1142 6618 d 13 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 10 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 5 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 5 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6623 d 7 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().
 
1136 6624 d 5 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).
 
1134 6625 d 8 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
 
1121 6627 d 3 h jermar /kernel/trunk/ Small textual changes.  
1118 6627 d 3 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1117 6627 d 3 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1115 6627 d 12 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 6627 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 6628 d 1 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1108 6628 d 2 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1107 6628 d 2 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6628 d 7 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 6628 d 11 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1101 6630 d 3 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
 
1100 6630 d 3 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.
 
1093 6631 d 2 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 6631 d 4 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.
 
1088 6631 d 11 h palkovsky /kernel/trunk/generic/ More IPC stuff, added correct closing of connections from both sides.  
1086 6632 d 1 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 6632 d 23 h palkovsky /kernel/trunk/ Better IPC implementation with regard to locking and final cleanup.  
1083 6633 d 1 h palkovsky /kernel/trunk/generic/src/ Fixed incorrect locking in ipc.  
1078 6633 d 6 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1076 6633 d 11 h jermar /kernel/trunk/generic/src/mm/ Unlock address space area when returning error.  
1072 6633 d 12 h palkovsky /kernel/trunk/ Added debugger to AMD64.
Added automatic debugging of AS if it is not rewritten with zero.
Did small changes to IPC infrastructure.
 
1070 6633 d 14 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1069 6633 d 14 h cejka /kernel/trunk/ Printf correctly handle NULL pointer as parameter to %s option.  
1066 6633 d 22 h jermar /kernel/trunk/ Support for user space threads.  
1063 6634 d 0 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1062 6634 d 1 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.
 
1060 6634 d 3 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.
 
1053 6634 d 7 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1050 6634 d 8 h palkovsky /kernel/trunk/ Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized.
 
1048 6634 d 9 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.
 
1044 6634 d 11 h jermar /kernel/trunk/ Page table locking.  
1042 6634 d 11 h decky /kernel/trunk/generic/src/main/ more verbose warning  
1040 6634 d 12 h palkovsky /kernel/trunk/generic/ Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.
