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.

2006-03-03Changes to support automatic renaming of the shadow registers at decode ↵Kevin Lim
time. This requires using an ExtMachInst (uint64_t) instead of the normal MachInst; the ExtMachInst is packed with extra decode context information. In the case of Alpha, the PAL mode is included. The shadow registers are folded into the normal integer registers to ease renaming indexing. Include the removed Opcdec class of instructions for faulting when a pal mode only instruction is decoded in non-pal mode. arch/alpha/ev5.cc: Changes to automatically map the shadow registers if the instruction is in PAL mode. arch/alpha/isa/branch.isa: arch/alpha/isa/decoder.isa: arch/alpha/isa/fp.isa: arch/alpha/isa/int.isa: arch/alpha/isa/mem.isa: arch/alpha/isa/pal.isa: arch/alpha/isa/unimp.isa: Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits. arch/alpha/isa/main.isa: Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits. The decoder (for Alpha) uses the 32nd bit in order to determine if the machine is in PAL mode. If it is, then it refers to the reg_redir table to determine the true index of the register it is using. Also include the opcdec instruction definition. arch/alpha/isa_traits.hh: Define ExtMachInst type that is used by the static inst in order to decode the instruction, given the context of being in pal mode or not. Redefine the number of Int registers, splitting it into NumIntArchRegs (32) and NumIntRegs (32 + 8 shadow registers). Change the dependence tags to reflect the integer registers include the 8 shadow registers. Define function to make an ExtMachInst. Currently it is somewhat specific to Alpha; in the future it must be decided to make this more generic and possibly slower, or leave it specific to each architecture and ifdef it within the CPU. arch/isa_parser.py: Have static insts decode on the ExtMachInst. base/remote_gdb.cc: Support the automatic remapping of shadow registers. Remote GDB must now look at the PC being read in order to tell if it should use the normal register indices or the shadow register indices. cpu/o3/regfile.hh: Comment out the pal registers; they are now a part of the integer registers. cpu/simple/cpu.cc: Create an ExtMachInst to decode on, based on the normal MachInst and the PC of the instructoin. cpu/static_inst.hh: Change from MachInst to ExtMachInst to support shadow register renaming. --HG-- extra : convert_revision : 1d23eabf735e297068e1917445a6348e9f8c88d5

2006-02-27Changes to put all the misc regs within the misc reg file. This includes ↵Kevin Lim
the FPCR, Uniq, lock flag, lock addr, and IPRs. They are now accessed by calling readMiscReg()/setMiscReg() on the XC. Old IPR accesses are supported by using readMiscRegWithEffect() and setMiscRegWithEffect() (names may change in the future). arch/alpha/alpha_memory.cc: Change accesses to IPR to go through the XC. arch/alpha/ev5.cc: Change accesses for IPRs to go through the misc regs. arch/alpha/isa/decoder.isa: Change accesses to IPRs to go through the misc regs. readIpr() and setIpr() are now changed to calls to readMiscRegWithEffect() and setMiscRegWithEffect(). arch/alpha/isa/fp.isa: Change accesses to IPRs and Fpcr to go through the misc regs. arch/alpha/isa/main.isa: Add support for all misc regs being accessed through readMiscReg() and setMiscReg(). Instead of readUniq and readFpcr, they are replaced by calls with Uniq_DepTag and Fpcr_DepTag passed in as the register index. arch/alpha/isa_traits.hh: Change the MiscRegFile to a class that handles all accesses to MiscRegs, which in Alpha include the FPCR, Uniq, Lock Addr, Lock Flag, and IPRs. Two flavors of accesses are supported: normal register reads/writes, and reads/writes with effect. The latter are basically the original read/write IPR functions, while the former are normal reads/writes. The lock flag and lock addr registers are added to the dependence tags in order to support being accessed through the misc regs. arch/alpha/stacktrace.cc: cpu/simple/cpu.cc: dev/sinic.cc: Change accesses to the IPRs to go through the XC. arch/alpha/vtophys.cc: Change access to the IPR to go through the XC. arch/isa_parser.py: Change generation of code for control registers to use the readMiscReg and setMiscReg functions. base/remote_gdb.cc: Change accesses to the IPR to go through the XC. cpu/exec_context.hh: Use the miscRegs to access the lock addr, lock flag, and other misc registers. cpu/o3/alpha_cpu.hh: cpu/simple/cpu.hh: Support interface for reading and writing misc registers, which replaces readUniq, readFpcr, readIpr, and their set functions. cpu/o3/alpha_cpu_impl.hh: Change accesses to the IPRs to go through the miscRegs. For now comment out some of the accesses to the misc regs until the proxy exec context is completed. cpu/o3/alpha_dyn_inst.hh: Change accesses to misc regs to use readMiscReg and setMiscReg. cpu/o3/alpha_dyn_inst_impl.hh: Remove old misc reg accessors. cpu/o3/cpu.cc: Comment out old misc reg accesses until the proxy exec context is completed. cpu/o3/cpu.hh: Change accesses to the misc regs. cpu/o3/regfile.hh: Remove old access methods for the misc regs, replace them with readMiscReg and setMiscReg. They are dummy functions for now until the proxy exec context is completed. kern/kernel_stats.cc: kern/system_events.cc: Have accesses to the IPRs go through the XC. kern/tru64/tru64.hh: Have accesses to the misc regs use the new access methods. --HG-- extra : convert_revision : e32e0a3fe99522e17294bbe106ff5591cb1a9d76

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.
