Make sparc64 kernel assume it is loaded by our loader. |

/kernel/trunk/arch/sparc64/ |
Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory. |

Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof. |

Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler. |

/kernel/trunk/ |
Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention. |

sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse. |

/kernel/trunk/ |
sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32. |

sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore. |

Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory. |
|

6902 d 19 h |

/kernel/trunk/ |
Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory. |

Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs. |
|
| 727 |
6914 d 21 h |

/kernel/trunk/ |
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |
|

/kernel/trunk/ |
Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface. |

sparc64 work.
Rename saving_handler() to preemptible_handler()
and fix it to make sparc64 kernel preemptive.
Add two handlers for two fatal exceptions (i.e.
instruction_access_exception and mem_address_not_aligned.
Fix panic_printf() to not allocate its own register window. |

Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.
sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop. |

For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).
