| 42 | ; General stuff what happens here: | |
| 43 | ; 1) All general context saved, interrupts off, translation off | |
| 44 | ; 2) Vector and floating point disabled, but there may be live context. | |
| 45 | ; This code is responsible for saving and restoring what is used. This | |
| 46 | ; includes exception states, java mode, etc. | |
| 47 | ; 3) No attempt is made to resolve page faults. PTE misses are handled | |
| 48 | ; automatically, but actual faults (ala copyin/copyout) are not. If | |
| 49 | ; a fault does occur, the exception that caused entry to the emulation | |
| 50 | ; routine is remapped to either an instruction or data miss (depending | |
| 51 | ; upon the stage detected) and redrived through the exception handler. | |
| 52 | ; The only time that an instruction fault can happen is when a different | |
| 53 | ; processor removes a mapping between our original fault and when we | |
| 54 | ; fetch the assisted instruction. For an assisted instruction, data | |
| 55 | ; faults should not occur (except in the MP case). For a purely | |
| 56 | ; emulated instruction, faults can occur. | |
