1248 6766 d 4 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6769 d 8 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1224 6770 d 6 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1158 6784 d 6 h jermar /kernel/trunk/generic/ Replace list of all threads with B+tree of all threads.
Add function thread_exists() for querying existence of thread.		  
1156 6784 d 7 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().		  
1153 6788 d 9 h jermar /kernel/trunk/generic/src/synch/ Because of another race condition, futex_wakeup() needs to be able to allocate and initialize the kernel futex structure too.  
1117 6801 d 0 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1109 6801 d 22 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1104 6802 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 6802 d 8 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1100 6804 d 0 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.		  
788 6847 d 3 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6847 d 4 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
625 6899 d 5 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.		  
623 6899 d 10 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
622 6900 d 0 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
615 6901 d 9 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
581 6904 d 9 h palkovsky /kernel/trunk/ Small debug changes.  
557 6907 d 7 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.		  
552 6907 d 23 h palkovsky /kernel/trunk/ Named spinlocks  
534 6910 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6910 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6922 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6936 d 8 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6942 d 23 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6957 d 11 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
413 6957 d 21 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.		  
405 6964 d 0 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6964 d 0 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
387 6973 d 3 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.  
386 6973 d 3 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for mutex.c.  
385 6973 d 4 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for rwlock.c.  
384 6973 d 5 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.  
383 6973 d 6 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for spinlock.c.  
382 6973 d 22 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for waitq.c.  
223 7004 d 11 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
195 7006 d 1 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option		  
153 7028 d 22 h jermar /SPARTAN/trunk/ Add memory barriers into spinlock_*().
Implement CS_{ENTER|LEAVE}_BARRIER() for IA-32 (no-op).
Provide incomplete CS_{ENTER|LEAVE}_BARRIER() macros for IA-64 and MIPS as well.

Small changes here and there.		  
115 7087 d 21 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.		  
111 7091 d 1 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.
