2011-10-30System: Push boot_cpu_frequency down into the subclasses that actually use it.Gabe Black
This parameter depends on a number of coincidences to work properly. First, there must be an array assigned to system called "cpu" even though there's no parameter called that. Second, the items in the "cpu" array have to have a "clock" parameter which has a "frequency" member. This is true of the normal CPUs, but isn't true of the memory tester CPUs. This happened to work before because the memory tester CPUs were only used in SE mode where this parameter was being excluded. Since everything is being pulled into a common binary, this won't work any more. Since the boot_cpu_frequency parameter is only used by Alpha's Linux System object (and Mips's through copy and paste), the definition of that parameter is moved down to those objects specifically.

2011-10-09[mq]: sefssparcregfile.patchGabe Black
2011-10-09Interrupts: Make the IO APIC go get the local APICs.Gabe Black
This is so they don't have to declare themselves to the IO APIC and don't have to have a pointer to the platform object.
2011-10-09SE/FS: Build the Interrupt objects in SE mode.Gabe Black
2011-10-04SE/FS: Put platform pointers in fewer objects.Gabe Black
Not all objects need a platform pointer, and having one creates a dependence on their being a platform object. This change removes the platform pointer to from the base device object and moves it into subclasses that actually need it.
2011-09-30SE/FS: Remove System::platform and Platform::intrFrequency.Gabe Black
In order for a system object to work in SE mode and FS mode, it has to either always require a platform object even in SE mode, or get rid of the requirement all together. Making SE mode carry around unnecessary/unused bits of FS seems less than ideal, so I decided to go with the second option. The platform pointer in the System class was used for exactly one purpose, a path for the Alpha Linux system object to get to the real time clock and read its frequency so that it could short cut the loops_per_jiffy calculation. There was also a copy and pasted implementation in MIPS, but since it was only there because it was there in Alpha I still count that as one use. This change reverses the mechanism that communicates the RTC frequency so that the Tsunami platform object pushes it up to the AlphaSystem object. This is slightly less specific than it could be because really only the AlphaLinuxSystem uses it. Because the intrFrequency function on the Platform class was no longer necessary (and unimplemented on anything but Alpha) it was eliminated. After this change, a platform will need to have a system, but a system won't have to have a platform.
2011-09-30X86: Remove FULL_SYSTEM from the x86 faults.Gabe Black
2011-09-30SE/FS: Build the devices in SE mode.Gabe Black
2011-09-30SE/FS: Use the new FullSystem constant where possible.Gabe Black
2011-09-27Faults: Replace calls to genMachineCheckFault with M5PanicFault.Gabe Black
2011-09-27Faults: Add in generic faults that work like panics, warns, etc.Gabe Black
These faults take varargs to their constructors which they print into a string and pass to the M5DebugFault base class. They are basically faults wrapped around panics, faults, warns, and warnonce-es so that they happen only at commit.
2011-09-26ISA parser: Use '_' instead of '.' to delimit type modifiers on operands.Gabe Black
By using an underscore, the "." is still available and can unambiguously be used to refer to members of a structure if an operand is a structure, class, etc. This change mostly just replaces the appropriate "."s with "_"s, but there were also a few places where the ISA descriptions where handling the extensions themselves and had their own regular expressions to update. The regular expressions in the isa parser were updated as well. It also now looks for one of the defined type extensions specifically after connecting "_" where before it would look for any sequence of characters after a "." following an operand name and try to use it as the extension. This helps to disambiguate cases where a "_" may legitimately be part of an operand name but not separate the name from the type suffix. Because leaving the "_" and suffix on the variable name still leaves a valid C++ identifier and all extensions need to be consistent in a given context, I considered leaving them on as a breadcrumb that would show what the intended type was for that operand. Unfortunately the operands can be referred to in code templates, the Mem operand in particular, and since the exact type of Mem can be different for different uses of the same template, that broke things.
2011-09-24SCons: Add a comment I forgot to add in earlier.Gabe Black
This comment was supposed to be added to an earlier change as part of review feedback, but I accidentally left it out when I pushed. Add it in now.
2011-09-24SCons: Make the ISA parser a source for its output files like the comments say.Gabe Black
There was a change a while ago that refactored some scons stuff which got rid of cpu_models.py but also accidentally got rid of the ISA parser as a source for its target files. That meant that changes which affected the parser wouldn't cause a rebuild unless they also changed one of the description files. This change fixes that.
2011-09-23X86: Move the MSR lookup table out of the TLB and into its own file.Gabe Black
Translating MSR addresses into MSR register indices took a lot of space in the TLB source and made looking around in that file awkward. This change moves the lookup into its own file to get it out of the way. It also changes it from a switch statement to a hash map which should hopefully be a little more efficient.
2011-09-19MIPS: Final overhaul of MIPS faults to kill #if FULL_SYSTEMGabe Black
This change is a significant reorganization of the MIPS fault code that gets rid of duplication, fixes some bugs, doubtlessly introduces others, and adds names for the exception code constants.
2011-09-19MIPS, faults: Update how the PC is set.Gabe Black
2011-09-19MIPS: Get rid of skipFaultInstruction and setRestartAddress.Gabe Black
Neither of these functions were used.
2011-09-19MIPS: Use inheritance to consolidate class definitions.Gabe Black
2011-09-19MIPS: Always compile in setExceptionState, including in SE mode.Gabe Black
Also fix the newly exposed and preexisting compile errors. This code hasn't been exposed in a while, and it's not up to date with the rest of gem5.
2011-09-19MIPS: Consolidate TLB related faults.Gabe Black
Pass in a bool to indicate if the fault is from a store instead of having two different classes. The classes were also misleadingly named since loads are also processed by the DTB but should return ITB faults since they aren't stores. The TLB may be returning the wrong fault in this case, but I haven't looked at it closely.
2011-09-19MIPS: Get rid of the unused "count" field in FaultVals.Gabe Black
2011-09-19MIPS: Move the genMachineCheckFault function near MachineCheckFault.Gabe Black
Since they're so closely linked, they should be next to each other in the file.
2011-09-19MIPS: Consolidate the two AddressErrorFault variants.Gabe Black
2011-09-19Faults: Get rid of the unused isAlignmentFault and isMachineCheckFault.Gabe Black
These functions aren't called anywhere and are probably only theoretically useful.
2011-09-19MIPS: Get rid of cruft in the fault classes.Gabe Black
Get rid of Fault classes left over from when this file was copied from Alpha, and rename ArithmeticOverflowFault to be IntegerOverflowFault and get rid of the old IntegerOverflowFault stub. The Integer version is what's actually in the manual, but the Arithmetic version had the implementation.
2011-09-19MIPS: Add constructors to the fault classes.Gabe Black
