SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism. |

Waking CPUs up on sun4v. Weird errors occur when accessing the THE structure. |

Fixed a TSB problem. |

/branches/sparc/kernel/arch/sparc64/ |
Fixed instruction access exception and data access exception in the trap table. Added new traps defined by UltraSPARC Architecture 2007 (which UltraSPARC T2 follows). |

Kernel stack and userspace window buffer pointers are stored in scratchpad registers instead of memory. |

Cleanup of the Niagara port. The main purpose of these changes is to make it easy to find out which code is generic, which is sun4u-specific and which is sun4v-specific. |

Implemented missing features in Niagara memory management, minor cleanup. |

/branches/sparc/ |
Implemented input and output drivers for Niagara. Written in the old-fashion style (do not use the new DDI infrastructure nor the new keyboard driver). Anyway, tetris can be played. |

Workaround for the bug which usually caused rewriting saved register window data on the uspace stack. More investigation needed. |

/branches/sparc/uspace/lib/libc/arch/sparc64/include/ |
Fixed the bug which caused unexpected MMU misses. The fix breaks sun4u ports - this will be solved once the sun4v is integrated with the new configuration mechanism, which allows to define common options for both kernel and uspace. |

Implemented preemptible trap handler for userspace (including syscalls - did not forget enabling interrupts for them) and the ralated stuff. Implemented handlers of instruction/data MMU miss/protection. Now some userspace tasks are run; there are, however, still some bugs causing unexpected data MMU misses. |

Allocated bigger memory block for the Machine Description. This was the problem which prevented running HelenOS on real Niagara. Now all kernel tests except for 'slab2' pass on real Niagara. |

Simics machine: modifications needed to run userspace (the next step will be to implement the trap handler for uspace); real machine: small fixes, after them the machine passes some parts of the initialization, but fails to determine CPU frequency (probably due to a different format of Machine Description). |

Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions. |

Niagara: Implemented (and debugged) installing identity mapping for kernel. Now all the kernel tests pass on Simics. |

Progress on Niagara: Commented out portions of mm, which are not required for kernel threads (temporarily). Scheduler is working. Implemented a driver of hypervisor's standard input. Kernel console is usable. |

Minor fixes in the preemptible trap handler. |

/branches/sparc/kernel/ |
Implemented preemptible trap handler for sun4v for trapping from kernel (not userspace). Not properly tested/debugged yet. HelenOS now reaches the as_install_arch function (where it, of course, fails). |
