Subject: [PATCH v5 20/26] PCI/AER: Refactor cper_print_aer() for use by CXL driver module
Date: Wed, 7 Jun 2023 17:16:45 -0500 [thread overview]
Message-ID: <20230607221651.2454764-21-terry.bowman@amd.com> (raw)
In-Reply-To: <20230607221651.2454764-1-terry.bowman@amd.com>
The CXL driver plans to use cper_print_aer() for logging restricted CXL
host (RCH) AER errors. cper_print_aer() is not currently exported and
therefore not usable by the CXL drivers built as loadable modules. Export
the cper_print_aer() function. Use the EXPORT_SYMBOL_NS_GPL() variant
to restrict the export to CXL drivers.
The CONFIG_ACPI_APEI_PCIEAER kernel config is currently used to enable
cper_print_aer(). cper_print_aer() logs the AER registers and is
useful in PCIE AER logging outside of APEI. Remove the
CONFIG_ACPI_APEI_PCIEAER dependency to enable cper_print_aer().
The cper_print_aer() function name implies CPER specific use but is useful
in non-CPER cases as well. Rename cper_print_aer() to pci_print_aer().
