99 6953 d 3 h jermar /SPARTAN/trunk/ Replace "THREAD->cpu" with "CPU" in scheduler().

Add trailing '\n' to memmap.h
Fix some translations.
Relpace one Czech sentence with its English translation.		  
98 6953 d 20 h cejka /SPARTAN/trunk/arch/ia32/ first version of e820 memmap  
95 6955 d 1 h cejka /SPARTAN/trunk/arch/ia32/ Started memory map support.  
92 6958 d 18 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.		  
84 6960 d 0 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.		  
82 6961 d 13 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add the rest of branch registers to context_t.
Add predicate registers to context_t.
Modify context_save()/context_restore() to save/restore branch registers and predicate registers.
Change SP_DELTA to 0 since both context_save() and context_restore() are leaf procedures and as such don't use the scratch area.
Change pri_t to be __u64 instead of __u32.		  
81 6961 d 15 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 6966 d 15 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 6966 d 17 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6967 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 6967 d 18 h decky /SPARTAN/trunk/ const qualifier for print functions  
58 6970 d 11 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
56 6970 d 12 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
51 6970 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 6970 d 21 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 6971 d 1 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 6972 d 23 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
38 6975 d 17 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
34 6978 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 6979 d 11 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.
