368 6839 d 22 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
347 6847 d 15 h jermar /SPARTAN/trunk/ Documentation updates for amd64, mips32 and ia32.

Replace %L with %P printf() formatter in MPS and ACPI detection functions to print addresses in maximal width.

Tweak memmap.S and IA-32 and AMd64 boot.S.
Cancel unneeded instructions.
Replace cmpl $0, %ebx with testl %ebx, %ebx.
Move memmap.S data to K_DATA_START section.		  
300 6855 d 22 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6855 d 23 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
294 6856 d 2 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 6856 d 15 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.  
279 6857 d 13 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
277 6857 d 14 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!		  
273 6857 d 17 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.		  
269 6857 d 18 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
268 6857 d 18 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
267 6857 d 19 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		  
232 6859 d 19 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
205 6861 d 1 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
198 6861 d 14 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
195 6861 d 15 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option		  
177 6862 d 23 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.		  
170 6870 d 12 h jermar /SPARTAN/trunk/ Add comment to scheduler.c explaining the reason behind saving CPU priority of preempted thread.

Remove two unnecessary cpu_priority_high() calls.		  
131 6903 d 0 h jermar /SPARTAN/trunk/arch/ia32/src/ Initialize kmp_completion_wq during configuration via ACPI MADT.
Move some generic SMP configuration code from mps.c to smp.c.		  
129 6903 d 20 h jermar /SPARTAN/trunk/arch/ia32/ Implement ACPI MADT operations for interface used by kmp.
