2006-03-07Some clean up work with faults.Gabe Black
arch/alpha/faults.cc: Renamed the _stat stat to a more descriptive _count, got rid of some old commented out code, and moved common fault handling code, ie recording that the fault happend and that it wasn't mispeculated, into the FaultBase class. arch/alpha/faults.hh: Renamed the _stat stat to the more descriptive _count, and renamed the appropriate accessor functions. kern/kernel_stats.cc: kern/kernel_stats.hh: The fault statistics are now handled by the fault classes themselves. sim/faults.cc: The default implementation of the "invoke" method now does what all faults should do first, ie record that the fault happened, and make sure the fault isn't being executed on a mispeculated execution path. sim/faults.hh: There is now a default implementation of invoke, and the stat function is taken care of in the architecture specific fault classes. --HG-- extra : convert_revision : f6656fbea991df9addf85cad740ac37b1036b71a
2006-03-01Got rid of the multiple inheritance in the Fault classes, and the base ↵Gabe Black
MachineCheck and Alignment faults. --HG-- extra : convert_revision : 4b1429ef5c7a11c25e28f2bc868cc1481a08c5d1
2006-03-01Cleaned up some of the Fault system.Gabe Black
arch/alpha/ev5.cc: Commented out the intr_post function since it's not used. If this really -is- needed, it should be moved into the fault class. arch/alpha/faults.cc: arch/alpha/faults.hh: Moved the fault invocation code into the fault class fully, and got rid of the need for isA. cpu/exec_context.cc: cpu/exec_context.hh: Removed the trap function from the ExecContext. The faults will execute normally in full system mode, but always panic in syscall emulation mode. cpu/ozone/cpu.hh: cpu/simple/cpu.hh: Changed the execution context executing a fault to a fault executing on the execution context. sim/faults.cc: If not in full system mode, trying to invoke a fault causes a panic. sim/faults.hh: Removed the isA function. --HG-- extra : convert_revision : 894dc8f0755c8efc4b7ef5a09fb2cf7373042395

specific classes to prevent instantiation of the generic classes. --HG-- extra : convert_revision : 0378261342df008c2bf6d260295ef21b15f119a8
2006-02-24Changed Fault from a FaultBase * to a RefCountingPtr, added "new"s where ↵Gabe Black
appropriate, and took away the constant examples of each fault which where for comparing to a fault to determine its type. arch/alpha/alpha_memory.cc: arch/alpha/isa/decoder.isa: Added news where faults are created. arch/alpha/ev5.cc: Changed places where a fault was compared to a fault type to use isA rather than == arch/alpha/faults.cc: arch/alpha/faults.hh: Changed Fault to be a RefCountingPtr arch/alpha/isa/fp.isa: Added a new where a FloatEnableFault was created. arch/alpha/isa/unimp.isa: arch/alpha/isa/unknown.isa: Added a new where an UnimplementedFault is created. base/refcnt.hh: Added include of stddef.h for the NULL macro cpu/base_dyn_inst.cc: Added a new where an UnimplementedOpcodeFault is created. cpu/o3/alpha_cpu_impl.hh: Changed places where a fault was compared to a fault type to use isA rather than ==. Also changed fault->name to fault->name() cpu/o3/regfile.hh: Added new where UnimplementedOpcodeFaults are created. cpu/simple/cpu.cc: Changed places where a fault was compared to a fault type to use isA rather than ==. Also added a new where an Interrupt fault is created. dev/alpha_console.cc: Added news where MachineCheckFaults are created. dev/pcidev.hh: Added news where MachineCheckFaults are generated. dev/sinic.cc: Changed places where a fault was compared to a fault type to use isA rather than ==. Added news where MachineCheckFaults are created. Fixed a problem where m5.fast had unused variables. kern/kernel_stats.cc: Commented out where _faults is initialized. This statistic will probably be moved elsewhere in the future. kern/kernel_stats.hh: Commented out the declaration of _fault. when fault() is called, the fault increments its own stat. sim/faults.cc: sim/faults.hh: Changed Fault from a FaultBase * to a RefCountingPtr. --HG-- extra : convert_revision : b40ccfc42482d5a115e111dd897fa378d23c6c7d
2006-02-16Remove fake fault.Kevin Lim
Switch fault pointers to const pointers to prevent them from accidentally being changed. Fix some coding style. arch/alpha/ev5.cc: cpu/o3/commit_impl.hh: kern/kernel_stats.hh: Remove fake fault. arch/alpha/faults.cc: Remove fake fault, fix to have normal m5 line length limit, and change pointers to be const pointers so that the default faults aren't changed accidentally. arch/alpha/faults.hh: Fix to have normal m5 line length limit, change pointers to const pointers. sim/faults.cc: sim/faults.hh: Remove fake fault, change pointers to const pointers. --HG-- extra : convert_revision : 01d4600e0d4bdc1d177b32edebc78f86a1bbfe2e
2006-02-16Changed the fault enum into a class, and fixed everything up to work with ↵Gabe Black
it. Next, the faults need to be pulled out of all the other code so that they are only used to communicate between the CPU and the ISA. SConscript: The new faults.cc file in sim allocates the system wide faults. When these faults are generated through a function interface in the ISA, this file may go away. arch/alpha/alpha_memory.cc: Changed Fault to Fault * and took the underscores out of fault names. arch/alpha/alpha_memory.hh: Changed Fault to Fault *. Also, added an include for the alpha faults. arch/alpha/ev5.cc: Changed the fault_addr array into a fault_addr function. Once all of the faults can be expected to have the same type, fault_addr can go away completely and the info it provided will come from the fault itself. Also, Fault was changed to Fault *, and underscores were taken out of fault names. arch/alpha/isa/decoder.isa: Changed Fault to Fault * and took the underscores out fault names. arch/alpha/isa/fp.isa: Changed Fault to Fault *, and took the underscores out of fault names. arch/alpha/isa/main.isa: Changed Fault to Fault *, removed underscores from fault names, and made an include of the alpha faults show up in all the generated files. arch/alpha/isa/mem.isa: Changed Fault to Fault * and removed underscores from fault names. arch/alpha/isa/unimp.isa: arch/alpha/isa/unknown.isa: cpu/exec_context.hh: cpu/ozone/cpu.hh: cpu/simple/cpu.cc: dev/alpha_console.cc: dev/ide_ctrl.cc: dev/isa_fake.cc: dev/pciconfigall.cc: dev/pcidev.cc: dev/pcidev.hh: dev/tsunami_cchip.cc: dev/tsunami_io.cc: dev/tsunami_pchip.cc: Changed Fault to Fault *, and removed underscores from fault names. arch/alpha/isa_traits.hh: Changed the include of arch/alpha/faults.hh to sim/faults.hh, since the alpha faults weren't needed. cpu/base_dyn_inst.cc: Changed Fault to Fault *, and removed underscores from fault names. This file probably shouldn't use the Unimplemented Opcode fault. cpu/base_dyn_inst.hh: Changed Fault to Fault * and took the underscores out of the fault names. cpu/exec_context.cc: cpu/o3/alpha_dyn_inst.hh: cpu/o3/alpha_dyn_inst_impl.hh: cpu/o3/fetch.hh: dev/alpha_console.hh: dev/baddev.hh: dev/ide_ctrl.hh: dev/isa_fake.hh: dev/ns_gige.hh: dev/pciconfigall.hh: dev/sinic.hh: dev/tsunami_cchip.hh: dev/tsunami_io.hh: dev/tsunami_pchip.hh: dev/uart.hh: dev/uart8250.hh: Changed Fault to Fault *. cpu/o3/alpha_cpu.hh: Changed Fault to Fault *, removed underscores from fault names. cpu/o3/alpha_cpu_impl.hh: Changed Fault to Fault *, removed underscores from fault names, and changed the fault_addr array to the fault_addr function. Once all faults are from the ISA, this function will probably go away. cpu/o3/commit_impl.hh: cpu/o3/fetch_impl.hh: dev/baddev.cc: Changed Fault to Fault *, and removed underscores from the fault names. cpu/o3/regfile.hh: Added an include for the alpha specific faults which will hopefully go away once the ipr stuff is moved, changed Fault to Fault *, and removed the underscores from fault names. cpu/simple/cpu.hh: Changed Fault to Fault * dev/ns_gige.cc: Changed Fault to Fault *, and removdd underscores from fault names. dev/sinic.cc: Changed Fault to Fault *, and removed the underscores from fault names. dev/uart8250.cc: Chanted Fault to Fault *, and removed underscores from fault names. kern/kernel_stats.cc: Removed underscores from fault names, and from NumFaults. kern/kernel_stats.hh: Changed the predeclaration of Fault from an enum to a class, and changd the "fault" function to work with the classes instead of the enum. Once there are no system wide faults anymore, this code will simplify back to something like it was originally. sim/faults.cc: This allocates the system wide faults. sim/faults.hh: This declares the system wide faults. sim/syscall_emul.cc: sim/syscall_emul.hh: Removed the underscores from fault names. --HG-- rename : arch/alpha/faults.cc => sim/faults.cc rename : arch/alpha/faults.hh => sim/faults.hh extra : convert_revision : 253d39258237333ae8ec4d8047367cb3ea68569d
