From: Richard Henderson Date: Fri, 6 May 2022 18:02:30 +0000 (-0500) Subject: target/arm: Enable FEAT_Debugv8p4 for -cpu max X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=8fc756b6be0d0de777b2092d324907ced7365543;p=qmiga%2Fqemu.git target/arm: Enable FEAT_Debugv8p4 for -cpu max This extension concerns changes to the External Debug interface, with Secure and Non-secure access to the debug registers, and all of it is outside the scope of QEMU. Indicating support for this is mandatory with FEAT_SEL2, which we do implement.
