f5c7b1358c Remove the uncacheable bit 39 check (needs to be merged in with head tree
if Tru64 is to continue to be supported on Turbolaser) and fixed
translation of physical addresses by clearing PA<42:35> when the real
uncachable bit (43) is set

arch/alpha/ev5.hh:
    Change to support 256 ASNs and seperate VA_SPACE checks for EV5 and EV6
    also add support proper translation of uncacheable physical addresses

3bfb59f70d Changes to fix bad DMA handling by disk when using scatter gather page
mappings (writes still unverified, and read could probably be looked over
a bit more too)

dev/ide_disk.cc:
dev/ide_disk.hh:
    Major changes to fix bogus handling of dma transfers.  The read seems to
    work pretty well, but the write is unverfied until we can get a disk
    image that actually tries to write.

782fb42992 Basic cleanup pass to get rid of a few things that made the Python
configuration unnecessarily awkward.  Biggest changes are:

- External and internal object names now match in all cases.  The
macros still allow them to be different; the only reason I didn't
get rid of that is that the macros themselves should be going away
soon.  In the few conflicting cases, I sometimes renamed the C++ object
and sometimes renamed the config object.  The latter sets of substitions
are:

s/BaseBus/Bus/;
s/MemoryObject/FunctionalMemory/;
s/MemoryControl/MemoryController/;
s/FUPool/FuncUnitPool/;

- SamplingCPU is temporarily broken... we need to change the model
of how this works in the .ini file.  Having it as a CPU proxy is
really awkward.

arch/alpha/alpha_memory.cc:
arch/alpha/alpha_memory.hh:
cpu/simple_cpu/simple_cpu.cc:
sim/process.cc:
    Rename objects to match config name.
cpu/base_cpu.cc:
    Uncomment SimObject define since SamplingCPU no longer
    does this for us.
dev/ethertap.cc:
    Use unsigned instead of uint16_t for params.
kern/tru64/tru64_system.cc:
    Use unsigned instead of uint64_t for init_param param.
test/paramtest.cc:
    Fix old SimObjectParam.

b4ff8c555f Make it so that alpha_console can read the frequency from the correct
sim object(depends on which platform tsunami/tlaser is being used)

dev/alpha_console.cc:
    Use dynamice casting once during build to get at the proper device to calculate the frequency.
    It is either a tsunami_IO or a tlaser_clock depending on platform (tsunami/tlaser).
    If the simobject is not of either of those types then panic
dev/alpha_console.hh:
    Pass in a SimObject * that is to either a tlaser_clock or a tsunami_IO
sim/sim_object.cc:
    Make it so that you can have a SimObjectParam of type SimObject:

b6ff600bca Add support for "serializing" instructions that flush
execution pipeline (Alpha trapb & excb).

Add support for write memory barriers (mostly impacts
store buffer).

Add StaticInst flag to indicate memory barriers, though
this is not modeled in the pipeline yet.

arch/alpha/isa_desc:
    Implement trapb, excb, mb, and wmb as insts with
    no execution effect (empty execute() function) but
    with flags that indicate their side effects.

    Also make sure every instruction that needs to go to
    the execute stage has a real opClass value, since we
    are now using No_OpClass to signal insts that can get
    dropped at dispatch.

    StaticInst::branchTarget() is now a const method.
cpu/static_inst.hh:
    Add flags to indicate serializing insts (trapb, excb) and
    memory and write barriers.

    Also declare some StaticInst methods as const methods.
dev/etherlink.hh:
sim/eventq.hh:
sim/serialize.cc:
sim/serialize.hh:

when we are compiling the console.

base/loader/elf_object.cc:
    added code to verify that the .bss section is 0;
    added code to only load function and label types
dev/alpha_access.h:
    include inittypes if we are compiling the console code

510eef0fa0 Modify handling of serialize:dir parameter to make it more useful.
Move global checkpoint-related functions and vars into Checkpoint class (as statics).

arch/alpha/pseudo_inst.cc:
dev/disk_image.cc:
    Move global checkpoint-related functions and vars
    into Checkpoint class (as statics).
sim/serialize.cc:
    Move global checkpoint-related functions and vars
    into Checkpoint class (as statics).

    Checkpoint constructor now takes checkpoint directory name instead
    of file name.

    Make serialize:dir parameter actually set checkpoint directory name
    instead of directory in which checkpoint directory is created.  If
    the value contains a '%', the curTick value is sprintf'd into the
    format to create the directory name.  The default is backwards compatible
    with the old fixed name ("m5.%012d").
sim/serialize.hh:
    Move global checkpoint-related functions and vars
    into Checkpoint class (as statics).

    Checkpoint constructor now takes checkpoint directory name instead
    of file name.

318e0c93ed add support for simple character input via the system console
dev/alpha_access.h:
    -  use our standard types instead of this extra typedef
    -  advance the ALPHA_ACCESS version since the interface
    has changed.  *this means you need a new console binary*
    -  shuffle a couple things around to pack the data structure
    a bit better
    -  add a placeholder for character input
dev/alpha_console.cc:
    Clean up the read code path a bit and add support for character
    input via the console

    Clean up the write path and use a switch instead of a bunch of
    if statements

255ac8372d Make stuff build on openbsd
arch/alpha/alpha_tru64_process.cc:
    So, I don't know why linux uses an off_t here.
    I'm also not sure why linux defines an off_t to be a long
    Let's just use long here since it works for linux, and that's
    what bsd does
base/inifile.cc:
    correct #include for OpenBSD
dev/disk_image.cc:
    the correct type for this is streampos

777c1ebfab Stats & serialization tweaks & cleanup. Unserializing from
a checkpoint now gives identical results to running from scratch
and doing at switchover at the same cycle!
- CPUs start at cycle 0 again, not cycle 1.
- curTick is now serialized & unserialized.
- Stats get reset in main (before event loop).  Since this is done
after curTick is unserialized, simTicks gets set correctly for
running from a checkpoint.
- Simplify serialization to happen in a single pass.

    Reset stats before getting started.
    Make error message on falling out of event loop
    more meaningful.

    Get rid of now-useless initial pass; serialization is
    done in a single pass now.
    Serialize & unserialize curTick.
    Wrap curTick and mainEventQueue in a "globals" Serializable object.

and SimpleCPU::setStatus() into separate functions.  For example,
setStatus(Active) is now activate().
