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

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

/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/ |
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. |

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

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. |

/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). |

Working on Niagara port - TLB initialization, MMU fault status area initialization, hypercall enhancement, modified tick.c so that the (hyperprivileged) TICK register does not have to be accessed. Now the initialization phase proceeds, but some parts of it are omitted for now (e.g. CPU initialization). |

Implemented uspace Serengeti drivers for kbd and fb. Integrated with other parts of HelenOS. Now it is possible to play Tetris on a simulated Serengeti machine (usiii.simics). |

Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable. |

Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option. |

SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks. |
