413 6785 d 5 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.		  
410 6786 d 9 h jermar /SPARTAN/trunk/ Doxygen-style comments.  
177 6834 d 16 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.		  
173 6838 d 7 h jermar /SPARTAN/trunk/ Preparations for weaker preemption model.
Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy.		  
125 6879 d 6 h jermar /SPARTAN/trunk/ Huge indentation fix.  
73 6944 d 6 h vana /SPARTAN/trunk/ Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.		  
57 6947 d 4 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
56 6947 d 5 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
46 6947 d 14 h vana /SPARTAN/trunk/ Remove fpu_context pointer from context_t.
Add fpu_context statically to thread_t.
Two functions for saving and restoring FPU context on lazy switch.		  
1 7026 d 11 h jermar /SPARTAN/ Initial import
