1145 6608 d 5 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1144 6609 d 1 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 6609 d 9 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 6610 d 6 h palkovsky /kernel/trunk/generic/src/ipc/ Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.
 
1140 6611 d 1 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 6611 d 1 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6614 d 3 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 6614 d 7 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1136 6615 d 1 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 6615 d 21 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
 
1134 6616 d 4 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 6617 d 1 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1126 6617 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1124 6617 d 9 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.
 
1122 6617 d 19 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.
 
1121 6617 d 23 h jermar /kernel/trunk/ Small textual changes.  
1119 6617 d 23 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.
 
1118 6617 d 23 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1117 6617 d 23 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1115 6618 d 8 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 6618 d 9 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1109 6618 d 21 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1108 6618 d 21 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1107 6618 d 21 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1106 6618 d 22 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1104 6619 d 3 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 6619 d 7 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1102 6619 d 21 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1101 6620 d 23 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
 
1100 6620 d 23 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
 
1097 6621 d 6 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6621 d 6 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall
 
1094 6621 d 9 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1093 6621 d 22 h palkovsky /kernel/trunk/generic/src/mm/ Fix bug with refcounts in frame allocator after zone_merge. (it caused some
frames not to be coalesced).
 
1090 6622 d 0 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.
 
1088 6622 d 7 h palkovsky /kernel/trunk/generic/ More IPC stuff, added correct closing of connections from both sides.  
1087 6622 d 9 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fix MIPS32 bad paging index computation. Fixed random page faults on mips.  
1086 6622 d 21 h palkovsky /kernel/trunk/generic/ Untested better IPC functions.
* There is some bug in MIPS, unpredicatbly sometimes the thread gets mapped
different frame for stack.
 
1084 6623 d 19 h palkovsky /kernel/trunk/ Better IPC implementation with regard to locking and final cleanup.  
1083 6623 d 21 h palkovsky /kernel/trunk/generic/src/ Fixed incorrect locking in ipc.
