| 2010-01-19 | ruby: new atomics implementation | Derek Hower | |
| This patch changes the way that Ruby handles atomic RMW instructions. This implementation, unlike the prior one, is protocol independent. It works by locking an address from the sequencer immediately after the read portion of an RMW completes. When that address is locked, the coherence controller will only satisfy requests coming from one port (e.g., the mandatory queue) and will ignore all others. After the write portion completed, the line is unlocked. This should also work with multi-line atomics, as long as the blocks are always acquired in the same order. | |||

| 2009-07-06 | ruby: Import the latest ruby changes from gems. | Nathan Binkert | |
| This was done with an automated process, so there could be things that were done in this tree in the past that didn't make it. One known regression is that atomic memory operations do not seem to work properly anymore. | |||
