Subject: [PATCH] riscv: Call set_satp_mode_max_supported in riscv_host_cpu_init
Date: Tue, 19 Sep 2023 09:57:32 +0200	[thread overview]
Message-ID: <mvm34zavbmb.fsf@suse.de> (raw)

When running in KVM mode with -cpu host, cfg.satp_mode.supported is not
initialized, causing an infinite loop in riscv_cpu_satp_mode_finalize.

Fixes: 6df3747a27 ("riscv: Introduce satp mode hw capabilities")
