1140 6656 d 14 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 6656 d 14 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6659 d 15 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 6659 d 19 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1136 6660 d 13 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 6661 d 10 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
 
1134 6661 d 17 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
 
1133 6662 d 12 h decky /boot/trunk/arch/ppc32/loader/ ofw uses \r\n as newline  
1132 6662 d 13 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1131 6662 d 13 h decky /boot/trunk/arch/ppc32/loader/ kernel boot API change  
1130 6662 d 14 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1129 6662 d 18 h palkovsky /uspace/trunk/ Completed support for TLS in GCC (modifier __thread) for ia32,amd64,ia64 and mips.  
1128 6662 d 18 h jermar /uspace/trunk/ Improve comments in psthread.c
Rename pt->list to pt->link.
Rename ps_preempt() to psthread_schedule_next().
Rename ps_join() to psthread_join().
 
1127 6662 d 20 h palkovsky /uspace/trunk/ Correct dependencies creation.  
1126 6662 d 20 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1125 6662 d 21 h jermar /uspace/trunk/ TLS and pseudo thread support for ia64.  
1124 6662 d 21 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.
 
1123 6663 d 8 h palkovsky /uspace/trunk/libc/arch/mips32/ Changed MIPS to compile as PIC code.  
1122 6663 d 8 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.
 
1121 6663 d 11 h jermar /kernel/trunk/ Small textual changes.  
1120 6663 d 11 h palkovsky /uspace/trunk/libc/arch/ Added missing ia32 files.
Renamed __entry to __start in mips, which is standard in gcc standard
linking scripts.
 
1119 6663 d 11 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.
 
1118 6663 d 11 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1117 6663 d 11 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1116 6663 d 11 h jermar /uspace/trunk/libc/ Improved futexes for uspace.
Please review.
 
1115 6663 d 21 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.
 
1114 6663 d 21 h jermar /uspace/trunk/libc/generic/ Fix futexes to correctly wake sleeping threads.  
1113 6663 d 22 h palkovsky /uspace/trunk/ Added symbolic links 'libarch','libadt','libipc' into libc/include,
so that it can be easily used from anywhere.
Renamed thread_main to __thread_main.
Allowed MIPS to compile with -O0.
Added non-preemptible threads support (not yet secured by futexes).
Added simple way to hold Thread Local Storage. Support for compiler
will be added later.
This update breaks IA64 uspace.

There is some forgotten spinlock_lock() in futexes, amd64 gets locked
in the secod uspace thread probably with preemption disabled.
 
1112 6663 d 22 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1111 6664 d 10 h jermar /uspace/trunk/ Basic futex support for userspace.  
1110 6664 d 10 h jermar /uspace/trunk/libc/ Port atomic operations to uspace.  
1109 6664 d 10 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1108 6664 d 10 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1107 6664 d 10 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1106 6664 d 10 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1105 6664 d 10 h jermar /uspace/trunk/libc/arch/mips32/ Fix mips32 linker script.
Add .scommon input section.
Add .got section and define _gp symbol.
Use this symbol to initialize gp register (r28).
 
1104 6664 d 15 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.
 
1103 6664 d 19 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1102 6665 d 10 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1101 6666 d 12 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
