850 6831 d 1 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
692 6871 d 5 h bondari /kernel/trunk/ Frame allocation test #2  
627 6895 d 6 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.
 
625 6895 d 7 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 6895 d 12 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.
 
534 6906 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6906 d 3 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6918 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6926 d 3 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
475 6930 d 9 h jermar /SPARTAN/trunk/ Define atomic_t type.  
413 6953 d 23 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.
 
263 6998 d 10 h palkovsky /SPARTAN/trunk/test/synch/rwlock2/ Bad prototype  
225 7000 d 11 h jermar /SPARTAN/trunk/test/synch/rwlock4/ Revert the change in rwlock #4 test that added cpu_priority_high() and cpu_priority_restore() to random().
It is no longer necessary because spinlock disables preemption at least.
 
205 7001 d 13 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().
 
171 7008 d 10 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.
 
119 7064 d 2 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.
 
111 7087 d 3 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.
 
81 7107 d 2 h jermar /SPARTAN/trunk/ Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.

IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().

Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id().
 
19 7144 d 3 h jermar /SPARTAN/trunk/ Re-enable tests and fix include paths' in them.  
15 7145 d 4 h jermar /SPARTAN/trunk/ Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.
