2499 6190 d 4 h jermar /trunk/kernel/ Import the AVL tree implementation from the RCU branch.  
2446 6248 d 0 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 6366 d 2 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 6372 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6382 d 19 h jermar /trunk/ (c) versus (C)  
1888 6507 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1865 6517 d 21 h jermar /trunk/kernel/ sparc64 kernel fixes  
1787 6572 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6579 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6601 d 1 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1251 6647 d 1 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 6658 d 0 h jermar /kernel/trunk/ Add bitmap ADT.  
1177 6663 d 3 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6665 d 23 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1150 6671 d 7 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 6671 d 18 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 6674 d 5 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 6675 d 21 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 6685 d 19 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
 
830 6724 d 2 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().
