From: Mohamed Mediouni Date: Mon, 21 Jul 2025 15:29:02 +0000 (+0200) Subject: target/arm: hvf: stubbing reads to LORC_EL1 X-Git-Tag: v10.1.0-rc1~9^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a7aa2af13e287e11cb2d73972353bfec161803a4;p=thirdparty%2Fqemu.git target/arm: hvf: stubbing reads to LORC_EL1 Linux zeroes LORC_EL1 on boot at EL2, without further interaction with FEAT_LOR afterwards. Stub out LORC_EL1 accesses as FEAT_LOR is a mandatory extension on Armv8.1+.
