381 6852 d 3 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.

378 6853 d 12 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.

374 6858 d 2 h jermar /SPARTAN/trunk/ Revert previous change in frame_t as it broke IA-64.
(Most likely some alignment problem.)

Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively.
Define new macros malloc() and free(). They are to be replaced by real functions some day.
 
373 6858 d 5 h jermar /SPARTAN/trunk/ Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant.
 
368 6860 d 12 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
367 6861 d 3 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.
 
366 6861 d 3 h jermar /SPARTAN/trunk/include/ Add zone pointer to frame_t.
This will be essential for fast frame_free().

Rename frame_zone_t to zone_t.

Declare frame and zone functions to be implemented.
 
365 6861 d 4 h jermar /SPARTAN/trunk/ Replace #define's in list.h with type-safe inlines.

Update mips32 documentation.
 
362 6862 d 5 h bondari /SPARTAN/trunk/include/ Some junk code removed  
361 6862 d 5 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
360 6862 d 11 h jermar /SPARTAN/trunk/ Compilation fixes.
memcpy() must be declared in memstr.h
 
358 6863 d 4 h bondari /SPARTAN/trunk/ built-in memcpy is not used anymore on IA-32.
IA-32 memcpy is now fast and inline.
 
355 6863 d 10 h jermar /SPARTAN/trunk/include/mm/ Add 'base' attribute to frame_zone_t structure.  
354 6863 d 11 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.

Add some comments.
 
338 6870 d 10 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.
 
331 6870 d 13 h bondari /SPARTAN/trunk/ Generic quicksort and bubble sort implementation.
ACPI MADT parser now uses qsort() for index sorting
 
309 6875 d 15 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
292 6877 d 2 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().
 
270 6878 d 8 h palkovsky /SPARTAN/trunk/ Symbols now include filename  
268 6878 d 9 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
265 6878 d 12 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
 
264 6878 d 12 h cejka /SPARTAN/trunk/ E option in printf added.  
251 6879 d 1 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.
 
228 6880 d 10 h cejka /SPARTAN/trunk/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.
 
227 6880 d 11 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Instrument spinlock functions with preemption_disable() and preemption_enable() calls.
 
221 6880 d 17 h jermar /SPARTAN/trunk/ Preemption work.
Define PREEMPTION_DISABLED macro.
This macro determines the level of preemptivity (0 = preemption enabled, THE->preemption_disabled = no preemption inside spinlock, 1 = preemption disabled).
Reformulate preemption code in clock.c to consider PREEMPTION_DISABLED.
 
210 6881 d 4 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files

205 6881 d 15 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
