257 6854 d 3 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.		  
251 6854 d 13 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 6854 d 19 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
245 6854 d 20 h palkovsky /SPARTAN/trunk/ Use ia32 memmap.h/memmapash.h  
243 6854 d 22 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 6854 d 23 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.		  
241 6855 d 18 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
239 6855 d 19 h vana /SPARTAN/trunk/ Missing ";" added  
238 6855 d 19 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions  
236 6855 d 20 h jermar /SPARTAN/trunk/src/ Add missing header into kinit.c.

Do not use PA2KA() on dst_ptl0.		  
235 6855 d 21 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
228 6855 d 22 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 6855 d 23 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 6855 d 23 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
223 6856 d 4 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
221 6856 d 4 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 6856 d 5 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6856 d 12 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
216 6856 d 13 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
214 6856 d 15 h vana /SPARTAN/trunk/src/
