Subject: [PATCH v3 00/13] RISC-V: Update the Hypervisor spec to v0.6.1
Date: Wed, 12 Aug 2020 12:13:14 -0700

This series updates the experimental QEMU RISC-V Hypervisor spec to the
v0.6.1 draft implementation.

THis includes support for the new 2-stage lookup instructions and the new

It also includes the new 0.6.1 support for the virtual instruction

This was tested by running 32-bit and 64-bit Xvisor on QEMU and starting
Linux guests.

 - Rebase on master
 - Update to v0.6.1

Alistair Francis (13):
  target/riscv: Allow setting a two-stage lookup in the virt status
  target/riscv: Allow generating hlv/hlvx/hsv instructions
  target/riscv: Do two-stage lookups on hlv/hlvx/hsv instructions
  target/riscv: Don't allow guest to write to htinst
  target/riscv: Convert MSTATUS MTL to GVA
  target/riscv: Fix the interrupt cause code
  target/riscv: Update the Hypervisor trap return/entry
  target/riscv: Update the CSRs to the v0.6 Hyp extension
  target/riscv: Only support a single VSXL length
  target/riscv: Only support little endian guests
  target/riscv: Support the v0.6 Hypervisor extension CRSs
  target/riscv: Return the exception from invalid CSR accesses
  target/riscv: Support the Virtual Instruction fault
