2010-06-02ARM: Allow ARM processes to start in Thumb mode.Gabe Black
2010-06-02ARM: Detect thumb mode elf images.Gabe Black
2010-05-06compile: don't #include unnecessary stuffNathan Binkert
Time from base/time.hh has a name clash with Time from Ruby's TypeDefines.hh. Eventually Ruby's Time should go away, so instead of fixing this properly just try to avoid the clash.
2010-04-18stats: make simTicks and simFreq accessible from stats.hhNathan Binkert
2010-04-18event: Allow EventWrapper to take an object referenceNathan Binkert
2010-04-15tick: rename Clock namespace to SimClockNathan Binkert
2010-04-15eventq: move EventQueue constructor to cc fileNathan Binkert
Also make copy constructor and assignment operator private.
2010-04-02eventq: allow an implicit cast from an EventManager to an EventQueue *Nathan Binkert
2010-04-02eventq: Clean up some flagsNathan Binkert
- Make the initialized flag always available, not just in debug mode. - Make the Initialized flag actually use several bits so it is very unlikely that something that's uninitialized accidentally looks initialized. - Add an initialized() function that tells you if the current event is indeed initialized. - Clear the flags on delete so it can't be accidentally thought of as initialized. - Fix getFlags assert statement. "How did this ever work?"
2010-04-02eventq: Make priorities just an integer instead of an enum.Nathan Binkert
Symbolic names should still be used, but this makes it easier to do things like: Event::Priority MyObject_Pri = Event::Default_Pri + 1 Remember that higher numbers are lower priority (should we fix this?)

2010-01-19util: do checkpoint aggregation more cleanly, fix last changeset.Lisa Hsu
1) Move alpha-specific code out of page_table.cc:serialize(). 2) Begin serializing M5_pid and unserializing it, but adding an function to do optional paramIn so that old checkpoints don't need to be fixed up. 3) Fix up alpha startup code so that the unserialized M5_pid value is properly written to DTB_IPR_ASN. 4) Fix the memory unserialize that I forgot somehow in the last changeset. 5) Add in an agg_se.py to handle aggregated checkpoints. --bench foo-bar plus positional arguments foo bar are the only changes in usage from se.py. Note this aggregation stuff has only been tested for Alpha and nothing else, though it should take a very minimal amount of work to get it to work with another ISA.
2010-01-18 util: make a generic checkpoint aggregator that can aggregate different ↵Lisa Hsu
cpts into one multi-programmed cpt. Make minor changes to serialization/unserialization to get it to work properly. Note that checkpoints were made with a comment at the beginning with // - this must be changed to ## to work properly with the python config parser in the aggregator.
2010-01-12faults: i think these fault invocations should be panic and not fatal. it ↵Lisa Hsu
definitely made implementing a trace cpu easier this way.
2009-11-14SE: Fix SE mode OS X compilation.Ali Saidi
2009-11-09syscall: missing initializer in getcwd callVince Weaver
This one case was missed during the update to stack-based arguments. Without this fix, m5 will crash during a gwtcwd call, at least with X86.
2009-11-04build: fix compile problems pointed out by gcc 4.4Nathan Binkert
2009-10-30SysCalls: Implement truncate64 system callVince Weaver
This uses the new stack-based argument infrastructure. Tested on x86 and x86_64.
2009-10-31Syscalls: Fix a warning turned error about an unused variable in m5.fast.Gabe Black
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.
2009-10-27POWER: 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.

2009-09-22python: 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

2009-07-10SPARC: Set up a lookup table for integer register flattening.Gabe Black
Using a look up table changed the run time of the SPARC_FS solaris boot regression from: real 14m45.951s user 13m57.528s sys 0m3.452s to: real 12m19.777s user 12m2.685s sys 0m2.420s
2009-07-08Registers: Add a registers.hh file as an ISA switched header.Gabe Black

2009-05-04scons: re-work the *Source functions to take more information.Nathan Binkert
Start by turning all of the *Source functions into classes so we can do more calculations and more easily collect the data we need. Add parameters to the new classes for indicating what sorts of flags the objects should be compiled with so we can allow certain files to be compiled without Werror for example.

2009-04-21syscall: Resolve conflicts between m5threads and Gabe's recent SE changes.Steve Reinhardt
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.
