2292 6830 d 5 h hudecek /branches/rcu/ updated to latest trunk revision, minor tweaks in tasklet.c  
2131 6864 d 22 h decky /branches/ add development branches  
2089 6920 d 1 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6930 d 18 h jermar /trunk/ (c) versus (C)  
1851 7080 d 1 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1787 7120 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 7127 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 7149 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1424 7165 d 21 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.		  
1380 7172 d 19 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1266 7192 d 1 h jermar /kernel/trunk/genarch/ Rename acpi/matd.c to madt.c (Multiple APIC Description Table).
Improve Doxygen comments in genarch/.		  
1248 7195 d 22 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 7199 d 2 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1044 7238 d 2 h jermar /kernel/trunk/ Page table locking.  
922 7244 d 17 h jermar /kernel/trunk/genarch/src/mm/ Fix generic page hash table to align down page addresses.
This was the ia64 userspace show stopper.		  
902 7253 d 2 h jermar /kernel/trunk/ ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.

Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.		  
826 7272 d 17 h jermar /kernel/trunk/ Add page_mapping_remove().  
823 7273 d 15 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
815 7274 d 2 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
793 7276 d 0 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.		  
792 7276 d 0 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
757 7280 d 18 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.		  
756 7281 d 15 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 7282 d 14 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.		  
746 7287 d 1 h jermar /kernel/trunk/ Page hash table modifications.  
699 7303 d 1 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
687 7304 d 22 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
684 7305 d 0 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.
