3774 5626 d 10 h jermar /trunk/kernel/arch/ia64/include/ More of ia64 cleanup.  
3635 5665 d 5 h vana /trunk/ IA64: Userspace I/O support  
3578 5679 d 17 h vana /trunk/ Alfa of SMP support on IA64  
3233 5786 d 10 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
2726 5955 d 15 h vana /trunk/ Basic IA64 boot and kernel suport for real machines  
2089 6332 d 12 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6338 d 12 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6343 d 5 h jermar /trunk/ (c) versus (C)  
2007 6390 d 3 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
1888 6468 d 8 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6533 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6540 d 8 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6561 d 11 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1210 6614 d 13 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1108 6644 d 3 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
967 6652 d 15 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
901 6665 d 14 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.		  
879 6669 d 6 h vana /kernel/trunk/arch/ia64/ Itanium kernel page extended to maximum (256M) repaired RR manipulation functions, paging setuping function and added some comments.  
870 6672 d 2 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6672 d 2 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
819 6686 d 5 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6686 d 8 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
792 6688 d 11 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
756 6694 d 1 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
751 6695 d 11 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6697 d 9 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6698 d 9 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6699 d 3 h jermar /kernel/trunk/ ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).

Add missing header to sparc64.
Remove excessive header from debug.h.		  
746 6699 d 11 h jermar /kernel/trunk/ Page hash table modifications.  
715 6710 d 7 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
710 6710 d 10 h vana /kernel/trunk/arch/ia64/include/mm/ VHPT entry  
699 6715 d 12 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
691 6717 d 9 h jermar /kernel/trunk/arch/ Cleanup.  
684 6717 d 10 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
537 6751 d 8 h jermar /kernel/trunk/ Buddy system cleanup and fixes.
- missing use of KA2PA in frame_init
- truncating black list addresses to frame boundaries
- removal of left-over obsolete structures

532 6752 d 6 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6764 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.

TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
