3675 5690 d 23 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
3424 5771 d 23 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
2787 5944 d 5 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6186 d 2 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 6186 d 7 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 6186 d 10 h jermar /trunk/kernel/ Import the AVL tree implementation from the RCU branch.  
2446 6244 d 5 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 6362 d 8 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 6368 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6379 d 1 h jermar /trunk/ (c) versus (C)  
1888 6504 d 4 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1865 6514 d 2 h jermar /trunk/kernel/ sparc64 kernel fixes  
1787 6569 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6576 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6597 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1251 6643 d 7 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 6654 d 5 h jermar /kernel/trunk/ Add bitmap ADT.  
1177 6659 d 8 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6662 d 5 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1150 6667 d 12 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.
