1793	6560 d 22 h	jermar	/trunk/kernel/	Change hw_map() on sparc64 to use virtual addresses that are beyond the end of physical memory. It is beneficial in two ways: first, physical memory is no longer being wasted by otherwise necessary calls to frame_alloc() and, second, virtual addresses for devices are now correctly allocated and do not overlap with the 4M TLB-locked mapping for kernel text and data.
1792	6561 d 12 h	jermar	/trunk/	Move functionality of tlb_arch_init() to take_over_tlb_and_tt(). Call take_over_tlb_and_tt() very early after the kernel starts executing.
1787	6563 d 16 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1780	6570 d 17 h	jermar	/kernel/trunk/	Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
1702	6591 d 20 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
1511	6602 d 19 h	palkovsky	/kernel/trunk/arch/	Remove __address from include file included by uspace
1108	6674 d 12 h	jermar	/kernel/trunk/	Small PTE_* macros and SET_PTL0_ADDRESS macro changes.
1070	6680 d 0 h	jermar	/kernel/trunk/	More checks for address space area conflicts.
977	6682 d 20 h	jermar	/kernel/trunk/	Add sys_mremap() syscall.
967	6682 d 23 h	palkovsky	/kernel/trunk/	Allowed userspace to include page.h.
940	6684 d 15 h	jermar	/kernel/trunk/	Get rid of unneeded macros. Their functionality has been replaced by the ELF loader.
901	6695 d 23 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	6697 d 10 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	6700 d 14 h	jermar	/kernel/trunk/arch/sparc64/	Fixes in sparc64 preliminary TLB miss handler. Compute and insert identity mapping for kernel on the fly.
873	6700 d 22 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add more MMU helper functions and make data TLB miss handler more verbose.
867	6702 d 19 h	jermar	/kernel/trunk/	Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64. sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.
863	6703 d 11 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add initial TLB miss handlers.
792	6718 d 20 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
765	6722 d 13 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
763	6722 d 19 h	jermar	/kernel/trunk/	Modify frame.h to use shifting instead of multiplication and division. Define FRAME_WIDTH for all architectures.
