267 6852 d 6 h decky /SPARTAN/trunk/arch/ia32/ proper way of initializing GDT during boot on IA-32, fixes the nasty hack
SMP might be still broken		  
247 6853 d 4 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Fix nasty bug in arch/mm/frame.c.
frame_region_not_free() takes address as its second argument, not size.		  
246 6853 d 5 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)  
243 6853 d 7 h palkovsky /SPARTAN/trunk/ Resolved mapping of e820 boot area, so that it can be accessed as
e820table from 32-bit mode and e820table_boot from real mode.		  
235 6854 d 5 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
233 6854 d 5 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Do not use the unmapped addresses of e820 kernel structures.
Use PA2KA() to access the e820 counter and memtable.		  
205 6855 d 12 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
195 6856 d 2 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option		  
187 6856 d 8 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.		  
182 6856 d 12 h cejka /SPARTAN/trunk/ Test for printf added.  
177 6857 d 10 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.		  
167 6867 d 8 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.		  
149 6891 d 2 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 6896 d 7 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
139 6897 d 5 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 6902 d 0 h jermar /SPARTAN/trunk/ Huge indentation fix.  
120 6916 d 22 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.		  
116 6937 d 5 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 6937 d 22 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 6940 d 21 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.
