This means that 'aia_mode' will not reflect the actual AIA mode, retrieved in 'default_aia_mode', This is benign for now, but it will impact QMP query commands that will expose the 'aia_mode' value, retrieving the wrong value. Set 'aia_mode' to 'default_aia_mode' if we fail to change the AIA mode in KVM. While we're at it, rework the log/warning messages to be a bit less verbose. Instead of: KVM AIA: default mode is emul qemu-system-riscv64: warning: KVM AIA: failed to set KVM AIA mode We can use a single warning message: qemu-system-riscv64: warning: KVM AIA: failed to set KVM AIA mode 'auto', u= sing default host mode 'emul' Signed-off-by: Daniel Henrique Barboza Acked-by: Alistair Francis Message-ID: <20241028182037.290171-2-dbarboza@ventanamicro.com> Signed-off-by: Alistair Francis --- target/riscv/kvm/kvm-cpu.c | 22 +++++++++++++++------- 1 file changed, 15 insertions(+), 7 deletions(-) diff --git a/target/riscv/kvm/kvm-cpu.c b/target/riscv/kvm/kvm-cpu.c index 8233a32102..acc713c56a 100644 --- a/target/riscv/kvm/kvm-cpu.c +++ b/target/riscv/kvm/kvm-cpu.c @@ -1711,18 +1711,26 @@ void kvm_riscv_aia_create(MachineState *machine, ui= nt64_t group_shift, error_report("KVM AIA: failed to get current KVM AIA mode"); exit(1); } - qemu_log("KVM AIA: default mode is %s\n", - kvm_aia_mode_str(default_aia_mode)); =20 - if (default_aia_mode !=3D aia_mode) { + if (default_aia_mode =3D=3D aia_mode) { + qemu_log("KVM AIA: using default host mode '%s'\n", + kvm_aia_mode_str(default_aia_mode)); + } else { ret =3D kvm_device_access(aia_fd, KVM_DEV_RISCV_AIA_GRP_CONFIG, KVM_DEV_RISCV_AIA_CONFIG_MODE, &aia_mode, true, NULL); - if (ret < 0) - warn_report("KVM AIA: failed to set KVM AIA mode"); - else - qemu_log("KVM AIA: set current mode to %s\n", + if (ret < 0) { + warn_report("KVM AIA: failed to set KVM AIA mode '%s', using " + "default host mode '%s'", + kvm_aia_mode_str(aia_mode), + kvm_aia_mode_str(default_aia_mode)); + + /* failed to change AIA mode, use default */ + aia_mode =3D default_aia_mode; + } else { + qemu_log("KVM AIA: setting current mode to %s\n", kvm_aia_mode_str(aia_mode)); + } } =20 ret =3D kvm_device_access(aia_fd, KVM_DEV_RISCV_AIA_GRP_CONFIG, --=20 2.47.0
