d90456a486 X86: Implement the stul microop. 
This microop does a store and unlocks the requested address. The RISC86
microop ISA doesn't seem to have an equivalent to this, so I'm guessing that
the store following an ldstl is automatically unlocking. We don't do it this
way for performance reasons since the behavior is the same.

d2554ff030 X86: Implement the ldstl microop.

requested address.

d8a34a9745 mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use TLBS correcty in SE mode. The error was forwarding translations directly to pageTable.

8882dc1283 Get rid of the Unallocated thread context state. 
Basically merge it in with Halted.
Also had to get rid of a few other functions that
called ThreadContext::deallocate(), including:
 - InOrderCPU's setThreadRescheduleCondition.
 - ThreadContext::exit().  This function was there to avoid terminating
   simulation when one thread out of a multi-thread workload exits, but we
   need to find a better (non-cpu-centric) way.

dd6ea8797f scons: Require SCons version 0.98.1 
This allows me to clean things up so we are up to date with respect to
deprecated features.  There are many features scheduled for permanent failure
in scons 2.0 and 0.98.1 provides the most compatability for that.  It
also paves the way for some nice new features that I will add soon

f1430941cf This brings M5 closer to modernity - the kernel being advertised is newer so it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack.

b760b99f4d O3CPU: Undo Gabe's changes to remove hwrei and simpalcheck from O3 CPU. Removing hwrei causes 
the instruction after the hwrei to be fetched before the ITB/DTB_CM register is updated in a call pal
call sys and thus the translation fails because the user is attempting to access a super page address.

Minimally, it seems as though some sort of fetch stall or refetch after a hwrei is required. I think
this works currently because the hwrei uses the exec context interface, and the o3 stalls when that occurs.

Additionally, these changes don't update the LOCK register and probably break ll/sc. Both o3 changes were
removed since a great deal of manual patching would be required to only remove the hwrei change.

91d968783e Return an UnimpFault for an ITB translation of an uncachable address. We don't support fetching from uncached addresses in Alpha and it means that a speculative fetch can clobber device registers. 2008-08-13 16:29:59 -04:00

ee62a0fec8 params: Convert the CPU objects to use the auto generated param structs. 
A whole bunch of stuff has been converted to use the new params stuff, but
the CPU wasn't one of them.  While we're at it, make some things a bit
more stylish. Most of the work was done by Gabe, I just cleaned stuff up
a bit more at the end.

a4a7a09e96 Remove delVirtPort() and make getVirtPort() only return cached version. 2008-07-01 10:25:07 -04:00

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.
