149 6904 d 4 h jermar /SPARTAN/trunk/ Fix IA-32's get_memory_size() to return size of memory in bytes instead of in kilobytes.
Some cosmetics in memory map detection.
The IA-32 kernel is functional again.		  
146 6909 d 10 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
144 6909 d 10 h vana /SPARTAN/trunk/ Coding style fix  
143 6909 d 11 h vana /SPARTAN/trunk/ Disable alignment check  
142 6909 d 11 h vana /SPARTAN/trunk/arch/ia32/src/ Typing error fixed  
141 6909 d 11 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
139 6910 d 8 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
137 6910 d 9 h vana /SPARTAN/trunk/arch/ia32/src/ Comments  
136 6910 d 10 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.  
132 6910 d 13 h vana /SPARTAN/trunk/arch/ia32/ Added support for error-word generating exceptions in return routine.  
131 6910 d 13 h jermar /SPARTAN/trunk/arch/ia32/src/ Initialize kmp_completion_wq during configuration via ACPI MADT.
Move some generic SMP configuration code from mps.c to smp.c.		  
129 6911 d 9 h jermar /SPARTAN/trunk/arch/ia32/ Implement ACPI MADT operations for interface used by kmp.  
128 6912 d 12 h jermar /SPARTAN/trunk/arch/ia32/ Create IA-32 interface for bringing SMP up.
This interface hides differences between ACPI MADT and MPS configuration tables.
Provide MPS implementation thereof.		  
127 6912 d 13 h jermar /SPARTAN/trunk/arch/ Copyright owner of arch/mips/src/mm/asid.c is Martin Decky.

ACPI code now understands L_APIC and IO_APIC entries in MADT.		  
125 6915 d 2 h jermar /SPARTAN/trunk/ Huge indentation fix.  
120 6930 d 1 h jermar /SPARTAN/trunk/ Generic 4-level page tables interface & implementation (review & test).
Implement more architecture dependant macros on IA-32.
Provide fake implementation on IA-64 and MIPS.
Convert map_page_to_frame() to use the new interface.
Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.		  
117 6946 d 8 h jermar /SPARTAN/trunk/ Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.

Tiny changes here and there.		  
116 6950 d 8 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.		  
115 6951 d 1 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.		  
113 6954 d 0 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.
