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

/branches/sparc/kernel/ |
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. |

/branches/sparc/kernel/ |
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). |

Be careful to preserve the output registers when processing the fast data access MMU miss. |

/branches/sparc/ |
Started to implement support for sun4v. Bootloader adapted to autodetect the architecture (sun4u, sun4v). Some generic sparc64 kernel files split into sun4u and sun4v versions (but the sun4u is still the default in many cases - in order to keep the code compilable). Implemented taking over the MMU. Implemented routines for performing the hypervisor API calls. Implemented a trivial standard output driver. HelenOS banner can now be printed from the kernel on Niagara. |

Integrated US-III port into the build process; added script for downloading and patching SILO; added patched SILO binaries; modified sources of the Sparc64 port up to the beginning of the main_bsp_separated_stack function: phys. address size not hardwired but configurable (41 bits on US-II, 43 bits on US-III), WSTATE register implicitly written 0 on startup. |
