205 6847 d 13 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
202 6848 d 0 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
200 6848 d 0 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6848 d 1 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
197 6848 d 2 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6848 d 3 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option		  
192 6848 d 5 h jermar /SPARTAN/trunk/ Dump implementation of THREAD, TASK and CPU.
Implement preemption-safe versions of THREAD, TASK and CPU using THE.
Get rid of CPU_ID_ARCH on all architectures.
Get rid of write_dr0() and read_dr0() on IA-32.
Get rid of cpu_private_data and cpu_private_data_t.		  
184 6848 d 13 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 6848 d 13 h cejka /SPARTAN/trunk/ Small improvements in print1 test and its source code format.  
182 6848 d 13 h cejka /SPARTAN/trunk/ Test for printf added.  
181 6848 d 14 h cejka /SPARTAN/trunk/ Bugs in printf and va_arg functions repaired.  
180 6849 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 6849 d 5 h decky /SPARTAN/trunk/ frmaebuffer font  
177 6849 d 11 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.		  
174 6853 d 1 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
171 6854 d 10 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.		  
170 6857 d 0 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.		  
168 6858 d 1 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 6859 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.		  
164 6861 d 3 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.
