91 6954 d 18 h jermar /SPARTAN/trunk/ Rename test/fpu/fpu0 to test/fpu/fpu1.
Enhance and beautify FPU test #1.
Add pi calculation to FPU test #1.		  
88 6955 d 4 h jermar /SPARTAN/trunk/ Rename test/fpu/fp0 to test/fpu/fpu0.
(Couldn't do it in one go.)		  
87 6955 d 4 h jermar /SPARTAN/trunk/ Rename test/fp to test/fpu.  
84 6955 d 5 h vana /SPARTAN/trunk/ IA-32 FPU lazy context switching.
Doesn't work on Bochs and sometimes produces wrong results on P4.
Seems to work on VMware and PII.

Build script for IA-32 changed to build floppy images (image.bin) 1440K long.		  
80 6956 d 22 h vana /SPARTAN/trunk/ Fix page fault caused by dereferencing NULL pointer.  
75 6961 d 23 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
46 6966 d 3 h vana /SPARTAN/trunk/ Remove fpu_context pointer from context_t.
Add fpu_context statically to thread_t.
Two functions for saving and restoring FPU context on lazy switch.		  
44 6966 d 7 h vana /SPARTAN/trunk/src/ JV's first commit :-)  
37 6971 d 6 h jermar /SPARTAN/trunk/ More IA-64 work.
IA-64 putchar() for Ski simulator.
Linker script changes.		  
35 6973 d 6 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.  
34 6974 d 0 h jermar /SPARTAN/trunk/ More ACPI work.
Initial MADT table parsing.

SMP renaming and reorganization to reflect there are more ways to bring SMP up.		  
31 6978 d 1 h jermar /SPARTAN/trunk/ Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.		  
27 6979 d 19 h jermar /SPARTAN/trunk/ APIC changes and fixes.
Be more robust during MP configuration.

Do not use APIC ID as CPU_ID_ARCH anymore.
Changing APIC ID's is not a good idea.
Use dr0 register instead.		  
26 6982 d 3 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
25 6982 d 6 h jermar /SPARTAN/trunk/src/ Fix waitq_sleep_timeout() to call before_thread_runs() when handling timeout.  
22 6986 d 23 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
19 6993 d 21 h jermar /SPARTAN/trunk/ Re-enable tests and fix include paths' in them.  
16 6994 d 0 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.		  
3 7044 d 23 h jermar /SPARTAN/trunk/src/ Minor change.  
2 7044 d 23 h jermar /SPARTAN/trunk/src/ Add ia64 and amd64 to config Makefile.
