2006-05-23Add extra flags to help new CPU handle various instructions.Kevin Lim
IsIprAccess flag may go away in the future (op class can be used to tell this), and the CPU still needs a specific way to identify/deal with syscalls. arch/alpha/isa/decoder.isa: Added a few extra flags to help the new CPU identify various classes of instructions without having to force certain behaviors for all CPUs. cpu/base_dyn_inst.hh: cpu/static_inst.hh: Added extra flags. cpu/o3/iew_impl.hh: cpu/o3/inst_queue_impl.hh: Handle store conditionals specially. cpu/o3/lsq_unit_impl.hh: Extra flags tells if the instruction is a store conditional. cpu/o3/rename_impl.hh: Handle IPR accesses and store conditionals specially. --HG-- extra : convert_revision : 39debec4fa5341ae8a8ab5650bd12730aeb6c04f

2006-05-16Add some flags for the upcoming checker.Kevin Lim
arch/alpha/isa/decoder.isa: Mark store conditionals as serializing. This is slightly higher over head than they truly have in the 264, but it's close. Normally they block any other instructions from entering the IQ until the IQ is empty. This is higher overhead because it waits until the ROB is empty. Also mark RPCC as unverifiable. The checker will just grab the value from the instruction and assume it's correct. cpu/static_inst.hh: Add unverifiable flag, specifically for the CheckerCPU. --HG-- extra : convert_revision : cbc34d1f2f5b07105d31d4bd8f19edae2cf8158e

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. SConscript: Include new file, cpu_exec_context.cc. arch/alpha/alpha_linux_process.cc: arch/alpha/alpha_memory.cc: arch/alpha/alpha_tru64_process.cc: arch/alpha/arguments.cc: arch/alpha/isa/decoder.isa: arch/alpha/stacktrace.cc: arch/alpha/vtophys.cc: base/remote_gdb.cc: cpu/intr_control.cc: Avoid directly accessing objects within the XC. arch/alpha/ev5.cc: Avoid directly accessing objects within the XC. KernelStats have been moved to the BaseCPU instead of the XC. arch/alpha/isa_traits.hh: Remove clearIprs(). It wasn't used very often and it did not work well with the proxy ExecContext. cpu/base.cc: Place kernel stats within the BaseCPU instead of the ExecContext. For now comment out the profiling code sampling until its exact location is decided upon. cpu/base.hh: Kernel stats are now in the BaseCPU instead of the ExecContext. cpu/base_dyn_inst.cc: cpu/base_dyn_inst.hh: cpu/memtest/memtest.cc: cpu/memtest/memtest.hh: Changes to support rename of old ExecContext to CPUExecContext. See changeset for more details. cpu/exetrace.cc: Remove unneeded include of exec_context.hh. cpu/intr_control.hh: cpu/o3/alpha_cpu_builder.cc: Remove unneeded include of exec_context.hh cpu/o3/alpha_cpu.hh: cpu/o3/alpha_cpu_impl.hh: cpu/o3/cpu.cc: cpu/o3/cpu.hh: cpu/simple/cpu.cc: cpu/simple/cpu.hh: Changes to support rename of old ExecContext to CPUExecContext.

Also kernel stats are now in the BaseCPU. sim/process.cc: sim/process.hh: Avoid accessing regs directly within an ExecContext. Instead use a CPUExecContext to initialize the registers and copy them over. cpu/cpu_exec_context.cc: Rename old ExecContext to CPUExecContext. This is used by the old CPU models to store any necessary architectural state. Also include the ProxyExecContext, which is used to access the CPUExecContext's state in code outside of the CPU. cpu/cpu_exec_context.hh: Rename old ExecContext to CPUExecContext. This is used by the old CPU models to store any necessary architectural state. Also include the ProxyExecContext, which is used to access the CPUExecContext's state in code outside of the CPU. Remove kernel stats from the ExecContext. sim/pseudo_inst.cc: Kernel stats now live within the CPU. Avoid accessing objects directly within the XC. --HG-- rename : cpu/exec_context.cc => cpu/cpu_exec_context.cc rename : cpu/exec_context.hh => cpu/cpu_exec_context.hh extra : convert_revision : a75393a8945c80cca225b5e9d9c22a16609efb85
