Topics discussed:
- SBI spec version -- There is new version of PMU extension available. It's just a rebase on top of current master. -- Mark suggested that security working group should review the PMU extension before it is merged. -- v0.3 should include PMU extension. Should it be part of Level 0 platform ? -- Can we tag it as v1.0 if that's what going to be included in platform specification ? -- We should document the remaining TODO items for SBI specification.
- Platform specification -- We need to have a tentative timeline for different levels of platform specification -- Can we include AIA in level 0 spec ? -- Most of the members present today agreed that we can focus on what exists today (i.e. PLIC) for level 0. -- AIA can be targeted towards the next level. -- Paul suggested that the stake holders from distro(i.e. debian/fedora/ubuntu/OpenSuse) and hardware vendors (SiFive/Microchip/Alibaba) should be taken into confidence when we have the actual spec. This makes a lot of sense. Otherwise, we may end up in a situation where no hardware vendors is compliant with the spec. -- Few discussion about detailed definition of RVA19. Mark hinted that it should be available early 2021. It may be renamed to RVA20.
- Mark also declared that CTO office has a budget to buy few HiFive Unmatched boards. It will be distributed to anybody working on open source software development for RISC-V. The obvious ones are distro folks.
- Nothing related to hypervisor was discussed today.
