326 6836 d 20 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 6837 d 9 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 6839 d 11 h jermar /SPARTAN/trunk/ Make AMD64 gencontext.c consistent with MIPS gencontext.c  
317 6839 d 11 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
314 6839 d 22 h palkovsky /SPARTAN/trunk/ Small cleanups  
309 6840 d 11 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
307 6840 d 12 h palkovsky /SPARTAN/trunk/ Fixed things broken by last commit.  
306 6840 d 12 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.		  
303 6841 d 5 h palkovsky /SPARTAN/trunk/  
298 6841 d 9 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
295 6841 d 10 h palkovsky /SPARTAN/trunk/ Test that really tests SSE context switching.  
293 6841 d 22 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 6841 d 22 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().		  
289 6842 d 2 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.		  
288 6842 d 3 h jermar /SPARTAN/trunk/ Create tools/ directory.
Move helper scripts and tools out of src/ and arch/.		  
284 6842 d 12 h palkovsky /SPARTAN/trunk/src/  
283 6842 d 12 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
282 6842 d 13 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.		  
276 6843 d 0 h cejka /SPARTAN/trunk/src/debug/ Printf "E" and "F" format fixed.  
274 6843 d 2 h palkovsky /SPARTAN/trunk/src/
