232 6851 d 23 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
231 6852 d 0 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Better coding style  
230 6852 d 0 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
229 6852 d 0 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Removed mapping of bottom 2GB to kernel space.  
228 6852 d 0 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 6852 d 1 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 6852 d 1 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
225 6852 d 4 h jermar /SPARTAN/trunk/test/synch/rwlock4/ Revert the change in rwlock #4 test that added cpu_priority_high() and cpu_priority_restore() to random().
It is no longer necessary because spinlock disables preemption at least.		  
224 6852 d 6 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
223 6852 d 6 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
222 6852 d 6 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
221 6852 d 6 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 6852 d 7 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6852 d 14 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
218 6852 d 14 h decky /SPARTAN/trunk/arch/ppc/ update PPC for new hardcoded_* method  
217 6852 d 14 h palkovsky /SPARTAN/trunk/arch/ia32/ Bugfix.  
216 6852 d 15 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
215 6852 d 17 h jermar /SPARTAN/trunk/contrib/ Add two more emulator config files.  
214 6852 d 17 h vana /SPARTAN/trunk/src/  
213 6852 d 17 h jermar /SPARTAN/trunk/ Add some comments.
