187 6840 d 22 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.
 
180 6841 d 15 h jermar /SPARTAN/trunk/ Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'.

Fix heap initialization to take 'heap_delta' into account.

Implement IA-64 get_stack_base().

Adjust SP_DELTA's to consider one extra word on stack.
(So that the stack pointer is within appropriate limits even on IA-64).

More #include cleanup.
 
177 6842 d 0 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.
 
173 6845 d 15 h jermar /SPARTAN/trunk/ Preparations for weaker preemption model.
Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy.
 
169 6850 d 13 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
153 6863 d 12 h jermar /SPARTAN/trunk/ Add memory barriers into spinlock_*().
Implement CS_{ENTER|LEAVE}_BARRIER() for IA-32 (no-op).
Provide incomplete CS_{ENTER|LEAVE}_BARRIER() macros for IA-64 and MIPS as well.

Small changes here and there.
 
147 6880 d 21 h jermar /SPARTAN/trunk/arch/ Add missing memory_init.h files for IA-64 and MIPS architectures.
Fix typo in IA-32's memory_init.h.
 
146 6880 d 21 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
139 6881 d 19 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
135 6881 d 22 h jermar /SPARTAN/trunk/ Fix setters of page table attributes for both IA-32 and MIPS.  
129 6882 d 21 h jermar /SPARTAN/trunk/arch/ia32/ Implement ACPI MADT operations for interface used by kmp.  
128 6883 d 23 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.
 
125 6886 d 14 h jermar /SPARTAN/trunk/ Huge indentation fix.  
120 6901 d 12 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.
 
119 6902 d 15 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.
 
116 6921 d 19 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 6922 d 12 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.
 
111 6925 d 16 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.
 
106 6928 d 22 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 6929 d 12 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.
