1146 6617 d 6 h decky /boot/trunk/arch/ppc32/loader/ add instruction cache flush
align framebuffer on 128K boundary
change OFW calling method
make OFW code more compatible
 
1145 6617 d 6 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1144 6618 d 2 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.
 
1143 6618 d 6 h palkovsky /uspace/trunk/libc/ Added support for multithreading (using futexes) into malloc.  
1142 6618 d 10 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 6619 d 7 h palkovsky /kernel/trunk/generic/src/ipc/ Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.
 
1140 6620 d 2 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 6620 d 2 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6623 d 4 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 6623 d 8 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1136 6624 d 2 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 6624 d 22 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
 
1134 6625 d 5 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 6626 d 0 h decky /boot/trunk/arch/ppc32/loader/ ofw uses \r\n as newline  
1132 6626 d 2 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1131 6626 d 2 h decky /boot/trunk/arch/ppc32/loader/ kernel boot API change  
1130 6626 d 3 h decky /boot/trunk/arch/ppc32/loader/ extend boot info  
1129 6626 d 7 h palkovsky /uspace/trunk/ Completed support for TLS in GCC (modifier __thread) for ia32,amd64,ia64 and mips.  
1128 6626 d 7 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 6626 d 9 h palkovsky /uspace/trunk/ Correct dependencies creation.  
1126 6626 d 9 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1125 6626 d 10 h jermar /uspace/trunk/ TLS and pseudo thread support for ia64.  
1124 6626 d 10 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.
 
1123 6626 d 20 h palkovsky /uspace/trunk/libc/arch/mips32/ Changed MIPS to compile as PIC code.  
1122 6626 d 20 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.
 
1121 6627 d 0 h jermar /kernel/trunk/ Small textual changes.  
1120 6627 d 0 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 6627 d 0 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.
 
1118 6627 d 0 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1117 6627 d 0 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1116 6627 d 0 h jermar /uspace/trunk/libc/ Improved futexes for uspace.
Please review.
 
1115 6627 d 9 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 6627 d 10 h jermar /uspace/trunk/libc/generic/ Fix futexes to correctly wake sleeping threads.  
1113 6627 d 10 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 6627 d 11 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1111 6627 d 23 h jermar /uspace/trunk/ Basic futex support for userspace.  
1110 6627 d 23 h jermar /uspace/trunk/libc/ Port atomic operations to uspace.  
1109 6627 d 23 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1108 6627 d 23 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1107 6627 d 23 h jermar /kernel/trunk/ Small atomic #include and typedef changes.
