3665 5718 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 5733 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3343 5824 d 0 h decky /branches/sparc/ add sparc branch  
3233 5847 d 2 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
2726 6016 d 6 h vana /trunk/ Basic IA64 boot and kernel suport for real machines  
2089 6393 d 3 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6399 d 4 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6403 d 20 h jermar /trunk/ (c) versus (C)  
2007 6450 d 19 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 6529 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6593 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6601 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6622 d 2 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1210 6675 d 4 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1108 6704 d 18 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
967 6713 d 6 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
901 6726 d 6 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 6729 d 22 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 6732 d 17 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6732 d 17 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
819 6746 d 20 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6747 d 0 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
792 6749 d 2 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
756 6754 d 17 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 6756 d 2 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6758 d 0 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6759 d 0 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6759 d 18 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 6760 d 3 h jermar /kernel/trunk/ Page hash table modifications.  
715 6770 d 23 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions

684 6778 d 2 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 6812 d 0 h jermar /kernel/trunk/ Buddy system cleanup and fixes.
- missing use of KA2PA in frame_init
