326 6856 d 6 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 6856 d 19 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.		  
316 6858 d 23 h jermar /SPARTAN/trunk/arch/ia32/src/ Optimize assembler code according to the knoweledge of IA-32 ABI.  
315 6859 d 0 h jermar /SPARTAN/trunk/arch/ia32/ Make IA-32 userspace stack be aligned on doubleword boundary.
In userspace(), mark "eax" as clobbered register.		  
314 6859 d 8 h palkovsky /SPARTAN/trunk/ Small cleanups  
312 6859 d 9 h jermar /SPARTAN/trunk/arch/ia32/ According to IA-32 ABI, %edx and %ecx don't have to be saved accross function calls.
Remove these registers from context_t and adjust context_save() and context_restore() to make use of this fact.		  
311 6859 d 10 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Minor after fixes to madt parsing  
310 6859 d 10 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Fixed possible non-consequentive local apic madt entries
Request for peer review - was not possible to test.		  
309 6859 d 21 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
305 6860 d 9 h jermar /SPARTAN/trunk/ Change processor type in simics.conf to x86-hammer.
This way it supports both IA-32 and AMD64.

Fix comment in i8259.c.		  
303 6860 d 15 h palkovsky /SPARTAN/trunk/  
302 6860 d 16 h palkovsky /SPARTAN/trunk/arch/ia32/src/drivers/ Fixed bad slave i8259 initialization.  
301 6860 d 18 h palkovsky /SPARTAN/trunk/arch/ Backported amd64 build process back to ia32.  
300 6860 d 19 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6860 d 19 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
294 6860 d 22 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 6861 d 8 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 6861 d 8 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().		  
291 6861 d 11 h jermar /SPARTAN/trunk/arch/ia32/src/smp/ AP cpus are not supposed to touch A20 for this bit is enabled by the BSP cpu.  
290 6861 d 11 h palkovsky /SPARTAN/trunk/arch/ia32/
