3864 5578 d 16 h rimsky /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.  
3863 5579 d 15 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 5582 d 16 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3835 5587 d 15 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 5595 d 15 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.  
3801 5599 d 17 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Minor fixes in the preemptible trap handler.  
3798 5600 d 16 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 5612 d 17 h rimsky /branches/sparc/kernel/arch/sparc64/ Machine description traversal implemented. Now used to detect CPU frequency.  
3771 5615 d 17 h rimsky /branches/sparc/kernel/arch/sparc64/ Forgotten files comitted to repository.  
3770 5615 d 17 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 5622 d 18 h rimsky /branches/sparc/kernel/arch/sparc64/ Be careful to preserve the output registers when processing the fast data access MMU miss.  
3745 5623 d 0 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3743 5623 d 1 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 5623 d 2 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5646 d 15 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5646 d 15 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 5656 d 16 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 5657 d 14 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5657 d 18 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5661 d 15 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.
