "stored" in the Python code that creates the modules. The nextCycle methods are also simplified and the clock phase parameter of the CPU is removed (this could be part of a clock object once they are introduced).
2012-08-15O3,ARM: fix some problems with drain/switchout functionality and add Drain ↵Anthony Gutierrez
DPRINTFs This patch fixes some problems with the drain/switchout functionality for the O3 cpu and for the ARM ISA and adds some useful debug print statements. This is an incremental fix as there are still a few bugs/mem leaks with the switchout code. Particularly when switching from an O3CPU to a TimingSimpleCPU. However, when switching from O3 to O3 cores with the ARM ISA I haven't encountered any more assertion failures; now the kernel will typically panic inside of simulation.
2012-07-09Fix: Address a few benign memory leaksAndreas Hansson
This patch is the result of static analysis identifying a number of memory leaks. The leaks are all benign as they are a result of not deallocating memory in the desctructor. The fix still has value as it removes false positives in the static analysis.
2012-05-10IGbE: Fix writeback conditions for i8254x GbE in updated data sheet.Pritha Ghoshal
An older revision of the data sheet specified that txdctl.gran was 1 the granularity was based on cache block and gran being 0 is based on descriptor count. The newer version of the data sheet reverses this errata
2012-02-24MEM: Move port creation to the memory object(s) constructionAndreas Hansson
This patch moves all port creation from the getPort method to be consistently done in the MemObject's constructor. This is possible thanks to the Swig interface passing the length of the vector ports. Previously there was a mix of: 1) creating the ports as members (at object construction time) and using getPort for the name resolution, or 2) dynamically creating the ports in the getPort call. This is now uniform. Furthermore, objects that would not be complete without a port have these ports as members rather than having pointers to dynamically allocated ports. This patch also enables an elaboration-time enumeration of all the ports in the system which can be used to determine the masterId.

2011-09-13IGbE: Clean up debug printing and proprly account for copied bytes.Ali Saidi
Some DPRINTFs were printing uninitalized values because the DPRINTFs were always being printed even when the features they were printing weren't being used. This change moves the DPRINTFs into the appropriate if blocks and initializes the state variables correctly. There also is a case where the offset into the packet could be calculated incorrectly during a DMA that is fixed.
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help

This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
