This series does fixes and improvements to have nested virtualization
on QEMU RISC-V.
These patches can also be found in riscv_nested_fixes_v2 branch at:
https://github.com/avpatel/qemu.git
The RISC-V nested virtualization was tested on QEMU RISC-V using
Xvisor RISC-V which has required hypervisor support to run another
hypervisor as Guest/VM.
Changes since v1:
- Set write_gva to env->two_stage_lookup which ensures that for
HS-mode to HS-mode trap write_gva is true only for HLV/HSV
instructions
- Included "[PATCH 0/3] QEMU RISC-V priv spec version fixes"
patches in this series for easy review
- Re-worked PATCH7 to force disable extensions if required
priv spec version is not staisfied
- Added new PATCH8 to fix "aia=aplic-imsic" mode of virt machine
Anup Patel (8):
target/riscv: Fix csr number based privilege checking
target/riscv: Fix hstatus.GVA bit setting for traps taken from HS-mode
target/riscv: Set [m|s]tval for both illegal and virtual instruction
traps
target/riscv: Update [m|h]tinst CSR in riscv_cpu_do_interrupt()
target/riscv: Don't force update priv spec version to latest
target/riscv: Add dummy mcountinhibit CSR for priv spec v1.11 or
higher
target/riscv: Force disable extensions if priv spec version does not
match
hw/riscv: virt: Fix interrupt parent for dynamic platform devices
