[PATCH v3 0/4] Nested virtualization fixes for QEMU

Posted by Anup Patel 1 year, 3 months ago

This series mainly includes fixes discovered while developing nested
virtualization running on QEMU.

These patches can also be found in the riscv_nested_fixes_v3 branch at:
https://github.com/avpatel/qemu.git

Changes since v2:
 - Dropped PATCH1 since it is already merged
 - Rebased on latest riscv-to-apply.next branch of Alistair

Changes since v1:
 - Added Alistair's Reviewed-by tags to appropriate patches
 - Added detailed comment block in PATCH4

Anup Patel (4):
  target/riscv: Update VS timer whenever htimedelta changes
  target/riscv: Don't clear mask in riscv_cpu_update_mip() for VSTIP
  target/riscv: No need to re-start QEMU timer when timecmp ==
    UINT64_MAX
  target/riscv: Ensure opcode is saved for all relevant instructions
