Talks
MAD24-411 Gunyah Accelerator for Qemu
Session
- Friday, 17 May 11:30 - 11:55
- Room: Keynote | Zaragoza III+IV
Gunyah is a high performance and scalable Type-1 hypervisor built for demanding battery-powered, real-time, safety critical systems and currently supports ARM64 architecture. A Linux driver for it is being developed taking active inputs from kernel maintainers and community. It will allow applications such as Qemu to interact with the hypervisor for VM management. The Linux driver is expected to be merged upstream very soon this year. Support for gunyah hypervisor in Qemu is also being developed concurrently with couple of versions already published. In this session, we intend to briefly cover Gunyah hypervisor overview, proposed features of its Linux driver and finally the proposed changes to Qemu for supporting Gunyah. We discuss the proposed changes to manage both confidential guests and non-confidential (aka unprotected) guests.
