4383 5710 d 7 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).  
3343 5977 d 4 h decky /branches/sparc/ add sparc branch  
2089 6546 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6557 d 0 h jermar /trunk/ (c) versus (C)  
1883 6683 d 7 h jermar /trunk/kernel/arch/sparc64/ More sparc64 FPU trap handlers.  
1882 6683 d 8 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1880 6686 d 0 h jermar /trunk/ Small improvements here and there.  
1870 6691 d 0 h jermar /trunk/kernel/ Handle more sparc64 traps and improve handling of already handled traps.  
1861 6695 d 8 h jermar /trunk/kernel/arch/sparc64/ Convert sparc64 traps using SIMPLE_HANDLER to using PREEMPTIBLE_HANDLER.  
1860 6696 d 2 h jermar /trunk/kernel/ A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes.		  
1787 6747 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1703 6774 d 13 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6775 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
897 6880 d 21 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
883 6882 d 9 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.		  
667 6941 d 2 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Rename saving_handler() to preemptible_handler()
and fix it to make sparc64 kernel preemptive.
Add two handlers for two fatal exceptions (i.e.
instruction_access_exception and mem_address_not_aligned.
Fix panic_printf() to not allocate its own register window.
