Subject: [RFC PATCH 4/5] target/i386: Define specific PT feature set for IceLake-server and Snowridge
Date: Thu,  9 Sep 2021 22:41:49 +0800	[thread overview]
Message-ID: <20210909144150.1728418-5-xiaoyao.li@intel.com> (raw)
In-Reply-To: <20210909144150.1728418-1-xiaoyao.li@intel.com>

For IceLake-server, it's just the same as using the default PT
feature set since the default one is exact taken from ICX.

For Snowridge, define it according to real SNR silicon capabilities.
