1852	6470 d 7 h	jermar	/trunk/kernel/	sparc64 work. Bunch of changes in preparation for sparc64 mm and userspace support. Fix alignment of hardcoded_* variables in linker script.
1851	6475 d 12 h	jermar	/trunk/kernel/	sparc64 work. Define the istate structure. Move the identity-mapping handler to assembly. Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it. Little bit of formatting and indentation.
1787	6516 d 8 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
897	6650 d 2 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	6651 d 14 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.
863	6656 d 2 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add initial TLB miss handlers.
667	6710 d 7 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.
666	6712 d 4 h	jermar	/kernel/trunk/	sparc64 work. Fix clean_window trap handler so that it clears output registers instead of input registers! Fix interrupt handlers to save global registers.
664	6714 d 1 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
663	6714 d 14 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Initial interrupt_vector_trap handler and fixes needed to make it do the right thing (i.e. panic()).
634	6723 d 15 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Better way of trap table organization. Kernel trap handlers now "stay" on addresses on wich they were linked.
630	6724 d 6 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
534	6735 d 6 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6735 d 6 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
529	6737 d 10 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add dummy trap tables.
