1968 6427 d 19 h jermar /tags/ Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.		  
1964 6427 d 19 h jermar /tags/0.2.0/ Tagging release 0.2.0  
1595 6571 d 9 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1411 6584 d 0 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 6587 d 20 h decky /kernel/trunk/ make hardware memory mapping more generic  
1288 6603 d 5 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.		  
1212 6615 d 23 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1064 6652 d 16 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6652 d 17 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1051 6653 d 0 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
825 6688 d 0 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.		  
814 6689 d 4 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
799 6690 d 20 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
793 6691 d 2 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 6696 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.		  
755 6697 d 16 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.		  
691 6720 d 0 h jermar /kernel/trunk/arch/ Cleanup.  
690 6720 d 0 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
687 6720 d 0 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
684 6720 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.
