136 6880 d 4 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.  
135 6880 d 5 h jermar /SPARTAN/trunk/ Fix setters of page table attributes for both IA-32 and MIPS.  
119 6900 d 22 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.		  
117 6916 d 3 h jermar /SPARTAN/trunk/ Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.

Tiny changes here and there.		  
112 6923 d 22 h jermar /SPARTAN/trunk/ Define two placeholder functions for atomic_inc and atomic_dec on IA-64.

Add Ondrej Palkovsky to doc/AUTHORS.

Tweaks in IA-32 low level code to bring SMP back to life. (SMP still broken)		  
110 6925 d 4 h jermar /SPARTAN/trunk/ SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.

MIPS.
Move msim dprinter device to 0xB0000000.
This address is from kseg1 (unmapped, uncached) segment.		  
108 6927 d 4 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config		  
92 6941 d 2 h jermar /SPARTAN/trunk/ FPU work.
FPU code cleanup, add/fix copyright notices where needed.
Fix PI calculation to use double n instead of int n.
Make FPU test #1 even more stressing.

Re-enable O3 again.
Revert Makefile.config not to compile in any tests.		  
91 6941 d 20 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 6942 d 5 h jermar /SPARTAN/trunk/ Rename test/fpu/fp0 to test/fpu/fpu0.
(Couldn't do it in one go.)		  
87 6942 d 5 h jermar /SPARTAN/trunk/ Rename test/fp to test/fpu.  
84 6942 d 7 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 6944 d 0 h vana /SPARTAN/trunk/ Fix page fault caused by dereferencing NULL pointer.  
75 6949 d 1 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
46 6953 d 5 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 6953 d 9 h vana /SPARTAN/trunk/src/ JV's first commit :-)  
37 6958 d 7 h jermar /SPARTAN/trunk/ More IA-64 work.
IA-64 putchar() for Ski simulator.
Linker script changes.		  
35 6960 d 8 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.  
34 6961 d 2 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 6965 d 3 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.
