[v3,0/3] target/riscv: Apply KVM policy to ISA extensions

Message

Mayuresh Chitale Dec. 8, 2022, 2:54 p.m. UTC

Currently the single and multi letter ISA extensions exposed to the
guest vcpu don't confirm to the KVM policies. This patchset updates the kvm headers
and applies policies set in KVM to the extensions exposed to the guest.

These patches can also be found on riscv_kvm_ext_v3 branch at:
https://github.com/mdchitale/qemu.git

Changes in v3:
- Address comments from Bin Meng

Changes in v2:
- Rebase to latest riscv-to-apply.next
- Update linux headers to version 6.1-rc8
- Add reviewed by tags

Mayuresh Chitale (3):
  update-linux-headers: Version 6.1-rc8
  target/riscv: Extend isa_ext_data for single letter extensions
  target/riscv: kvm: Support selecting VCPU extensions
