Subject: [PATCH v3 3/7] cmd: fru: fix a sandbox segfault issue
Date: Tue, 23 Aug 2022 14:52:56 -0700 [thread overview]
Message-ID: <20220823215300.1485789-4-quic_jaehyoo@quicinc.com> (raw)
In-Reply-To: <20220823215300.1485789-1-quic_jaehyoo@quicinc.com>
This command doesn't work with sandbox because direct memory access
causes a segfault error. Fix it up using map_sysmem().
