Subject: [PATCH v2] i386/tdx: Build TDX only for 64-bit target
Date: Wed, 25 Jun 2025 15:33:10 +0800	[thread overview]
Message-ID: <20250625073310.2796298-1-xiaoyao.li@intel.com> (raw)

Build errors related to TDX were reported when QEMU built on 32-bit
host[1][2].

Since TDX cannot work on 32-bit host and it's also not worth supporting
TDX with 32-bit QEMU, limit TDX to 64-bit target only.
