lapic3 branch rebased

lapic3 branch rebased

[Avi Kivity]

lapic3 has been rebased, compile tested, and pushed.  note that this 
does not include the patch-folding work I'd like to do before merging 
into master.

Thanks and verified it is fine for RHEL5U, XPSP2, FC5, Win2003. So feel
free to 
fold the patches and wanna to see merging soon :-)

FC6 SMP boots with one cpu only.  With -no-kvm-irqchip it boots fine.

Are you using the bios provided by kvm or the hacked one?  That may be 
the problem.

(I'm proceeding with the folding anyway)

Some progress -- I rebased lapic3 and folded some patches; new branch 
called lapic4, 100% equivalent to lapic3 in final result.

Patches folded:

 KVM: cleanups on user/kernel irqchip checking
 KVM: Fix state save bug
 KVM: remove status in kvm_lapic structure
 KVM: Restore apic_base to struct kvm_vcpu
 KVM: Fix crash due to apic being accessed beore initialization
 KVM: Add missing #include
 KVM: IOAPIC: Temporarily avoid reissuing irq on EOI
 KVM: IOAPIC: Avoid delivering apic messages to non-existent vcpus
 KVM: Rename KVM_CAP_PIC to KVM_CAP_IRQCHIP
 KVM: Fix minor warnings in lapic patch
 KVM: Fix oops destroying VM with virtual PIC

Patches kept:

 KVM: pending irq save/restore
 KVM: in-kernel LAPIC save and restore support
 KVM: in-kernel IOAPIC save and restore support
 KVM: Bypass irq_pending get/set when using in kernel irqchip
 KVM: Add get/set irqchip ioctls for in-kernel PIC live migration support
 KVM: Protect in-kernel pio using kvm->lock
 KVM: Emulate hlt in the kernel
 KVM: In-kernel I/O APIC model
 KVM: Emulate local APIC in kernel
 KVM: Define and use cr8 access functions
 KVM: Add support for in-kernel PIC emulation

I plan to do some minor renaming and code movement (to remove artifacts 
like a line being moved by a patch for no reason).  Will be in a new 
branch lapic5.

This is now done, containing the following changes:

- rename 'struct kvm_ioctl_pic' to 'struct kvm_pic_state'
- rename 'struct kvm_ioctl_ioapic' to 'struct kvm_ioapic_state'
- rearranged struct kvm_vcpu to reduce changes relative ro master

However, neither lapic4 nor lapic5 will boot Windows XP SP2 (ACPI HAL).  
I'll debug the Linux problem first.

Re: lapic3 branch rebased

Hi, Avi
In my testing for lapic5, I can boot Windows guest with UP ACPI HAL. 
And I cannot boot Windows Guest with SMP ACPI HAL even with enabling
smp=1

Thanks
Yunfeng

Hi,Avi
Do you see any timer issue on Lapic5?
On lapic5 I found that linux guest has a big time lag while running kernel build.
With network time the time cost is about 450s, but guest timer reports 899s.

I didn't meet the issue on lapic3.

Thanks
Yunfeng

Avi:
	I am just back from a travel and want to know what is next in
your plan.
	From the mailing list the XP ACPI HAL issue is fixed by Qing,
isn't it?

I assume it is (haven't checked myself).  But of course we need to get 
guest smp working.

I made some progress but it isn't working yet.  If you have something, 
please post it.

No, I didn't. lapic3 and lapic5 shouldn't be that different...
