1313 6613 d 12 h jermar /kernel/trunk/ Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar().		  
1288 6621 d 13 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1264 6625 d 12 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6629 d 8 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6632 d 12 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1224 6633 d 11 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1158 6647 d 10 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 6647 d 11 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().		  
1153 6651 d 13 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 6664 d 4 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1109 6665 d 2 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1104 6665 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 6665 d 12 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1100 6667 d 4 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 6710 d 7 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6710 d 8 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
625 6762 d 9 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 6762 d 14 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 6763 d 4 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
615 6764 d 13 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
581 6767 d 13 h palkovsky /kernel/trunk/ Small debug changes.  
557 6770 d 11 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.		  
552 6771 d 3 h palkovsky /kernel/trunk/ Named spinlocks  
534 6773 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6773 d 5 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6785 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6799 d 12 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6806 d 3 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6820 d 15 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 6821 d 1 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 6827 d 4 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6827 d 4 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
387 6836 d 7 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.  
386 6836 d 7 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for mutex.c.  
385 6836 d 8 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for rwlock.c.  
384 6836 d 9 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.

382 6837 d 2 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for waitq.c.  
223 6867 d 15 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
195 6869 d 5 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
