Subject: [PATCH 10/10] x86: correct/improve TSX controls
Date: Mon, 19 Dec 2022 11:48:31 +0100 [thread overview]
Message-ID: <1b04fb35-1f99-7353-4e8c-d643e8ffa975@suse.com> (raw)
In-Reply-To: <973d3274-7adc-3a7c-5aaa-916fd5adc093@suse.com>
TSXLDTRK takes RTM as a prereq. Additionally introduce an umbrella "tsx"
extension option covering both RTM and HLE, paralleling the "abm" one we
already have.
