df14312e08 Curtick: Fix mysql.cc build needing curTick. 2011-01-10 04:53:20 -08:00

dc64732dee RefCount: Add a unit test for reference counting pointers.
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.

6f1187943c Replace curTick global variable with accessor functions.
This step makes it easy to replace the accessor functions
(which still access a global variable) with ones that access
per-thread curTick values.

c22be9f2f0 stats: rename StatEvent() function to schedStatEvent().
This follows the style rules and is more descriptive.

94807214c4 sim: clean up CountedDrainEvent slightly.
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.

030736a69b sim: delete unused CheckSwapEvent code.
There's no way to even create one of these anymore.

df9f99567d pseudoinst: get rid of mainEventQueue references.
Avoid direct references to mainEventQueue in pseudo-insts
by indirecting through associated CPU object.
Made exitSimLoop() more flexible to enable some of these.

d60c293bbc inorder: replace schedEvent() code with reschedule().
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).

214cc0fafc inorder: get rid of references to mainEventQueue.
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.

d650f4138e scons: show sources and targets when building, and colorize output.
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.

d36cc62c11 Ruby: Updates MOESI Hammer protocol
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.

89cf3f6e85 Move sched_list.hh and timebuf.hh from src/base to src/cpu.
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

c69d48f007 Make commenting on close namespace brackets consistent.
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.

1a10ccc5e5 RefCount: Fix reference counting pointer == and != with a T* on the left.
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.

5e25f31712 Ruby: Add option for random seed to Ruby.py
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>".

fe6574ecc0 style: make style hook work with pre-qrefresh and update to use new code
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

04f5bb34ce PerfectCacheMemory: Add return statements to two functions.
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.

7e42b753e7 ruby: remove Ruby asserts for m5.fast
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.

42ba158479 O3: Allow a store entry to store up to 16 bytes (instead of TheISA::IntReg).
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.

e681c0f7b3 O3: Support squashing all state after special instruction
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

719f9a6d4f O3: Make all instructions that write a misc. register not perform the write 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).

b3de4855c3 Params: Add parameter types for IP addresses in various forms.
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.
