81 6950 d 16 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 6950 d 18 h vana /SPARTAN/trunk/ Fix page fault caused by dereferencing NULL pointer.  
79 6954 d 15 h jermar /SPARTAN/trunk/arch/ia64/src/ski/ doxygen-style comments  
78 6954 d 15 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.		  
76 6955 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 6955 d 19 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
74 6956 d 15 h jermar /SPARTAN/trunk/arch/ia64/src/ More of IA-64 initialization.  
73 6956 d 15 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 6956 d 17 h decky /SPARTAN/trunk/ size_t usage
const qualifier
code cleanup		  
68 6956 d 17 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs		  
65 6956 d 18 h decky /SPARTAN/trunk/arch/ia32/ doxygen-style comments  
63 6956 d 20 h decky /SPARTAN/trunk/ const qualifier for print functions  
60 6956 d 23 h jermar /SPARTAN/trunk/arch/ia64/ IA-64 work.
Give up attempts to persuade ld to patch the kernel image with proper hardcoded lenghts and addresses.
Add special sections and calculate the numbers manually.
Fix wrong order of operands in sub instructions in memcpy() implementation.		  
59 6957 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().		  
58 6959 d 13 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
57 6959 d 13 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
56 6959 d 14 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
55 6959 d 14 h jermar /SPARTAN/trunk/arch/ia64/src/ Add missing context.S.  
54 6959 d 14 h jermar /SPARTAN/trunk/arch/ Add missing '\' to Makefile.inc
Remove leading '_' from before_thread_runs_arch() in fake.s		  
52 6959 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().
