4638	5593 d 7 h	rimsky	/branches/sparc/kernel/	SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism.
3993	5726 d 0 h	rimsky	/branches/sparc/kernel/	Implemented preemptible trap handler for userspace (including syscalls - did not forget enabling interrupts for them) and the ralated stuff. Implemented handlers of instruction/data MMU miss/protection. Now some userspace tasks are run; there are, however, still some bugs causing unexpected data MMU misses.
3862	5751 d 0 h	rimsky	/branches/sparc/kernel/	Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.
3770	5784 d 1 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).
3743	5791 d 10 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.
