625 6764 d 1 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.
 
624 6764 d 1 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6764 d 6 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.
 
557 6772 d 3 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
552 6772 d 19 h palkovsky /kernel/trunk/ Named spinlocks  
548 6772 d 21 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6774 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6774 d 21 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)
 
532 6774 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6787 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6794 d 21 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 6799 d 3 h jermar /SPARTAN/trunk/ Define atomic_t type.  
458 6801 d 4 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6801 d 21 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
 
430 6807 d 19 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6822 d 7 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 6822 d 17 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.
 
404 6828 d 20 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
391 6835 d 19 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
 
378 6842 d 4 h jermar /SPARTAN/trunk/ Redeclare eraly_malloc() with __attribute__ ((malloc)) to improve optimizations.

Reorganize #include's in scheduler.c.

Buddy system improvements.
Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced.
Add some assertions.
 
350 6854 d 19 h jermar /SPARTAN/trunk/src/ Remove _qsort() as its concept is fundamentally broken.

Move lib/the.c to proc/the.c.
 
309 6864 d 7 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
258 6867 d 7 h palkovsky /SPARTAN/trunk/src/proc/ Fixed retyping, so that it compiles with gcc 4.0.2  
248 6867 d 23 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
241 6868 d 21 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
227 6869 d 2 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.
 
214 6869 d 19 h vana /SPARTAN/trunk/src/  
213 6869 d 19 h jermar /SPARTAN/trunk/ Add some comments.  
212 6869 d 19 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6869 d 19 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
198 6870 d 19 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

195 6870 d 21 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.

Indentation fixes and small changes here and there.
