212 6890 d 0 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6890 d 0 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6890 d 10 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
207 6890 d 10 h decky /SPARTAN/trunk/ separated stack mapping  
206 6890 d 11 h palkovsky /SPARTAN/trunk/ Better types for ia32 drivers, so that they can be reused in amd64.
Build script cleanup amd64.
New code / not working yet / in amd64.		  
205 6890 d 12 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 6891 d 0 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
200 6891 d 0 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6891 d 1 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
197 6891 d 2 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6891 d 2 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 6891 d 4 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 6891 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 6891 d 12 h cejka /SPARTAN/trunk/ Small improvements in print1 test and its source code format.  
182 6891 d 13 h cejka /SPARTAN/trunk/ Test for printf added.  
181 6891 d 13 h cejka /SPARTAN/trunk/ Bugs in printf and va_arg functions repaired.  
180 6892 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 6892 d 4 h decky /SPARTAN/trunk/ frmaebuffer font  
177 6892 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.		  
174 6896 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 6897 d 10 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.		  
170 6899 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.		  
168 6901 d 0 h jermar /SPARTAN/trunk/ Add type cast to __address in vm_create().
This seems to fix the problem with userspace.

Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code.		  
167 6902 d 9 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)
