332 6853 d 16 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 6855 d 4 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.
 
323 6855 d 17 h jermar /SPARTAN/trunk/ Add comments for new floating point modifiers to print.c.
Remove left-over comments from AMD64 and IA-32 page.c.
Coding style clean up.
 
318 6857 d 19 h jermar /SPARTAN/trunk/ Make AMD64 gencontext.c consistent with MIPS gencontext.c  
313 6858 d 6 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.
 
309 6858 d 19 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
299 6859 d 17 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Better stack recognition in stack content dump.  
297 6859 d 17 h palkovsky /SPARTAN/trunk/ Symtab now contains variables  
296 6859 d 18 h palkovsky /SPARTAN/trunk/ More logical fpu_context_engaged setting.
The sse1 test now correctly tests for thread migration settings.
 
293 6860 d 5 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.
 
288 6860 d 11 h jermar /SPARTAN/trunk/ Create tools/ directory.
Move helper scripts and tools out of src/ and arch/.
 
286 6860 d 19 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Codingstyle changes  
283 6860 d 20 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
282 6860 d 21 h palkovsky /SPARTAN/trunk/ Fixed gdtr naming issues after ia32 changes.
Fixed stack alignment on new thread to by multiple of 16,
we are now ABI-correct and we do not #GP on va_arg to boot.
Fixed bad exception register names reporting.
Fixed bad _hardcoded_load_addr, which caused allocation of kernel text
frames.
 
277 6861 d 8 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!
 
275 6861 d 10 h palkovsky /SPARTAN/trunk/arch/ Moved AMD64 kernel above 1MB.  
273 6861 d 11 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.
 
268 6861 d 12 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
266 6861 d 15 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
265 6861 d 16 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
 
257 6861 d 19 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.
 
252 6861 d 22 h palkovsky /SPARTAN/trunk/arch/amd64/ Added volatile to inb/outb, so that it does not optimeze
lot of things out anymore.
Working delay loop.
 
251 6862 d 5 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.
 
242 6862 d 15 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
