378 6816 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.
Add some assertions.		  
377 6819 d 4 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.		  
376 6819 d 8 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!		  
375 6819 d 8 h jermar /SPARTAN/trunk/src/mm/ Replace free() call with early_free() call in zone_create().  
374 6821 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 6821 d 4 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.		  
369 6823 d 5 h jermar /SPARTAN/trunk/src/main/ The more physical frames, the more memory allocated for heap.  
368 6823 d 11 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
367 6824 d 2 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.		  
364 6824 d 14 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.		  
360 6825 d 10 h jermar /SPARTAN/trunk/ Compilation fixes.
memcpy() must be declared in memstr.h		  
351 6828 d 14 h jermar /SPARTAN/trunk/src/lib/ Ok. The idea of _qsort() was not broken at all.
Revert the changes and make _qsort() call _qsort() rather than qsort() so that the idea has effect.
Add _bubblesort() to optimize number of allocations when bubblesort algorithm is invoked from _qsort().
Add doxygen-style comments.		  
350 6829 d 3 h jermar /SPARTAN/trunk/src/ Remove _qsort() as its concept is fundamentally broken.

Move lib/the.c to proc/the.c.		  
349 6829 d 3 h jermar /SPARTAN/trunk/ Optimize sorting functions so that malloc() and free() is called only for e_size > EBUFSIZE.
Smaller buffers are allocated directly on the stack.

Some copyright holder fixes on some files written by Ondrej Palkovsky.		  
341 6832 d 11 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
338 6833 d 9 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.		  
336 6833 d 11 h bondari /SPARTAN/trunk/src/lib/ minor  
335 6833 d 11 h bondari /SPARTAN/trunk/src/lib/ More effective memory allocations with help of qsort wrapper method  
333 6833 d 12 h bondari /SPARTAN/trunk/src/lib/ Copyright notice and proper tabs  
332 6833 d 12 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.
