90 6992 d 0 h vana /SPARTAN/trunk/ Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled.		  
85 6992 d 8 h vana /SPARTAN/trunk/arch/ia32/boot/ IA-32 boot Makefile bugfix.
Previous version did not take 512B of boot sector code into account and produced wrong image.bin.		  
84 6992 d 9 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 6993 d 22 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 6994 d 0 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 6994 d 2 h vana /SPARTAN/trunk/ Fix page fault caused by dereferencing NULL pointer.  
76 6999 d 0 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 6999 d 3 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6999 d 23 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 7000 d 1 h decky /SPARTAN/trunk/ size_t usage
const qualifier
code cleanup		  
68 7000 d 1 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs		  
65 7000 d 2 h decky /SPARTAN/trunk/arch/ia32/ doxygen-style comments  
63 7000 d 4 h decky /SPARTAN/trunk/ const qualifier for print functions  
58 7002 d 20 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
57 7002 d 21 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
56 7002 d 22 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
52 7002 d 22 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().		  
51 7003 d 1 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.		  
50 7003 d 6 h jermar /SPARTAN/trunk/ Big indentation update.

Add Jakub Vana to AUTHORS.

Minor fixes.		  
49 7003 d 6 h vana /SPARTAN/trunk/arch/ia32/src/ Change indentation in context.s.  
48 7003 d 7 h vana /SPARTAN/trunk/arch/ia32/src/ Add missing function names.  
46 7003 d 7 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 7003 d 11 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 7005 d 8 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
38 7008 d 2 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
34 7011 d 4 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 7011 d 20 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.		  
32 7014 d 0 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
31 7015 d 5 h jermar /SPARTAN/trunk/ Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.		  
30 7015 d 11 h jermar /SPARTAN/trunk/arch/ia32/ Separate EBDA detection from MP Specification code. EBDA address will be needed during ACPI initialization.  
29 7016 d 4 h jermar /SPARTAN/trunk/arch/ia32/ Begin ACPI support.
ACPI support will be necessary for initialization of SMP systems with SMT (HyperThreading).		  
28 7016 d 8 h jermar /SPARTAN/trunk/ Small improvements.  
27 7016 d 23 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.		  
26 7019 d 7 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
24 7022 d 1 h jermar /SPARTAN/trunk/ Small fixes.  
23 7022 d 5 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.

21 7025 d 4 h jermar /SPARTAN/trunk/arch/ia32/ Minor changes and cleanups of recent modifications.  
18 7031 d 1 h jermar /SPARTAN/trunk/arch/ia32/ Cleanup floppy boot loader code and add missing stack initialization.  
17 7031 d 4 h jermar /SPARTAN/trunk/arch/ia32/boot/ Remove bogus line.
