Subject: [edk2-devel] [PATCH v2 04/30] MdePkg: Add LoongArch64 local interrupt function set into BaseLib
Date: Mon, 6 Nov 2023 11:26:57 +0800 [thread overview]
Message-ID: <20231106032657.2268149-1-lichao@loongson.cn> (raw)
In-Reply-To: <20231106032521.2251143-1-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.
