153 6886 d 16 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 6904 d 1 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 6904 d 1 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
139 6904 d 23 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
135 6905 d 2 h jermar /SPARTAN/trunk/ Fix setters of page table attributes for both IA-32 and MIPS.  
129 6906 d 0 h jermar /SPARTAN/trunk/arch/ia32/ Implement ACPI MADT operations for interface used by kmp.  
128 6907 d 3 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 6909 d 18 h jermar /SPARTAN/trunk/ Huge indentation fix.  
120 6924 d 16 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 6925 d 19 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.		  
116 6944 d 23 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 6945 d 16 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 6948 d 19 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 6952 d 2 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 6952 d 16 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.		  
99 6960 d 7 h jermar /SPARTAN/trunk/ Replace "THREAD->cpu" with "CPU" in scheduler().

Add trailing '\n' to memmap.h
Fix some translations.
Relpace one Czech sentence with its English translation.		  
98 6961 d 0 h cejka /SPARTAN/trunk/arch/ia32/ first version of e820 memmap  
95 6962 d 5 h cejka /SPARTAN/trunk/arch/ia32/ Started memory map support.  
92 6965 d 22 h jermar /SPARTAN/trunk/ FPU work.
FPU code cleanup, add/fix copyright notices where needed.
Fix PI calculation to use double n instead of int n.
Make FPU test #1 even more stressing.

Re-enable O3 again.
Revert Makefile.config not to compile in any tests.		  
84 6967 d 4 h vana /SPARTAN/trunk/ IA-32 FPU lazy context switching.
Doesn't work on Bochs and sometimes produces wrong results on P4.
Seems to work on VMware and PII.

Build script for IA-32 changed to build floppy images (image.bin) 1440K long.
