Note that existing two users of pr_info("") that I found are not using that as a workaround: efi.c is using that when it announced a list of EFI tables: efi: ACPI=0xadffe000 ACPI 2.0=0xadffe014 TPMFinalLog=0xadf2d000 ESRT=0xab70d618 SMBIOS=0xab70b000 SMBIOS 3.0=0xab709000 RNG=0xab707b98 TPMEventLog=0x9602c018 and uvesafb.c similarly uses it to print a list of conditionally-present strings. In both cases it is really a standalone message, not a continuation for something previously printed. In contrast, my patch deals with a continuation line. I wouldn't really like the decoded feature list to appear on the same line as the previous message, because it would end up quite long: [ 0.266332] pci 0000:00:00.2: AMD-Vi: Extended features (0x206d73ef22254ade): [ 0.266334] AMD-Vi: PPR X2APIC NX GT IA GA PC GA_vAPIC I think a good compromise is to change the first line from pci_info to pr_info, losing the pci bus address. I'll send a v2. Alexander _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
