678abbc364 syscall: Avoid a compiler warning which turns into a bug. 
Simply cast the result to an int and life is good.

4b1e0d235d scons: Get rid of generate.py in the build system. 
I decided that separating some of the scons code into generate.py was
just a bad idea because it caused the dependency system to get all
messed up.  If separation is the right way to go in the future, we
should probably use the sconscript mechanism, not the mechanism that I
just removed.

f3a3ab7f2c syscall: Fix TTY emulation in fstat() user-mode simulation for fd 1 (stdout).

5f42bfcd56 process: separate stderr from stdout 
- Add the option of redirecting stderr to a file. With the old
behaviour, stderr would follow stdout if stdout was to a file, but
stderr went to the host stderr if stdout went to the host stdout.  The
new default maintains stdout and stderr going to the host.  Now the
two can specify different files, but they will share a file descriptor
if the name of the files is the same.
- Add --output and --errout options to se.py to go with --input.

a8df952dd3 tests: update config.ini and stdout for the various tests. 
These files were a bit too out of date and resulted in a bit of confusion.

aa2bb4f7b9 Get rid of useless m5_assert macro. 
Its only purpose was to print the cycle number but that already
happens in the SIGABRT handler.  No one used it anyway.

f90b08a5cc eventq: change the event datastructure back to LIFO. 
The status quo is preferred since it is less likely that people will
rely on LIFO than FIFO, and when we move to a parallelized M5, no
ordering between events of the same time/priority will be guaranteed.

10df68dd72 eventq: new eventq data structure. The new data structure is singly 
linked list sorted by time and priority.  For things of the same time
and priority, a second, circularly linked list maintains the data
structure.  Events of the same time and priority are now inserted in
FIFO order instead of LIFO order.  This dramatically improves the
performance of systems that schedule multiple events at the same time.

The FIFO order version is not preferred to LIFO (because it may cause
people to rely on it), but I'm going to commit it anyway and
immediately commit the preferred LIFO version on top.

93517dd90c eventq: Clean up the Event class so that it uses fewer bytes. This 
will hopefullly allow it to fit in a cache line.

a4a7a09e96 Remove delVirtPort() and make getVirtPort() only return cached version. 2008-07-01 10:25:07 -04:00
Ali Saidi
c5fbbf376a Change everything to use the cached virtPort rather than created their own each time. 
This appears to work, but I don't want to commit it until it gets tested a lot more.
I haven't deleted the functionality in this patch that will come later, but one question
is how to enforce encourage objects that call getVirtPort() to not cache the virtual port
since if the CPU changes out from under them it will be worse than useless. Perhaps a null
function like delVirtPort() is still useful in that case.

50e3e50e1a Make the cached virtPort have a thread context so it can do everything that a newly created one can. 2008-07-01 10:24:16 -04:00

9bd0bfe559 After a checkpoint (and thus a stats reset), the not_idle_fraction/notIdleFraction statistic is really wrong. 
The notIdleFraction statistic isn't updated when the statistics reset, probably because the cpu Status information
was pulled into the atomic and timing cpus. This changeset pulls Status back into the BaseSimpleCPU object. Anyone
care to comment on the odd naming of the Status instance? It shouldn't just be status because that is confusing
with Port::Status, but _status seems a bit strage too.
