4130 5540 d 21 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.  
4129 5541 d 17 h rimsky /branches/sparc/kernel/arch/sparc64/ Implemented missing features in Niagara memory management, minor cleanup.  
3993 5553 d 18 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 5578 d 18 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3835 5583 d 18 h rimsky /branches/sparc/kernel/arch/sparc64/ Niagara: Implemented (and debugged) installing identity mapping for kernel. Now all the kernel tests pass on Simics.  
3771 5611 d 19 h rimsky /branches/sparc/kernel/arch/sparc64/ Forgotten files comitted to repository.  
3770 5611 d 19 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 5619 d 4 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 5619 d 4 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3618 5652 d 18 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 5653 d 17 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3591 5658 d 2 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.  
3493 5688 d 20 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3489 5695 d 22 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3467 5713 d 19 h rimsky /branches/sparc/ SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.  
3450 5717 d 20 h rimsky /branches/sparc/kernel/arch/sparc64/ Made tlb.h conform US-III specification.  
3440 5719 d 4 h rimsky /branches/sparc/kernel/arch/sparc64/ TLB modifications in order to make functions tlb_print and tlb_invalidate_all work correctly in US-III.  
3343 5748 d 0 h decky /branches/sparc/ add sparc branch  
3233 5771 d 2 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3145 5813 d 8 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, when the operand to the FLUSH instruction doesn't matter, the
instruction's semantics is to flush the pipeline.
