1136 6794 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).
 
1134 6795 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
 
1121 6797 d 2 h jermar /kernel/trunk/ Small textual changes.  
1118 6797 d 2 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1117 6797 d 2 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1115 6797 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 6797 d 12 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1109 6798 d 0 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1108 6798 d 0 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1104 6798 d 6 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 6798 d 10 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1101 6800 d 2 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
 
1100 6800 d 2 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 6801 d 1 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 6801 d 3 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.
 
1088 6801 d 10 h palkovsky /kernel/trunk/generic/ More IPC stuff, added correct closing of connections from both sides.  
1086 6802 d 0 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 6802 d 22 h palkovsky /kernel/trunk/ Better IPC implementation with regard to locking and final cleanup.  
1083 6803 d 0 h palkovsky /kernel/trunk/generic/src/ Fixed incorrect locking in ipc.  
1078 6803 d 5 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
