From 6777877eb7a3290cf0a8a6b621e46f72f9d94b6b Mon Sep 17 00:00:00 2001 From: Terry Bowman Date: Wed, 18 Oct 2023 19:17:05 +0200 Subject: PCI/AER: Refactor cper_print_aer() for use by CXL driver module 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(). Also, update cxl_core to import CXL namespace imports.
