With https://github.com/OP-TEE/build/pull/663 I'm trying to upstream the Hafnium setup. Once that's merged please create a pull request against https://github.com/OP-TEE/build and we can continue reviewing this patch there.
Sure.
Thanks, Shiju
Thanks, Jens

Probably not one for this month, but if James is willing I'd like to have a discussion around what everyone think the additional interfaces to resctrl needed to support the 'rest' of MPAM would look like. Might save some time on coding up things that look radically different from what might eventually go upstream (with inevitable problems maintaining yet another version of MPAM for the distros we care about)
Perhaps September sometime? I want plenty of time to think about it before a discussion!

Probably not one for this month, but if James is willing I'd like to have a discussion around what everyone think the additional interfaces to resctrl needed to support the 'rest' of MPAM would look like. Might save some time on coding up things that look radically different from what might eventually go upstream (with inevitable problems maintaining yet another version of MPAM for the distros we care about)
Perhaps September sometime? I want plenty of time to think about it before a discussion!
It is important that we have one for the vCPU Hotplug sync-up.
Ah. I wasn't clear on this, but absolutely agree on vCPU HP sync shortly as you requested.
Just wanted to put this additional topic on the table for a future meeting.
Jonathan

Hi Jonathan,
Interesting timing, there are a number of these squeezing out of the woodwork! There has been a suggestion to discuss this, maybe at plumbers as Intel have their own new-stuff. I'll try and make sure you see anything that happens in that area.
I think as long as any new interface refers to something else in sysfs, like the L3 schema refers to cache_id, then it should be portable between platforms. I'd love to decouple to format of the control from the thing it controls ... we'll see what Intel need/want in this area.
I can pick these things up into my tree so we're all testing the same thing - but anyone user-space ABI that isn't accepted upstream is pretty risky. Ultimately I don't think we can guess what it will look like eventually.
Thanks,
James

Perhaps September sometime? I want plenty of time to think about it before a discussion!

Yeah - I came across the Marvell stuff later in the day and interesting Intel also have new stuff to add.
Plumbers sessions sounds like a good idea. BoF maybe if it doesn't fit anywhere else? (I've not really thought about if it could be squeezed into a uconf)
Obviously I'd love to see this move before November, but realistically it probably won't even if discussions get started.
I think as long as any new interface refers to something else in sysfs, like the L3 schema refers to cache_id, then it should be portable between platforms. I'd love to decouple to format of the control from the thing it controls ... we'll see what Intel need/want in this area.

Understood. I need to do a trawl through what we have in OpenEuler as well as that is still receiving fixes and features that aren't going to you currently.

I could not really follow the question related to SBSA/QEmu compliance, if you could summarize it and post it on this mailing list that would be great.
My understanding was that Salil wanted to know if any of the work that is being done for vCPU hot plug/unplug would be incompatible with SBSA and, because of that, would not work with current QEMU SBSA platform implementation.

My understanding was that Salil wanted to know if any of the work that is being done for vCPU hot plug/unplug would be incompatible with SBSA and, because of that, would not work with current QEMU SBSA platform implementation.
Not exactly (by my understanding, Salil may well give more details later). This is all about internal QEMU implementation details unrelated to the SBSA specifications.
If the code were to be made flexible enough to support vCPU hotplug on SBSA QEMU when it is being used with KVM as a virtual machine (or potentially TCG) would anyone actually find it useful?
It's a question of whether it is worth bothering to make the code generic enough and indeed carry out the testing necessary to support what to me is a feature that no one will use. + the testing burden alone makes it seem like a bad idea. Arguably the code could be designed with use under both SBSA QEMU and virt in mind (+ other machines) but without actually going the last step to be able to test that flexibility on a couple of machines the design wouldn't be verified except for virt.
Mind you I also argued it was pointless on TCG and yet people seem to want that for 'completeness' even though I've not seen anyone state a use case and it at least doubles the number of tests.
Jonathan

Leo

I could not really follow the question related to SBSA/QEmu compliance, if you could summarize it and post it on this mailing list that would be great.
Yes, sure. We have made certain workarounds within the Qemu to get over the limitations posed by the Arm architecture. These are primarily related to the VGIC initialization like redistributors, GIC CPU Interfaces and creation of the vcpus itself.
Qemu has to create and initialize all of these within KVM for all of the 'possible vcpus' during initialization. This can only be done only once. Hence, we create all the KVM VCPUs, KVM VGIC redistributors etc. once during initialization. Qemu has got representation of these in its model/QOM as well.
Once we bring the concept of hot-unplugging of vCPUs, we should *ideally* destroy all the related objects in the model/QOM. Architecture wise, of course this is not allowed.
we only destroy the vcpu objects in the QOM but their related GIC components like redistributors, GIC CPU interfaces are always kept initialized. These GIC CPU Interface or GICV3CPUState objects kind of remain in disconnected state with their absent vcpu objects in the QOM. When these absent vcpus get hotplugged later and their vcpu objects get created (and initialized at the KVM) again in the QOM then they are connected back to the GIC CPU Interface i.e. GICV3CPUState objects. Similarly, for a vcpu hot-unplug a reverse action takes place. This workaround is not very clean design wise but works.
As per the architecture GIC CPU Interfaces and the CPUs are physically tied up together and as I understand, there is no way to power down either of these components. Above discussed model behavior as not what architecture would expect.
Hence, I thought to raise the point about this to check if this in any way will affect qemu-sbsa.

I could not really follow the question related to SBSA/QEmu compliance, if you could summarize it and post it on this mailing list that would be great.
Yes, sure. We have made certain workarounds within the Qemu to get over the limitations posed by the Arm architecture. These are primarily related to the VGIC initialization like redistributors, GIC CPU Interfaces and creation of the vcpus itself.
Qemu has to create and initialize all of these within KVM for all of the 'possible vcpus' during initialization. This can only be done only once. Hence, we create all the KVM VCPUs, KVM VGIC redistributors etc. once during initialization. Qemu has got representation of these in its model/QOM as well.
Once we bring the concept of hot-unplugging of vCPUs, we should *ideally* destroy all the related objects in the model/QOM. Architecture wise, of course this is not allowed.
we only destroy the vcpu objects in the QOM but their related GIC components like redistributors, GIC CPU interfaces are always kept initialized. These GIC CPU Interface or GICV3CPUState objects kind of remain in disconnected state with their absent vcpu objects in the QOM. When these absent vcpus get hotplugged later and their vcpu objects get created (and initialized at the KVM) again in the QOM then they are connected back to the GIC CPU Interface i.e. GICV3CPUState objects. Similarly, for a vcpu hot-unplug a reverse action takes place. This workaround is not very clean design wise but works.
As per the architecture GIC CPU Interfaces and the CPUs are physically tied up together and as I understand, there is no way to power down either of these components. Above discussed model behavior as not what architecture would expect.
Hence, I thought to raise the point about this to check if this in any way will affect qemu-sbsa.
Thanks Salil.

Add changes to run a secondary OP-TEE at S-EL1 for SPMC_AT_EL=2, where Hafnium is loaded at S-EL2.
Signed-off-by: Shiju Jose shiju.jose@huawei.com
With https://github.com/OP-TEE/build/pull/663 I'm trying to upstream the Hafnium setup. Once that's merged please create a pull request against https://github.com/OP-TEE/build and we can continue reviewing this patch there.
Sure.
Thanks, Shiju
Thanks, Jens
