2131 6446 d 7 h decky /branches/ add development branches  
2082 6507 d 11 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6512 d 4 h jermar /trunk/ (c) versus (C)  
1888 6637 d 7 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6702 d 6 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1769 6712 d 2 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.
 
1702 6730 d 10 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1107 6813 d 2 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6813 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.
 
1024 6820 d 5 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
627 6910 d 7 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 6910 d 8 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.
 
534 6921 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6921 d 5 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6933 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6941 d 4 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.
 
477 6944 d 10 h vana /SPARTAN/trunk/ Atomic inc & dec functions synchronized on all ia32,ia64 and mips platforms. Now there are 3 versions which returns no value, new value and old value och changed variable.  
475 6945 d 10 h jermar /SPARTAN/trunk/ Define atomic_t type.  
341 7004 d 10 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
240 7015 d 6 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad register assignment in atomic.h.
Added -msoft-float so that it does not call coprocessor and it works withou doubles.
Removed undefined symbol from tlb.c. Unfortunately
mips linker does not report missing symbols.
