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. |

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. |

Making the code compatible also with US-IV (US-IV+) - TLB size based on CPU autodetection, cleanup of code waking up APs. General cleanup. |

Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver. |

More changes making the code US-III-conformant (mainly in mm). |

More files made conform the US-III specification. (Changes concern mainly TSB.) |

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. |

The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.
Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache. |
