4638 5433 d 4 h rimsky /branches/sparc/kernel/ SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism.  
4433 5480 d 1 h rimsky /branches/sparc/kernel/arch/sparc64/ Fixed a TSB problem.  
4383 5493 d 5 h rimsky /branches/sparc/kernel/arch/sparc64/ Fixed instruction access exception and data access exception in the trap table. Added new traps defined by UltraSPARC Architecture 2007 (which UltraSPARC T2 follows).  
4369 5497 d 0 h rimsky /branches/sparc/kernel/arch/sparc64/ Kernel stack and userspace window buffer pointers are stored in scratchpad registers instead of memory.  
4129 5553 d 19 h rimsky /branches/sparc/kernel/arch/sparc64/ Implemented missing features in Niagara memory management, minor cleanup.  
4068 5557 d 22 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Fixed a stupid bug.  
4064 5558 d 21 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Workaround for the bug which usually caused rewriting saved register window data on the uspace stack. More investigation needed.  
3993 5565 d 20 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.  
3863 5587 d 20 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 5590 d 21 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3835 5595 d 21 h rimsky /branches/sparc/kernel/arch/sparc64/ Niagara: Implemented (and debugged) installing identity mapping for kernel. Now all the kernel tests pass on Simics.  
3801 5607 d 23 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Minor fixes in the preemptible trap handler.  
3798 5608 d 21 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).  
3770 5623 d 22 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 5631 d 6 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.  
3665 5654 d 20 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3493 5700 d 22 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5704 d 1 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3489 5708 d 1 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3343 5760 d 2 h decky /branches/sparc/ add sparc branch
