81 6984 d 20 h jermar /SPARTAN/trunk/ Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.

IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().

Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id().		  
76 6989 d 20 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 6989 d 23 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6990 d 19 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 0 h decky /SPARTAN/trunk/ const qualifier for print functions  
58 6993 d 16 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
56 6993 d 18 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
51 6993 d 21 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 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.		  
45 6994 d 7 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 4 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
38 6998 d 22 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
34 7002 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.		  
33 7002 d 16 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.		  
32 7004 d 20 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
30 7006 d 7 h jermar /SPARTAN/trunk/arch/ia32/ Separate EBDA detection from MP Specification code. EBDA address will be needed during ACPI initialization.  
29 7007 d 0 h jermar /SPARTAN/trunk/arch/ia32/ Begin ACPI support.
ACPI support will be necessary for initialization of SMP systems with SMT (HyperThreading).		  
28 7007 d 4 h jermar /SPARTAN/trunk/ Small improvements.  
27 7007 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.		  
24 7012 d 22 h jermar /SPARTAN/trunk/ Small fixes.
