2010-08-23X86: Create a directory for files that define register indexes.Gabe Black
This is to help tidy up arch/x86. These files should not be used external to the ISA. --HG-- rename : src/arch/x86/apicregs.hh => src/arch/x86/regs/apic.hh rename : src/arch/x86/floatregs.hh => src/arch/x86/regs/float.hh rename : src/arch/x86/intregs.hh => src/arch/x86/regs/int.hh rename : src/arch/x86/miscregs.hh => src/arch/x86/regs/misc.hh rename : src/arch/x86/segmentregs.hh => src/arch/x86/regs/segment.hh
2010-08-17sim: revamp unserialization procedureSteve Reinhardt
Replace direct call to unserialize() on each SimObject with a pair of calls for better control over initialization in both ckpt and non-ckpt cases. If restoring from a checkpoint, loadState(ckpt) is called on each SimObject. The default implementation simply calls unserialize() if there is a corresponding checkpoint section, so we get backward compatibility for existing objects. However, objects can override loadState() to get other behaviors, e.g., doing other programmed initializations after unserialize(), or complaining if no checkpoint section is found. (Note that the default warning for a missing checkpoint section is now gone.) If not restoring from a checkpoint, we call the new initState() method on each SimObject instead. This provides a hook for state initializations that are only required when *not* restoring from a checkpoint. Given this new framework, do some cleanup of LiveProcess subclasses and X86System, which were (in some cases) emulating initState() behavior in startup via a local flag or (in other cases) erroneously doing initializations in startup() that clobbered state loaded earlier by unserialize().

2009-11-04X86: Hook up time syscall on X86Vince Weaver
This has been tested and verified that it works.
2009-10-30X86: Hookup truncate/ftruncate syscalls on X86Vince Weaver
This patch hooks up the truncate, ftruncate, truncate64 and ftruncate64 system calls on 32-bit and 64-bit X86. These have been tested on both architectures. ftruncate/ftruncate64 is needed for the f90 spec2k benchmarks.
2009-10-30Syscalls: Make system calls access arguments like a stack, not an array.Gabe Black
When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job.

2009-10-20hook up stat64 syscall on 32-bit X86_SEVince Weaver
2009-10-20Fix stat64 structure on 32-bit X86_SEVince Weaver
The st_size entry was in the wrong place (see linux-2.6.29/arch/x86/include/asm/stat.h ) Also, the packed attribute is needed when compiling on a 64-bit machine, otherwise gcc adds extra padding that break the layout of the structure.
2009-10-19Enable getuid and getgid related syscalls on X86_SEVince Weaver
I've tested these on x86 and they work as expected. In theory for 32-bit x86 we should have some sort of special handling for the legacy 16-bit uid/gid syscalls, but in practice modern toolchains don't use the 16-bit versions, and m5 sets the uid and gid values to be less than 16-bits anyway. This fix is needed for the perl spec2k benchmarks to run.
2009-10-16Ignore rt_sigaction() syscalls on x86 and x86_64Vince Weaver
This is currently how alpha handles this syscall. This is needed for the gcc spec2k benchmarks to run.
2009-10-10Hook up the munmap() syscall for 32-bit x86.Vince Weaver
This is straightforward, as munmapFunc() doesn't do anything. I've tested it with code running munmap() just in case.

2009-07-08Registers: Add a registers.hh file as an ISA switched header.Gabe Black
This file is for register indices, Num* constants, and register types. copyRegs and copyMiscRegs were moved to utility.hh and utility.cc. --HG-- rename : src/arch/alpha/regfile.hh => src/arch/alpha/registers.hh rename : src/arch/arm/regfile.hh => src/arch/arm/registers.hh rename : src/arch/mips/regfile.hh => src/arch/mips/registers.hh rename : src/arch/sparc/regfile.hh => src/arch/sparc/registers.hh rename : src/arch/x86/regfile.hh => src/arch/x86/registers.hh
2009-04-21Commit m5threads package.Daniel Sanchez
This patch adds limited multithreading support in syscall-emulation mode, by using the clone system call. The clone system call works for Alpha, SPARC and x86, and multithreaded applications run correctly in Alpha and SPARC.
