Subject: [PATCH 1/2] target/riscv: Export sdtrig as an extension and ISA string
Date: Wed, 10 Jan 2024 09:32:02 +0530 [thread overview]
Message-ID: <20240110040203.1920924-2-hchauhan@ventanamicro.com> (raw)
In-Reply-To: <20240110040203.1920924-1-hchauhan@ventanamicro.com>
This patch makes the debug trigger (sdtrig) capability
as an extension and exports it as an ISA string. The sdtrig
extension may or may not be implemented in a system. The
-cpu rv64,sdtrig=<true/false>
option can be used to dynamicaly turn sdtrig extension
on or off.
