58 6989 d 16 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
57 6989 d 17 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
56 6989 d 18 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
52 6989 d 18 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 6989 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.		  
50 6990 d 2 h jermar /SPARTAN/trunk/ Big indentation update.

Add Jakub Vana to AUTHORS.

Minor fixes.		  
49 6990 d 2 h vana /SPARTAN/trunk/arch/ia32/src/ Change indentation in context.s.  
48 6990 d 3 h vana /SPARTAN/trunk/arch/ia32/src/ Add missing function names.  
46 6990 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 6990 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 6992 d 4 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
38 6994 d 22 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
34 6998 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 6998 d 16 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.		  
32 7000 d 20 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
31 7002 d 1 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 7002 d 7 h jermar /SPARTAN/trunk/arch/ia32/ Separate EBDA detection from MP Specification code. EBDA address will be needed during ACPI initialization.  
29 7003 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 7003 d 4 h jermar /SPARTAN/trunk/ Small improvements.  
27 7003 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.		  
26 7006 d 3 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
24 7008 d 21 h jermar /SPARTAN/trunk/ Small fixes.  
23 7009 d 1 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.  
22 7010 d 23 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
21 7012 d 0 h jermar /SPARTAN/trunk/arch/ia32/ Minor changes and cleanups of recent modifications.  
18 7017 d 21 h jermar /SPARTAN/trunk/arch/ia32/ Cleanup floppy boot loader code and add missing stack initialization.  
17 7018 d 0 h jermar /SPARTAN/trunk/arch/ia32/boot/ Remove bogus line.  
16 7018 d 0 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.		  
15 7018 d 23 h jermar /SPARTAN/trunk/ Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.		  
13 7060 d 18 h jermar /SPARTAN/trunk/arch/ia32/ MP Specification says that MP Configuration Table extended entries with unrecongised types should be skipped rather than paniced on.  
12 7061 d 17 h jermar /SPARTAN/trunk/arch/ia32/src/smp/ Fix the algorithm for counting MP Configuration Table checksums.  
11 7061 d 17 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
10 7062 d 5 h jermar /SPARTAN/trunk/ Be more careful when sending IPI on UP configured as SMP.  
7 7064 d 5 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
Added architecture-independent ipi_broadcast().		  
6 7065 d 8 h jermar /SPARTAN/trunk/ shootdown vs. shutdown  
5 7065 d 19 h jermar /SPARTAN/trunk/ TLB shootdown.  
1 7068 d 23 h jermar /SPARTAN/ Initial import
