45 6966 d 18 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 6968 d 15 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
38 6971 d 9 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
34 6974 d 11 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 6975 d 3 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.		  
32 6977 d 6 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
31 6978 d 11 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 6978 d 18 h jermar /SPARTAN/trunk/arch/ia32/ Separate EBDA detection from MP Specification code. EBDA address will be needed during ACPI initialization.  
29 6979 d 10 h jermar /SPARTAN/trunk/arch/ia32/ Begin ACPI support.
ACPI support will be necessary for initialization of SMP systems with SMT (HyperThreading).		  
28 6979 d 15 h jermar /SPARTAN/trunk/ Small improvements.  
27 6980 d 6 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 6982 d 13 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
24 6985 d 8 h jermar /SPARTAN/trunk/ Small fixes.  
23 6985 d 11 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.  
22 6987 d 10 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
21 6988 d 11 h jermar /SPARTAN/trunk/arch/ia32/ Minor changes and cleanups of recent modifications.  
18 6994 d 8 h jermar /SPARTAN/trunk/arch/ia32/ Cleanup floppy boot loader code and add missing stack initialization.  
17 6994 d 11 h jermar /SPARTAN/trunk/arch/ia32/boot/ Remove bogus line.  
16 6994 d 11 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 6995 d 9 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.
