1414 6580 d 18 h jermar /kernel/trunk/generic/src/synch/ Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments.		  
1375 6586 d 15 h jermar /kernel/trunk/generic/ Fix race in condition variables.  
1323 6591 d 18 h jermar /kernel/trunk/ Increase "timeout" for debugging spinlock so that false positive
deadlock reports are suppressed on real hardware.

Also add one HT configuration to hardware compatibility list.		  
1313 6592 d 14 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 6600 d 15 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 6604 d 15 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6608 d 10 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6611 d 14 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1224 6612 d 13 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1158 6626 d 12 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 6626 d 13 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().		  
1153 6630 d 15 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 6643 d 6 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1109 6644 d 5 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1104 6644 d 10 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 6644 d 14 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1100 6646 d 7 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 6689 d 9 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6689 d 10 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
625 6741 d 11 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 6741 d 17 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 6742 d 7 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
615 6743 d 16 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
581 6746 d 15 h palkovsky /kernel/trunk/ Small debug changes.  
557 6749 d 14 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.		  
552 6750 d 5 h palkovsky /kernel/trunk/ Named spinlocks  
534 6752 d 7 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6752 d 8 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6764 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6778 d 15 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6785 d 5 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6799 d 18 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 6800 d 4 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 6806 d 6 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6806 d 7 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
387 6815 d 9 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.  
386 6815 d 10 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for mutex.c.  
385 6815 d 10 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for rwlock.c.  
384 6815 d 11 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.  
383 6815 d 12 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for spinlock.c.
