414 6792 d 7 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 6792 d 17 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.		  
411 6793 d 21 h jermar /SPARTAN/trunk/ Doxygen comments.  
405 6798 d 20 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6798 d 20 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
402 6800 d 6 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.		  
391 6805 d 19 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.		  
389 6806 d 5 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().		  
387 6807 d 23 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.  
386 6807 d 23 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for mutex.c.  
385 6808 d 0 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for rwlock.c.  
384 6808 d 1 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.  
383 6808 d 2 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for spinlock.c.  
382 6808 d 18 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for waitq.c.  
381 6810 d 18 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.		  
379 6812 d 3 h jermar /SPARTAN/trunk/src/mm/ Optimize buddy_system_free().
Remove special-case code from the main codepath.		  
378 6812 d 4 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 6814 d 21 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.		  
376 6815 d 0 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!		  
375 6815 d 1 h jermar /SPARTAN/trunk/src/mm/ Replace free() call with early_free() call in zone_create().
