Subject: [PATCH 01/26] hw/riscv: acpi: only create RHCT MMU entry for supported types
Date: Mon, 28 Apr 2025 09:34:16 +0200 [thread overview]
Message-ID: <20250428073442.315770-2-pbonzini@redhat.com> (raw)
In-Reply-To: <20250428073442.315770-1-pbonzini@redhat.com>
Do not create the RHCT MMU type entry for RV32 CPUs, since it
only has definitions for SV39/SV48/SV57. Likewise, check that
satp_mode_max_from_map() will actually return a valid value, skipping
the MMU type entry if all MMU types were disabled on the command line.
