177 6849 d 2 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 6852 d 17 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.		  
169 6857 d 15 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
167 6859 d 0 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.		  
166 6860 d 18 h decky /SPARTAN/trunk/arch/ppc/ prepare for PPC console support  
163 6861 d 0 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6861 d 1 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script  
161 6863 d 2 h jermar /SPARTAN/trunk/arch/ For all relevant architectures, rename fake.s to dummy.s to better reflect the purpose of the file.
Also define global symbol called dummy.		  
160 6866 d 14 h jermar /SPARTAN/trunk/ PPC work.
Define dummy implementations of many functions in fake.s.
Define kernel_image_start in start.S.		  
159 6866 d 15 h jermar /SPARTAN/trunk/arch/ppc/include/ Fix copyright dates.  
157 6866 d 23 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
156 6867 d 2 h decky /SPARTAN/trunk/ PPC work in progress  
125 6893 d 16 h jermar /SPARTAN/trunk/ Huge indentation fix.  
103 6938 d 19 h jermar /SPARTAN/trunk/ Just cleanup.  
57 6961 d 14 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
52 6961 d 15 h vana /SPARTAN/trunk/ Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.

Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch().		  
1 7040 d 20 h jermar /SPARTAN/ Initial import
