This pull request is almost entirely an implementation of the draft hypervisor extension. This extension is still in draft and is expected to have incompatible changes before being frozen, but we've had good luck managing other RISC-V draft extensions in QEMU so far. Additionally, there's a fix to PCI addressing and some improvements to the M-mode timer. This boots linux and passes make check for me. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAl5do3gTHHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYiXhlD/9gtiGUT9QxnwygSAck2rLYJHN0rWLC 7FRUar9egPDQ9rtwYKYM5H9fqFzfAxoWc2CTGPPxm75fS49gmEU06p6jBM3gdnNf WGXPdwefeBhWHxuS0LoQodoLybNmB1H+prrZA6LjoQFbp6BHEdOzSeGBvrUvoYuZ MCX++mA39h3gRvuXQdMYdPec2DdP07cMRirpXUgzlGtQ5WYUK8fNMDYDNkc0vKQc aDFDnL7KHRgKt74Fs9LnlEUuZg5r8vEsf4h80SWwBxqDLbSUf9Sh/F8K1abxDUEo tAm/45mPwTXEbFtEGG9f7uHD6ul0GyoTnybCf/1EQgWUtrm6yhw9b69UUdziOW7/ LVFNjuX4zI175PP6pANb9QnPJnr+VRaCaBg+rXeju3OypkFNsQi6EwefkZFnn1Ye 9hteMOKNaiuYY5qcNXqskJ3j/lnoPTzNpsZKbDinyXARr/tslRqZdn1MU8J9FVUS M+w0qVgrHPHojmFAbzwKQIONExApiKBkhrV+K5tkbxNNnp3tYBqoLXW8HYpu4MWh PavscLRVdLzzBJ7AQHnSNmJVlgiAz/VwJh/v0KNhfwrQzE0XAxcCyUQ/1NMLTkjY CGP3jxV3Wnxf6BQObqrUEUKG0UOOwWmGhYe28suVt8ni4c8eDvZ/z6P+yxFj/v9q cn03WY6J3beQlw== =5W7J -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/palmer/tags/riscv-for-master-5.0-sf3' into staging RISC-V Patches for the 5.0 Soft Freeze, Part 3 This pull request is almost entirely an implementation of the draft hypervisor extension.
