84 6960 d 2 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.		  
81 6961 d 17 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().		  
80 6961 d 19 h vana /SPARTAN/trunk/ Fix page fault caused by dereferencing NULL pointer.  
78 6965 d 16 h jermar /SPARTAN/trunk/ IA-64 cosmetics.
Add ski_init_console() and ski_putchar() to ski.c to perform ski specific tasks.

Change the copyright string in main.c to display both copyrights on a new line.		  
77 6965 d 17 h jermar /SPARTAN/trunk/ Add %P and %p formatters to printf for printing pointers in maximum bit width.
Add %Q and %q formatters to printf for printing 64-bit integers.		  
76 6966 d 17 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 20 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6967 d 16 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.		  
72 6967 d 17 h decky /SPARTAN/trunk/ size_t usage
const qualifier
code cleanup		  
71 6967 d 17 h jermar /SPARTAN/trunk/src/main/ Declare 'HelenOS project' as the copyright holder from 2005.  
68 6967 d 18 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs		  
67 6967 d 18 h decky /SPARTAN/trunk/ typedef short bool (as logical type), defines of false and true
const qualifier for list_member()		  
66 6967 d 19 h jermar /SPARTAN/trunk/src/debug/ Correct typo - threated vs. treated.  
63 6967 d 21 h decky /SPARTAN/trunk/ const qualifier for print functions  
62 6967 d 21 h decky /SPARTAN/trunk/src/lib/ doxygen-style comments  
61 6967 d 21 h decky /SPARTAN/trunk/src/debug/ doxygen-style comments  
59 6968 d 13 h jermar /SPARTAN/trunk/ Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().		  
57 6970 d 14 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
52 6970 d 15 h vana /SPARTAN/trunk/ Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.

Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch().		  
47 6970 d 23 h jermar /SPARTAN/trunk/src/main/ Remove redundant comments.
