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). |

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). |

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. |

Added some SunBlade 1500 stuff (part of it is just temporary - e.g. the new visual). Some small fixes and enhancements. |

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). |

Implemented Serengeti console driver (only output, input TBD), all output now goes to the console instead of Simics CLI window. |

Names containing 'UPA' replaced with strings containing more general 'ICBUS'. SMART_FIRMWARE option replaced with CPU autodetection + new option CONFIG_A_OUT_ISOFS_B. |

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. |

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. |

memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this. |

Split mktmpfs.py to a TMPFS specific part and a HORD specific part. The latter
is moved to mkhord.py and can be reused for FAT16 images as well. mktmpfs.py and
mkfat.sh define the same interface now. Modify makefiles to use the modified
interface (e.g. do not pass alignment to either mktmpfs.py or mkfat.sh). FAT16
initrd image can be now loaded as initrd on amd64 and gets recognized as a
ramdisk image. |
