3864 5760 d 15 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 5761 d 14 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).  
3835 5769 d 14 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 5777 d 14 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.  
3783 5794 d 15 h rimsky /branches/sparc/kernel/arch/sparc64/ Machine description traversal implemented. Now used to detect CPU frequency.  
3770 5797 d 15 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 5804 d 17 h rimsky /branches/sparc/kernel/arch/sparc64/ Be careful to preserve the output registers when processing the fast data access MMU miss.  
3743 5805 d 0 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.
