314 6884 d 4 h palkovsky /SPARTAN/trunk/ Small cleanups  
312 6884 d 5 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 6884 d 6 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Minor after fixes to madt parsing  
310 6884 d 6 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 6884 d 18 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
305 6885 d 6 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 6885 d 12 h palkovsky /SPARTAN/trunk/  
302 6885 d 12 h palkovsky /SPARTAN/trunk/arch/ia32/src/drivers/ Fixed bad slave i8259 initialization.  
301 6885 d 15 h palkovsky /SPARTAN/trunk/arch/ Backported amd64 build process back to ia32.  
300 6885 d 15 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6885 d 15 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
294 6885 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 6886 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 6886 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().		  
291 6886 d 8 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 6886 d 8 h palkovsky /SPARTAN/trunk/arch/ia32/  
289 6886 d 8 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.		  
285 6886 d 17 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
282 6886 d 19 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.		  
281 6887 d 3 h palkovsky /SPARTAN/trunk/arch/ia32/src/ Fixed some stupid typos.  
280 6887 d 3 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6887 d 5 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
278 6887 d 6 h palkovsky /SPARTAN/trunk/arch/ia32/src/acpi/ Fixed ACPI to work correctly even in bochs.  
277 6887 d 6 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!		  
275 6887 d 8 h palkovsky /SPARTAN/trunk/arch/ Moved AMD64 kernel above 1MB.  
273 6887 d 9 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.		  
271 6887 d 10 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
269 6887 d 11 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
268 6887 d 11 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
267 6887 d 12 h decky /SPARTAN/trunk/arch/ia32/ proper way of initializing GDT during boot on IA-32, fixes the nasty hack
SMP might be still broken		  
266 6887 d 13 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
264 6887 d 15 h cejka /SPARTAN/trunk/ E option in printf added.  
262 6887 d 15 h decky /SPARTAN/trunk/arch/ia32/ alternative makefile for building with IA-32 cross-compiler  
259 6887 d 16 h palkovsky /SPARTAN/trunk/ Fixed asm problems in asm in atomic instructions.  
257 6887 d 18 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).

248 6888 d 9 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
247 6888 d 10 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Fix nasty bug in arch/mm/frame.c.
frame_region_not_free() takes address as its second argument, not size.		  
246 6888 d 10 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)

243 6888 d 12 h palkovsky /SPARTAN/trunk/ Resolved mapping of e820 boot area, so that it can be accessed as
e820table from 32-bit mode and e820table_boot from real mode.
