257 6846 d 16 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.		  
256 6846 d 16 h decky /SPARTAN/trunk/arch/mips/include/ fix MIPS build error  
255 6846 d 16 h jermar /SPARTAN/trunk/contrib/ Break contrib/ directory into contrib/conf/ and contrib/toolchain.  
254 6846 d 16 h decky /SPARTAN/trunk/arch/ppc/ fix stupid assembler bugs in cpu_priority_* (PPC)  
253 6846 d 17 h jermar /SPARTAN/trunk/arch/ Implement PPC's get_stack_base().

Comment AMD64's get_stack_base().		  
252 6846 d 18 h palkovsky /SPARTAN/trunk/arch/amd64/ Added volatile to inb/outb, so that it does not optimeze
lot of things out anymore.
Working delay loop.		  
251 6847 d 1 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.		  
250 6847 d 6 h jermar /SPARTAN/trunk/arch/ppc/src/ Add missing semicolon.  
249 6847 d 7 h vana /SPARTAN/trunk/arch/ia64/src/ Serialization of psr write  
248 6847 d 8 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
247 6847 d 8 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Fix nasty bug in arch/mm/frame.c.
frame_region_not_free() takes address as its second argument, not size.		  
246 6847 d 8 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)  
245 6847 d 9 h palkovsky /SPARTAN/trunk/ Use ia32 memmap.h/memmapash.h  
244 6847 d 10 h decky /SPARTAN/trunk/arch/ia32/src/ temporarily fix IA-32 boot bug  
243 6847 d 10 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 6847 d 11 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.		  
241 6848 d 6 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
240 6848 d 7 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad register assignment in atomic.h.
Added -msoft-float so that it does not call coprocessor and it works withou doubles.
Removed undefined symbol from tlb.c. Unfortunately
mips linker does not report missing symbols.		  
239 6848 d 7 h vana /SPARTAN/trunk/ Missing ";" added  
238 6848 d 8 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions  
237 6848 d 8 h palkovsky /SPARTAN/trunk/arch/mips/src/ Fixed missing semicolon;  
236 6848 d 9 h jermar /SPARTAN/trunk/src/ Add missing header into kinit.c.

Do not use PA2KA() on dst_ptl0.		  
235 6848 d 9 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
234 6848 d 9 h decky /SPARTAN/trunk/contrib/ VMWare sample configuration  
233 6848 d 9 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Do not use the unmapped addresses of e820 kernel structures.
Use PA2KA() to access the e820 counter and memtable.		  
232 6848 d 10 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
231 6848 d 10 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Better coding style  
230 6848 d 10 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 6848 d 10 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Removed mapping of bottom 2GB to kernel space.  
228 6848 d 10 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 6848 d 11 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 6848 d 11 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
225 6848 d 14 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 6848 d 16 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
223 6848 d 16 h jermar /SPARTAN/trunk/ Preemption work.

221 6848 d 17 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).
