3743 5608 d 7 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.  
3343 5737 d 3 h decky /branches/sparc/ add sparc branch  
3071 5814 d 5 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
2462 6177 d 0 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.		  
2089 6306 d 7 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6317 d 0 h jermar /trunk/ (c) versus (C)  
1946 6406 d 21 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
- Improve panic screen on data_access_exception
by dumping contents of DSFSR and DSFAR.
- Change the FHC enable interrupt code to only
set the IMAP_V bit.		  
1883 6443 d 6 h jermar /trunk/kernel/arch/sparc64/ More sparc64 FPU trap handlers.  
1882 6443 d 7 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1880 6445 d 23 h jermar /trunk/ Small improvements here and there.  
1870 6450 d 23 h jermar /trunk/kernel/ Handle more sparc64 traps and improve handling of already handled traps.  
1861 6455 d 7 h jermar /trunk/kernel/arch/sparc64/ Convert sparc64 traps using SIMPLE_HANDLER to using PREEMPTIBLE_HANDLER.  
1787 6507 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1735 6530 d 9 h decky /kernel/trunk/ make kernel prints case consistent  
1703 6534 d 12 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6535 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
897 6640 d 20 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 6642 d 8 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 6701 d 1 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.
