Here are serval fixup & optmizitions for hgatp detect according to the RISC-V Privileged Architecture Spec.
---
Changes in v4:
- Involve ("RISC-V: KVM: Prevent HGATP_MODE_BARE passed"), which
explain why gstage_mode_detect needs reset HGATP to zero.
Changes in v3:
- Add "Fixes" tag.
- Involve("RISC-V: KVM: Remove unnecessary HGATP csr_read"), which
depends on patch 1.
Changes in v2:
- Fixed build error since kvm_riscv_gstage_mode() has been modified.
