| 315 | * rtems/score/cpu.h: Add the interrupt stack structure and enhance |
---|
| 316 | the context initialization to account for floating point tasks. |
---|
| 317 | * rtems/score/mips.h: Added the routines mips_set_cause(), |
---|
| 318 | mips_get_fcr31(), and mips_set_fcr31(). |

| 322 | |
---|
| 323 | * cpu_asm.S: Merged patches from Gregory Menke |
---|
| 324 | <Gregory.D.Menke.1@gsfc.nasa.gov> that clean up |

| 328 | |
---|
| 329 | * cpu_asm.S: Added code to save and restore SR and EPC to |
---|
| 330 | properly support nested interrupts. Note that the ISR |
---|
| 331 | (not RTEMS) enables interrupts allowing the nesting to occur. |

---|
| 341 | * cpu.c, cpu_asm.S, iregdef.h, rtems/score/cpu.h, rtems/score/mips.h: |
---|
| 342 | Merged MIPS1 and MIPS3 code reducing the number of lines of assembly. |
---|

---|
| 357 | |
---|
| 358 | * cpu_asm.S: Use SR_INTERRUPT_ENABLE_BITS instead of SR_XXX constants |
---|
| 359 | to make it easier to conditionalize the code for various ISA levels. |

---|
| 362 | |
---|
| 363 | * idtcpu.h: Commented out definition of "wait". It was stupid to |
---|
| 364 | use such a common word as a macro. |
---|
| 365 | * rtems/score/cpu.h (_CPU_ISR_Disable): Fixed for mips ISA 3. |
---|
| 366 | * rtems/score/mips.h: Added include of <idtcpu.h>. |

| 389 | on MIPS ISA I. Now call mips_vector_isr_handlers() in libcpu or BSP. |

---|
| 411 | (_CPU_ISR_Set_level): Removed ISA I version and rewrote in C. |

---|
| 460 | |
---|
| 461 | * This is a major reworking of the mips64orion port to use |
---|
| 462 | gcc predefines as much as possible and a big push to multilib |
---|
| 463 | the mips port. The mips64orion port was copied/renamed to mips |
---|
| 464 | to be more like other GNU tools. Alan did most of the technical |
---|
| 465 | work of determining how to map old macro names used by the mips64orion |
---|
| 466 | port to standard compiler macro definitions. Joel did the merge |
---|
| 467 | with CVS magic to keep individual file history and did the BSP |
---|
| 468 | modifications. Details follow: |
---|
| 469 | * Makefile.am: idtmon.h in mips64orion port not present. |
---|
| 470 | * asm.h: MIPS64ORION replaced with MIPS. Frame setup macros added. |
---|
| 471 | * cpu.c: Comments added. |
---|
| 472 | * cpu_asm.S: Conditionals changed. MIPS ISA level 1 support added. |
---|
| 473 | First attempt at exception/interrupt processing for ISA level 1 |
---|
| 474 | and minus any use of IDT/MON added. |
---|
| 475 | * idtcpu.h: Conditionals changed to use gcc predefines. |
---|
| 476 | * iregdef.h: Ditto. |
---|
| 477 | * cpu_asm.h: No real change. Merger required commit. |
---|
| 478 | * rtems/Makefile.am: Ditto. |
---|
| 479 | * rtems/score/Makefile.am: Ditto. |
---|
| 480 | * rtems/score/cpu.h: Change MIPS64ORION to MIPS. |
---|
| 481 | * rtems/score/mips64orion.h: Change MIPS64ORION to MIPS. Convert |
---|
| 482 | from using RTEMS_CPU_MODEL to gcc predefines to figre things out. |
