4383 5508 d 23 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 5512 d 17 h rimsky /branches/sparc/kernel/arch/sparc64/ Kernel stack and userspace window buffer pointers are stored in scratchpad registers instead of memory.  
4129 5569 d 13 h rimsky /branches/sparc/kernel/arch/sparc64/ Implemented missing features in Niagara memory management, minor cleanup.  
4068 5573 d 15 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Fixed a stupid bug.  
4064 5574 d 15 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 5581 d 14 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 5603 d 14 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 5606 d 14 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3835 5611 d 14 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 5623 d 16 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Minor fixes in the preemptible trap handler.  
3798 5624 d 14 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 5639 d 15 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 5647 d 0 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 5670 d 14 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3493 5716 d 16 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5719 d 18 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3489 5723 d 18 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3343 5775 d 20 h decky /branches/sparc/ add sparc branch  
3071 5852 d 22 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2610 6052 d 20 h jermar /trunk/ Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task).
