235 6914 d 17 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
228 6914 d 19 h cejka /SPARTAN/trunk/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
227 6914 d 19 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.		  
226 6914 d 19 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
223 6915 d 0 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
221 6915 d 1 h jermar /SPARTAN/trunk/ Preemption work.
Define PREEMPTION_DISABLED macro.
This macro determines the level of preemptivity (0 = preemption enabled, THE->preemption_disabled = no preemption inside spinlock, 1 = preemption disabled).
Reformulate preemption code in clock.c to consider PREEMPTION_DISABLED.		  
220 6915 d 1 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6915 d 8 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
216 6915 d 10 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
214 6915 d 11 h vana /SPARTAN/trunk/src/  
213 6915 d 12 h jermar /SPARTAN/trunk/ Add some comments.  
212 6915 d 12 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6915 d 12 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6915 d 21 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
207 6915 d 22 h decky /SPARTAN/trunk/ separated stack mapping  
206 6915 d 23 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 6916 d 0 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 6916 d 11 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
200 6916 d 11 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6916 d 12 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
197 6916 d 13 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6916 d 14 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 6916 d 16 h jermar /SPARTAN/trunk/ Dump implementation of THREAD, TASK and CPU.

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 6917 d 0 h jermar /SPARTAN/trunk/ Add lib/the.c.
Add and deploy the_initialize() and the_copy().

182 6917 d 0 h cejka /SPARTAN/trunk/ Test for printf added.  
181 6917 d 1 h cejka /SPARTAN/trunk/ Bugs in printf and va_arg functions repaired.  
180 6917 d 13 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.

177 6917 d 22 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 6921 d 12 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
171 6922 d 21 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.		  
170 6925 d 11 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 6926 d 12 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 6927 d 20 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.
