228 6844 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 6844 d 20 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 6844 d 20 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
223 6845 d 1 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
221 6845 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 6845 d 2 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6845 d 9 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
216 6845 d 10 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
214 6845 d 12 h vana /SPARTAN/trunk/src/  
213 6845 d 12 h jermar /SPARTAN/trunk/ Add some comments.  
212 6845 d 12 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6845 d 12 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6845 d 22 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
207 6845 d 22 h decky /SPARTAN/trunk/ separated stack mapping  
206 6845 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 6846 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 6846 d 12 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
200 6846 d 12 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6846 d 13 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
197 6846 d 14 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64
