Subject: [patch 8/8] configs/debug: set CONFIG_DEBUG_INFO=y properly
Date: Fri, 04 Mar 2022 20:29:10 -0800 [thread overview]
Message-ID: <20220305042911.52087C004E1@smtp.kernel.org> (raw)
In-Reply-To: <20220304202822.d47f8084928321c83070d7d7@linux-foundation.org>
From: Qian Cai <quic_qiancai@quicinc.com>
Subject: configs/debug: set CONFIG_DEBUG_INFO=y properly
CONFIG_DEBUG_INFO can't be set by user directly, so set
CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y instead. Otherwise, we end up
with no debuginfo in vmlinux which is a big no-no for kernel debugging.
