3233 5778 d 2 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
2726 5947 d 7 h vana /trunk/ Basic IA64 boot and kernel suport for real machines  
2089 6324 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6330 d 4 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6334 d 21 h jermar /trunk/ (c) versus (C)  
2007 6381 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 6460 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6524 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6532 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6553 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1210 6606 d 5 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1108 6635 d 19 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
967 6644 d 7 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
901 6657 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 6660 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 6663 d 18 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6663 d 18 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
819 6677 d 21 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6678 d 0 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
792 6680 d 3 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
756 6685 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 6687 d 3 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6689 d 1 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6690 d 1 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6690 d 19 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 6691 d 3 h jermar /kernel/trunk/ Page hash table modifications.  
715 6701 d 23 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions

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.
