Subject: [RFC PATCH 5/5] LoongArch: Enable BPF_JIT and TEST_BPF in loongson3_defconfig
Date: Tue,  9 Aug 2022 10:53:00 +0800	[thread overview]
Message-ID: <1660013580-19053-6-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1660013580-19053-1-git-send-email-yangtiezhu@loongson.cn>

For now, BPF JIT for LoongArch is supported, update loongson3_defconfig to
enable BPF_JIT to allow the kernel to generate native code when a program
is loaded into the kernel, and also enable TEST_BPF to test BPF JIT.
