3863 5748 d 1 h rimsky /branches/sparc/ 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).  
3862 5751 d 1 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3835 5756 d 1 h rimsky /branches/sparc/kernel/arch/sparc64/ Niagara: Implemented (and debugged) installing identity mapping for kernel. Now all the kernel tests pass on Simics.  
3817 5764 d 1 h rimsky /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.  
3798 5769 d 1 h rimsky /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).  
3783 5781 d 2 h rimsky /branches/sparc/kernel/arch/sparc64/ Machine description traversal implemented. Now used to detect CPU frequency.  
3771 5784 d 2 h rimsky /branches/sparc/kernel/arch/sparc64/ Forgotten files comitted to repository.  
3770 5784 d 2 h rimsky /branches/sparc/ 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).  
3748 5791 d 3 h rimsky /branches/sparc/kernel/arch/sparc64/ Be careful to preserve the output registers when processing the fast data access MMU miss.  
3745 5791 d 10 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3743 5791 d 11 h rimsky /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.  
3742 5791 d 11 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5815 d 1 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5815 d 1 h rimsky /branches/sparc/ Added some SunBlade 1500 stuff (part of it is just temporary - e.g. the new visual). Some small fixes and enhancements.  
3618 5825 d 1 h rimsky /branches/sparc/ Support for framebuffers, where the first pixel is mapped to a different address than the OBP 'reg' property claims. Cleanup, comments, C-style.  
3607 5826 d 0 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3593 5830 d 1 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3591 5830 d 9 h rimsky /branches/sparc/ Making the code compatible also with US-IV (US-IV+) - TLB size based on CPU autodetection, cleanup of code waking up APs. General cleanup.  
3582 5835 d 14 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5843 d 0 h rimsky /branches/sparc/ 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).
