4130 5723 d 20 h rimsky /branches/sparc/ Cleanup of the Niagara port. The main purpose of these changes is to make it easy to find out which code is generic, which is sun4u-specific and which is sun4v-specific.  
4065 5729 d 18 h rimsky /branches/sparc/kernel/arch/sparc64/src/ minor cleanup  
3817 5774 d 17 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 5791 d 18 h rimsky /branches/sparc/kernel/arch/sparc64/ Machine description traversal implemented. Now used to detect CPU frequency.  
3770 5794 d 18 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 5801 d 20 h rimsky /branches/sparc/kernel/arch/sparc64/ Be careful to preserve the output registers when processing the fast data access MMU miss.  
3743 5802 d 3 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.
