2010-11-19SE: Fix simulating more than 4GB of RAM in SE modeAli Saidi
This change removes some dead code in PhysicalMemory, uses a 64 bit type for the page pointer in System (instead of 32 bit) and cleans up some style.
2010-11-08ARM: Add checkpointing supportAli Saidi
2010-11-08Mem: Finish half-baked support for mmaping file in physmem.Ali Saidi
Physmem has a parameter to be able to mem map a file, however it isn't actually used. This changeset utilizes the parameter so a file can be mmapped.
2010-01-19util: do checkpoint aggregation more cleanly, fix last changeset.Lisa Hsu
1) Move alpha-specific code out of page_table.cc:serialize(). 2) Begin serializing M5_pid and unserializing it, but adding an function to do optional paramIn so that old checkpoints don't need to be fixed up. 3) Fix up alpha startup code so that the unserialized M5_pid value is properly written to DTB_IPR_ASN. 4) Fix the memory unserialize that I forgot somehow in the last changeset. 5) Add in an agg_se.py to handle aggregated checkpoints. --bench foo-bar plus positional arguments foo bar are the only changes in usage from se.py. Note this aggregation stuff has only been tested for Alpha and nothing else, though it should take a very minimal amount of work to get it to work with another ISA.

2009-08-01Fix setting of INST_FETCH flag for O3 CPU.Steve Reinhardt
It's still broken in inorder. Also enhance DPRINTFs in cache and physical memory so we can see more easily whether it's getting set or not.
2009-07-08Registers: Add a registers.hh file as an ISA switched header.Gabe Black

2009-04-19Memory: Rename LOCKED for load locked store conditional to LLSC.Gabe Black
2008-11-02Add in Context IDs to the simulator. From now on, cpuId is almost never used,Lisa Hsu
the primary identifier for a hardware context should be contextId(). The concept of threads within a CPU remains, in the form of threadId() because sometimes you need to know which context within a cpu to manipulate.
2008-10-09eventq: convert all usage of events to use the new API.Nathan Binkert
For now, there is still a single global event queue, but this is necessary for making the steps towards a parallelized m5.
