2011-01-10RefCount: Add a unit test for reference counting pointers.Gabe Black
This test exercises each of the functions in the reference counting pointer implementation individually (except get()) and verifies they have some minimially expected behavior. It also checks that reference counted objects are freed when their usage count goes to 0 in some basic situations, specifically a pointer being set to NULL and a pointer being deleted.
2011-01-07Replace curTick global variable with accessor functions.Steve Reinhardt
This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
2011-01-07stats: rename StatEvent() function to schedStatEvent().Steve Reinhardt
This follows the style rules and is more descriptive.
2011-01-07sim: clean up CountedDrainEvent slightly.Steve Reinhardt
There's no reason for it to derive from SimLoopExitEvent. This whole drain thing needs to be redone eventually, but this is a stopgap to make later changes to SimLoopExitEvent feasible.
2011-01-07sim: delete unused CheckSwapEvent code.Steve Reinhardt
There's no way to even create one of these anymore.
2011-01-07pseudoinst: get rid of mainEventQueue references.Steve Reinhardt
Avoid direct references to mainEventQueue in pseudo-insts by indirecting through associated CPU object. Made exitSimLoop() more flexible to enable some of these.
2011-01-07inorder: replace schedEvent() code with reschedule().Steve Reinhardt
There were several copies of similar functions that looked like they all replicated reschedule(), so I replaced them with direct calls. Keeping this separate from the previous cset since there may be some subtle functional differences if the code ever reschedules an event that is scheduled but not squashed (though none were detected in the regressions).
2011-01-07inorder: get rid of references to mainEventQueue.Steve Reinhardt
Events need to be scheduled on the queue assigned to the SimObject, not on the global queue (which should be going away). Also cleaned up a number of redundant expressions that made the code unnecessarily verbose.
2011-01-07scons: show sources and targets when building, and colorize output.Steve Reinhardt
I like the brevity of Ali's recent change, but the ambiguity of sometimes showing the source and sometimes the target is a little confusing. This patch makes scons typically list all sources and all targets for each action, with the common path prefix factored out for brevity. It's a little more verbose now but also more informative. Somehow Ali talked me into adding colors too, which is a whole 'nother story.
2011-01-04Ruby: Updates MOESI Hammer protocolNilay Vaish
This patch changes the manner in which data is copied from L1 to L2 cache in the implementation of the Hammer's cache coherence protocol. Earlier, data was copied directly from one cache entry to another. This has been broken in to two parts. First, the data is copied from the source cache entry to a transaction buffer entry. Then, data is copied from the transaction buffer entry to the destination cache entry. This has been done to maintain the invariant - at any given instant, multiple caches under a controller are exclusive with respect to each other.
2011-01-04Params: Print the IP components in the right order.Gabe Black
2011-01-03Move sched_list.hh and timebuf.hh from src/base to src/cpu.Steve Reinhardt
These files really aren't general enough to belong in src/base. This patch doesn't reorder include lines, leaving them unsorted in many cases, but Nate's magic script will fix that up shortly. --HG-- rename : src/base/sched_list.hh => src/cpu/sched_list.hh rename : src/base/timebuf.hh => src/cpu/timebuf.hh
2011-01-03Delete unused files from src/base directory.Steve Reinhardt
2011-01-03Make commenting on close namespace brackets consistent.Steve Reinhardt
Ran all the source files through 'perl -pi' with this script: s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
2011-01-03RefCount: Fix reference counting pointer == and != with a T* on the left.Gabe Black
These operators were expecting a const T& instead of a const T*, and were not being picked up and used by gcc in the right places as a result. Apparently no one used these operators before. A unit test which exposed these problems, verified the solution, and checks other basic functionality is on the way.
2011-01-03Ruby: Add option for random seed to Ruby.pyNilay Vaish
This patch adds an option to the script Ruby.py for setting the parameter m_random_seed used for randomizing delays in the memory system. The option can be specified as "--random_seed <seed value>".
2010-12-30swig: use <> for system %includes instead of ""Nathan Binkert
2010-12-30style: make style hook work with pre-qrefresh and update to use new codeNathan Binkert
clean up the code a little bit while we're at it. I recommend that everyone adds the pre-qrefresh hook below since it will make qref run the style hook and not just commit/qpush [extensions] style = <m5 path>/util/style.py [hooks] pretxncommit.style = python:style.check_whitespace pre-qrefresh.style = python:style.check_whitespace
2010-12-23PerfectCacheMemory: Add return statements to two functions.Nilay Vaish
Two functions in src/mem/ruby/system/PerfectCacheMemory.hh, tryCacheAccess() and cacheProbe(), end with calls to panic(). Both of these functions have return type other than void. Any file that includes this header file fails to compile because of the missing return statement. This patch adds dummy values so as to avoid the compiler warnings.
2010-12-22This patch removes the WARN_* and ERROR_* from src/mem/ruby/common/Debug.hh ↵Nilay Vaish
file. These statements have been replaced with warn(), panic() and fatal() defined in src/base/misc.hh

2010-12-08ruby: remove Ruby asserts for m5.fastBrad Beckmann
This diff is for changing the way ASSERT is handled in Ruby. m5.fast compiles out the assert statements by using the macro NDEBUG. Ruby uses the macro RUBY_NO_ASSERT to do so. This macro has been removed and NDEBUG has been put in its place.

2010-12-07O3: Allow a store entry to store up to 16 bytes (instead of TheISA::IntReg).Ali Saidi
The store queue doesn't need to be ISA specific and architectures can frequently store more than an int registers worth of data. A 128 bits seems more common, but even 256 bits may be appropriate. Pretty much anything less than a cache line size is buildable.
2010-12-07Stats: Fix stats for cumulative flags change.Ali Saidi
2010-12-07O3: Support squashing all state after special instructionAli Saidi
For SPARC ASIs are added to the ExtMachInst. If the ASI is changed simply marking the instruction as Serializing isn't enough beacuse that only stops rename. This provides a mechanism to squash all the instructions and refetch them
2010-12-07O3: Make all instructions that write a misc. register not perform the write ↵Giacomo Gabrielli
until commit. ARM instructions updating cumulative flags (ARM FP exceptions and saturation flags) are not serialized. Added aliases for ARM FP exceptions and saturation flags in FPSCR. Removed write accesses to the FP condition codes for most ARM VFP instructions: only VCMP and VCMPE instructions update the FP condition codes. Removed a potential cause of seg. faults in the O3 model for NEON memory macro-ops (ARM).

This patch developed by Nilay Vaish converts all the old GEMS-style ruby debug calls to the appropriate M5 debug calls.
2010-11-26IGbE: return 0 on an invalid descriptor size instead of -1.Ali Saidi
Asserts where descSize() get called with assert if we end up returning 0.
2010-11-23Copyright: Add AMD copyright to the param changes I just made.Gabe Black
2010-11-23Params: Add parameter types for IP addresses in various forms.Gabe Black
New parameter forms are: IP address in the format "a.b.c.d" where a-d are from decimal 0 to 255. IP address with netmask which is an IP followed by "/n" where n is a netmask length in bits from decimal 0 to 32 or by "/e.f.g.h" where e-h are from decimal 0 to 255 and which is all 1 bits followed by all 0 bits when represented in binary. These can also be specified as an integral IP and netmask passed in separately. IP address with port which is an IP followed by ":p" where p is a port index from decimal 0 to 65535. These can also be specified as an integral IP and port value passed in separately.
