Subject: [PATCH v2 2/5] efi/cper: Export cper_mem_err_unpack() for CXL logging
Date: Thu, 23 Mar 2023 16:38:05 -0500 [thread overview]
Message-ID: <20230323213808.398039-3-terry.bowman@amd.com> (raw)
In-Reply-To: <20230323213808.398039-1-terry.bowman@amd.com>
The CXL driver plans to use cper_print_aer() for restricted CXL host (RCH)
logging. This is not currently possible because CXL is a loadable module
and cper_print_aer() depends on cper_mem_err_unpack() which is not
exported.
Export cper_mem_err_unpack() to enable cper_print_aer() usage in
CXL and other loadable modules.
