116 6903 d 11 h jermar /SPARTAN/trunk/ Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries.
Change ACPI map_sdt() to use map_structure().

Small changes in MPS code.
The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space.
Zero TSS descriptor in the newly prepared GDT.		  
113 6907 d 3 h jermar /SPARTAN/trunk/ SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.

Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.

Usual cosmetics.		  
110 6908 d 12 h jermar /SPARTAN/trunk/ SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.

MIPS.
Move msim dprinter device to 0xB0000000.
This address is from kseg1 (unmapped, uncached) segment.		  
72 6933 d 7 h decky /SPARTAN/trunk/ size_t usage
const qualifier
code cleanup		  
68 6933 d 8 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs		  
34 6944 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 6945 d 3 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.		  
32 6947 d 6 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
30 6948 d 17 h jermar /SPARTAN/trunk/arch/ia32/ Separate EBDA detection from MP Specification code. EBDA address will be needed during ACPI initialization.  
29 6949 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 6949 d 15 h jermar /SPARTAN/trunk/ Small improvements.  
27 6950 d 5 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.		  
13 7007 d 5 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 7008 d 3 h jermar /SPARTAN/trunk/arch/ia32/src/smp/ Fix the algorithm for counting MP Configuration Table checksums.  
11 7008 d 4 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
1 7015 d 10 h jermar /SPARTAN/ Initial import
