822 6676 d 1 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
814 6676 d 12 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
788 6679 d 6 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6679 d 7 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
786 6679 d 8 h bondari /kernel/trunk/ frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed
 
783 6679 d 10 h palkovsky /kernel/trunk/generic/ Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/
 
777 6680 d 6 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
762 6682 d 10 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
689 6707 d 8 h bondari /kernel/trunk/ Frame alloc test #1  
625 6731 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.
 
624 6731 d 9 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6731 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.
 
557 6739 d 11 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
552 6740 d 2 h palkovsky /kernel/trunk/ Named spinlocks  
548 6740 d 5 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6742 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6742 d 5 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 6742 d 5 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6754 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
475 6766 d 10 h jermar /SPARTAN/trunk/ Define atomic_t type.  
452 6769 d 4 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
 
430 6775 d 2 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6789 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 6790 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.
 
248 6835 d 6 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
241 6836 d 5 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
227 6836 d 10 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.
 
213 6837 d 2 h jermar /SPARTAN/trunk/ Add some comments.  
210 6837 d 3 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
195 6838 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
 
184 6838 d 15 h jermar /SPARTAN/trunk/ Add lib/the.c.
Add and deploy the_initialize() and the_copy().

Make IA-32's before_thread_runs() use SP_DELTA macro.
 
125 6884 d 2 h jermar /SPARTAN/trunk/ Huge indentation fix.  
115 6920 d 1 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.
 
111 6923 d 4 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.
 
107 6926 d 10 h decky /SPARTAN/trunk/src/ doxygen-style comments
cleanups
 
97 6935 d 12 h jermar /SPARTAN/trunk/ Add context_set() macro to support extended behaviour for architectures with more than one stack (e.g. IA-64).
Now there is one generic context_set() defined in include/context.h and one IA-64 specific defined in arch/ia64/include/context.h.
 
81 6943 d 4 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().
 
76 6948 d 4 h jermar /SPARTAN/trunk/ For each architecture, add function/macro FADDR that calculates absolute address of a function referenced by void (* f)(void).
IA-32 and MIPS gcc's use direct addressing (f == FADDR(f)) while IA-64 gcc uses indirect addressing (f != FADDR(f)).

Tweaks in IA-64 Makefile.inc to declare constant gp and main Makefile to consider ASFLAGS when compiling .s targets.
 
73 6949 d 2 h vana /SPARTAN/trunk/ Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.
 
22 6973 d 6 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.
