189 6845 d 6 h decky /SPARTAN/trunk/arch/ppc/include/asm/ PPC assembler register names  
188 6845 d 7 h palkovsky /SPARTAN/trunk/arch/amd64/ AMD64 now can switch into long mode.
Basic page tables working.		  
187 6845 d 9 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.

186 6845 d 10 h decky /SPARTAN/trunk/arch/ppc/ add missing OpenFirmware related files  
185 6845 d 10 h decky /SPARTAN/trunk/arch/ OpenFirmware support  
184 6845 d 12 h jermar /SPARTAN/trunk/ Add lib/the.c.
Add and deploy the_initialize() and the_copy().

Make IA-32's before_thread_runs() use SP_DELTA macro.		  
183 6845 d 12 h cejka /SPARTAN/trunk/ Small improvements in print1 test and its source code format.  
182 6845 d 13 h cejka /SPARTAN/trunk/ Test for printf added.  
181 6845 d 13 h cejka /SPARTAN/trunk/ Bugs in printf and va_arg functions repaired.  
180 6846 d 2 h jermar /SPARTAN/trunk/ Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'.

Fix heap initialization to take 'heap_delta' into account.

Implement IA-64 get_stack_base().

Adjust SP_DELTA's to consider one extra word on stack.
(So that the stack pointer is within appropriate limits even on IA-64).

More #include cleanup.		  
179 6846 d 4 h decky /SPARTAN/trunk/ frmaebuffer font  
178 6846 d 8 h palkovsky /SPARTAN/trunk/arch/amd64/ Fixed linker script to include .eh_frame section.
It now boots into protected mode.		  
177 6846 d 10 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.		  
176 6847 d 1 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
175 6847 d 9 h decky /SPARTAN/trunk/contrib/ Basic PearPC configuration  
174 6850 d 1 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
173 6850 d 1 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 6851 d 10 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.		  
171 6851 d 10 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.		  
170 6853 d 23 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 6855 d 0 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
168 6855 d 0 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 6856 d 9 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 6858 d 2 h decky /SPARTAN/trunk/arch/ppc/ prepare for PPC console support  
165 6858 d 3 h palkovsky /SPARTAN/trunk/arch/amd64/boot/ Copied from ia32, bootloader can be the same.  
164 6858 d 3 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.  
163 6858 d 8 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6858 d 10 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script  
161 6860 d 11 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 6863 d 23 h jermar /SPARTAN/trunk/ PPC work.
Define dummy implementations of many functions in fake.s.
Define kernel_image_start in start.S.		  
159 6863 d 23 h jermar /SPARTAN/trunk/arch/ppc/include/ Fix copyright dates.  
158 6864 d 7 h decky /SPARTAN/trunk/src/mm/ remove forgotten comment

156 6864 d 10 h decky /SPARTAN/trunk/ PPC work in progress  
155 6866 d 0 h decky /SPARTAN/trunk/arch/powerpc/boot/ PPC preparation work (not working yet)  
154 6867 d 22 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 6867 d 23 h jermar /SPARTAN/trunk/ Add memory barriers into spinlock_*().
Implement CS_{ENTER|LEAVE}_BARRIER() for IA-32 (no-op).
