Gabe Black aff57202b4 X86: Fix the high result of mul1s, and removed undefined shifts from the mult microops. 2009-08-02 08:39:29 -07:00
Steve Reinhardt 1c28004654 Clean up some inconsistencies with Request flags. 2009-08-01 22:50:13 -07:00

Gabe Black 4971331b4f ARM: Mul and mla ignore the c and v flags, but we were setting them to 1. 2009-07-29 22:24:00 -07:00
Gabe Black b066e717f4 ARM: Fix an instruction in the cmpxchg kernel provided routine. 
The instruction was encoded as a load instead of the intended store.
 2009-07-29 00:18:26 -07:00
Gabe Black c2da5bae17 ARM: Get rid of a stray line in the set_tls handler. 2009-07-29 00:17:20 -07:00
Gabe Black 1e04b6281d ARM: Make the ARM native tracer stop M5 if control diverges. 
If the control flow of M5's executable and statetrace's target process get out
of sync even a little, there will be a LOT of output, very little of which
will be useful. There's also almost no hope for recovery. In those cases, we
might as well give up and not generate a huge, mostly worthless trace file.
 2009-07-29 00:17:11 -07:00
Gabe Black 873112ea99 ARM: Make sure the target process doesn't run away from statetrace. 2009-07-29 00:14:43 -07:00

Gabe Black 52b4a7c36f ARM: Only send information that changed between statetrace and M5. 2009-07-27 00:54:30 -07:00

Gabe Black a41e132007 ARM: Make native trace only print when registers are changing value. 
When registers have incorrect values but aren't actively changing, it's likely
they're not being modified at all. The fact that they're still wrong isn't
very important.
 2009-07-27 00:52:01 -07:00

Korey Sewell 1f4c954590 inorder-mips: Remove eaComp & memAcc; use 'visible' eaComp 
Inorder expects eaComp to be visible through StaticInst object. This mirrors a similar change
to ALPHA... Needs to be done for SPARC and whatever other ISAs want to use InOrderCPU

Korey Sewell db2b721380 inorder-tlb-cunit: merge the TLB as implicit to any memory access 
TLBUnit no longer used and we also get rid of memAccSize and memAccFlags functions added to ISA and StaticInst
since TLB is not a separate resource to acquire. Instead, TLB access is done before any read/write to memory
and the result is checked before it's sent out to memory.

Korey Sewell 6211fe5d2e inorder-float: Fix storage of FP results 
inorder was incorrectly storing FP values and confusing the integer/fp storage view of floating point operations. A big issue was knowing trying to infer when were doing single or double precision access
because this lets you know the size of value to store (32-64 bits). This isnt exactly straightforward since alpha uses all 64-bit regs while mips/sparc uses a dual-reg view. by getting this value from
the actual floating point register file, the model can figure out what it needs to store

Korey Sewell 5127ea226a inorder-unified-tlb: use unified TLB instead of old TLB model 2009-05-12 15:01:14 -04:00
Korey Sewell 2012202b06 inorder/alpha-isa: create eaComp object visible to StaticInst through ISA 
Remove subinstructions eaComp/memAcc since unused in CPU Models. Instead, create eaComp that is visible from StaticInst object. Gives InOrder model capability of generating address without actually initiating access

Korey Sewell b569f8f0ed inorder-bpred: edits to handle non-delay-slot ISAs 
Changes so that InOrder can work for a non-delay-slot ISA like Alpha. Typically, changes have to do with handling misspeculated branches at different points in pipeline
 2009-05-12 15:01:14 -04:00
Korey Sewell 1c8dfd9254 inorder-alpha-port: initial inorder support of ALPHA 
Edit AlphaISA to support the inorder model. Mostly alternate constructor functions and also a few skeleton multithreaded support functions
* * *
Remove namespace from header file. Causes compiler issues that are hard to find
* * *
Separate the TLB from the CPU and allow it to live in the TLBUnit resource. Give CPU accessor functions for access and also bind at construction time
* * *
Expose memory access size and flags through instruction object
(temporarily memAccSize and memFlags to get TLB stuff working.)

Gabe Black 88ab4bb257 X86: Make the local APICs register themselves with the IO APIC. 
This is a hack so that the IO APIC can figure out information about the local
APICs. The local APICs still have no way to find out about each other.
Ideally, when the local APICs update state that's relevant to somebody else,
they'd send an update to everyone. Without being able to do a broadcast, that
would still require knowing who else there is to notify. Other broadcasts are
implemented using assumptions that may not always be true.
 2009-04-26 02:09:13 -07:00
Gabe Black c5e2cf841d X86: Record the initial APIC ID which identifies an APIC in M5. 
The ID as exposed to software can be changed. Tracking those changes in M5
would be cumbersome, especially since there's no guarantee the IDs will remain
unique.

Steve Reinhardt 52b6764f31 syscall: Resolve conflicts between m5threads and Gabe's recent SE changes. 2009-04-21 08:17:36 -07:00
Daniel Sanchez b0e9654f86 Commit m5threads package. 
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

Gabe Black 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.
 2009-04-19 04:55:58 -07:00
Gabe Black d2554ff030 X86: Implement the ldstl microop. 
This microop does a load, checks that a store would succeed, and locks the
requested address.
