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. SConscript: Add compilation support for request.cc arch/alpha/tlb.cc: arch/alpha/tlb.hh: cpu/cpu_exec_context.hh: cpu/exec_context.hh: cpu/simple/cpu.cc: cpu/simple/cpu.hh: dev/io_device.cc: mem/page_table.cc: mem/page_table.hh: mem/port.cc: Update for unified request object and accessor functions. mem/request.hh: Remove CpuRequest, make it a unified object. Make variables private with accessor functions. May want to move things from .cc file into header (usually a assert() and either returning a value, or writting two). --HG-- extra : convert_revision : f1e45cc490dadc7a418634539b03c3e72684a6e3

2006-04-06Enable register windows.Gabe Black
arch/alpha/isa_traits.hh: arch/mips/isa_traits.cc: Turned the integer register file into a class instead of a typedef to an array. arch/alpha/regfile.hh: Changed the integer register file into a class instead of a typedef to an array. Also put the parts of the register file, ie the int, float, and misc register files, pc, npc, and nnpc, behind accessor functions. Added a changeContext function, and ContextParam and ContextVal types, so that things like the register window can be changed through call backs. arch/mips/isa_traits.hh: Turned the integer register file into a class instead of a typedef to an array. Also moved a "using namespace" into the namespace definition. arch/sparc/isa_traits.hh: Turned the integer register file into a class instead of a typedef to an array. Also "fixed" the max number of src and dest regs. They may need to be even larger. arch/sparc/regfile.hh: Changed the integer register file into a class instead of a typedef to an array. Also put the parts of the register file, ie the int, float, and misc register files, pc, npc, and nnpc, behind accessor functions. Added a changeContext function, and ContextParam and ContextVal types, so that things like the register window can be changed through call backs. Created setCWP and setAltGlobals functions for the IntRegFile. cpu/cpu_exec_context.hh: Used the accessor functions for the register file, and added a changeRegFileContext function to call back into the RegFile. Used the RegFile clear function rather than memsetting it to 0. cpu/exec_context.hh: Added the changeRegFileContext function. cpu/exetrace.cc: Use the TheISA::NumIntRegs constant, and use readReg now that the integer register file is a class instead of an array. cpu/exetrace.hh: Get the address of the regs object, now that it isn't an array. --HG-- extra : convert_revision : ea2dd81be1c2e66b3c684af319eb58f8a77fd49c

2006-03-04Steps towards setting up the infrastructure to allow the new CPU model to ↵Kevin Lim
work in full system mode. The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext). Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC). The CPU uses the CPUExecContext, or however else it stores its own state. It then creates a ProxyExecContext, templated on the class used to hold its state. This proxy is passed to any code outside of the CPU that needs to access the XC. This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out. Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers.
