76 6990 d 16 h jermar /SPARTAN/trunk/ For each architecture, add function/macro FADDR that calculates absolute address of a function referenced by void (* f)(void).
IA-32 and MIPS gcc's use direct addressing (f == FADDR(f)) while IA-64 gcc uses indirect addressing (f != FADDR(f)).

Tweaks in IA-64 Makefile.inc to declare constant gp and main Makefile to consider ASFLAGS when compiling .s targets.		  
75 6990 d 18 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6991 d 14 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.		  
63 6991 d 19 h decky /SPARTAN/trunk/ const qualifier for print functions  
58 6994 d 12 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
56 6994 d 13 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
51 6994 d 16 h jermar /SPARTAN/trunk/ Small changes, fix last few wrong indentations.
TODO cleanup.

IA-64 bits.
Call main_bsp from kernel_image_start().
Prepare for IA-64 context_save and context_restore.		  
46 6994 d 22 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.		  
45 6995 d 2 h vana /SPARTAN/trunk/ Added fpu_context_t type.
IA-32's version of this type contains array of 512 bytes to be used by FXSAVE ... instructions.		  
40 6996 d 23 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
38 6999 d 18 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
34 7002 d 19 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.		  
33 7003 d 12 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.		  
32 7005 d 15 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
30 7007 d 2 h jermar /SPARTAN/trunk/arch/ia32/ Separate EBDA detection from MP Specification code. EBDA address will be needed during ACPI initialization.  
29 7007 d 19 h jermar /SPARTAN/trunk/arch/ia32/ Begin ACPI support.
ACPI support will be necessary for initialization of SMP systems with SMT (HyperThreading).		  
28 7008 d 0 h jermar /SPARTAN/trunk/ Small improvements.  
27 7008 d 14 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.		  
24 7013 d 17 h jermar /SPARTAN/trunk/ Small fixes.  
21 7016 d 19 h jermar /SPARTAN/trunk/arch/ia32/ Minor changes and cleanups of recent modifications.
