187 7006 d 8 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.		  
182 7006 d 12 h cejka /SPARTAN/trunk/ Test for printf added.  
177 7007 d 9 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 7017 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 7041 d 1 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 7046 d 6 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
139 7047 d 4 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 7051 d 23 h jermar /SPARTAN/trunk/ Huge indentation fix.  
120 7066 d 21 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 7087 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 7087 d 21 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 7090 d 20 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 7092 d 6 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.		  
109 7094 d 1 h jermar /SPARTAN/trunk/ Discard 'copy' parameter of map_page_to_frame().
Introduce 'root' parameter of map_page_to_frame().
If 'root' is zero, page directory address is read from CPU.
Otherwise 'root' is used as page directory address.

Add missing word to new doxygen-style comments in scheduler.c.		  
106 7094 d 8 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.		  
105 7094 d 21 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.		  
34 7128 d 4 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.		  
11 7191 d 21 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
7 7194 d 9 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
Added architecture-independent ipi_broadcast().		  
6 7195 d 12 h jermar /SPARTAN/trunk/ shootdown vs. shutdown
