3665 5814 d 20 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3343 5920 d 2 h decky /branches/sparc/ add sparc branch  
3068 5997 d 4 h decky /trunk/kernel/generic/include/ reflect changes in sources  
2504 6307 d 0 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.
 
2501 6307 d 6 h jermar /trunk/kernel/generic/ Add explicit type for an AVL tree key.
Add function to walk an AVL tree using a supplied walker.
 
2499 6307 d 8 h jermar /trunk/kernel/ Import the AVL tree implementation from the RCU branch.  
2446 6365 d 4 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
 
2106 6483 d 6 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2089 6489 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6499 d 23 h jermar /trunk/ (c) versus (C)  
1888 6625 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1865 6635 d 0 h jermar /trunk/kernel/ sparc64 kernel fixes  
1787 6690 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6697 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6718 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1251 6764 d 5 h jermar /kernel/trunk/ Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there.
 
1200 6775 d 4 h jermar /kernel/trunk/ Add bitmap ADT.  
1177 6780 d 7 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6783 d 3 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1150 6788 d 10 h jermar /kernel/trunk/generic/ Rename btree_node_left_sibling() to btree_leaf_node_left_neighbour()
and btree_node_right_sibling() to btree_leaf_node_right_neighbour()
as the left and right neighbours of a node needn't be its siblings.
 
1147 6788 d 21 h jermar /kernel/trunk/generic/ Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows.
 
1142 6791 d 8 h jermar /kernel/trunk/ Update B+-tree code.
The code is there, btree_remove() has not been tested yet.
(Fixes, if any, are to come later today.)
 
1140 6793 d 1 h jermar /kernel/trunk/generic/ Change B+-tree from 2-3-4 tree to 2-3-4-5 tree by adding space for the fourth key.
This should make key removal easier.
 
1101 6802 d 23 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
 
830 6841 d 5 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().
 
793 6845 d 4 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 6845 d 5 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
790 6845 d 22 h jermar /kernel/trunk/ Generic chaining hash table.  
788 6846 d 1 h jermar /kernel/trunk/ Move list and fifo data types to adt/.
