1165 6592 d 6 h decky /kernel/trunk/arch/ set ELF format explicitly  
1164 6592 d 7 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1163 6592 d 7 h decky /kernel/trunk/arch/ fix types  
1162 6592 d 7 h decky /kernel/trunk/arch/ make the ppc ports generate proper 32b or 64b code  
1161 6592 d 7 h decky /kernel/trunk/ remove AFLAGS from C argument list  
1160 6592 d 7 h decky /kernel/trunk/ start ppc64 port
the code is currently a wild mixture of 32/64b code, will be fixed		  
1159 6592 d 8 h jermar /kernel/trunk/generic/ Replace list of all tasks with B+tree of all tasks.  
1158 6592 d 8 h jermar /kernel/trunk/generic/ Replace list of all threads with B+tree of all threads.
Add function thread_exists() for querying existence of thread.		  
1156 6592 d 9 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().		  
1154 6596 d 5 h jermar /kernel/trunk/generic/src/adt/ Fix critical bug in hash table initialization.
Only half of the table was actually allocated and initialized.		  
1153 6596 d 11 h jermar /kernel/trunk/generic/src/synch/ Because of another race condition, futex_wakeup() needs to be able to allocate and initialize the kernel futex structure too.  
1151 6596 d 12 h decky /kernel/trunk/arch/ppc32/src/mm/ ppc32: mark four first frames as unavailable  
1150 6597 d 14 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.		  
1149 6598 d 1 h jermar /kernel/trunk/generic/include/mm/ s/B+-tree/B+tree/  
1148 6598 d 1 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6598 d 1 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.		  
1145 6599 d 8 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1144 6600 d 4 h jermar /kernel/trunk/ Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list.		  
1142 6600 d 12 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.)		  
1141 6601 d 9 h palkovsky /kernel/trunk/generic/src/ipc/ Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.		  
1140 6602 d 4 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.		  
1139 6602 d 4 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6605 d 6 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().		  
1137 6605 d 10 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1136 6606 d 4 h jermar /kernel/trunk/generic/src/adt/ Try to avoid splitting full B+-tree nodes by trying left or right rotation first.
(This improved memory consumption of this algorithm by some 40% - meassured on 101-item set).		  
1135 6607 d 0 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1134 6607 d 7 h jermar /kernel/trunk/generic/src/adt/ Change B+-tree to:
- store lesser keys in a key's left subtree
- propagate the bigger of medians (if there are two medians) when splitting a node		  
1132 6608 d 4 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1126 6608 d 11 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1124 6608 d 12 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.		  
1122 6608 d 22 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.		  
1121 6609 d 2 h jermar /kernel/trunk/ Small textual changes.  
1119 6609 d 2 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.		  
1118 6609 d 2 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1117 6609 d 2 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1115 6609 d 11 h jermar /kernel/trunk/generic/src/proc/ Fix kcpulb() to change state of the migrated thread to Entering so that thread_ready() won't panic() on violated assertion.
Make print out of threads and tasks more dense again.		  
1112 6609 d 13 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).		  
1109 6610 d 1 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1108 6610 d 1 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1107 6610 d 1 h jermar /kernel/trunk/ Small atomic #include and typedef changes.
