2007-08-26X86: Make the Ruflag microop work correctly, and make the code a little clearer.Gabe Black
--HG-- extra : convert_revision : c551f51cdda46df99370363ed2d70916db8413eb
2007-08-26X86: Return values for some cpuid functions that match what my development ↵Gabe Black
machine returns. --HG-- extra : convert_revision : e6619da11f43bbe025ceabd06387dd24e1cd883b
2007-08-26X86: Make the microassembler accept lines which are just labels.Gabe Black
The labels on these lines will be associated with whatever the next microop is. --HG-- extra : convert_revision : 80c260e48ec1c16e6325061608e37c95a0610cfa

2007-08-26X86: Make shift instructions set some of the flags they're supposed to.Gabe Black
The flag mechanism for microops needs to be fleshd out a little more to allow for custom flag calculation methods for certain microops. Shift is an example where the rules for calculating OF and CF are unique. --HG-- extra : convert_revision : 91981a00c1efd05db702fffa9cea51f912583013
2007-08-26Address translation: Make the page table more flexible.Gabe Black
The page table now stores actual page table entries. It is still a templated class here, but this will be corrected in the near future. --HG-- extra : convert_revision : 804dcc6320414c2b3ab76a74a15295bd24e1d13d

2007-08-21o3: Fix for retry ID bug.Kevin Lim
It should be cleared prior to the call to recvRetry. Add extra DPRINTF statement for clearer debugging output. --HG-- extra : convert_revision : e2332754743f42d60e159ac89f6fb0fd8b7f57f8

--HG-- extra : convert_revision : 765b096785a77df9adc4791c9101b90696bd7be2
2007-08-13SPARC: Make nops have the IsNop flag set.Gabe Black
In O3, a nop is used to carry faults down the pipeline that didn't originate from an instruction. If the instruction doesn't do anything, that is just returns NoFault, but doesn't have IsNop set, the NoFault will overwrite the fault that's being sent down and nothing will happen. --HG-- extra : convert_revision : 54d99002b550ca0e1cf14603f588dc1038e3e535
2007-08-13O3: Set up the predicted npc and nnpc for a fault carrying noop so that it ↵Gabe Black
doesn't cause a false branch mispredict. --HG-- extra : convert_revision : 2820597cc966cd7b128cef0dab48fe05089533d7
2007-08-13SPARC: Move tlb state into the tlb.Gabe Black
Each "strand" may need to have a private copy of this state, but I couldn't find anywhere in the spec that said that after looking briefly. This prevents writes to the thread context in o3 which was causing the pipeline to be flushed and stopping any forward progress. The other ASI accessible state will probably need to be accessed differently if/when we get O3 full system up and running. --HG-- extra : convert_revision : fa7fba812d7f76564ef4a23818e60f536710d557
2007-08-13SPARC: Make the spill and fill handlers use the correct ASI, and let ↵Gabe Black

2007-08-13python: make the DictImporter's unload() work in any context.Nathan Binkert
import sys since sys may not be defined in whatever context the DictImporter is used. Also reset self.installed after an unload since the same DictImporter could be used again --HG-- extra : convert_revision : 988ed7ad8cd41b69e8fc583e618b1b4a146216da

2007-08-04X86: Make 64 bit unaligned accesses work as well as the other sizes.Gabe Black
There is a fundemental flaw in how unaligned accesses are supported, but this is still an improvement. --HG-- extra : convert_revision : 1c20b524ac24cd4a812c876b067495ee6a7ae29f

2007-08-04X86: Make fixed register operands ignore register index extensions from the ↵Gabe Black
REX prefix. The only cases where this was the correct behavior are now handled with the "B" operand type, and doing things this way was breaking some instructions, notably a shift. --HG-- extra : convert_revision : 072346d4f541edaceba7aecc26ba8d2cd756e481
