Subject: [edk2-devel] [PATCH v5 04/36] MdePkg: Add LoongArch64 local interrupt function set into BaseLib
Date: Thu, 28 Dec 2023 18:05:01 +0800 [thread overview]
Message-ID: <20231228100501.1756661-1-lichao@loongson.cn> (raw)
In-Reply-To: <20231228100351.1756165-1-lichao@loongson.cn>
Adding LoongArch local interrupt function set, which is used to control
the opening or closing of the local interrupt when the global interrupt
is enabled.
