243 6884 d 19 h palkovsky /SPARTAN/trunk/ Resolved mapping of e820 boot area, so that it can be accessed as
e820table from 32-bit mode and e820table_boot from real mode.
 
242 6884 d 20 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
241 6885 d 15 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
239 6885 d 16 h vana /SPARTAN/trunk/ Missing ";" added  
238 6885 d 16 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions  
236 6885 d 17 h jermar /SPARTAN/trunk/src/ Add missing header into kinit.c.

Do not use PA2KA() on dst_ptl0.
 
235 6885 d 17 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
228 6885 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 6885 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 6885 d 19 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.
 
223 6886 d 1 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.
 
221 6886 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 6886 d 2 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6886 d 9 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.
 
216 6886 d 10 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
214 6886 d 12 h vana /SPARTAN/trunk/src/  
213 6886 d 12 h jermar /SPARTAN/trunk/ Add some comments.  
212 6886 d 12 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6886 d 12 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6886 d 21 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
207 6886 d 22 h decky /SPARTAN/trunk/ separated stack mapping  
206 6886 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 6887 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 6887 d 12 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
200 6887 d 12 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6887 d 12 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.
 
197 6887 d 14 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6887 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 6887 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 6888 d 0 h jermar /SPARTAN/trunk/ Add lib/the.c.
Add and deploy the_initialize() and the_copy().

182 6888 d 1 h cejka /SPARTAN/trunk/ Test for printf added.  
181 6888 d 1 h cejka /SPARTAN/trunk/ Bugs in printf and va_arg functions repaired.  
180 6888 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.

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 6892 d 13 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.
 
171 6893 d 22 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

168 6897 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.
