Hi All,
The previous thread has gotten rather convoluted, so I'm going to have a go at extracting a brief summary of topics and suggesting some straw man timings. These are all discussion topics, so name just indicates who I think will do the intro. Note I'd suggest we keep fairly tightly to timings and if it looks like a particular conversation is going long, we schedule a follow up.
VLPI Migration support on Gic V4.1: lushenming (Huawei) - 15 mins Topic requested by Lorenzo Pieralisi (ARM) In GICv4.1, migration has been supported except for (directly-injected) VLPI. And GICv4.1 spec explicitly gives a way to get the VLPI's pending state (which was crucially missing in GICv4.0). So we make VLPI migration capable on GICv4.1 in this patch set. (5 min) Intro to the work, then questions (10 min).
vCPU HP: Salil Mehta (Huawei) 25 mins. Lorenzo has questions + it's an expansive topic. I would suggest interested people catch up with slides from KVM forum 2020 https://kvmforum2020.sched.com/event/eE4m/challenges-in-supporting-virtual-c... (video not public yet) (5 min) Open questions statement, then move to discussion.
RMR related topics - follow up on last call: Lorenzo Pieralisi (ARM) - 5 mins There were outstanding questions around whether PCIe reenumeration could cause problems here. (Lorenzo, Shameer, there were a few other open questions around this topic, do we have any other updates for Monday?)
I have an update on the specs which includes policy to prevent PCI reenumeration and the IOVA reuse Shameer mentioned.
I think this should wrap it up.
Generic Initiators: Jonathan Cameron (Huawei) - 5 mins Very brief intro to GIs + current status + opening for questions. More detail etc in this email. https://op-lists.linaro.org/pipermail/linaro-open-discussions/2020-November/...
Ideally slides should go to Mike in advance to upload to the collaborate page.
I will prepare one slide myself monday morning for my slot, I am off till then.
Anything I've missed?
Not really, thanks a lot for writing it up !!
Thanks, Lorenzo
