2009-10-27POWER: Add support for the Power ISATimothy M. Jones
This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.

2009-10-24syscall: Addition of an ioctl command code for Power.Timothy M. Jones
2009-10-24syscall: Zero out memory that already exists during the brk system call.Timothy M. Jones
Glibc often assumes that memory it receives from the kernel after a brk system call will contain only zeros. This is important during a calloc, because it won't clear the new memory itself. In the simulator, if the new page exists, it will be cleared using this patch, to mimic the kernel's functionality.

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.

2009-09-26python: Fix m5.defines so grabbing flags works correctlyNathan Binkert
2009-09-26O3: Add flag to control whether faulting instructions are traced.Steve Reinhardt
When enabled, faulting instructions appear in the trace twice (once when they fault and again when they're re-executed). This flag is set by the Exec compound flag for backwards compatibility.
2009-09-26Minor cleanup: Use the blockAlign() method where it applies in the cache.Steve Reinhardt
2009-09-26Force prefetches to check cache and MSHRs immediately prior to issue.Steve Reinhardt
This prevents redundant prefetches from being issued, solving the occasional 'needsExclusive && !blk->isWritable()' assertion failure in cache_impl.hh that several people have run into. Eliminates "prefetch_cache_check_push" flag, neither setting of which really solved the problem.
2009-09-26O3: Mark fetch stage as active if it faults.Steve Reinhardt
Otherwise if the rest of the pipeline is idle then fault will never propagate to commit to be handled, causing CPU to deadlock.

2009-09-23isa_parser: Turn the ISA Parser into a subclass of Grammar.Nathan Binkert
This is to prepare for future cleanup where we allow SCons to create a separate grammar class for each ISA

2009-09-22slicc: Pure python implementation of slicc.Nathan Binkert
This is simply a translation of the C++ slicc into python with very minimal reorganization of the code. The output can be verified as nearly identical by doing a "diff -wBur". Slicc can easily be run manually by using util/slicc
2009-09-22params: small cleanup to param description internalsNathan Binkert
2009-09-22scons: add slicc and ply to sys.path and PYTHONPATH so everyone has accessNathan Binkert
2009-09-22python: Move more code into m5.util allow SCons to use that code.Nathan Binkert
Get rid of misc.py and just stick misc things in __init__.py Move utility functions out of SCons files and into m5.util Move utility type stuff from m5/__init__.py to m5/util/__init__.py Remove buildEnv from m5 and allow access only from m5.defines Rename AddToPath to addToPath while we're moving it to m5.util Rename read_command to readCommand while we're moving it Rename compare_versions to compareVersions while we're moving it. --HG-- rename : src/python/m5/convert.py => src/python/m5/util/convert.py rename : src/python/m5/smartdict.py => src/python/m5/util/smartdict.py
