115 6923 d 3 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.		  
103 6932 d 8 h jermar /SPARTAN/trunk/ Just cleanup.  
92 6943 d 10 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.		  
90 6944 d 7 h vana /SPARTAN/trunk/ Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled.		  
84 6944 d 15 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.		  
75 6951 d 9 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6952 d 5 h vana /SPARTAN/trunk/ Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.		  
68 6952 d 7 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs		  
33 6964 d 3 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.		  
31 6967 d 11 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 6969 d 5 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.		  
22 6976 d 9 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
7 7029 d 15 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
Added architecture-independent ipi_broadcast().		  
6 7030 d 19 h jermar /SPARTAN/trunk/ shootdown vs. shutdown  
5 7031 d 5 h jermar /SPARTAN/trunk/ TLB shootdown.  
1 7034 d 10 h jermar /SPARTAN/ Initial import
