381 6823 d 10 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.
 
379 6824 d 20 h jermar /SPARTAN/trunk/src/mm/ Optimize buddy_system_free().
Remove special-case code from the main codepath.
 
378 6824 d 20 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 6827 d 13 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.
 
376 6827 d 16 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
375 6827 d 17 h jermar /SPARTAN/trunk/src/mm/ Replace free() call with early_free() call in zone_create().  
374 6829 d 10 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 6829 d 12 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 6831 d 14 h jermar /SPARTAN/trunk/src/main/ The more physical frames, the more memory allocated for heap.  
368 6831 d 19 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
367 6832 d 10 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.
 
364 6832 d 23 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.
 
360 6833 d 19 h jermar /SPARTAN/trunk/ Compilation fixes.
memcpy() must be declared in memstr.h
 
351 6836 d 22 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 6837 d 12 h jermar /SPARTAN/trunk/src/ Remove _qsort() as its concept is fundamentally broken.

Move lib/the.c to proc/the.c.
 
349 6837 d 12 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.

ACPI MADT parser now uses qsort() for index sorting
 
328 6842 d 22 h jermar /SPARTAN/trunk/ IA-32 can be now cross-compiled by ./build.ia32 cross.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.
