374 6871 d 21 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 6871 d 23 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 6874 d 6 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
367 6874 d 21 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.
 
366 6874 d 22 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 6874 d 23 h jermar /SPARTAN/trunk/ Replace #define's in list.h with type-safe inlines.

Update mips32 documentation.
 
362 6875 d 23 h bondari /SPARTAN/trunk/include/ Some junk code removed  
361 6875 d 23 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
360 6876 d 6 h jermar /SPARTAN/trunk/ Compilation fixes.
memcpy() must be declared in memstr.h
 
358 6876 d 22 h bondari /SPARTAN/trunk/ built-in memcpy is not used anymore on IA-32.
IA-32 memcpy is now fast and inline.
 
355 6877 d 5 h jermar /SPARTAN/trunk/include/mm/ Add 'base' attribute to frame_zone_t structure.  
354 6877 d 5 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.

Add some comments.
 
338 6884 d 4 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.
 
331 6884 d 7 h bondari /SPARTAN/trunk/ Generic quicksort and bubble sort implementation.
