Subject: [PATCH v3 12/14] x86/traps: Add Hygon Dhyana support
Date: Mon, 25 Mar 2019 21:31:55 +0800 [thread overview]
Message-ID: <48dc73b7ece7e33785b118eb1b0853eda0ff5b31.1553520193.git.puwen@hygon.cn> (raw)
In-Reply-To: <cover.1553520193.git.puwen@hygon.cn>
The Hygon Dhyana processor has the methold to get the last exception
source IP from MSR0000_01DD. So add support for it if the boot param
