418 6787 d 7 h jermar /SPARTAN/trunk/ sparc64 infrastructure.  
414 6791 d 18 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
413 6792 d 4 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.		  
391 6805 d 5 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.		  
389 6805 d 16 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().		  
376 6814 d 11 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!		  
368 6818 d 14 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
363 6820 d 6 h jermar /SPARTAN/trunk/arch/ Fix copyright notices.  
361 6820 d 7 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
343 6827 d 14 h jermar /SPARTAN/trunk/ Finish renaming of mips and ppc ports.  
342 6827 d 14 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
338 6828 d 12 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.		  
332 6828 d 15 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.		  
326 6830 d 3 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.		  
309 6833 d 18 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
294 6834 d 18 h jermar /SPARTAN/trunk/arch/ Add timeout to kmp() so that we don't deadlock while waiting for AP's to come up.

Improve comment in byteorder.h.		  
293 6835 d 4 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.		  
292 6835 d 4 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().		  
289 6835 d 8 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.		  
287 6835 d 12 h jermar /SPARTAN/trunk/arch/ppc/ Symtab support for PPC.
