1780 6707 d 15 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6728 d 18 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1468 6741 d 16 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1411 6748 d 15 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1382 6752 d 11 h decky /kernel/trunk/ make hardware memory mapping more generic  
1288 6767 d 21 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1044 6817 d 20 h jermar /kernel/trunk/ Page table locking.  
977 6819 d 18 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
965 6819 d 23 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
955 6820 d 13 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
826 6852 d 10 h jermar /kernel/trunk/ Add page_mapping_remove().  
793 6855 d 17 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
756 6861 d 8 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.		  
755 6862 d 8 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.		  
699 6882 d 19 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
687 6884 d 16 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
684 6884 d 17 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.		  
534 6919 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6919 d 13 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6931 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.
