4638 6022 d 20 h rimsky /branches/sparc/kernel/ SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism.  
4433 6069 d 18 h rimsky /branches/sparc/kernel/arch/sparc64/ Fixed a TSB problem.  
4383 6082 d 22 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 6086 d 16 h rimsky /branches/sparc/kernel/arch/sparc64/ Kernel stack and userspace window buffer pointers are stored in scratchpad registers instead of memory.  
4129 6143 d 12 h rimsky /branches/sparc/kernel/arch/sparc64/ Implemented missing features in Niagara memory management, minor cleanup.  
4068 6147 d 14 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Fixed a stupid bug.  
4064 6148 d 14 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 6155 d 13 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 6177 d 13 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 6180 d 13 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3835 6185 d 13 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 6197 d 15 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Minor fixes in the preemptible trap handler.  
3798 6198 d 13 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 6213 d 14 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 6220 d 23 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 6244 d 13 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3493 6290 d 15 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 6293 d 17 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3489 6297 d 17 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3343 6349 d 19 h decky /branches/sparc/ add sparc branch
