323 6865 d 3 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 6867 d 6 h jermar /SPARTAN/trunk/arch/ia32/src/ Optimize assembler code according to the knoweledge of IA-32 ABI.  
315 6867 d 7 h jermar /SPARTAN/trunk/arch/ia32/ Make IA-32 userspace stack be aligned on doubleword boundary.
In userspace(), mark "eax" as clobbered register.		  
314 6867 d 16 h palkovsky /SPARTAN/trunk/ Small cleanups  
312 6867 d 17 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 6867 d 17 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Minor after fixes to madt parsing  
310 6867 d 18 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 6868 d 5 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
305 6868 d 17 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.		  
302 6869 d 0 h palkovsky /SPARTAN/trunk/arch/ia32/src/drivers/ Fixed bad slave i8259 initialization.  
300 6869 d 2 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6869 d 3 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
294 6869 d 5 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.		  
291 6869 d 19 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.  
285 6870 d 5 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
282 6870 d 7 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 6870 d 15 h palkovsky /SPARTAN/trunk/arch/ia32/src/ Fixed some stupid typos.  
280 6870 d 15 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6870 d 17 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
278 6870 d 18 h palkovsky /SPARTAN/trunk/arch/ia32/src/acpi/ Fixed ACPI to work correctly even in bochs.  
277 6870 d 18 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!		  
273 6870 d 21 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.		  
271 6870 d 22 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
269 6870 d 22 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
268 6870 d 22 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
267 6870 d 23 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 6871 d 1 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
264 6871 d 2 h cejka /SPARTAN/trunk/ E option in printf added.  
257 6871 d 5 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.		  
247 6871 d 22 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.

243 6872 d 0 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.		  
235 6872 d 22 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
233 6872 d 23 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Do not use the unmapped addresses of e820 kernel structures.
Use PA2KA() to access the e820 counter and memtable.		  
232 6872 d 23 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
230 6873 d 0 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
224 6873 d 5 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.
