251 6851 d 20 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.		  
248 6852 d 3 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
245 6852 d 4 h palkovsky /SPARTAN/trunk/ Use ia32 memmap.h/memmapash.h  
243 6852 d 5 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 6852 d 7 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.		  
241 6853 d 1 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
239 6853 d 2 h vana /SPARTAN/trunk/ Missing ";" added  
238 6853 d 3 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions  
236 6853 d 4 h jermar /SPARTAN/trunk/src/ Add missing header into kinit.c.

Do not use PA2KA() on dst_ptl0.		  
235 6853 d 4 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
228 6853 d 6 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 6853 d 6 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 6853 d 6 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
223 6853 d 11 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
221 6853 d 12 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 6853 d 12 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6853 d 19 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
216 6853 d 21 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
214 6853 d 22 h vana /SPARTAN/trunk/src/  
213 6853 d 23 h jermar /SPARTAN/trunk/ Add some comments.
