117 7083 d 5 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 7091 d 0 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 7092 d 5 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 7094 d 6 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config		  
92 7108 d 4 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 7108 d 21 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 7109 d 7 h jermar /SPARTAN/trunk/ Rename test/fpu/fp0 to test/fpu/fpu0.
(Couldn't do it in one go.)		  
87 7109 d 7 h jermar /SPARTAN/trunk/ Rename test/fp to test/fpu.  
84 7109 d 9 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 7111 d 2 h vana /SPARTAN/trunk/ Fix page fault caused by dereferencing NULL pointer.  
75 7116 d 3 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
46 7120 d 7 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 7120 d 11 h vana /SPARTAN/trunk/src/ JV's first commit :-)  
37 7125 d 9 h jermar /SPARTAN/trunk/ More IA-64 work.
IA-64 putchar() for Ski simulator.
Linker script changes.		  
35 7127 d 10 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.  
34 7128 d 4 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 7132 d 4 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 7133 d 23 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 7136 d 7 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
25 7136 d 10 h jermar /SPARTAN/trunk/src/ Fix waitq_sleep_timeout() to call before_thread_runs() when handling timeout.
