341 6834 d 5 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
329 6836 d 1 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
319 6839 d 9 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
317 6839 d 9 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
313 6839 d 20 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.		  
306 6840 d 10 h palkovsky /SPARTAN/trunk/ Fixed mips boot process.
On interrupt saving registers, save $lo, $hi.
Add interrupt naming to asm files (mips).
Save only necessary registers on context switch (see mips ABI).
Fixed copyright info.		  
177 6848 d 7 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.		  
169 6856 d 21 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
147 6887 d 4 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.		  
135 6888 d 5 h jermar /SPARTAN/trunk/ Fix setters of page table attributes for both IA-32 and MIPS.  
134 6888 d 5 h decky /SPARTAN/trunk/arch/mips/include/mm/ Add missing asid.h  
125 6892 d 21 h jermar /SPARTAN/trunk/ Huge indentation fix.  
121 6893 d 21 h jermar /SPARTAN/trunk/ Begin MIPS implementation of 4-level page table interface.

Add email address to each item in doc/AUTHORS.

Correct type names in comments in mm/vm.c.
Introduce ptl0 pointer in vm_t.		  
120 6907 d 19 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.		  
105 6935 d 19 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.
