2006-05-01move code from packet.hh to packet.cc and packet_impl.hhAli Saidi
fix very annoying not-compiler bug arch/sparc/regfile.hh: You have not included an out-of-class definition of your static members. See [9.4.2]/4 and about a billion gcc bug reports. If statements get around the problem through some magic, and than seems nicer that putting a definition of them in a c file somewhere. cpu/simple/cpu.cc: get() and set() do the conversion now dev/io_device.hh: need get() and set() defentions in all the devices mem/packet.cc: mem/packet.hh: move code from packet.hh to packet.cc mem/physical.cc: packet_impl needed for templated packet functions --HG-- extra : convert_revision : 6c11842aa928d9af7b4cabe826306fe1fe09e693

2006-04-07Move to a model with a unified request object.Ron Dreslinski
Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request. When accedding variables of a cpu_request it asserts that it is a cpu_request. It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read). There is also a isCpuReq() function to determine if this is a cpu_request. It should be called before accesing a cpu_request only variable.

Also explicitly load BSS now since we need to allocate the translations for it in syscall emulation. cpu/base.hh: Don't need memPort (just pass port in to ExecContext constructor). cpu/exec_context.cc: cpu/exec_context.hh: mem/port.cc: mem/translating_port.cc: mem/translating_port.hh: Pass syscall emulation Port into constructor instead of getting it from BaseCPU. cpu/simple/cpu.cc: Explicitly choose one of three timing models. Statically allocate request and packet objects when possible. Several more minor bug fixes. Works for simple program with SIMPLE_CPU_MEM_IMMEDIATE model now. Probably have memory leaks with SIMPLE_CPU_MEM_TIMING (if it works at all). Pass syscall emulation Port into constructor instead of getting it from BaseCPU. cpu/simple/cpu.hh: Explicitly choose one of three timing models. Statically allocate request and packet objects when possible. Pass syscall emulation Port into constructor instead of getting it from BaseCPU. mem/physical.cc: Set packet result field. --HG-- extra : convert_revision : 359d0ebe4b4665867f4e26e7394ec0f1d17cfc26
2006-03-02More progress... run a few instructions now, but die on the secondSteve Reinhardt
memory access (I think because we're deallocating our one and only CpuRequest object). base/loader/aout_object.cc: base/loader/ecoff_object.cc: base/loader/elf_object.cc: Add flag to force allocation of new pages on data writes. cpu/simple/cpu.cc: Several minor fixes. Switch to atomic mode for now. mem/physical.hh: Don't copy the packet to the response event, just keep a reference to the original. mem/translating_port.cc: mem/translating_port.hh: Add parameter to writeBlobFunctional() to force allocation of unallocated pages on writes. --HG-- extra : convert_revision : 05cb31c7b0047b492dcfa0d12ddee690ef762b44
2006-03-01More progress toward actually running a program.Steve Reinhardt
See configs/test.py for test config (using simple binary in my home directory on zizzer). base/chunk_generator.hh: Fix assertion for chunkSize == 0 (not a power of 2) base/intmath.hh: Fix roundDown to take integer alignments. cpu/base.cc: Register exec contexts regardless of state (not sure why this check was in here in the first place). mem/physical.cc: Add breaks to switch. python/m5/objects/BaseCPU.py: Default mem to Parent.any (e.g. get from System). python/m5/objects/Ethernet.py: python/m5/objects/Root.py: HierParams is gone. python/m5/objects/PhysicalMemory.py: mmu param is full-system only. sim/process.cc: Stack mapping request must be page-aligned and page-sized. Don't delete objFile object in create since we are counting on it being around for startup(). --HG-- extra : convert_revision : 90c43ee927e7d82a045d6e10302d965797d006f7

2006-02-23Add support for multiple ports on the memory. Hook up simple cpu to memory.Ron Dreslinski
Ready to start testing if I could fix the linking errors I can't ever seem to fix. cpu/simple/cpu.cc: cpu/simple/cpu.hh: Add connecting of ports until builder can handle it. mem/physical.cc: Add function to allocate a port in the object Remove some full_sys stuff untill needed mem/physical.hh: Add function to allocate a port in the object python/m5/objects/BaseCPU.py: Update the params sim/process.cc: Make sure to use the right name (hopefully CPU constructor already called) --HG-- extra : convert_revision : 4089caf20d7eb53e5463c8ac93ddce5e43ea5d85
2006-02-23Update functional memory to have a response eventRon Dreslinski
Clean out old memory python files, move them into old_mem directory. Maybe we should just delete them, they are under revision control. Add new py files for new objects. SConscript: Update because memory is just a header file now base/chunk_generator.hh: Make Chunk Generator return the entire size if the chunk_size is set to zero. Useful when trying to chunck on blocksize of memory, which can write large pieces of data. cpu/simple/cpu.cc: Make sure to delete the pkt. mem/physical.cc: mem/physical.hh: Set up response event. mem/port.cc: Rename rqst to req to conform to same standard naming convention. python/m5/objects/PhysicalMemory.py: Update the params, inheritence --HG-- extra : convert_revision : 857154ec256522baf423b715833930497999549b

2006-02-22Move the port from base memory object into the physical memory object.Ron Dreslinski
The Memory is now a pure virtual base class for all memory type objects (DRAM, physical). We should consider renaming MemObject to something more meaningful to represent it is for all memory heirarchy objects, perhaps MemHeirObject? mem/physical.cc: mem/physical.hh: Move the port from the base class into the actual object. --HG-- extra : convert_revision : b7754ee7b90fd8f816f9876dce374c1d43c7e34b
2006-02-21Some more changes for compilation. Since memset is now part of port and not ↵Ron Dreslinski
virtual, no need for memory to define them. mem/physical.cc: Return 0 for block size. The chunk generator should treat this as a infinite size. mem/physical.hh: Add function prototype mem/port.hh: Fix function to take no arguments mem/translating_port.cc: mem/translating_port.hh: Remove the memsetBlob because it doesn't exist yet. --HG-- extra : convert_revision : dfe352acfc2912ecc9a1ba1863e5666f46b991cc
2006-02-21Add blocksize functions to physical memory. Fix the port we were using in ↵Ron Dreslinski
the process loader. mem/physical.cc: Implement the blockSize function, return VMPageSize for the physical memory mem/port.hh: Add a function to get a pointer to a peer, needed for initVirtMem to work in the loader. sim/process.cc: The way the translating port is setup we don't want the memory port, we want the peer port associated with that memory. We may need to revisit this. --HG-- extra : convert_revision : 46a51d448d1683db7bd5afe64adbe167a5743060

functions, the send/recv*Query naming seems awkward. Also create a typedef for AddrRangeList. --HG-- extra : convert_revision : dd0ff3fad06ec329c82c199700d0a6264f1271d3

sendBlockSizeQuery() -> peerBlockSize() recvBlockSizeQuery() -> deviceBlockSize() After seeing how this gets used in practice, the send/recv*Query names just don't make a lot of sense. dev/io_device.cc: mem/port.cc: sendBlockSizeQuery() -> peerBlockSize() mem/port.hh: sendBlockSizeQuery() -> peerBlockSize() recvBlockSizeQuery() -> deviceBlockSize() --HG-- extra : convert_revision : e96349fb443979b85899a5248bd7cd8665e23ef0

clean up implementation a little. SConscript: Add mem/port.cc cpu/simple/cpu.cc: cpu/simple/cpu.hh: Move read/writeBlob functions to base Port class. mem/port.hh: Implement read/writeBlob functions. No need for them to be virtual since the proxy object (now called TranslatingPort) is not a subclass of Port. mem/port.cc: Implement read/writeBlob functions. --HG-- extra : convert_revision : a3660eaa43a7c286aca962f17fa32fbd42bf1fa6
2006-02-21Thanks to Ali, I was able to add chunk generation code in to handle a few ↵Ron Dreslinski
cases. Still have some duplicated code we may want to revisit. cpu/simple/cpu.cc: Thanks to Ali I found the chunk generator, although I still seem to be duplicating some code becuase the only difference between readBlob and writeBlob is the command in the packet. Perhaps an access function with the command as a param would help with the duplication (sendBlob that takes a cmd (maybe). mem/translating_port.cc: Using the chunck generator to break it up to be in page size chunks --HG-- extra : convert_revision : cc2e4e60c76098655e469f81c89d2c7438350fdb
