Enhancing the way how even distribution of threads over processor cores is achieved. |

/branches/sparc/kernel/ |
Implemented detection of execution units, used in a heuristics which prevents the ready threads be unevenly distributed among physical cores by changing the order in which APs are woken up (and hence the order in which the CPUs will be running their kcpulb thread). Cleanup. |

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. |

/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. |

/branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ |
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. |

/branches/sparc/kernel/ |
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. |
