1823	6480 d 20 h	jermar	/trunk/kernel/arch/sparc64/	sparc64 work. Dump take_over_tlb_and_tt() and add its assembly language replacement.
1822	6481 d 0 h	jermar	/trunk/	sparc64 work. 1. Formatting fixes. 2. When writing to DMMU ASI's, simple membar() can be used in place of flush(). 3. Substantial changes in the way the TLB is taken over. 4. Remove unneeded functions. This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi processor. Note that 3. needs further work as the current implementation depends on the fact that the compiler will use registers for local variables in take_over_tlb_and_tt(). Rewrite of that function into assembly is to follow.
1787	6501 d 17 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1780	6508 d 18 h	jermar	/kernel/trunk/	Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
1702	6529 d 21 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
901	6634 d 1 h	jermar	/kernel/trunk/arch/	ia64 work. Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler. Add before_thread_runs_arch() that maps kstack, if necessary. Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.
897	6635 d 12 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.
877	6638 d 16 h	jermar	/kernel/trunk/arch/sparc64/	Fixes in sparc64 preliminary TLB miss handler. Compute and insert identity mapping for kernel on the fly.
873	6639 d 0 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add more MMU helper functions and make data TLB miss handler more verbose.
863	6641 d 12 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add initial TLB miss handlers.
658	6703 d 1 h	jermar	/kernel/trunk/arch/sparc64/include/	sparc64 work. Add functions to read and write TICK and TICK_compare registers. Add types describing TICK and TICK_compare registers.
619	6711 d 10 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Functions for disabling/enabling MMU. TLB initialization. Identity mapping of first 4M for kernel. Switch to kernel copy of trap table.
617	6711 d 13 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Support for TLB Demap operations. Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).
613	6712 d 12 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. More ITLB and DTLB controlling functions.
569	6716 d 13 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
534	6720 d 16 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6720 d 16 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
531	6721 d 15 h	jermar	/kernel/trunk/arch/sparc64/include/mm/	sparc64 work. MMU ASI & virtual addresses definitions.
530	6722 d 1 h	jermar	/kernel/trunk/arch/sparc64/include/mm/	sparc64 work. TTE (Translation Table Entry) type definitions.
501	6732 d 20 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
