[QEMU-traditional] ACPI AML code races with QEMU updating the vCPU count when hotplugging more than ~14 VCPUs.

This is a race so the amount varies but on a 4PCPU box
I seem to get only ~14 out of 16 vCPUs I want to online.

The issue at hand is that QEMU xenstore.c hotplug code
does to the command: xl vcpu-set latest 16
(guest config has vcpus=1, maxvcpus=32) this:


QEMU:						Guest OS:
-xenstore_process_vcpu_set_event
 -> Gets an XenBus notification for CPU1
 -> Updates the gpe_state.cpus_state bitfield.       
	-> Pulses the ACPI SCI 
						- ACPI SCI kicks in

 -> Gets an XenBus notification for CPU2
 -> Updates the gpe_state.cpus_state bitfield.
	-> Pulses the ACPI SCI 

 -> Gets an XenBus notification for CPU3
 -> Updates the gpe_state.cpus_state bitfield.
	-> Pulses the ACPI SCI 
   ...
						 - Method(PRST) invoked
							  
 -> Gets an XenBus notification for CPU12
 -> Updates the gpe_state.cpus_state bitfield.
	-> Pulses the ACPI SCI 
						  - reads AF00 for CPU state
						    [gets 0xff]
						  - reads AF02 [gets 0x7f]

							
 -> Gets an XenBus notification for CPU13
 -> Updates the gpe_state.cpus_state bitfield.
	-> Pulses the ACPI SCI 

	.. until VCPU 16
						 - Method PRST updates
						   PR01 through 13 FLG
						   entry.
						 - PR01->PR13 _MAD
						   invoked.

						 - Brings up 13 CPUs.

While QEMU updates the rest of the cpus_state bitfields the ACPI AML
only does the CPU hotplug on those it had read. For reference
please see the debug patch and also the QEMU log. Look for
'gpe_cpus_readb'.

My thinking of how to fix this is just to add in
xenstore_process_vcpu_set_event
 - a scan for all of the other availability/cpu states.
 - for each of the cpu availability states query the
   gpe_state.cpus_state and if different modify them (and set
   a bool that one of them was modified).
 - When done scanning and if the bool was set, then kick of the
   qemu_irq_pulse.

Then if the other events are triggered we can just check the
gpe_state.cpus_state against what XenBus thinks and if they
are the same just return without doing the qemu_irq_pulse.

Thoughts?

Could you check if switching from level to edge handling in AML helps?

upstream QEMU and cpu hotplug Was: [QEMU-traditional] ACPI AML code races with QEMU updating the vCPU count when hotplugging more than ~14 VCPUs.

[Stefano Stabellini]

This reminded me to look for cpu hotplug in upstream QEMU and it looks
like we don't support this feature at all there :-(

We don't even parse the cpu field on xenstore.

What are we going to do about this in 4.3?

Sadly did not help. I am thinking just to try out the outline of
the code I wrote and see how it works. 

BTW, this is with the traditional Xen QEMU. I couldn't get the SeaBIOS
QEMU to work with this and I think that is b/c the XenStore monitoring
of the CPUs availability is just not there.

Ah, it might be via the QMP layer thingy. I should look in that.

[Stefano Stabellini]

FYI the appended commits are missing in upstream QEMU.

Given the timeframe available I would be happy to carry a straight
port of these commits, as close as possible to the originals, in the
qemu-upstrem-4.3 tree.
We can revert them later (Xen 4.4) and implement the feature properly by
sending the patches to qemu-devel and following the development process
there. There is no time to do that in time for the 4.3 release.

    Fix vcpu hotplug bug: get correct vcpu_avail bitmap
    
    Currently qemu has a bug: When maxvcpus > 64, qemu will get wrong
    vcpu bitmap (s->cpus_sts[i]) since it only get bitmap from a long variable.
    
    This patch, cooperate with another xend python patch, is to fix this bug.
    This patch get hex string from xend, transfer it to correct vcpu_avail bitmap
    which saved at an uint32_t array.

    Implement 'xm vcpu-set' command for HVM guest
    
    Currently Xen has 'xm vcpu-set' command for PV domain, but not
    available for HVM domain.  This patch is use to enable 'xm vcpu-set'
    command for HVM domain. It setup vcpu watch at xenstore, and at qemu
    side, handle vcpu online/offline accordingly.  With this patch, 'xm
    vcpu-set' command works for both PV and HVM guest with same format.

    piix4acpi, xen: change in ACPI to match the change in the BIOS.
    
    Some change have been introduced in the Xen firmware to match QEMU's
    BIOS.  So this patch adds the new sleep state values and handle old
    and new ACPI IOPort mapping.
    
    QEMU-Xen uses new ioport by default, but if it's a saved state with old
    firmware, it unmaps the new ioport and maps the old one.
