2022-04-19 QEMU Meeting

On April 19th there was an HPP Arch monthly arch call. The meeting focused on QEMU and we broadened the focus beyond just HPP to include some topics that effect other edge and some server cases.

Open

@Bill Mills ' presentation on HPP plans and other ideas being floated.

Open

Edgar Iglesias' presentation about Xilinx QEMU status and plans.

In addition @Alex Bennée gave a verbal update on Linaro’s QEMU plans from a core group POV.

• The core Linaro team is 3 people, although engineers from other areas often contribute (e.g. sbsa-ref)

• The main focus this year will be to focus on A profile in order to enable emulation of a real armv8.4 CPU

  • QEMU-414: QEMU ARM Cortex-A76 vCPU for TCGClosed then QEMU-421: QEMU ARM Neoverse N1 vCPU for TCGClosed

  • These concrete vCPUs are useful for places where -cpu max is too volatile

• This will be good prep work for the following goal of getting to armv9.x w/ CCA

  • Remaining v8.x cards: QEMU-471: QEMU ARM v9.0 Baseline CPU for TCGClosed

• Also looking to enable SME: QEMU-442: ARMv9 Scalable Matrix ExtensionsClosed
