174 6845 d 16 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
173 6845 d 16 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.		  
172 6847 d 0 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.		  
170 6849 d 14 h jermar /SPARTAN/trunk/ Add comment to scheduler.c explaining the reason behind saving CPU priority of preempted thread.

Remove two unnecessary cpu_priority_high() calls.		  
169 6850 d 14 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
168 6850 d 15 h jermar /SPARTAN/trunk/ Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.

Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code.		  
167 6852 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 6853 d 17 h decky /SPARTAN/trunk/arch/ppc/ prepare for PPC console support  
165 6853 d 18 h palkovsky /SPARTAN/trunk/arch/amd64/boot/ Copied from ia32, bootloader can be the same.  
164 6853 d 18 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.  
163 6853 d 23 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6854 d 1 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script  
161 6856 d 1 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 6859 d 13 h jermar /SPARTAN/trunk/ PPC work.
Define dummy implementations of many functions in fake.s.
Define kernel_image_start in start.S.		  
159 6859 d 14 h jermar /SPARTAN/trunk/arch/ppc/include/ Fix copyright dates.  
157 6859 d 22 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
156 6860 d 1 h decky /SPARTAN/trunk/ PPC work in progress  
155 6861 d 15 h decky /SPARTAN/trunk/arch/powerpc/boot/ PPC preparation work (not working yet)  
154 6863 d 13 h jermar /SPARTAN/trunk/ Update TODO.
Explicitly mark places of interest related to memory barriers on non-IA-32 architectures with TODO remarks so that they don't get forgotten.		  
153 6863 d 14 h jermar /SPARTAN/trunk/ Add memory barriers into spinlock_*().
Implement CS_{ENTER|LEAVE}_BARRIER() for IA-32 (no-op).
Provide incomplete CS_{ENTER|LEAVE}_BARRIER() macros for IA-64 and MIPS as well.

Small changes here and there.
